TL;DR: Though not directly related to reported exposure to bullying behaviors, generalized self-efficacy seemed to act as a moderator of the relationship between exposure tobullying behaviors and psychological health complaints.
Abstract: The aim of this study was to investigate the relationships between exposure to behaviors identified as workplace bullying and self-report measurements of psychological and psychosomatic health complaints. Secondly, we investigated whether these relationships were mediated by the state negative affectivity of the victim. Thirdly, we investigated the extent to which generalized self-efficacy moderated the relationships between exposure to bullying behaviors and health complaints. Two hundred and twenty-four white- and blue-collar employees from a Danish manufacturing company participated in the study. Exposure to bullying behaviors was associated with an increase in psychological health complaints, increased levels of psychosomatic complaints and an elevated level of state negative affectivity. Whereas bullying by itself accounted for 27% of the variance in psychological health complaints and 10% of the variance in psychosomatic complaints, the results pointed to state negative affectivity as a partial mediator of the relationships between exposure to bullying behaviors and both measures of self-reported health. Though not directly related to reported exposure to bullying behaviors, generalized self-efficacy seemed to act as a moderator of the relationship between exposure to bullying behaviors and psychological health complaints.

TL;DR: Differences between subjects high and low in emotional empathy appeared to be related to differences in automatic somatic reactions to facial stimuli rather than to Differences in their conscious interpretation of the emotional situation.
Abstract: The hypotheses of this investigation were derived by conceiving of automatic mimicking as a component of emotional empathy. Differences between subjects high and low in emotional empathy were investigated. The parameters compared were facial mimicry reactions, as represented by electromyographic (EMG) activity when subjects were exposed to pictures of angry or happy faces, and the degree of correspondence between subjects' facial EMG reactions and their self-reported feelings. The comparisons were made at different stimulus exposure times in order to elicit reactions at different levels of information processing. The high-empathy subjects were found to have a higher degree of mimicking behavior than the low-empathy subjects, a difference that emerged at short exposure times (17-40 ms) that represented automatic reactions. The low-empathy subjects tended already at short exposure times (17-40 ms) to show inverse zygomaticus muscle reactions, namely "smiling" when exposed to an angry face. The high-empathy group was characterized by a significantly higher correspondence between facial expressions and self-reported feelings. No differences were found between the high- and low-empathy subjects in their verbally reported feelings when presented a happy or an angry face. Thus, the differences between the groups in emotional empathy appeared to be related to differences in automatic somatic reactions to facial stimuli rather than to differences in their conscious interpretation of the emotional situation.

TL;DR: The present study of the cognitive functions in depression was part of an extensive investigation, including neuropsychological testing, psychiatric examination, and neuroimaging, confirming the current notion that depressed patients suffer from wide-spread cognitive impairments.
Abstract: Major depression is a mood disorder that is often accompanied by the impairment of cognitive functions. Although suggestive, the large range of existing neuropsychological, neuropsychiatric, and, lately, neuroimaging investigations have not yet given a consistent picture of the psychological and biological disturbances involved in this psychiatric disorder. The present study of the cognitive functions in depression was part of an extensive investigation, including neuropsychological testing, psychiatric examination, and neuroimaging. A representative sample of 40 severely depressed hospitalized patients and a group of 49 closely matched control subjects were tested with an extensive neuropsychological test battery. Results, corrected for various confounding factors, confirmed the current notion that depressed patients suffer from wide-spread cognitive impairments. The group analysis did not allow any hypothesis on a possible pattern to the dysfunctions, but heterogeneity in the test performances calls for further analysis of the data in patient subgroups in relation to neuroimaging results.

TL;DR: A person-oriented approach was applied in order to analyze children's value patterns with respect to learning skills, self-concept, and social intelligence, and how these value patterns are related to bully-victim problems.
