The validity of the multi-informant approach to assessing child and adolescent mental health.

Abstract: Child and adolescent patients may display mental health concerns within some contexts and not others (e.g., home vs. school). Thus, understanding the specific contexts in which patients display concerns may assist mental health professionals in tailoring treatments to patients' needs. Consequently, clinical assessments often include reports from multiple informants who vary in the contexts in which they observe patients' behavior (e.g., patients, parents, teachers). Previous meta-analyses indicate that informants' reports correlate at low-to-moderate magnitudes. However, is it valid to interpret low correspondence among reports as indicating that patients display concerns in some contexts and not others? We meta-analyzed 341 studies published between 1989 and 2014 that reported cross-informant correspondence estimates, and observed low-to-moderate correspondence (mean internalizing: r = .25; mean externalizing: r = .30; mean overall: r = .28). Informant pair, mental health domain, and measurement method moderated magnitudes of correspondence. These robust findings have informed the development of concepts for interpreting multi-informant assessments, allowing researchers to draw specific predictions about the incremental and construct validity of these assessments. In turn, we critically evaluated research on the incremental and construct validity of the multi-informant approach to clinical child and adolescent assessment. In so doing, we identify crucial gaps in knowledge for future research, and provide recommendations for "best practices" in using and interpreting multi-informant assessments in clinical work and research. This article has important implications for developing personalized approaches to clinical assessment, with the goal of informing techniques for tailoring treatments to target the specific contexts where patients display concerns.

Appealing to fear: A meta-analysis of fear appeal effectiveness and theories.

Abstract: Fear appeals are a polarizing issue, with proponents confident in their efficacy and opponents confident that they backfire. We present the results of a comprehensive meta-analysis investigating fear appeals' effectiveness for influencing attitudes, intentions, and behaviors. We tested predictions from a large number of theories, the majority of which have never been tested meta-analytically until now. Studies were included if they contained a treatment group exposed to a fear appeal, a valid comparison group, a manipulation of depicted fear, a measure of attitudes, intentions, or behaviors concerning the targeted risk or recommended solution, and adequate statistics to calculate effect sizes. The meta-analysis included 127 articles (9% unpublished) yielding 248 independent samples (NTotal = 27,372) collected from diverse populations. Results showed a positive effect of fear appeals on attitudes, intentions, and behaviors, with the average effect on a composite index being random-effects d = 0.29. Moderation analyses based on prominent fear appeal theories showed that the effectiveness of fear appeals increased when the message included efficacy statements, depicted high susceptibility and severity, recommended one-time only (vs. repeated) behaviors, and targeted audiences that included a larger percentage of female message recipients. Overall, we conclude that (a) fear appeals are effective at positively influencing attitude, intentions, and behaviors; (b) there are very few circumstances under which they are not effective; and (c) there are no identified circumstances under which they backfire and lead to undesirable outcomes.

Is the Desire for Status a Fundamental Human Motive? A Review of the Empirical Literature

Abstract: The current review evaluates the status hypothesis, which states that that the desire for status is a fundamental motive. Status is defined as the respect, admiration, and voluntary deference individuals are afforded by others. It is distinct from related constructs such as power, financial success, and social belongingness. A review of diverse literatures lent support to the status hypothesis: People’s subjective well-being, self-esteem, and mental and physical health appear to depend on the level of status they are accorded by others. People engage in a wide range of goal-directed activities to manage their status, aided by myriad cognitive, behavioral, and affective processes; for example, they vigilantly monitor the status dynamics in their social environment, strive to appear socially valuable, prefer and select social environments that offer them higher status, and react strongly when their status is threatened. The desire for status also does not appear to be a mere derivative of the need to belong, as some theorists have speculated. Finally, the importance of status was observed across individuals who differed in culture, gender, age, and personality, supporting the universality of the status motive. Therefore, taken as a whole, the relevant evidence suggests that the desire for status is indeed fundamental.

The relation between short-term emotion dynamics and psychological well-being: A meta-analysis

Abstract: Not only how good or bad people feel on average, but also how their feelings fluctuate across time is crucial for psychological health. The last 2 decades have witnessed a surge in research linking various patterns of short-term emotional change to adaptive or maladaptive psychological functioning, often with conflicting results. A meta-analysis was performed to identify consistent relationships between patterns of short-term emotion dynamics-including patterns reflecting emotional variability (measured in terms of within-person standard deviation of emotions across time), emotional instability (measured in terms of the magnitude of consecutive emotional changes), and emotional inertia of emotions over time (measured in terms of autocorrelation)-and relatively stable indicators of psychological well-being or psychopathology. We determined how such relationships are moderated by the type of emotional change, type of psychological well-being or psychopathology involved, valence of the emotion, and methodological factors. A total of 793 effect sizes were identified from 79 articles (N = 11,381) and were subjected to a 3-level meta-analysis. The results confirmed that overall, low psychological well-being co-occurs with more variable (overall ρ = -.178), unstable (overall ρ = -.205), but also more inert (overall ρ = -.151) emotions. These effect sizes were stronger when involving negative compared with positive emotions. Moreover, the results provided evidence for consistency across different types of psychological well-being and psychopathology in their relation with these dynamical patterns, although specificity was also observed. The findings demonstrate that psychological flourishing is characterized by specific patterns of emotional fluctuations across time, and provide insight into what constitutes optimal and suboptimal emotional functioning.

