Behavioral inhibition, sustained attention, and executive functions: Constructing a unifying theory of ADHD.

Abstract: Attention deficit hyperactivity disorder (ADHD) comprises a deficit in behavioral inhibition. A theoretical model is constructed that links inhibition to 4 executive neuropsychological functions that appear to depend on it for their effective execution: (a) working memory, (b) self-regulation of affect-motivation-arousal, (c) internalization of speech, and (d) reconstitution (behavioral analysis and synthesis). Extended to ADHD, the model predicts that ADHD should be associated with secondary impairments in these 4 executive abilities and the motor control they afford. The author reviews evidence for each of these domains of functioning and finds it to be strongest for deficits in behavioral inhibition, working memory, regulation of motivation, and motor control in those with ADHD. Although the model is promising as a potential theory of self-control and ADHD, far more research is required to evaluate its merits and the many predictions it makes about ADHD.

Models of the Self: Self-Construals and Gender

Abstract: The authors first describe individual differences in the structure of the self. In the independent self-construal, representations of others are separate from the self. In the interdependent self-construal, others are considered part of the self (H. Markus & S. Kitayama, 1991). In general, men in the United States are thought to construct and maintain an independent self-construal, whereas women are thought to construct and maintain an interdependent self-construal. The authors review the psychological literature to demonstrate that many gender differences in cognition, motivation, emotion, and social behavior may be explained in terms of men's and women's different self-construals. Recognition of the interdependent self-construal as a possible alternative conception of the self may stimulate new investigations into the ways the self influences a person's thinking, feeling, and behaving.

Shaping Perceptions to Motivate Healthy Behavior: The Role of Message Framing

Abstract: Health-relevant communications can be framed in terms of the benefits (gains) or costs (losses) associated with a particular behavior, and the framing of such persuasive messages influences health decision making. Although to ask people to consider a health issue in terms of associated costs is considered an effective way to motivate behavior, empirical findings are inconsistent. In evaluating the effectiveness of framed health messages, investigators must appreciate the context in which health-related decisions are made. The influence of framed information on decision making is contingent on people, first, internalizing the advocated frame and, then, on the degree to which performing a health behavior is perceived as risky. The relative effectiveness of gain-framed or loss-framed appeals depends, in part, on whether a behavior serves an illness-detecting or a health-affirming function. Finally, the authors discuss the cognitive and affective processes that may mediate the influence of framed information on judgment and behavior.

Intelligence, personality, and interests: Evidence for overlapping traits.

Abstract: The authors review the development of the modern paradigm for intelligence assessment and application and consider the differentiation between intelligence-as-maximal performance and intelligence-as-typical performance. They review theories of intelligence, personality, and interest as a means to establish potential overlap. Consideration of intelligence-as-typical performance provides a basis for evaluation of intelligence-personality and intelligence-interest relations. Evaluation of relations among personality constructs, vocational interests, and intellectual abilities provides evidence for communality across the domains of personality of J. L. Holland's (1959) model of vocational interests. The authors provide an extensive meta-analysis of personality-intellectual ability correlations, and a review of interest-intellectual ability associations. They identify 4 trait complexes: social, clerical/conventional, science/math, and intellectual/cultural.

Toward a theory of episodic memory: the frontal lobes and autonoetic consciousness.

Abstract: Adult humans are capable of remembering prior events by mentally traveling back in time to re-experience those events. In this review, the authors discuss this and other related capabilities, considering evidence from such diverse sources as brain imaging, neuropsychological experiments, clinical ob

A stitch in time: Self-regulation and proactive coping.

Abstract: In a conceptual and temporal framework, derived from research on social cognition, social interaction, and stress and coping, the authors analyze the processes through which people anticipate or detect potential stressors and act in advance to prevent them or to mute their impact (proactive coping). The framework specifies five stages in proactive coping: (1) resource accumulation, (2) recognition of potential stressors, (3) initial appraisal, (4) preliminary coping efforts, and (5) elicitation and use of feedback concerning initial efforts. The authors detail the role of individual differences skills, and resources at each stage. They highlight the unique predictions afforded by a focus on proactive coping and the importance of understanding how people avoid and offset potential stressors.