Abstract: Learning skills, social intelligence, and self-concept were related to each other and to bully-victim problems among fifth-grade children (79 boys and 62 girls, aged 11-12 years). In addition to exploring connections between single variables, a person-oriented approach was applied in order to analyze children's value patterns with respect to learning skills, self-concept, and social intelligence, and how these value patterns are related to bully-victim problems. Social intelligence was found to be positively correlated with learning skills, but negatively related to victimization. Bullying was positively correlated with self-concept scores. However, this was true only of boys. According to cross-tabulations, there were significantly more bullies among children with learning difficulties (LD) than would have been expected by chance. Victimization, on the other hand, was not related to LD. LD children's proposed victim status was in some degree supported by cluster analysis: a group of LD children emerged, who not only scored high on bullying, but also tended to be victimized by others. In addition, two groups of bullies appeared: one whose members could be interpreted as socially unskilled and another as socially skilled. This finding is in line with recent theoretical reasoning, which calls into question the idea of bullies as a unified group, lacking in social skills.

TL;DR: It is concluded that sensitization may be organized at different levels, both in the organism and in the larger living system within which the organism is subsumed.
Abstract: Sensitization is conceptually related to cognitive bias in experimental psychopathology, and they share the basic mechanism of neuronal sensitization. Every strongly relevant individual concern, like fears, can yield cognitive bias or "cognitive-emotional sensitization". It might also be present for bodily and environmental information related to illness, and could be an etiological factor in medically unexplained complaints. Physiological and cognitive sensitization are theoretically compared. There is evidence for cognitive-emotional sensitization in some medically unexplained somatic complaints, and negative affect is suggested as a catalyst. Prolonged cognitive-emotional sensitization ("perseverative negative cognition" or worry, rumination) might even have demonstrable somatic pathological effects. It is concluded that sensitization may be organized at different levels, both in the organism and in the larger living system within which the organism is subsumed. This view might not only help to clarify medically unexplained pain syndromes, but virtually every subjective complaint, both with and without recognized physiopathology.

TL;DR: The studies indicate that children raised by lesbian women do not experience adverse outcomes compared with other children, and the same holds for children raise by gay men, but more studies should be done.
Abstract: Twenty-three empirical studies published between 1978 and 2000 on nonclinical children raised by lesbian mothers or gay fathers were reviewed (one Belgian/Dutch, one Danish, three British, and 18 North American). Twenty reported on offspring of lesbian mothers, and three on offspring of gay fathers. The studies encompassed a total of 615 offspring (age range 1.5-44 years) of lesbian mothers or gay fathers and 387 controls, who were assessed by psychological tests, questionnaires or interviews. Seven types of outcomes were found to be typical: emotional functioning, sexual preference, stigmatization, gender role behavior, behavioral adjustment, gender identity, and cognitive functioning. Children raised by lesbian mothers or gay fathers did not systematically differ from other children on any of the outcomes. The studies indicate that children raised by lesbian women do not experience adverse outcomes compared with other children. The same holds for children raised by gay men, but more studies should be done. Language: en

TL;DR: The study findings indicate that empathy is hierarchically organized, with one general dimension at the apex, and that the general dimension constitutes an integrated entirety, with its main emphasis on emotional reactivity by also involving cognitive processes.
Abstract: The purpose of the present study was to examine the structure of empathy using a hierarchical approach, and to compare the dimensions of empathy with measures of social functioning, in order to contribute to the understanding of the nature of empathy. The dimensionality of the Interpersonal Reactivity Index, which comprises four subscales (empathic concern, perspective taking, fantasy and personal distress) was examined using confirmatory factor analysis. Relations with the Social Skills Inventory were also investigated. A sample of 127 applicants for places on nursing and social work undergraduate programs participated in the study. The study findings indicate that empathy is hierarchically organized, with one general dimension at the apex. The general factor is identical to empathic concern and this dimension overlaps to a great extent with perspective taking and fantasy. The findings also indicate that the general dimension constitutes an integrated entirety, with its main emphasis on emotional reactivity by also involving cognitive processes.

TL;DR: The results showed that the adjective scale ratings could be aggregated as reliable measures of the independent valence and activation dimensions proposed in the affect circumplex, and that the aggregated measures discriminated mood differences within and between individuals.