Heritability of personality: A meta-analysis of behavior genetic studies.

Abstract: The aim of this meta-analysis was to systematize available findings in the field of personality heritability and test for possible moderator effects of study design, type of personality model, and gender on heritability estimates. Study eligibility criteria were: personality model, behavior genetic study design, self-reported data, essential statistical indicators, and independent samples. A total of 134 primary studies with 190 potentially independent effect sizes were identified. After exclusion of studies that did not meet inclusion criteria and/or met 1 of the exclusion criteria, the final sample included 62 independent effect sizes, representing more than 100, 000 participants of both genders and all ages. Data analyses were performed using the random-effects model, software program R package metafor. The average effect size was .40, indicating that 40% of individual differences in personality were due to genetic, while 60% are due to environmental influences. After correction for possible publication bias the conclusion was unaltered. Additional analyses showed that personality model and gender were not significant moderators of personality heritability estimate, while study design was a significant moderator with twin studies showing higher estimates, .47, compared to family and adoption studies, .22. Personality model also was not a significant moderator of heritability estimates for neuroticism or extraversion, 2 personality traits contained in most personality trait theories and/or models. This study is the first to empirically test and confirm moderator effect of study design on heritability estimates in the field of personality. Limitations of the study, as well as suggestion for future studies, are discussed.

Intergenerational transmission of self-regulation: A multidisciplinary review and integrative conceptual framework.

Abstract: This review examines mechanisms contributing to the intergenerational transmission of self-regulation. To provide an integrated account of how self-regulation is transmitted across generations, we draw from over 75 years of accumulated evidence, spanning case studies to experimental approaches, in literatures covering developmental, social, and clinical psychology, and criminology, physiology, genetics, and human and animal neuroscience (among others). First, we present a taxonomy of what self-regulation is and then examine how it develops— overviews that guide the main foci of the review. Next, studies supporting an association between parent and child self-regulation are reviewed. Subsequently, literature that considers potential social mechanisms of transmission, specifically parenting behavior, interparental (i.e., marital) relationship behaviors, and broader rearing influences (e.g., household chaos) is considered. Finally, evidence that prenatal programming may be the starting point of the intergenerational transmission of self-regulation is covered, along with key findings from the behavioral and molecular genetics literatures. To integrate these literatures, we introduce the self-regulation intergenerational transmission model, a framework that brings together prenatal, social/contextual, and neurobiological mechanisms (spanning endocrine, neural, and genetic levels, including gene-environment interplay and epigenetic processes) to explain the intergenerational transmission of self-regulation. This model also incorporates potential transactional processes between generations (e.g., children’s self-regulation and parent– child interaction dynamics that may affect parents’ self-regulation) that further influence intergenerational processes. In pointing the way forward, we note key future directions and ways to address limitations in existing work throughout the review and in closing. We also conclude by noting several implications for intervention work.

Inner speech : development, cognitive functions, phenomenology, and neurobiology.

Abstract: Inner speech—also known as covert speech or verbal thinking—has been implicated in theories of cognitive development, speech monitoring, executive function, and psychopathology. Despite a growing body of knowledge on its phenomenology, development, and function, approaches to the scientific study of inner speech have remained diffuse and largely unintegrated. This review examines prominent theoretical approaches to inner speech and methodological challenges in its study, before reviewing current evidence on inner speech in children and adults from both typical and atypical populations. We conclude by considering prospects for an integrated cognitive science of inner speech, and present a multicomponent model of the phenomenon informed by developmental, cognitive, and psycholinguistic considerations. Despite its variability among individuals and across the life span, inner speech appears to perform significant functions in human cognition, which in some cases reflect its developmental origins and its sharing of resources with other cognitive processes.

Anxiety, depression, and cigarette smoking: a transdiagnostic vulnerability framework to understanding emotion-smoking comorbidity.

