Working Memory Deficits and Social Problems in Children with ADHD

Social problems are a prevalent feature of ADHD and reflect a major source of functional impairment for these children. The current study examined the impact of working memory deficits on parent- and teacher-reported social problems in a sample of children with ADHD and typically developing boys (N = 39). Bootstrapped, bias-corrected mediation analyses revealed that the impact of working memory deficits on social problems is primarily indirect. That is, impaired social interactions in children with ADHD reflect, to a significant extent, the behavioral outcome of being unable to maintain a focus of attention on information within working memory while simultaneously dividing attention among multiple, on-going events and social cues occurring within the environment. Central executive deficits impacted social problems through both inattentive and impulsive-hyperactive symptoms, whereas the subsidiary phonological and visuospatial storage/rehearsal systems demonstrated a more limited yet distinct relationship with children’s social problems.     

Age-of-Onset or Behavioral Sub-Types? A Prospective Comparison of Two Approaches to Characterizing the Heterogeneity within Antisocial Behavior

There are two common approaches to sub-typing the well-documented heterogeneity within antisocial behavior: age-of-onset (i.e., childhood-onset versus adolescence-onset; see Moffitt 1993) and behavioral (i.e., physical aggression versus non-aggressive rule-breaking). These approaches appear to be associated, such that aggression is more characteristic of childhood-onset antisocial behavior whereas rule-breaking is linked to both child- and adolescence-onset antisocial behavior. However, it remains unclear which approach, if either, better explains the heterogeneity within antisocial behavior. We examined this question in a prospective sample of male twins, assessed at the ages of 11, 14, 17, and 24 years. Although the age-of-onset subtypes predicted adult antisocial behavior in the expected direction when analyzed alone, this association dissipated once we controlled for aggression and rule-breaking. Such findings suggest that the behavioral sub-types of antisocial behavior may be a stronger predictor of later antisocial outcomes than is its age-of-onset.     

Bayesian Fundamentalism or Enlightenment? On the explanatory status and theoretical contributions of Bayesian models of cognition

The prominence of Bayesian modeling of cognition has increased recently largely because of mathematical advances in specifying and deriving predictions from complex probabilistic models. Much of this research aims to demonstrate that cognitive behavior can be explained from rational principles alone, without recourse to psychological or neurological processes and representations. We note commonalities between this rational approach and other movements in psychology - namely, Behaviorism and evolutionary psychology - that set aside mechanistic explanations or make use of optimality assumptions. Through these comparisons, we identify a number of challenges that limit the rational program's potential contribution to psychological theory. Specifically, rational Bayesian models are significantly unconstrained, both because they are uninformed by a wide range of process-level data and because their assumptions about the environment are generally not grounded in empirical measurement. The psychological implications of most Bayesian models are also unclear. Bayesian inference itself is conceptually trivial, but strong assumptions are often embedded in the hypothesis sets and the approximation algorithms used to derive model predictions, without a clear delineation between psychological commitments and implementational details. Comparing multiple Bayesian models of the same task is rare, as is the realization that many Bayesian models recapitulate existing (mechanistic level) theories. Despite the expressive power of current Bayesian models, we argue they must be developed in conjunction with mechanistic considerations to offer substantive explanations of cognition. We lay out several means for such an integration, which take into account the representations on which Bayesian inference operates, as well as the algorithms and heuristics that carry it out. We argue this unification will better facilitate lasting contributions to psychological theory, avoiding the pitfalls that have plagued previous theoretical movements.     

Learning associations between action and perception: effects of incompatible training on body part and spatial priming

Observation of another person executing an action primes the same action in the observer's motor system. Recent evidence has shown that these priming effects are flexible, where training of new associations, such as making a foot response when viewing a moving hand, can reduce standard action priming effects (Gillmeister, Catmur, Liepelt, Brass, & Heyes, 2008). Previously, these effects were obtained after explicit learning tasks in which the trained action was cued by the content of a visual stimulus. Here we report similar learning processes in an implicit task in which the participant's action is self-selected, and subsequent visual effects are determined by the nature of that action. Importantly, we show that these learning processes are specific to associations between actions and viewed body parts, in that incompatible spatial training did not influence body part or spatial priming effects. Our results are consistent with models of visuomotor learning that place particular emphasis on the repeated experience of watching oneself perform an action.     