The Emerging Conceptualization of Groups as Information Processors

Abstract: A selective review of research highlights the emerging view of groups as information processors. In this review, the authors include research on processing objectives, attention, encoding, storage, retrieval, processing, response, feedback, and learning in small interacting task groups. The groups as information processors perspective underscores several characteristic dimensions of variability in group performance of cognitive tasks, namely, commonality-uniqueness of information, convergence-diversity of ideas, accentuation-attenuation of cognitive processes, and belongingness-distinctiveness of members. A combination of contributions framework provides an additional conceptualization of information processing in groups. The authors also address implications, caveats, and questions for future research and theory regarding groups as information processors.

The Self-Reference Effect in Memory: A Meta-Analysis

Abstract: In this review, the authors examine the basis for the mnemonic superiority that results from relating material to the self. A meta-analysis confirms the expected self-reference effect (SRE) in memory, with self-referent encoding strategies yielding superior memory relative to both semantic and other-referent encoding strategies. Consistent with theory and research that suggest self-reference (SR) produces both organized and elaborate processing, the SRE was smaller (a) when SR is compared with other-reference (OR) rather than semantic encoding and (b) when the comparison tasks promote both organization and elaboration. Thus, the SRE appears to result primarily because the self is a well-developed and often-used construct that promotes elaboration and organization of encoded information. The authors discuss the implications of these and other findings for theories of the SRE and for future research.

A meta-analysis of outcome studies comparing bona fide psychotherapies: Empiricially, "all must have prizes."

Abstract: This recta-analysis tested the Dodo bird conjecture, which states that when psychotherapies intended to be therapeutic are compared, the true differences among all such treatments are 0. Based on comparisons between treatments culled from 6 journals, it was found that the effect sizes were homogeneously distributed about 0, as was expected under the Dodo bird conjecture, and that under the most liberal assumptions, the upper bound of the true effect was about .20. Moreover, the effect sizes (a) were not related positively to publication date, indicating that improving research methods were not detecting effects, and (b) were not related to the similarity of the treatments, indicating that more dissimilar treatments did not produce larger effects, as would be expected if the Dodo bird conjecture was false. The evidence from these analyses supports the conjecture that the efficacy of bona fide treatments are roughly equivalent. In 1936, Rosenzweig proposed that common factors were responsible for the efficacy of psychotherapy and used the conclusion of the Dodo bird from Alice in Wonderland (Carroll, 1865/1962) to emphasize this point: "At last the Dodo said, 'Everybody has won, and all must have prizes' " (p. 412). Later, Luborsky, Singer, and Luborsky ( 1975 ) reviewed the psychotherapy outcome literature, found that the psychotherapies reviewed were generally equivalent in terms of their outcomes, and decreed that the Dodo bird was correct. Since Luborsky et al.'s seminal review, the equivalence of outcome in psychotherapy has been called the Dodo bird effect. To many interested in the technical aspects of particular psychotherapies, the Dodo bird effect was distasteful and, on the face of it, unbelievable: If the indiscriminate distribution of prizes argument carried true conviction . . . we end up with the same advice for everyone"Regardless of the nature of your problem seek any form of psychotherapy." This is absurd. We doubt whether even the strongest advocates of the Dodo bird argument dispense this advice. (Rachman & Wilson, 1980, p. 167)

Meta-analyses of age–cognition relations in adulthood: Estimates of linear and nonlinear age effects and structural models.

Abstract: A meta-analysis was conducted on 91 studies to derive a correlation matrix for adult age, speed of processing, primary-working memory, episodic memory, reasoning, and spatial ability. Structural equation modeling with a single latent common cognitive factor showed that all cognitive measures shared substantial portions of age-related variance. A mediational model revealed that speed of processing and primary-working memory appear to be important mediators of age-related differences in the other measures. However, not all of the age-related influences were mediated. An examination of quadratic age effects and correlational patterns for subsamples under and over 50 years of age revealed that (a) negative age-cognition relations were significant for the 18- to 50-year-old sample and (b) the age-related decline accelerated significantly over the adult life span for variables assessing speed, reasoning, and episodic memory.

Friendships and adaptation in the life course.

Abstract: To consider friendships and their significance through the life course requires, first, differentiation of deep structure (i.e., reciprocity) from surface structure (i.e., the social exchange) and, second, assessment within a multifaceted framework that simultaneously emphasizes having friends, the identity of one's friends, and relationship quality. Having friends is correlated with a sense of well being across the life span, but developmental outcome also depends on the identity of one's friends as well as the quality of one's relationships with them. Greater attention needs to be given to the manner in which friendships differ from one another, continuities and changes across major developmental transitions, and differentiation of developmental pathways through which friendship experience contributes to individual outcome.