Abstract: Research into the comorbidity between emotional psychopathology and cigarette smoking has often focused upon anxiety and depression's manifest symptoms and syndromes, with limited theoretical and clinical advancement. This article presents a novel framework to understanding emotion-smoking comorbidity. We propose that transdiagnostic emotional vulnerabilities-core biobehavioral traits reflecting maladaptive responses to emotional states that underpin multiple types of emotional psychopathology-link various anxiety and depressive psychopathologies to smoking. This framework is applied in a review and synthesis of the empirical literature on 3 transdiagnostic emotional vulnerabilities implicated in smoking: (a) anhedonia (Anh; diminished pleasure/interest in response to rewards), (b) anxiety sensitivity (AS; fear of anxiety-related sensations), and (c) distress tolerance (DT; ability to withstand distressing states). We conclude that Anh, AS, and DT collectively (a) underpin multiple emotional psychopathologies, (b) amplify smoking's anticipated and actual affect-enhancing properties and other mechanisms underlying smoking, (c) promote progression across the smoking trajectory (i.e., initiation, escalation/progression, maintenance, cessation/relapse), and (d) are promising targets for smoking intervention. After existing gaps are identified, an integrative model of transdiagnostic processes linking emotional psychopathology to smoking is proposed. The model's key premise is that Anh amplifies smoking's anticipated and actual pleasure-enhancing effects, AS amplifies smoking's anxiolytic effects, and poor DT amplifies smoking's distress terminating effects. Collectively, these processes augment the reinforcing properties of smoking for individuals with emotional psychopathology to heighten risk of smoking initiation, progression, maintenance, cessation avoidance, and relapse. We conclude by drawing clinical and scientific implications from this framework that may generalize to other comorbidities.

Gender differences in narcissism: A meta-analytic review.

Abstract: Despite the widely held belief that men are more narcissistic than women, there has been no systematic review to establish the magnitude, variability across measures and settings, and stability over time of this gender difference. Drawing on the biosocial approach to social role theory, a meta-analysis performed for Study 1 found that men tended to be more narcissistic than women (d = .26; k = 355 studies; N = 470,846). This gender difference remained stable in U.S. college student cohorts over time (from 1990 to 2013) and across different age groups. Study 1 also investigated gender differences in three facets of the Narcissistic Personality Inventory (NPI) to reveal that the narcissism gender difference is driven by the Exploitative/Entitlement facet (d = .29; k = 44 studies; N = 44,108) and Leadership/Authority facet (d = .20; k = 40 studies; N = 44,739); whereas the gender difference in Grandiose/Exhibitionism (d = .04; k = 39 studies; N = 42,460) was much smaller. We further investigated a less-studied form of narcissism called vulnerable narcissism—which is marked by low self-esteem, neuroticism, and introversion—to find that (in contrast to the more commonly studied form of narcissism found in the DSM and the NPI) men and women did not differ on vulnerable narcissism (d = −.04; k = 42 studies; N = 46,735). Study 2 used item response theory to rule out the possibility that measurement bias accounts for observed gender differences in the three facets of the NPI (N = 19,001). Results revealed that observed gender differences were not explained by measurement bias and thus can be interpreted as true sex differences. Discussion focuses on the implications for the biosocial construction model of gender differences, for the etiology of narcissism, for clinical applications, and for the role of narcissism in helping to explain gender differences in leadership and aggressive behavior. Readers are warned against overapplying small effect sizes to perpetuate gender stereotypes.

A quantitative meta-analysis of neurocognitive functioning in posttraumatic stress disorder.

Abstract: Posttraumatic stress disorder (PTSD) is associated with regional alterations in brain structure and function that are hypothesized to contribute to symptoms and cognitive deficits associated with the disorder. We present here the first systematic meta-analysis of neurocognitive outcomes associated with PTSD to examine a broad range of cognitive domains and describe the profile of cognitive deficits, as well as modifying clinical factors and study characteristics. This report is based on data from 60 studies totaling 4,108 participants, including 1,779 with PTSD, 1,446 trauma-exposed comparison participants, and 895 healthy comparison participants without trauma exposure. Effect-size estimates were calculated using a mixed-effects meta-analysis for 9 cognitive domains: attention/working memory, executive functions, verbal learning, verbal memory, visual learning, visual memory, language, speed of information processing, and visuospatial abilities. Analyses revealed significant neurocognitive effects associated with PTSD, although these ranged widely in magnitude, with the largest effect sizes in verbal learning (d = -.62), speed of information processing (d = -.59), attention/working memory (d = -.50), and verbal memory (d =-.46). Effect-size estimates were significantly larger in treatment-seeking than community samples and in studies that did not exclude participants with attention-deficit/hyperactivity disorder, and effect sizes were affected by between-group IQ discrepancies and the gender composition of the PTSD groups. Our findings indicate that consideration of neuropsychological functioning in attention, verbal memory, and speed of information processing may have important implications for the effective clinical management of persons with PTSD. Results are further discussed in the context of cognitive models of PTSD and the limitations of this literature. (PsycINFO Database Record (c) 2015 APA, all rights reserved)

Modern Attitudes Toward Older Adults in the Aging World: A Cross-Cultural Meta-Analysis