Abstract: Three studies were conducted with the aim of developing a new Swedish self-report measure of core affect (the Swedish Core Affect Scale or SCAS). In Study 1,122 participants rated their current mood on 24 unipolar adjective scales. A revised set of 12 bipolar adjective scales was evaluated in Study 2 employing 96 participants who rated their current mood before and after a mood-inducing naturally occurring event. A slightly revised set of adjective scales was used in Study 3, in which another 96 participants rated several induced moods. The results showed that the adjective scale ratings could be aggregated as reliable measures of the independent valence and activation dimensions proposed in the affect circumplex, and that the aggregated measures discriminated mood differences within and between individuals.

TL;DR: It is shown that inhibition is important for adaptive behavior across a number of levels of system functioning and both central and peripheral inhibitory processes may be linked by a network of neural structures that guide the organism from one state of relative stability to another.
Abstract: There is increasing evidence that the behavior of living systems can be conceptualized as a self-organizing dynamical system. Moreover, evidence suggests that inhibitory processes give these systems the flexibility that is necessary for efficient functioning in the face of changing environmental demands. The process of sensitization can be conceived as a breakdown of inhibitory neural processes that can lead to maladaptive, perseverative behavior. In this paper we describe a model of inhibition and sensitization from a dynamical systems perspective. We show that inhibition is important for adaptive behavior across a number of levels of system functioning. Using our work on attention, emotion, and anxiety disorders we show the importance of both central - for example gamma-aminobutyric acid (GABA)-ergic - and peripheral - for example heart rate variability (HRV) - inhibitory processes and how they may be linked by a network of neural structures that guide the organism from one state of relative stability to another.

TL;DR: The psychometric qualities of a scale intended to measure adolescents' risk-taking attitudes to driving were satisfactory, and the attitude dimensions were significantly correlated with self-reported driving behavior, as well as accident frequency.
Abstract: Adolescents are proportionately more frequently involved in traffic accidents than are other age groups. A strategy for promoting road safety is to change the attitudes likely to influence driving behavior. However, the lack of valid and reliable instruments to measure risk-taking attitudes makes it difficult to evaluate the effects of measures aimed at changing attitudes among young drivers and their passengers. The present study tested the psychometric qualities of a scale intended to measure adolescents' risk-taking attitudes to driving. The results are based on a self-completion questionnaire survey carried out among 3,942 adolescents and young adults, aged 16-23 years, in Norway in 1998/1999. Using both exploratory and confirmatory factor analyses, 11 dimensions of risk-taking attitudes were identified. Parametric as well as nonparametric methods were applied to test the homogeneity of items within each attitude dimension. The reliability and validity of the dimensions were satisfactory. The attitude dimensions were significantly correlated with self-reported driving behavior, as well as accident frequency. The application of the new measurement instrument in studies aimed at evaluating safety campaigns is discussed. Language: en

TL;DR: It is argued that, in the long run, pain-related negative affect has sensitizing and disabling effects and worrying about pain and avoidance of pain-inducing activities may increase negative affect, ypervigilance, and functional disability.
Abstract: Pain usually has a strong negative affective component, which is believed to modulate pain perception. After reviewing theories on the link between negative affect and pain, mechanisms are discussed by which negative affect may either increase or inhibit pain. Possible pain-inhibiting mechanisms are endogenous opioid release, blood pressure reactivity, and distraction of attention; possible pain-increasing mechanisms are autonomic and muscular reactivity, misattribution of arousal, hypervigilance to pain, worrying, and avoidance behavior. It is emphasized that each of these mechanisms can be very adaptive in acute pain situations to prevent injury and promote recovery. In chronic pain, however, ongoing physiological arousal and hypervigilance to pain, induced or magnified by negative affect, may cause sensitization to pain. Furthermore, worrying about pain and avoidance of pain-inducing activities may increase negative affect, ypervigilance, and functional disability. It is argued that, in the long run, pain-related negative affect has sensitizing and disabling effects.
TL;DR: The combination of cognitive psychology and neurophysiology offers a model for somatic pathology, and, perhaps more important, also for the understanding of subjective complaints and illness.
