‘The Queen Mother and I’: assimilation,contrast, and attitudes toward social groups

We examined whether social group attitudes are subject to context effects. It was hypothesised that manipulating the context in which a group exemplar was rendered accessible would produce different effects when subjects were subsequently asked to evaluate the exemplar's group. In our study, all subjects first expressed their opinion about the (popular) Queen Mother before indicating their attitude toward the British Royal Family. In the ‘non‐redundant’ condition, the two questions were structured such that the Queen Mother was expected to be included in individuals' representation of the Royal Family, leading to a high correlation between the two judgements and a favourable evaluation of the group. Conversely, in the ‘redundant’ condition, the questions were structured such that the Queen Mother was expected to be excluded from individuals' representation of the Royal Family, leading to a lower correlation between the judgements and a less favourable evaluation of the group. The results supported the hypothesis, and are consistent with the Schwarz and Bless (1992a,b) inclusion/exclusion model of assimilation and contrast. Copyright © 1999 John Wiley & Sons, Ltd.

The over‐pruning hypothesis of autism

This article outlines the over‐pruning hypothesis of autism. The hypothesis originates in a neurocomputational model of the regressive sub‐type (Thomas, Knowland & Karmiloff‐Smith, 2011a, 2011b). Here we develop a more general version of the over‐pruning hypothesis to address heterogeneity in the timing of manifestation of ASD, including new computer simulations which reconcile the different observed developmental trajectories (early onset, late onset, regression) via a single underlying atypical mechanism; and which show how unaffected siblings of individuals with ASD may differ from controls either by inheriting a milder version of the pathological mechanism or by co‐inheriting the risk factors without the pathological mechanism. The proposed atypical mechanism involves overly aggressive synaptic pruning in infancy and early childhood, an exaggeration of a normal phase of brain development. We show how the hypothesis generates novel predictions that differ from existing theories of ASD including that (1) the first few months of development in ASD will be indistinguishable from typical, and (2) the earliest atypicalities in ASD will be sensory and motor rather than social. Both predictions gain cautious support from emerging longitudinal studies of infants at‐risk of ASD. We review evidence consistent with the over‐pruning hypothesis, its relation to other current theories (including C. Frith's under‐pruning proposal; C. Frith, 2003, 2004), as well as inconsistent data and current limitations. The hypothesis situates causal accounts of ASD within a framework of protective and risk factors (Newschaffer et al., 2012); clarifies different versions of the broader autism phenotype (i.e. the implication of observed similarities between individuals with autism and their family members); and integrates data from multiple disciplines, including behavioural studies, neuroscience studies, genetics, and intervention studies.     

Trunk-Assisted Prehension: Specification of Body Segments With Imposed Temporal Constraints

The authors used a trunk-assisted prehension task to examine intersegment coordination. Participants (N = 7) reached to grasp an object placed beyond full arm extension, thus requiring trunk flexion to achieve the target object, under 4 varying temporal constraints. Kinematic analyses were performed in which the motions of the arm, the trunk, and the endpoint were characterized. The spatial trajectories and the segments' peak velocity data revealed that under high temporal constraints the arm was more responsible for endpoint motion than the trunk, whereas in the unconstrained condition the trunk was more involved. In addition, the arm exhibited a decline in spatial variability toward the end of the movement in all conditions, whereas the trunk did not. The present study is the first to show that when temporal demand is increased for a trunk-assisted prehensile task, the arm plays a larger role than the trunk in the transport of the hand to the object The data also suggest that the arm participates in the fine accuracy control of the reach, whereas the trunk does not.

Complex Prospective Memory in Children with ADHD

The ability to remember intentions (prospective memory) is fundamental to the organization of goal-directed actions in everyday life. Successful prospective remembering involves forming, retaining, initiating, and executing an intention. Although previous research has demonstrated prospective memory impairments in children with attention deficit/hyperactivity disorder (ADHD), this has largely focused on the intention initiation and execution stages. In this study, we investigate the performance of 20 children with ADHD and 20 matched controls at each of the four stages of prospective memory, using a computer multitask paradigm. Results suggest that children with ADHD may demonstrate difficulties forming delayed intentions, as indicated by impulsive planning, and that this may have further implications for the retention and implementation of these delayed intentions. While children with ADHD showed comparable multitask switching, this appeared to be at the expense of intention execution as they made more performance errors than controls. Implications for day-to-day functioning are discussed.     

Impact of Organizational Citizenship Behavior on Performance in Women's Sport Teams

The current study examined the relationship between organizational citizenship behavior and sport team performance and the moderating role of task interdependence in that relationship. Two types of collegiate teams—softball (N = 25) and tennis (N = 15)—were utilized to represent different levels of task interdependence with softball being considered more interdependent than tennis. Athletes (N = 448) answered survey questions concerning organizational citizenship behavior (helping, civic virtue, sportsmanship [due to the historic use of the term “sportmanship” in developing the measures used in this study, that term will be used instead of “sportpersonship”]), team cohesiveness, athlete satisfaction, and transformational leadership behaviors. Researchers collected performance statistics for athletes. Results indicated that helping behavior was the strongest organizational citizenship behavior predictor of performance, but the effect differed between tennis and softball teams.     

Historicizing the Role of Psychologists in the U.S. Military: Introduction to Issue on Coercive Interrogations and the Mental Health Profession

This special issue addresses the disturbing events that emerged in the aftermath of 9/11 in the United States with regard to the role of mental health professionals in coercive interrogations of detainees held in detention centers and military “black sites.” While other professional associations condemned such practices, the American Psychological Association maintained a position of collaboration, despite activist members' protests.

These events will be examined in an effort to reconstitute our history as a profession through the actions of what Freud called “nachtraeglichkeit’, (deferred action) in which the unassimilated experiences of the past relationship between psychology and the military will be used to transform our perceptions and future directions. This introduction also summarizes the papers in this issue. These include a history of the interrogation practices and the controversy within the APA; a history of the long-standing relationship between the profession of psychology and government, military, and intelligence organizations; analyses of the psychology of torture and evidence of how this psychology is manifested in the consulting room; a comparison of psychological structures within the population and mental health professions in the United States today and Argentina during recent totalitarian regimes; and an interview with Robert Lifton, eminent psychohistorian, psychiatrist and political activist.