Abstract: Prevailing beliefs suggest that Eastern cultures hold older adults in higher esteem than Western cultures do, due to stronger collectivist traditions of filial piety However, in modern, industrialized societies, the strain presented by dramatic rises in population aging potentially threatens traditional cultural expectations Addressing these competing hypotheses, a literature search located 37 eligible papers, comprising samples from 23 countries and 21,093 total participants, directly comparing Easterners and Westerners (as classified per UN conventions) in their attitudes toward aging and the aged Contradicting conventional wisdom, a random-effects meta-analysis on these articles found such evaluations to be more negative in the East overall (standardized mean difference = -031) High heterogeneity in study comparisons suggested the presence of moderators; indeed, geographical region emerged as a significant moderating factor, with the strongest levels of senior derogation emerging in East Asia (compared with South and Southeast Asia) and non-Anglophone Europe (compared with North American and Anglophone Western regions) At the country level, multiple-moderator meta-regression analysis confirmed recent rises in population aging to significantly predict negative elder attitudes, controlling for industrialization per se over the same time period Unexpectedly, these analyses also found that cultural individualism significantly predicted relative positivity-suggesting that, for generating elder respect within rapidly aging societies, collectivist traditions may backfire The findings suggest the importance of demographic challenges in shaping modern attitudes toward elders-presenting considerations for future research in ageism, cross-cultural psychology, and even economic development, as societies across the globe accommodate unprecedented numbers of older citizens

Leisure engagement and subjective well-being: A meta-analysis.

Abstract: Numerous studies show a link between leisure engagement and subjective well-being (SWB). Drawing on common experiential features of leisure, psychological need theories, and bottom-up models of SWB, we suggest that leisure engagement influences SWB via leisure satisfaction. We examine the proposed cross-sectional relations and mediation model using random-effects meta-analyses that include all available populations. To provide a stronger test of causal influence, we also examine longitudinal relations between leisure satisfaction and SWB and effects of experimental leisure interventions on SWB using random effects meta-analyses of all available populations. Findings based on 37 effect sizes and 11,834 individuals reveal that leisure engagement and SWB are moderately associated (inverse-variance weighted r = .26) and mediated by leisure satisfaction. Cross-lagged regression analyses of longitudinal studies, controlling for prior SWB, reveal bottom-up effects of leisure satisfaction on SWB (β = .15) and top-down effects of SWB on leisure satisfaction (β = .16). Experimental studies reveal that leisure interventions enhance SWB (d = 1.02). Compared with working samples, retired samples exhibit a stronger relation between leisure engagement and SWB, and between leisure satisfaction and SWB. Measures of the frequency and diversity of leisure engagement are more strongly associated with SWB than measures of time spent in leisure. Overall, although not minimizing top-down influences, results are consistent with bottom-up models of SWB and suggest that the leisure domain is a potentially important target for enhancing SWB

Positive interventions: An emotion regulation perspective.

Abstract: The rapid growth of the literature on positive interventions to increase “happiness” has suggested the need for an overarching conceptual framework to integrate the many and apparently disparate findings. In this review, we used the process model of emotion regulation (Gross, 1998) to organize the existing literature on positive interventions and to advance theory by clarifying the mechanisms underlying their effectiveness. We have proposed that positive emotions can be increased both in the short- and longer-term through 5 families of emotion regulation strategies (i.e., situation selection, situation modification, attentional deployment, cognitive change, and response modulation), showing how these emotion regulation strategies can be applied before, during, and after positive emotional events. Regarding short-term increases in positive emotions, our review found that attentional deployment, cognitive change, and response modulation strategies have received the most empirical support, whereas more work is needed to establish the effectiveness of situation selection and situation modification strategies. Regarding longer-term increases in positive emotions, strategies such as situation selection during an event and attentional deployment before, during, and after an event have received strong empirical support and are at the center of many positive interventions. However, more work is needed to establish the specific benefits of the other strategies, especially situation modification. We argue that our emotion regulation framework clarifies existing interventions and points the way for new interventions that might be used to increase positive emotions in both nonclinical and clinical populations.

Identifying Organizational Identification as a Basis for Attitudes and Behaviors: A Meta-Analytic Review.

Abstract: Organizational identification has been argued to have a unique value in explaining individual attitudes and behaviors in organizations, as it involves the essential definition of entities (i.e., individual and organizational identities). This review seeks meta-analytic evidence of the argument by examining how this identity-relevant construct functions in the nexus of attitudinal/behavioral constructs. The findings show that, first, organizational identification is significantly associated with key attitudes (job involvement, job satisfaction, and affective organizational commitment) and behaviors (in-role performance and extra-role performance) in organizations. Second, in the classic psychological model of attitude-behavior relations (Fishbein & Ajzen, 1975), organizational identification is positioned as a basis from which general sets of those attitudes and behaviors are engendered; organizational identification has a direct effect on general behavior above and beyond the effect of general attitude. Third, the effects of organizational identification are moderated by national culture, a higher-level social context wherein the organization is embedded, such that the effects are stronger in a collectivistic culture than in an individualistic culture. Theoretical and practical implications of the findings and future research directions are discussed.

A neural reward prediction error revealed by a meta-analysis of ERPs using great grand averages.

