Favourite objects of autistic children

Favourite objects (FOs) of autistic children were compared with the FOs of healthy preschool and school children as well as mentally handicapped children. Three clusters of objects were obtained for normal children (comprising primary transitional objects and their forerunners, secondary transitional objects, and non-cuddly toys). When autistic children and mentally handicapped children were included, a fourth cluster of deviant objects was found. Frequency distributions of the two handicapped groups in the clusters were similar. Similarities between the two handicapped groups were also found within each cluster. The occurrence of secondary transitional objects was rare in the handicapped groups. The characteristics of "autistic" FOs reported in earlier case studies (e.g. being hard, often having an exciting effect, not being used in their adequate functions) were typical only of objects in the fourth cluster.     

Sex stereotypes and implicit personality theory: Toward a cognitive—Social psychological conceptualization

Progress in understanding sex stereotypes has been impeded by the failure of researchers to address two critical conceptual questions: What is a sex stereotype? How do sex stereotypes function in social cognition and behavior? As a step toward answering the first question, the meaning of the term “sex stereotype” was considered. On the basis of points of agreement among extant conceptual definitions of the construct “stereotype” (in both the female-male and ethnic relations literatures), a generic definition of “sex stereotypes” is proposed: the structured sets of beliefs about the personal attributes of women and of men. In order to relate sex stereotypes more closely to research and theory on “normal” psychological processes, this basic definition is recast in terms of the person perception construct, “implicit personality theory”: the structured sets of inferential relations that link personal attributes to the social categories female and male. Two studies are presented to illustrate the utility of this translation. The remainder of the article addresses the second question. Here we offer preliminary ideas regarding a more general cognitive—social psychological framework for the study of sex stereotypes. Stereotype and stereotyping are distinguished, and each is discussed in light of relevant research in cognitive and social psychology.     

"Unlearning" automatic biases: the malleability of implicit prejudice and stereotypes.

The present research suggests that automatic and controlled intergroup biases can be modified through diversity education. In 2 experiments, students enrolled in a prejudice and conflict seminar showed significantly reduced implicit and explicit anti-Black biases, compared with control students. The authors explored correlates of prejudice and stereotype reduction. In each experiment, seminar students' implicit and explicit change scores positively covaried with factors suggestive of affective and cognitive processes, respectively. The findings show the malleability of implicit prejudice and stereotypes and suggest that these may effectively be changed through affective processes.     

Sex stereotypes and implicit personality theory. I. A personality description approach to the assessment of sex stereotypes

It was proposed that sex stereotypes be phrased in terms of the person perception construct, “implicit personality theory,” as the structured sets of inferential relations that link personal attributes to the social categories female and male. The utility of this formulation was assessed by having 31 college students use a set of 66 personality traits to describe other people. A measure of trait co-occurrence was derived from these data and was used as input to Kruskal's multidimensional scaling program. A two-dimensional configuration was interpreted in terms of two orthogonal properties, Social Desirability and Potency. An Indirect Female-Male property (based on the proportion of times each trait was used to describe a male) was strongly related to the configuration and was closely aligned with the Potency vector. Thus, stereotypes of females and males were associated with the Potency dimension of person perception, with females seen as “soft” and males as “hard.” The directly rated sex property Male-Female was also located near the Potency vector, but was not strongly related to the configuration. This lack of fit may have been due to social desirability responding. The results support the utility of formulating sex stereotypes in terms of implicit personality theory and suggest the need to distinguish direct and indirect assessments of stereotypes.     

The ontogeny of defensive reactions in the rat: Influence of the monoamine transmission systems

The effects of neonatal treatment of rats with the neurotoxins 5,7-dihydroxytryptamine and 6-hydroxydopamine on the ontogeny of the ultra sound vocalization and the immobility response were studied. The 5,7-dihydroxytryptamine treated rats showed reduced strength of both reactions indicating involvement of the serotonin system in their ontogeny. This hypothesis was supported by experiments with depletion of serotonin by para-chlorophenylalanine followed by replenishment with 5-hydroxytryptophan. The 6-hydroxydopamine treated rats showed normal defensive reactions, but displayed hyperactivity from their second week of age. The role of the dopamine system in the defensive reactions was studied by variations of the dopamine activity level by traditional tools: depletion by α-methyl-tyrosin followed by replenishment by l -DOPA; stimulation or inhibition of the dopamine receptors by apomorphine or haloperidol. The results suggested an inhibitory function of the dopamine system in both defensive reactions, antagonistic to that of the serotonin system.     