Developmental and social influences on young girls' early problem behavior.

Abstract: A developing body of research suggests that there are few sex differences in the rate and severity of problem behavior in early childhood, but clear sex differences emerge at about 4 years of age. The authors explore 2 hypotheses to further the understanding of emerging sex differences in problem behavior across the first 5 years of life. The first posits that the change in girls' problem behavior from infancy to school entry represents a channeling of early problem behavior into predominantly internalizing problems as a result of socialization. The second hypothesis is that the change in girls' early problem behavior during the preschool period results from the more rapid biological, cognitive, and social-emotional development of girls relative to boys. The authors review research on the influence of parents, teachers, and peers on girls' behavior from infancy to preschool regarding the first hypothesis, whereas they review studies of sex differences in developmental processes to test the second. They find moderate support for both hypotheses and present a comprehensive theory of girls' developmental psychopathology that integrates social and developmental influences.

Embarrassment: its distinct form and appeasement functions.

Abstract: The authors address 2 questions about embarrassment. First, Is embarrassment a distinct emotion? The evidence indicates that the antecedents, experience, and display of embarrassment, and to a limited extent its autonomic physiology, are distinct from shame, guilt, and amusement and share the dynamic, temporal characteristics of emotion. Second, What are the theoretical accounts of embarrassment? Three accounts focus on the causes of embarrassment, positioning that it follows the loss of self-esteem, concern for others' evaluations, or absence of scripts to guide interactions. A fourth account focuses on the effects of the remedial actions of embarrassment, which correct preceding transgressions. A fifth account focuses on the functional parallels between embarrassment and nonhuman appeasement. The discussion focuses on unanswered questions about embarrassment.

Social cognition in schizophrenia

Abstract: The study of social cognition in schizophrenia may augment the understanding of clinical and behavioral manifestations of the disorder. In this article, the authors describe social cognition and differentiate it from nonsocial cognition. They garner evidence to support the role of social cognition in schizophrenia: Nonsocial information-processing models are limited to explain social dysfunction in schizophrenia, measures of social cognition may contribute greater variance to social functioning than measures of nonsocial cognition, task performance on nonsocial-cognitive measures may not parallel performance on social-cognitive tasks, and symptomatology may be best understood within a social-cognitive framework. They describe the potential implications of a social-cognitive model of schizophrenia for the etiology and development of the disorder.

Outcome, attrition, and family-couples treatment for drug abuse: a meta-analysis and review of the controlled, comparative studies.

Abstract: This review synthesizes drug abuse outcome studies that included a family-couples therapy treatment condition. The meta-analytic evidence, across 1,571 cases involving an estimated 3,500 patients and family members, favors family therapy over (a) individual counseling or therapy, (b) peer group therapy, and (c) family psychoeducation. Family therapy is as effective for adults as for adolescents and appears to be a cost-effective adjunct to methadone maintenance. Because family therapy frequently had higher treatment retention rates than did nonfamily therapy modalities, it was modestly penalized in studies that excluded treatment dropouts from their analyses, as family therapy apparently had retained a higher proportion of poorer prognosis cases. Re-analysis, with dropouts regarded as failures, generally offset this artifact. Two statistical effect size measures to contend with attrition (dropout d and total attrition d) are offered for future researchers and policy makers.

What do men want ? Gender differences and two spheres of belongingness : Comment on Cross and Madson (1997)

Abstract: In response to S. E. Cross and L. Madson's (1997) suggestion that men's behaviors reflect a desire for independence and separateness, the authors propose that those same behaviors are designed to form connections with other people but in a broader social sphere. Women's sociality is oriented toward dyadic close relationships, whereas men's sociality is oriented toward a larger group. Gender differences in aggression, helping behavior, desire for power, uniqueness, self-representations, interpersonal behavior, and intimacy fit this view.

Infants' perception of expressive behaviors: differentiation of multimodal information.

Abstract: The literature on infants' perception of facial and vocal expressions, combined with data from studies on infant-directed speech, mother-infant interaction, and social referencing, supports the view that infants come to recognize the affective expressions of others through a perceptual differentiation process. Recognition of affective expressions changes from a reliance on multimodally presented information to the recognition of vocal expressions and then of facial expressions alone. Face or voice properties become differentiated and discriminated from the whole, standing for the entire emotional expression. Initially, infants detect information that potentially carries the meaning of emotional expressions; only later do infants discriminate and then recognize those expressions. The author reviews data supporting this view and draws parallels between the perceptions of affective expressions and of speech.