Abstract: Economic approaches to decision making assume that people attach values to prospective goods and act to maximize their obtained value. Neuroeconomics strives to observe these values directly in the brain. A widely used valuation term in formal learning and decision-making models is the reward prediction error: the value of an outcome relative to its expected value. An influential theory (Holroyd & Coles, 2002) claims that an electrophysiological component, feedback related negativity (FRN), codes a reward prediction error in the human brain. Such a component should be sensitive to both the prior likelihood of reward and its magnitude on receipt. A number of studies have found the FRN to be insensitive to reward magnitude, thus questioning the Holroyd and Coles account. However, because of marked inconsistencies in how the FRN is measured, a meaningful synthesis of this evidence is highly problematic. We conducted a meta-analysis of the FRN's response to both reward magnitude and likelihood using a novel method in which published effect sizes were disregarded in favor of direct measurement of the published waveforms themselves, with these waveforms then averaged to produce "great grand averages." Under this standardized measure, the meta-analysis revealed strong effects of magnitude and likelihood on the FRN, consistent with it encoding a reward prediction error. In addition, it revealed strong main effects of reward magnitude and likelihood across much of the waveform, indicating sensitivity to unsigned prediction errors or "salience." The great grand average technique is proposed as a general method for meta-analysis of event-related potential (ERP).

A meta-analysis on age differences in risky decision making: Adolescents versus children and adults.

Abstract: Despite evident heightened adolescent risk-taking in real-life situations, not all experimental studies demonstrate that adolescents take more risks than children and adults on risky decision-making tasks. In the current 4 independent meta-analyses, neurodevelopmental imbalance models and fuzzy trace theory were used as conceptual frameworks to examine whether adolescents engage in more risk-taking than children and adults and whether early adolescents take more risks than children and mid-late adolescents on behavioral risk-taking tasks. Studies with at least 1 of the aforementioned age comparisons met the inclusion criteria. Consistent with imbalance models and fuzzy trace theory, results from a random-effects model showed that adolescents take more risks (g = .37) than adults, and early adolescents take more risks (g = .15) than mid-late adolescents. However, inconsistent with both perspectives, adolescents and children take equal levels of risk (g = -.00), and early adolescents and children also take equal levels of risk (g = .04). Meta-regression analyses revealed that, consistent with imbalance models, (a) adolescents take more risks than adults on hot tasks with immediate outcome feedback on rewards and losses; however, contrary to imbalance models but consistent with fuzzy trace theory, (b) adolescents take fewer risks than children on tasks with a sure/safe option. Shortcomings related to studies using behavioral risk-taking tasks are discussed. We suggest a hybrid developmental neuroecological model of risk-taking that includes a risk opportunity component to explain why adolescents take more risks than children in the real world but equal levels of risks as children in the laboratory.

Religion and morality.

Abstract: The relationship between religion and morality has long been hotly debated. Does religion make us more moral? Is it necessary for morality? Do moral inclinations emerge independently of religious intuitions? These debates, which nowadays rumble on in scientific journals as well as in public life, have frequently been marred by a series of conceptual confusions and limitations. Many scientific investigations have failed to decompose “religion” and “morality” into theoretically grounded elements; have adopted parochial conceptions of key concepts—in particular, sanitized conceptions of “prosocial” behavior; and have neglected to consider the complex interplay between cognition and culture. We argue that to make progress, the categories “religion” and “morality” must be fractionated into a set of biologically and psychologically cogent traits, revealing the cognitive foundations that shape and constrain relevant cultural variants. We adopt this fractionating strategy, setting out an encompassing evolutionary framework within which to situate and evaluate relevant evidence. Our goals are twofold: to produce a detailed picture of the current state of the field, and to provide a road map for future research on the relationship between religion and morality.

Compensatory control and the appeal of a structured world.

Abstract: People are motivated to perceive themselves as having control over their lives. Consequently, they respond to events and cognitions that reduce control with compensatory strategies for restoring perceived control to baseline levels. Prior theory and research have documented 3 such strategies: bolstering personal agency, affiliating with external systems perceived to be acting on the self's behalf, and affirming clear contingencies between actions and outcomes within the context of reduced control (here termed specific structure). We propose a 4th strategy: affirming nonspecific structure, or seeking out and preferring simple, clear, and consistent interpretations of the social and physical environments. Formulating this claim suggests that people will respond to reduced control by affirming structured interpretations that are unrelated to the control-reducing condition, and even those that entail otherwise adverse outcomes (e.g., pessimistic health prospects). Section 1 lays the conceptual foundation for our review, situating the proposed phenomenon in the literatures on control motivation and threat-compensation mechanisms. Section 2 reviews studies that have demonstrated that trait and state variations in perceived control predict a wide range of epistemic structuring tendencies, including pattern recognition and causal reasoning. We posit that these tendencies reflect a common desire for a structured understanding of one's environment. Accordingly, a new meta-analysis spanning the reviewed studies (k = 55) revealed that control reduction predicts nonspecific structure affirmation with a moderate effect size (r = .25). Section 3 reviews research on individual differences and situational moderators of this effect. The discussion addresses the interplay of compensatory control strategies and practical implications.

The effects of feedback on energy conservation: A meta-analysis.

