Post-Traumatic Reactions in Adolescents: How Well Do the DSM-IV PTSD Criteria Fit the Real Life Experience of Trauma Exposed Youth?

This study examined the structure and symptom specific patterns of post traumatic distress in a sample of 1,581 adolescents who reported exposure to at least one traumatic event. Symptom reporting patterns are consistent with past literature in that females reported more symptoms than males and older youth reported more symptoms than did their younger peers. Young people reporting exposure to exclusively violent type traumas were also found to be more likely to endorse symptoms than peers exposed exclusively to non violent type traumas. Confirmatory factor analysis provided stronger support for a four-factor model of PTSD than either the DSM-IV model or an alternate model. Further examination of the four factor model revealed gender differences in factor loadings with small to moderate effect sizes for recurrent, distressing memories, flashbacks, restricted affect, difficulty remember details, detachment, limited future orientation, hypervigilance and startle symptoms. Differences in factor loadings with the four factor model were also noted between younger and older adolescents, with medium to large effect sizes on the arousal items. In contract, comparison of the factor loadings revealed only small differences between youth exposed exclusively to violent traumatic stressors and those exposed exclusively to non violent traumatic stressors, suggesting relative similarity between these two groups.     

The Rights of Man: Libertarian Concern for Men's,But Not Women's,Reproductive Autonomy

Libertarianism enshrines individual autonomy as its central political principle, but it has been criticized for applying this principle selectively. Reproductive decisions can stress the concept of individual autonomy by placing into conflict the claimed rights of each biological parent to choose. Two studies (N₁ = 296; N₂ = 580) show that among U.S. participants, libertarianism is associated with opposition to women's reproductive autonomy and support for men's. Libertarianism was associated with opposition to abortion rights and support for men's right both to prevent women from having abortions (male veto) and to withdraw financial support for a child when women refuse to terminate the pregnancy (financial abortion). Adjusting for the association between libertarianism and conservatism, only the relationship with opposition to abortion rights was rendered nonsignificant. Mediation analyses suggest that hostile sexism may account for libertarians' selective support for men's and not women's reproductive autonomy.     

What do philosophers believe?

What are the philosophical views of contemporary professional philosophers? We surveyed many professional philosophers in order to help determine their views on 30 central philosophical issues. This article documents the results. It also reveals correlations among philosophical views and between these views and factors such as age, gender, and nationality. A factor analysis suggests that an individual’s views on these issues factor into a few underlying components that predict much of the variation in those views. The results of a metasurvey also suggest that many of the results of the survey are surprising: philosophers as a whole have quite inaccurate beliefs about the distribution of philosophical views in the profession.     

The effect of the Müller-Lyer illusion on the planning and control of manual aiming movements

Two experiments used Müller-Lyer stimuli to test the predictions of the planning-control model (S. Glover, 2002) for aiming movements. In Experiment 1, participants aimed to stimuli that either remained the same or changed upon movement initiation. Experiment 2 was identical except that the duration of visual feedback for online control was manipulated. The authors found that the figures visible during movement planning and online control had additive effects on endpoint bias, even when participants had ample time to use visual feedback to modify their movements (Experiment 2). These findings are problematic not only for the planning-control model but also for A. D. Milner and M. A. Goodale's (1995) two visual system explanation of illusory bias. Although our results are consistent with the idea that a single representation is used for perception, movement planning, and online control (e.g., V. H. Franz, 2001), other work from our laboratory and elsewhere suggests that the manner in which space is coded depends on constraints associated with the specific task, such as the visual cues available to the performer.     

The energetics of motivated cognition: a force-field analysis

A force-field theory of motivated cognition is presented and applied to a broad variety of phenomena in social judgment and self-regulation. Purposeful cognitive activity is assumed to be propelled by a driving force and opposed by a restraining force. Potential driving force represents the maximal amount of energy an individual is prepared to invest in a cognitive activity. Effective driving force corresponds to the amount of energy he or she actually invests in attempt to match the restraining force. Magnitude of the potential driving force derives from a combination of goal importance and the pool of available mental resources, whereas magnitude of the restraining force derives from an individual's inclination to conserve resources, current task demands, and competing goals. The present analysis has implications for choice of means to achieve one's cognitive goals as well as for successful goal attainment under specific force-field constellations. Empirical evidence for these effects is considered, and the underlying theory's integrative potential is highlighted. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Once a French Speaker,Always a French Speaker? Bilingual Children's Thinking About the Stability of Language

Despite early emerging and impressive linguistic abilities, young children demonstrate ostensibly puzzling beliefs about the nature of language. In some circumstances monolingual children even express the belief that an individual's language is more stable than her race. The present research investigated bilingual children's thinking about the relative stability of language and race (Kinzler & Dautel, 2012). Five‐to six‐year‐old bilingual children were asked to judge whether a target child who varied in race (White or Black) and language (English or French) would grow up to be an adult who maintained the target child's race or her language. Similar to many monolingual children, a heterogeneous group of bilingual children on average chose the language‐match. Yet French‐English bilingual children were relatively more likely to choose the race‐match, especially when tested in their non‐dominant language. Specific experience with relevant languages, and communicating in a non‐dominant language, may contribute to children's developing metalinguistic success and their thinking about social categorization.     

The effects of early relational antecedents and other factors on the parental sensitivity of mothers and fathers

This study examines the effect of early relational antecedents (ERA, i.e. the quality of parenting parents recalled receiving as children), parenting stress, marital stress, socio‐economic factors and children's characteristics (gender and disability condition) on the parental sensitivity of mothers and fathers. The sample consisted of 116 mothers and 84 fathers of 117 eighteen month old children drawn from a larger longitudinal study on the adaptation of parents to a child with a disability. Thirty‐four children were diagnosed with Down syndrome (DS), 51 with a cleft lip and/or palate (CLP), and 32 were non‐disabled children. Multiple regression analyses reveal that mothers' sensitivity is best predicted by her level of education and family income, whereas fathers' sensitivity is best predicted by their ERA, marital stress, family income and the child's disability condition. Mothers with more education and a greater family income displayed a greater sensitivity to their children, as did fathers who perceive less marital stress, those with a greater family income and those who perceived their parents as less controlling. Also, fathers of children with DS displayed less sensitivity for their children than fathers of children with CLP or fathers of non‐disabled children. These results concord with many studies about the importance of socio‐economic factors, ERA, marital stress, parent's gender and children's factors in the understanding of parental sensitivity.
