Reconsidering the role of movement in perceiving action-scaled affordances

Many locomotor tasks require actors to choose among different categories of action, such as when deciding whether to cross the street in front of an approaching vehicle or wait until it passes. In such cases, the actor’s locomotor capabilities partly determine which actions are possible, and therefore must be taken into account. The present study was designed to re-evaluate the claim that people do not know their locomotor capabilities until they begin moving because they rely entirely on information that is picked up “on the fly” (Oudejans, Michaels, Bakker, & Dolné, 1996). Three experiments were conducted in which participants judged while stationary or moving whether it was within their capabilities to catch a fly ball or pass through a shrinking gap. The main finding was that judgments were equally accurate regardless of whether participants were stationary or allowed to move for a brief period. We conclude that stationary and moving actors know their locomotor capabilities equally well, and that actors do not rely entirely on information that is picked up on the fly.     

Psychological maturity and change in adult defense mechanisms

Change in the use of defense mechanisms between late adolescence and adulthood was assessed in two different longitudinal studies from the Institute of Human Development. The results were virtually identical: the use of Identification decreased, the use of Denial increased, and there was little change in the use of Projection. Both the use of Identification at adolescence, and its subsequent decrease in adulthood were found to be predicted by ego strength and committed Identity - that is, by evidence of developmental maturity at late adolescence. The decrease in Identification is consistent with predictions from the theory of defense mechanism development: defenses are related to developmental period; once that period is concluded, the use of the related defense declines.     

A Trait‐Interpersonal Analysis of Suicide Proneness Among Lesbian,Gay, and Bisexual Community Members

Suicide remains a concerning issue for lesbian, gay, and bisexual (LGB) persons. The integrated effects of five‐factor model personality traits and interpersonal‐psychological theory of suicide (IPTS) constructs on suicide proneness in a community sample of 336 LGB adults were examined. Results supported a model inclusive of all five‐factor model domains predicting IPTS constructs leading to suicide proneness. Effects of neuroticism and extraversion were both mediated by perceived burdensomeness and thwarted belongingness. Thwarted belongingness mediated the effect of agreeableness on suicide proneness. Identified mediation pathways build on existing trait‐interpersonal theory and may inform clinical services for sexual minority persons.     

A qualitative investigation of mock-jurors' theories of emotion and reason

Mock-juries' deliberations of murder/manslaughter verdicts were videotaped and analysed. It was found that jurors' deliberations incorporated their theories of emotion and of the relationship between emotion and reason. Although there was agreement among jurors that emotions can overwhelm persons' rational faculties, there was disagreement between jurors voting for murder and for manslaughter as to the relationship of emotion and reason. Jurors voting for murder suggested emotion and reason are interdependent and that persons can simultaneously act from emotion as well as reason, whereas jurors voting for manslaughter suggested the two are independent and that they cannot operate simultaneously. The import of jurors' folk concepts of emotion and reason to the legal system, as well as to our understanding of emotions themselves, is discussed.