Abstract: Feedback has been studied as a strategy for promoting energy conservation for more than 30 years, with studies reporting widely varying results. Literature reviews have suggested that the effectiveness of feedback depends on both how and to whom it is provided; yet variations in both the type of feedback provided and the study methodology have made it difficult for conclusions to be drawn. The current article analyzes past theoretical and empirical research on both feedback and proenvironmental behavior to identify unresolved issues, and utilizes a meta-analysis of 42 feedback studies published between 1976 and 2010 to test a set of hypotheses about when and how feedback about energy usage is most effective. Results indicate that feedback is effective overall, r = .071, p < .001, but with significant variation in effects (r varied from -.080 to .480). Several treatment variables were found to moderate this relationship, including frequency, medium, comparison message, duration, and combination with other interventions (e.g., goal, incentive). Overall, results provide further evidence of feedback as a promising strategy to promote energy conservation and suggest areas in which future research should focus to explore how and for whom feedback is most effective.

The effects of cognitive behavioral therapy as an anti-depressive treatment is falling: A meta-analysis.

Abstract: A meta-analysis examining temporal changes (time trends) in the effects of cognitive behavioral therapy (CBT) as a treatment for unipolar depression was conducted. A comprehensive search of psychotherapy trials yielded 70 eligible studies from 1977 to 2014. Effect sizes (ES) were quantified as Hedge's g based on the Beck Depression Inventory (BDI) and the Hamilton Rating Scale for Depression (HRSD). Rates of remission were also registered. The publication year of each study was examined as a linear metaregression predictor of ES, and as part of a 2-way interaction with other moderators (Year × Moderator). The average ES of the BDI was 1.58 (95% CI [1.43, 1.74]), and 1.69 for the HRSD (95% CI [1.48, 1.89]). Subgroup analyses revealed that women profited more from therapy than did men (p < .05). Experienced psychologists (g = 1.55) achieved better results (p < .01) than less experienced student therapists (g = 0.98). The metaregressions examining the temporal trends indicated that the effects of CBT have declined linearly and steadily since its introduction, as measured by patients' self-reports (the BDI, p < .001), clinicians' ratings (the HRSD, p < .01) and rates of remission (p < .01). Subgroup analyses confirmed that the declining trend was present in both within-group (pre/post) designs (p < .01) and controlled trial designs (p = .02). Thus, modern CBT clinical trials seemingly provided less relief from depressive symptoms as compared with the seminal trials. Potential causes and possible implications for future studies are discussed. (PsycINFO Database Record

Global processing takes time: A meta-analysis on local-global visual processing in ASD.

Abstract: What does an individual with autism spectrum disorder (ASD) perceive first: the forest or the trees? In spite of 30 years of research and influential theories like the weak central coherence (WCC) theory and the enhanced perceptual functioning (EPF) account, the interplay of local and global visual processing in ASD remains only partly understood. Research findings vary in indicating a local processing bias or a global processing deficit, and often contradict each other. We have applied a formal meta-analytic approach and combined 56 articles that tested about 1,000 ASD participants and used a wide range of stimuli and tasks to investigate local and global visual processing in ASD. Overall, results show no enhanced local visual processing nor a deficit in global visual processing. Detailed analysis reveals a difference in the temporal pattern of the local–global balance, that is, slow global processing in individuals with ASD. Whereas task-dependent interaction effects are obtained, gender, age, and IQ of either participant groups seem to have no direct influence on performance. Based on the overview of the literature, suggestions are made for future research.

Toward a psychology of human–animal relations.

Abstract: Nonhuman animals are ubiquitous to human life, and permeate a diversity of social contexts by providing humans with food and clothing, serving as participants in research, improving healing, and offering entertainment, leisure, and companionship. Despite the impact that animals have on human lives and vice versa, the field of psychology has barely touched upon the topic of human–animal relations as an important domain of human activity. We review the current state of research on human–animal relations, showing how this body of work has implications for a diverse range of psychological themes including evolutionary processes, development, normative factors, gender and individual differences, health and therapy, and intergroup relations. Our aim is to highlight human–animal relations as a domain of human life that merits theoretical and empirical attention from psychology as a discipline.

A meta-analysis on gender differences in negotiation outcomes and their moderators.

Abstract: This meta-analysis investigates gender differences in economic negotiation outcomes. As suggested by role congruity theory, we assume that the behaviors that increase economic negotiation outcomes are more congruent with the male as compared with the female gender role, thereby presenting challenges for women’s negotiation performance and reducing their outcomes. Importantly, this main effect is predicted to be moderated by person-based, situation-based, and task-based influences that make effective negotiation behavior more congruent with the female gender role, which should in turn reduce or even reverse gender differences in negotiation outcomes. Using a multilevel modeling approach, this meta-analysis includes 123 effect sizes (overall N 10,888, including undergraduate and graduate students as well as businesspeople). Studies were included when they enabled the calculation of an effect size reflecting gender differences in achieved economic negotiation outcomes. As predicted, men achieved better economic outcomes than women on average, but gender differences strongly depended on the context: Moderator analysis revealed that gender differences favoring men were reduced when negotiators had negotiation experience, when they received information about the bargaining range, and when they negotiated on behalf of another individual. Moreover, gender differences were reversed under conditions of the lowest predicted role incongruity for women. In conclusion, gender differences in negotiations are contextually bound and can be subject to change. Future research is needed that investigates the underlying mechanisms of new moderators revealed in the current research (e.g., experience). Implications for theoretical explanations of gender differences in negotiation outcomes, for gender inequalities in the workplace, and for future research are discussed.