Parent training for young Norwegian children with ODD and CD problems: Predictors and mediators of treatment outcome

Participants were 121 children, aged 4–8 years referred for conduct problems, and their mothers. A parent training intervention was implemented in two outpatient clinics in Norway. Treatment responders were defined as children scoring below a cut-off on the Eyberg Child Behavior Inventory, a score below an optimal cut-off for children in day-care and school as reported by teachers, in addition to a 30% reduction or greater in observed negative parenting. Self-reported parenting practices were explored as potential mediators. The results of logistic regression analyses showed that high levels of maternal stress, clinical levels of ADHD, and being a girl predicted a poorer outcome in conduct problems at home, while pretreatment clinical levels of ADHD predicted a poorer outcome as perceived by the teachers. Harsh and inconsistent parental disciplining emerged as significant partial mediators of changes in conduct problems, highlighting the importance of altering parenting practices to modify young children's conduct problems.     

Dimensions and Categories Underlying Thinking About College Student Types1

Previous work on implicit personality theory and the college student culture suggests that thinking about college student types should include academic involvement and social involvement dimensions. Further, positive and negative social, positive academic, and oppositional clusters of types were predicted based on studies of high school crowds. Using 85 college student type labels as stimuli, a free‐sorting method coupled with multidimensional scaling and hierarchical clustering analyses provided support for these hypotheses. Also, the results suggest convergence in the cognitive structure underlying perception of college student types across major demographic categories.     

An organizing framework for collective identity: articulation and significance of multidimensionality

The authors offer a framework for conceptualizing collective identity that aims to clarify and make distinctions among dimensions of identification that have not always been clearly articulated. Elements of collective identification included in this framework are self-categorization, evaluation, importance, attachment and sense of interdependence, social embeddedness, behavioral involvement, and content and meaning. For each element, the authors take note of different labels that have been used to identify what appear to be conceptually equivalent constructs, provide examples of studies that illustrate the concept, and suggest measurement approaches. Further, they discuss the potential links between elements and outcomes and how context moderates these relationships. The authors illustrate the utility of the multidimensional organizing framework by analyzing the different configuration of elements in 4 major theories of identification.     

Body Mass Index Is an Important Predictor for Suicide: Results from a Systematic Review and Meta‐Analysis

Public health concerns for the independent management of obesity and suicidal behavior are rising. Emerging evidence suggests body weight plays an important role in quantifying the risk of suicide. In light of these findings, we aimed to clarify the association between body mass index (BMI) and suicidal behavior by systematically reviewing and evaluating the literature. Studies were identified by searching MEDLINE, EMBASE, PsycINFO, and CINAHL from inception to January 2015, supplemented by hand and grey literature searches. Study screening, data extraction, and risk of bias assessment were conducted in duplicate. We included 38 observational studies. Meta‐analyses supported an inverse association between BMI and completed suicide. Pooled summary estimates demonstrated that underweight was significantly associated with an increased risk of completed suicide (HR = 1.21, 95% CI 1.07 to 1.36, p = .002), and obesity (HR = 0.71, 95% CI 0.56 to 0.89, p = .003) and overweight (HR = 0.78, 95% CI 0.75 to 0.82, p < .0001) were significantly associated with a decreased risk of completed suicide relative to normal weight. A qualitative summary of the literature demonstrated conflicting evidence regarding the association between BMI and attempted suicide and revealed no association between BMI and suicidal ideation. BMI may be used to aid the assessment of suicide risk, especially that of completed suicide. However, unmeasured confounders and systematic biases of individual studies limit the quality of evidence.