Abstract: Why is it that some of us have more pain, more fatigue, and more gastrointestinal trouble than others? Is it possible that there are brain mechanisms and psychological mechanisms that make some people sensitized to specific complaints? In this concluding paper we review the historical and theoretical background, discuss the evidence and theoretical positions in the contributions, and draw some conclusions. Traditional psychosomatic models had less predictive value and less therapeutic importance than what was hoped for. The main problem with these models was the lack of a pathophysiological explanation for why psychological problems could be related to somatic disease. Sustained arousal or "allostatic load" offers more plausible and acceptable mechanisms for pathology, and, to some extent, for sensitization and illness. The combination of cognitive psychology and neurophysiology offers a model for somatic pathology, and, perhaps more important, also for the understanding of subjective complaints and illness.
TL;DR: A variety of subjective illnesses with few or no objective findings have appeared at regular intervals as epidemics in our society under different labels as discussed by the authors, and the subjective illnesses are among the most frequent reason for encounters with general practitioners, and one of the major causes for sickness absence.
Abstract: A variety of subjective illnesses with few or no objective findings have appeared at regular intervals as epidemics in our society under different labels. There are few or no objective findings that might explain the "disease" or the complaints go beyond what is regarded as "reasonable" by the physician. Muscle pain and other types of subjective health complaints are among the most frequent reason for encounters with general practitioners, and one of the major causes for sickness absence. The prevalence of subjective health complaints is very high, with at least 75% of the population reporting one or more subjective health complaints the past 30 days. From a statistical point of view, it is "normal" to have complaints. It is when they become intolerable that assistance is required. The difficult thing is that this threshold is individual and subjective. The psychiatric definitions of these complaints, therefore, refer only to the tip of an iceberg.
TL;DR: The present study investigated the temporal dynamics of auditory sensory memory in newborns as reflected by the mismatch negativity (MMN), a preattentive electric change-detection response, implying that the time span of auditory memory is considerably shorter in neonates than in adults and 8-12-year-old children.
Abstract: The present study investigated the temporal dynamics of auditory sensory memory in newborns as reflected by the mismatch negativity (MMN), a preattentive electric change-detection response. MMN was obtained from 24 full-term healthy newborns who were either awake or asleep (quiet or active sleep) during the experiments. Stimuli were 1,000 Hz tones (standards) that were occasionally replaced by 1,100 Hz tones (deviants). The constant stimulus onset asynchrony (SOA) was, in separate blocks, either 450, 800, or 1,500 ms. A prominent MMN was obtained at the 800 ms SOA in all three sleep or waking states, whereas no MMN occurred at 450 and 1,500 ms SOAs. In view of the fact that in adults MMN is elicited even with a 10s SOA, these results imply that the time span of auditory memory is considerably shorter in neonates than in adults and 8-12-year-old children.
TL;DR: A series of experiments, using inhalations of air enriched with CO2 and external (odors) or internal (mental images) stimuli as cues, is discussed to show that subjective health complaints may occur upon presenting the cue alone.
Abstract: Symptom episodes often show a spatio-temporal structure, that is, they occur in a specific context for a certain duration. Repeated experiences may therefore be construed as associative learning trials, in which context elements are turned into predictive cues, triggering anticipatory processes conducive to subjective health complaints. A series of experiments, using inhalations of air enriched with CO2 and external (odors) or internal (mental images) stimuli as cues, is discussed to show that subjective health complaints may occur upon presenting the cue alone. Learned symptoms may be unrelated to bodily responses and easily generalize to new related cues. Better learning occurs to cues with a negative affective valence and in participants scoring high for negative affectivity. Our findings are relevant to the understanding of medically unexplained ("functional") syndromes and the poor relationship between objective and subjective health indicators in general.
TL;DR: The results showed that the single-exposure group revealed a decrease in trauma specific stress reactions from three weeks to four months, with a persistent reduction at 12-month follow-up, while the repeated-ex exposure group showed an increase in symptom reporting over the 12- month period.