Interoceptive dysfunction: toward an integrated framework for understanding somatic and affective disturbance in depression.

Abstract: Depression is characterized by disturbed sleep and eating, a variety of other nonspecific somatic symptoms, and significant somatic comorbidities. Why there is such close association between cognitive and somatic dysfunction in depression is nonetheless poorly understood. An explosion of research in the area of interoception-the perception and interpretation of bodily signals-over the last decade nonetheless holds promise for illuminating what have until now been obscure links between the social, cognitive-affective, and somatic features of depression. This article reviews rapidly accumulating evidence that both somatic signaling and interoception are frequently altered in depression. This includes comparative studies showing vagus-mediated effects on depression-like behaviors in rodent models as well as studies in humans indicating both dysfunction in the neural substrates for interoception (e.g., vagus, insula, anterior cingulate cortex) and reduced sensitivity to bodily stimuli in depression. An integrative framework for organizing and interpreting this evidence is put forward which incorporates (a) multiple potential pathways to interoceptive dysfunction; (b) interaction with individual, gender, and cultural differences in interoception; and (c) a developmental psychobiological systems perspective, emphasizing likely differential susceptibility to somatic and interoceptive dysfunction across the lifespan. Combined with current theory and evidence, it is suggested that core symptoms of depression (e.g., anhedonia, social deficits) may be products of disturbed interoceptive-exteroceptive integration. More research is nonetheless needed to fully elucidate the relationship between mind, body, and social context in depression.

The effects of psychological distance on abstraction: Two meta-analyses

Abstract: Psychological distance and abstraction both represent key variables of considerable interest to researchers across cognitive, social, and developmental psychology. Moreover, largely inspired by construal level theory, numerous experiments across multiple fields have now connected these 2 constructs, examining how psychological distance affects the level of abstraction at which people mentally represent the world around them. The time is clearly ripe for a quantitative synthesis to shed light on the relation between these constructs and investigate potential moderators. To this end, we conducted 2 meta-analyses of research examining the effects of psychological distance on abstraction and its downstream consequences. Across 106 papers containing a total of 267 experiments, our results showed a reliable and medium-sized effect of psychological distance on both level of abstraction in mental representation and the downstream consequences of abstraction. Importantly, these effects replicate across time, researchers, and settings. Our analyses also identified several key moderators, including the size of the difference in distance between 2 levels of a temporal distance manipulation and the dependent variable's capacity to tap processing of both abstract and concrete features (rather than only one or the other). We discuss theoretical and methodological implications, and highlight promising avenues for future research.

Intergenerational cultural conflict, mental health, and educational outcomes among Asian and Latino/a Americans: Qualitative and meta-analytic review.

Abstract: Among immigrant Asian and Latino groups, the contrast between collectivism in traditional heritage and individualism in the mainstream American cultures presents unique challenges for their family relationships. This systematic review was designed to answer 3 fundamental questions: to what extent do(es) (a) acculturation mismatch (AM) correlate with intergenerational cultural conflict (ICC); (b) ICC correlate with offspring's mental health and educational outcomes; and (c) demographic and study characteristics moderate these relationships. Sixty-one research reports were reviewed, with 68 independent study samples (N = 14,453; 41 and 27 Asian and Latino/a samples, respectively) subjected to 3 meta-analyses. AM positively correlated with ICC (r = .23), which in turn negatively correlated with offspring mental health (r = -.20) and educational outcomes (r = -.09). Findings provided support for acculturation gap-distress theory. While these effect size estimates were small, participant and methodological variables affected their magnitude. Contrary to findings on intergenerational conflict within mainstream non-immigrant families, the relationships among AM, ICC, and mental health were larger in young adult than adolescent groups within immigrant families. ICC significantly correlated with internalizing problems and adaptive functioning, but not externalizing problems. AM was more closely related to ICC among women and second-generation immigrant offspring. AM and ICC were more problematic among offspring who were low-risk and lived in less ethnically disperse regions, particularly when studied in cross-sectional studies. Effect sizes also differed significantly across measurement tools for the key constructs. Limitations to generalizability (few studies on educational outcomes, relative under-representation of Latino/a to Asian American samples), and implications for intervention and future research are discussed.

Effects of sleep on memory for conditioned fear and fear extinction.