Representation of space in blind persons: vision as a spatial sense?

Abstract: Some researchers of studies of the incidence of early visual experience on spatial abilities have demonstrated profound spatial deficits in early blind participants, whereas others have not found evidence of deleterious effects of early visual deprivation. The aims of this article are to (a) consider the theoretical background of these studies, (b) take stock of the divergent data, and (c) propose new means of investigation. The authors examine the reasons why vision plays a critical role in spatial cognition. They review the literature data. They also review the factors that could account for the discrepant data and the effects of lack of early visual experience on brain functioning. They propose that the study of strategies is a valuable option to obtain insight into early blind persons' spatial impairment. The ability to move about independently in space, to localize places that cannot be directly perceived because they are hidden or remote, and to plan trajectories on the basis of this knowledge is of great importance in everyday human life activities. It is not necessary to refer to sophisticated experimental studies to assert that many of these spatial behaviors depend on to a great extent visual perception. In cases where an object or a place to reach is visible, the movement or trajectory is directly guided by the visual perception of the goal or of conspicuous landmarks associated with it. In many circumstances, however, spatial behavior takes place in larger environments where the goal is not visible. In that case, it is necessary that spatial knowledge takes the form of a representation. The latter may simply consist of remembering a specific route to follow, but this simple means to achieve accurate trajectories lacks adaptive properties (O'Keefe & Nadel, 1978). The most adequate form of spatial representation is that of the topography of the environment beyond perceptual reach. This representation is acquired either by one using symbolic supports (such as reading a map) or progressively constructing one's internal map on the basis of experience (as when one frequently goes shopping in the district in which one resides, e.g.).

The continuity of depression in clinical and nonclinical samples.

Abstract: Historically, depression researchers have examined continuity in terms of whether the symptoms and characteristics of mild, moderate, and severe depression differ in degree along a continuum (i.e., a quantitative difference) or in kind (i.e., qualitative difference). The authors propose a differentiated framework that distinguishes 4 direct tests of continuity (i.e., phenomenological, typological, etiological, and psychometric continuity). They use this framework to suggest that most evidence is consistent with the continuity hypothesis. Moreover, they maintain that the findings of future research can be incorporated into a 2-factor model of depression that allows for both continuities and discontinuities.

The role of immaturity in human development.

Abstract: The possibility that infants' and young children's immature behaviors and cognitions are sometimes adaptive is explored and interpreted in terms of evolutionary theory. It is argued that developmental immaturity had an adaptive role in evolution and continues to have an adaptive role in human development. The role of developmental retardation in human evolution is discussed, followed by an examination of the relation between humans' extended childhood and brain plasticity. Behavioral neoteny, as exemplified by play, is examined, as are some potentially adaptive aspects of infants' perception and cognition that limit the amount of information they can process. Aspects of immature cognition during early childhood that may have some contemporaneous adaptive value are also discussed. It is proposed that viewing immaturity as sometimes adaptive to the developing child alters how children and their development are viewed. Nature wants children to be children before they are men. If we deliberately depart from this order, we shall get premature fruits which are neither ripe nor well flavored and which soon decay. We shall have youthful sages and grown up children. Childhood has ways of seeing, thinking, and feeling, peculiar to itself; nothing can be more foolish than to substitute our ways for them. —Jean Jacques Rousseau

Family risk factors for child and adolescent suicidal behavior

Abstract: In this review, the author evaluates the empirical support for the claims that various aspects of family dysfunction are risk factors for completed suicide or suicidal symptoms in childhood or adolescence. There is consistent evidence that a history of physical or sexual abuse is a risk factor and some evidence for other risk factors, including poor family or parent-child communication, loss of caregiver to separation or death, and psychopathology in first-degree relatives. However, the researchers of the vast majority of studies did not attend to whether the putative risk factors preceded the development of suicidal symptoms; thus, most of the claims regarding family risk factors are not justified by their research designs and findings.

Mild head injury in children and adolescents: a review of studies (1970-1995).