Abstract: The present study investigated the effects of multiple trauma exposure and coping style on post-traumatic stress symptoms and quality of life. It was hypothesized that sensitization would occur in subjects repeatedly exposed to life-threatening situations (study 1), and different coping styles would act as a resilience or facilitating factor in symptom development (study 2). The results showed that the single-exposure group revealed a decrease in trauma specific stress reactions from three weeks to four months, with a persistent reduction at 12-month follow-up, while the repeated-exposure group showed an increase in symptom reporting over the 12-month period. The same pattern emerged for perceived quality of life-measured by the General Health Questionnaire (GHQ-30). The second study revealed a correlation between scores on avoidant-focused coping style and the Impact of Event Scale-avoidance dimension, Post-traumatic Symptom Scale and GHQ-30. Furthermore, only subjects with a dominant coping style of emotion-focused or task-focused coping showed a reduction in trauma-specific symptom scores over time. Language: en
TL;DR: A model is proposed that implies that planning evoked by the formation of an implementation intention is related to behavioral intention and perceived behavioral control, whereas in accordance with the theory of planned behavior, behavioral intention isrelated to attitude and perceived Behavioral control.
Abstract: A model is proposed that implies that planning evoked by the formation of an implementation intention is related to behavioral intention and perceived behavioral control, whereas in accordance with the theory of planned behavior, behavioral intention is related to attitude and perceived behavioral control. Measures of attitude toward the behavior, perceived behavioral control, behavioral intention, and planning were constructed from 192 undergraduates' ratings of descriptions of two fictitious situations in which a target behavior was varied with respect to benefit and actual behavioral control. Structural equation modeling yielded an acceptable fit of the proposed model.
TL;DR: Finding to what extent theme and professional involvement influence interactions in discussion forums might guide further professional involvement in online group settings and the design of appropriate online environments is searched for.
Abstract: The present study examined interactions on three Norwegian online discussion forums, and attempted to identify differences in interactions and plausible outcomes of thematically dissimilar forums. Four categories were applied to the forums in order to distinguish potentially constructive and destructive uses. Interaction along the constructive-destructive dimension was contingent upon the themes discussed, as well as the level and nature of professional involvement. Interaction adhering to a destructive dimension was identified only in relation to the forum for eating disorders. Discovering to what extent theme and professional involvement influence interactions in discussion forums might guide further professional involvement in online group settings and the design of appropriate online environments.
TL;DR: Key aspects of synaptic plasticity known from the brain and in the spinal cord are summarized and related changes in spinal nociceptive neurons are described and discussed based on results from the own laboratory.
Abstract: Besides transmitting and processing, neurons may also store information for prolonged periods of time (e.g. by use-dependent change in synaptic strength). In 1966 long-term potentiation (LTP) of synaptic transmission was discovered in the hippocampus, an area implicated in learning and memory. Recent studies show that similar mechanisms apply to pain pathways, at least in the spinal cord, and may account for some forms of clinical problems like hyperalgesia, allodynia, and deafferentation pain states, such as phantom pain. In this review, we briefly summarize key aspects of synaptic plasticity known from the brain and in the spinal cord. Then we describe and discuss related changes in spinal nociceptive neurons based on results from our own laboratory.
TL;DR: The conclusion is that age and education promote the extension of adolescents' identity horizons, provided that their spatial integration is solid enough to absorb the downward effect of a new identity context.
Abstract: A sense of being the same person through time and social contexts is a central characteristic of identity formation. The spatial integration of identity was investigated in three groups of high school students differing in age and/or educational level. The 294 adolescents chose and ranked personally revealing identity contexts, described their general and context-specific identities, and indicated their subjective sense of well-being. With increasing age and educational level adolescents chose an increasing number of identity contexts. Context-specific identities were found on average to be closely interwoven. There was a positive linear relationship between spatial integration and subjective well-being. The conclusion is that age and education promote the extension of adolescents' identity horizons, provided that their spatial integration is solid enough to absorb the downward effect of a new identity context. A comparison between spatial integration and two measures of exploration and commitment showed that spatial integration is a relatively powerful measure of adolescent identity.
TL;DR: There are ways in which these non-associative and associative processes may enhance associative learning of workplace-avoidance behaviors that are exceptionally persistent - even in the absence of further somatic discomfort.
Abstract: This paper reviews those features of non-associative and associative forms of learning, as elaborated in the experimental literature, that might contribute to experienced and reported discomfort in the workplace. Emphasis is given to sensitization, while noting that some models of habituation (e.g. the opponent process model) also produce sensitization-like effects as a by-product that could contribute to persistent complaints. Also noted are ways in which these non-associative processes may enhance associative learning of workplace-avoidance behaviors that are exceptionally persistent - even in the absence of further somatic discomfort.