Abstract: Learning and memory for extinction of conditioned fear is a basic mammalian mechanism for regulating negative emotion. Sleep promotes both the consolidation of memory and the regulation of emotion. Sleep can influence consolidation and modification of memories associated with both fear and its extinction. After brief overviews of the behavior and neural circuitry associated with fear conditioning, extinction learning, and extinction memory in the rodent and human, interactions of sleep with these processes will be examined. Animal and human studies suggest that sleep can serve to consolidate both fear and extinction memory. In humans, sleep also promotes generalization of extinction memory. Time-of-day effects on extinction learning and generalization are also seen. Rapid eye movement (REM) may be a sleep stage of particular importance for the consolidation of both fear and extinction memory as evidenced by selective REM deprivation experiments. REM sleep is accompanied by selective activation of the same limbic structures implicated in the learning and memory of fear and extinction. Preliminary evidence also suggests extinction learning can take place during slow wave sleep. Study of low-level processes such as conditioning, extinction, and habituation may allow sleep effects on emotional memory to be identified and inform study of sleep's effects on more complex, emotionally salient declarative memories. Anxiety disorders are marked by impairments of both sleep and extinction memory. Improving sleep quality may ameliorate anxiety disorders by strengthening naturally acquired extinction. Strategically timed sleep may be used to enhance treatment of anxiety by strengthening therapeutic extinction learned via exposure therapy. (PsycINFO Database Record

Sleep and Motor Learning: Is There Room for Consolidation?

Abstract: It is widely believed that sleep is critical to the consolidation of learning and memory. In some skill domains, performance has been shown to improve by 20% or more following sleep, suggesting that sleep enhances learning. However, recent work suggests that those performance gains may be driven by several factors that are unrelated to sleep consolidation, inviting a reconsideration of sleep’s theoretical role in the consolidation of procedural memories. Here we report the first comprehensive investigation of that possibility for the case of motor sequence learning. Quantitative meta-analyses involving 34 articles, 88 experimental groups and 1,296 subjects confirmed the empirical pattern of a large performance gain following sleep and a significantly smaller gain following wakefulness. However, the results also confirm strong moderating effects of 4 previously hypothesized variables: averaging in the calculation of prepost gain scores, build-up of reactive inhibition over training, time of testing, and training duration, along with 1 supplemental variable, elderly status. With those variables accounted for, there was no evidence that sleep enhances learning. Thus, the literature speaks against, rather than for, the enhancement hypothesis. Overall there was relatively better performance after sleep than after wakefulness, suggesting that sleep may stabilize memory. That effect, however, was not consistent across different experimental designs. We conclude that sleep does not enhance motor learning and that the role of sleep in the stabilization of memory cannot be conclusively determined based on the literature to date. We discuss challenges and opportunities for the field, make recommendations for improved experimental design, and suggest approaches to data analysis that eliminate confounds due to averaging over online learning.

Cognitive aspects of young children's experience of economic disadvantage.

Abstract: Economic disadvantage is a well-studied risk factor for poorer behavioral and academic functioning in young children. Although the mechanisms by which disadvantage impacts children have long been of interest to researchers, studies to date have predominantly focused on mechanisms that are external to the child (e.g., parental depression, marital conflict). Very few studies have examined the internal, cognitive aspects of the experience of economic disadvantage, and almost none have considered how the effects of disadvantage on children's functioning might be mediated through cognitive processes. This article provides a framework for research into cognitive and social-cognitive mediators of economic disadvantage operating in early-to-middle childhood. The initial section of the article briefly reviews and summarizes the extant literature on childhood poverty and its effects. The second section reviews the evidence that preschool-aged children have the requisite cognitive abilities to recognize social inequality in their environments, to be aware of stereotypes related to social class, and to connect these social concepts to their own experience. The third section reviews and evaluates the small literature on children's appraisals, attributions, stereotypes, and perceptions of or about poverty and inequality. The fourth section defines and evaluates the literature on 2 social-cognitive processes-stereotype threat and status anxiety-that are hypothesized to mediate the effects of economic disadvantage on children's functioning. The article concludes with a series of proposed questions and hypotheses for future research, and elaborates on the potential implications of the proposed area of research. (PsycINFO Database Record

When it comes to lifestyle recommendations, more is sometimes less: a meta-analysis of theoretical assumptions underlying the effectiveness of interventions promoting multiple behavior domain change.

Abstract: A meta-analysis of 150 research reports summarizing the results of multiple behavior domain interventions examined theoretical predictions about the effects of the included number of recommendations on behavioral and clinical change in the domains of smoking, diet, and physical activity. The meta-analysis yielded 3 main conclusions. First, there is a curvilinear relation between the number of behavioral recommendations and improvements in behavioral and clinical measures, with a moderate number of recommendations producing the highest level of change. A moderate number of recommendations is likely to be associated with stronger effects because the intervention ensures the necessary level of motivation to implement the recommended changes, thereby increasing compliance with the goals set by the intervention, without making the intervention excessively demanding. Second, this curve was more pronounced when samples were likely to have low motivation to change, such as when interventions were delivered to nonpatient (vs. patient) populations, were implemented in nonclinic (vs. clinic) settings, used lay community (vs. expert) facilitators, and involved group (vs. individual) delivery formats. Finally, change in behavioral outcomes mediated the effects of number of recommended behaviors on clinical change. These findings provide important insights that can help guide the design of effective multiple behavior domain interventions.