Abstract: In this article, the authors provide a comprehensive review of the research of mild head injury in children and adolescents from 1970 to 1995 Because of marked variability in methodologies across studies, a preliminary box-score tally was computed, without regard to studies' scientific or methodological merit These results revealed 13 adverse, 18 null, and 9 indeterminate findings related to neuropsychological, academic, or psychosocial outcome When studies were classified based on methodological merit, the stronger studies were generally associated with null outcomes across domains However, a few of the less stronger neuropsychological studies (5 of 40) reported subthreshold and transitory alterations during the early postinjury period At the present time, cautious acceptance of the null hypothesis is recommended until more definitive studies are conducted that address the problems raised in this review Language: en

Proper analysis of the accuracy of group judgments

Abstract: Modern societies rely heavily on groups to make important economic and political decisions. However, a review of research on group processes shows that progress has been slow in the delineation of the conditions that promote or impede efficient, accurate group judgments. One reason for the slow progress is that research methods and data analysis in this area are varied, difficult to compare, and often substandard. In this review, the authors summarize alternate methods of analysis and provide detailed illustrations of the best methods for assessing and analyzing group judgment accuracy

Biases in the quantitative measurement of values for public decisions

Abstract: Measurement of personal values in terms of money or utility can promote efficient public decisions about environmental and risk regulation, health care, and so forth. Current measures are subject to several biases. Quantitative judgments of value are often based on a concept of importance that ignores the quantity of the good being valued. They are sensitive to irrelevant factors, such as cost of the good (vs. its benefit) and whether it has been reduced by human action or nature. Some judgments are based on moral opinions about actions rather than on the value of consequences. Some of these problems seem solvable by methods that remove irrelevant information or force attention to relevant information. Other problems are less tractable. Their solution should be a high priority for research.

Imagery in human classical conditioning.

Abstract: Many clinical strategies use patients' imagery to explore and treat phobic and posttrauma reactions, however little attention has been paid to the underlying assumption that imagery of relevant stimuli may help maintain conditioned behavior. In this article, the authors examine the premise that mental images can potentiate and substitute for physical stimuli in human classical conditioning. The authors review empirical evidence to detail the role of images of conditioned stimuli (CS) and unconditioned stimuli (US) during pre-exposure to stimuli, the actual pairing of the CS and US, and extinction when the CS is presented alone. The evidence suggests that mental imagery can facilitate or diminish the outcome of classical conditioning in humans and, more tentatively, that mental images can substitute for actual US and CS in autonomic conditioning. They argue that researchers should explore the role of mental imagery in conditioning through the use of advances in the measurement of imagery. Finally, they analyze anxiety and trauma reactions as examples of how applied areas can be used to explore and benefit from developments in this area.

"Stupidity or worms": do intestinal worms impair mental performance?

Abstract: The title of a 1930s article asked the question, "Stupidity or Hookworm?" In this article, the authors discuss research that attempts to answer the question of whether intestinal worms--namely, hookworm, whipworm, and roundworm--harm the mental performance of their hosts. After introducing the biology and epidemiology of intestinal worms, the authors present the historical background to the problem. They review research from the 1910s through the 1990s; there is evidence that high intensities of worms can affect mental performance, but not all dewormed children show improved performance. They discuss the mechanisms of how worms might affect the mind.

Is Alcohol a Cofactor of HIV and AIDS? Evidence From Immunological and Behavioral Studies

Abstract: The authors aim to critically examine empirical research on the effects of alcohol on HIV and AIDS from the immunological and behavioral fields. In vitro immunological studies demonstrate that social drinking increases the susceptibility of human cells to HIV infection. Animal studies show that acute and chronic alcohol ingestion increases rate of progression from retrovirus to clinical illness. In humans with HIV, no experimental evidence shows that alcohol is a cofactor of AIDS. Findings from behavioral studies show that a link between social drinking and risk of HIV is weak. No experimental evidence demonstrates that chronic drinking influences rate and course of disease progression to AIDS in humans who are HIV+. It is premature to promote the role of alcohol as a cofactor in HIV and AIDS.

Cooperation and competition in peaceful societies

Abstract: Most of the world's nonviolent societies base their peaceful worldviews on cooperation and an opposition to competition. Although they have nurturant, affiliative societies, many raise their children to be hesitant and fearful about the intentions of others so that they will internalize nonviolent values and never take their peacefulness, or that of others, for granted. The children in these societies lack competitive games; although they are loved as babies, by the time they are 2 or 3 years old, they are made to feel no more important than others. These societies devalue achievement because it leads to competition and aggressiveness, which leads to violence they feel. Their rituals reinforce their cooperative, harmonious beliefs and behaviors. They have internalized their peaceful, cooperative values so that their psychological structures accord with their beliefs in nonviolence.