TL;DR: The data support the reliability of the Francis Scale of Attitude toward Christianity and commend it for further validation studies and for wider general use among young people in Norway.
Abstract: This paper reviews the development of the Francis Scale of Attitude toward Christianity and then examines the psychometric properties of the Norwegian translation of this instrument among a sample of 479 young people between the ages of 11 and 18 years attending secondary school. The data support the reliability of this instrument and commend it for further validation studies and for wider general use among young people in Norway.
TL;DR: Both subjective and autonomic responses indicated that anxiety was successfully induced in participants exposed to the anxiety condition, and gender differences were found for pain threshold in the anxiety group with females showing significantly higher pain thresholds than males.
Abstract: The aims of the present study were to investigate the influence of anxiety on pain perception and to test whether gender differences in pain perception are anxiety dependent. Sixty male and female university students exposed to situation-evoked anxiety or a control procedure were measured for their pain threshold, tolerance, and perceived intensity during a cold pressor test. Both subjective and autonomic responses indicated that anxiety was successfully induced in participants exposed to the anxiety condition. Increased situational anxiety had no significant effect on pain threshold or pain tolerance. Significant increases in pain intensity were found for the anxiety group. Levels of anxiety, however, did not correlate with this increased intensity, raising doubt as to the role of anxiety in producing this effect. No gender differences were found for pain tolerance or pain intensity. Gender differences were found for pain threshold in the anxiety group with, contrary to past findings, females showing significantly higher pain thresholds than males. The results are discussed in the light of related studies.
TL;DR: There is considerable overlap of non-specific symptoms like fatigue, headache, abdominal discomfort, muscle pain, and sleep disturbance in patients with different functional disorders, in this article exemplified by FD, fibromyalgia, and chronic fatigue syndrome.
Abstract: Functional dysepsia (FD) is defined as persistent or recurrent pain or discomfort centered in the upper abdomen without evidence of organic disease likely to explain the symptoms. Visceral hypersensitivity, motor dysfunction, and impaired gastric accommodation are found in some patients with FD, and psychological factors like chronic stress, attention and perception bias are also likely to play a part in the symptom formation. There is considerable overlap of non-specific symptoms like fatigue, headache, abdominal discomfort, muscle pain, and sleep disturbance in patients with different functional disorders, in this article exemplified by FD, fibromyalgia, and chronic fatigue syndrome. This overlap of symptoms indicates a common underlying sensitization process, leading to somatization.
TL;DR: It is suggested that a transactional model, where both potential risk factors and protective factors are considered, should replace the traditional teratology model in this field.
Abstract: This paper discusses several factors affecting the development of children prenatally exposed to drugs. In the "first generation" of research in this field a main factor model of disease formed the basis for a belief in the feasibility of detecting the direct pharmacological or teratogenic effects of drug exposure on long-term child development. However, the clustering of confounding variables has constituted a major problem in identifying these effects. In the last few years a "second generation" of research in this field has emerged, and investigators have moved beyond simple main-effect models. The importance of controlling for confounding variables has been underscored. However, prenatal substance exposure is still often studied within a teratology model where the main goal is the search for unique effects of a specific drug or substance. Based on this review it is suggested that an appropriate model for understanding the development of drug-exposed children cannot be based on a main-effect perspective. Rather, such a model must evolve from a contextual perspective, and it is suggested that a transactional model, where both potential risk factors and protective factors are considered, should replace the traditional teratology model in this field.
TL;DR: Overall, elderly insomniacs scored higher on measures of worry compared with the other groups, followed by measures of somatization, obsessive-compulsion and depression, and it was concluded that excessive worrying was the most characteristic feature of elderly INSOMniacs.
Abstract: Sixty insomniacs, aged 60 years or over, fulfilling the DSM-IV criteria for primary insomnia, completed a set of questionnaires measuring psychological distress. These included the Sleep Impairment Index (SIM), the Symptom Check List 90-Revised (SCL-90-R), the Penn State Worry Questionnaire (PSWQ), the Toronto Alexithymia Scale-20 (TAS-20) and the Elders Life Stress Inventory (ELSI). The insomniacs were compared on these measures with two contrast groups, one of elderly good sleepers and one an elderly community sample. As norms were developed for the SCL-90-R and PSWQ, insomniacs were also contrasted with the norm groups on these measures. In general, the results indicated a higher level of psychological distress among insomniacs than among the good sleepers, while there were negligible differences between insomniacs and the community sample on most measures. Overall, elderly insomniacs scored higher on measures of worry compared with the other groups, followed by measures of somatization, obsessive-compulsion and depression. It is concluded that excessive worrying was the most characteristic feature of elderly insomniacs. Language: en
TL;DR: There is no evidence that severe physical disease in childhood is associated with later unexplained symptoms, but common childhood unexplained symptoms are predictors of symptoms in adulthood.
Abstract: Clinical experience suggests that a high proportion of patients with medically unexplained symptoms or somatoform disorders give histories of adverse childhood experiences. Previous work has reported that both personal and family experience of illness may be associated with later unexplained symptoms in the individual. Most of this research is subject to recall bias. This review explores data from the UK Medical Research Council National Survey of Health and Development, a population-based birth cohort study. The main finding of this work is that childhood experience of illness in parents is an independent risk factor for later unexplained symptoms. Personal experience of illness has a more complicated relationship. There is no evidence that severe physical disease in childhood is associated with later unexplained symptoms, but common childhood unexplained symptoms are predictors of symptoms in adulthood.
TL;DR: The main finding was that the medical students performed better than the psychology students for all figure orientation subtests and for all arm positions.
Abstract: The present study investigated right left discrimination, with a paper-and-pen test with cartoon figures. The test consisted of line drawings of a person with no, one, or both arms crossing the vertical axis of the body in the figure. The subjects' task was to mark with a pencil, as fast as possible, which was the right or left hand in the figure. The line drawings were viewed from the back, from the front, or randomly alternating between the back and front views. Two studies were conducted. The first consisted of 393 adults: 153 males and 240 females; 338 right-handers and 55 left-handers. The results showed that the males performed better than the females. The left-handers and the right-handers performed equally well. However, the left-handed males performed better than the right-handed males. There was no difference in performance between the right-handed and the left-handed females. The second study consisted of 175 right-handed college students: 63 psychology students. 54 medical students, and 58 law students. The main finding was that the medical students performed better than the psychology students for all figure orientation subtests and for all arm positions. In comparison with the law students, the medical students performed at the same level on the back view subtest, but they performed better on the front view subtest and on two out of three arm positions on the alternating view subtest.
TL;DR: The children with Down syndrome had less attentional focusing and expressed less inhibitory control and less sadness than the normally developing children and the temperament structures in the Norwegian samples were very similar to those reported in earlier studies, conducted in China and the US.
Abstract: Parents of three groups of children completed the Children's Behavior Questionnaire (CBQ). Participants were children with Down syndrome aged 4-11 years (n = 55), prematurely born children aged 5 years (n = 97), and a group of normally developing kindergarten children 5-7 years of age (n = 91). Mean levels and factor structures on the CBQ were compared between the three groups. The children with Down syndrome had less attentional focusing and expressed less inhibitory control and less sadness than the normally developing children. There were also group differences in temperament structures, especially a clearer emotional factor of "surgency" among the children with Down syndrome. The only significant difference in mean temperament scores between the premature children and the control group was that the former evinced less attentional focussing. The temperament structures in the Norwegian samples were very similar to those reported in earlier studies, conducted in China and the US.
TL;DR: An experiment in which naming times in Icelandic for 175 stimuli from the Snodgrass and Vanderwart picture set were determined showed that objective age of acquisition was the strongest predictor of naming time, with familiarity and name agreement also showing a significant effect.
Abstract: Numerous studies have found that word frequency has a significant effect on the time it takes to name an object or read a word. Recently, claims have been made that this frequency effect is perhaps more correctly interpreted as an age of acquisition effect. This paper reports an experiment in which naming times in Icelandic for 175 stimuli from the Snodgrass and Vanderwart picture set were determined. A multiple regression analysis of naming times against a number of independent factors showed that objective age of acquisition was the strongest predictor of naming time, with familiarity and name agreement also showing a significant effect. The effect of word frequency was, however, not significant. Possible reasons for this are discussed.