Validating a measure of children's monitoring-blunting coping styles in dental situations

The monitoring-blunting theory of coping suggests that when faced with a threatening situation, individuals can respond by either monitoring or avoiding (blunting) threatening information. The current study sought to validate a scale of children's preferences for monitoring or blunting in dental situations (the Monitoring Blunting Dental Scale or MBDS). The psychometric characteristics of the scale were assessed in a sample of 240 New Zealand children aged 11-13. Reliability was adequate for both monitoring (α = 0.74) and blunting (α = 0.76) subscale scores. Convergent validity was indicated by strong correlations (>0.6) between the measure's subscales and those of a related scale, although discriminant validity with respect to dental anxiety was problematic for the blunting subscale. Exploratory factor analysis supported a two-factor monitoring-blunting model, although confirmatory factor analysis indicated reasonable but imperfect fit for this model, SBχ2(251) = 510.7, p < 0.001, RMSEA = 0.066. We reflect on conceptual issues which may underlie the difficulties experienced here and elsewhere in developing psychometrically sound measures of Miller's blunting construct and suggest that the monitoring subscale of the study scale may be most useful to other researchers.     

The family empowerment program: an interdisciplinary approach to working with multi-stressed urban families

The family empowerment program (FEP) is a multi-systemic family therapy program that partners multi-stressed families with an interdisciplinary resource team while remaining attached to a "traditional" mental health clinic. The rationale for this model is that far too often, families presenting at community mental health centers struggle with multiple psychosocial forces, for example problems with housing, domestic violence, child care, entitlements, racism, substance abuse, and foster care, as well as chronic medical and psychiatric illnesses, that exacerbate symptoms and impact traditional service delivery and access to effective treatment. Thus, families often experience fragmented care and are involved with multiple systems with contradictory and competing agendas. As a result, services frequently fail to harness the family's inherent strengths. The FEP partners the family with a unified team that includes representatives from Entitlements Services, Family Support and Parent Advocacy, and Clinical Staff from the agency's Outpatient Mental Health Clinic practicing from a strength-based family therapy perspective. The goal of the FEP is to support the family in achieving their goals. This is accomplished through co-construction of a service plan that addresses the family's needs in an efficient and coherent manner-emphasizing family strengths and competencies and supporting family self-sufficiency.     

The aftermath of destruction: Images of destroyed buildings increase support for war,dogmatism, and death thought accessibility

Building on terror management theory, we hypothesized that viewing destroyed buildings would increase death thought accessibility and thereby elicit dogmatic belief and hostile worldview defenses. In Study 1, images of destroyed buildings and deadly terrorist attacks elicited greater death-thought accessibility than images of construction sites or intact buildings. Images of destruction also enhanced dogmatic belief (Study 2) and support for military action against Iran (Study 3). Study 4 found that heightened death thought accessibility, but not the accessibility of thoughts of war or national identity, statistically mediated the relationship between visible destruction and worldview defense. Further, although destruction images increased dogmatism, political orientation was not affected by the destruction manipulation nor was political orientation related to death-thought accessibility. Overall, these findings suggest that visibly destroyed infrastructure can motivate increased certainty of beliefs and support for military aggression (e.g., war and/or terrorism) against groups perceived to be threatening to one's worldview.     

A media analysis of a sport celebrity: Understanding an informal “team cancer” role as a socio-cultural construction

Objectives

Negative informal roles in sport such as a “team cancer” warrant further attention because of the association with athletes’ negative psychological experiences, impaired team processes, and reduced performance. The purpose of the current study is to extend understandings of the team cancer role by analyzing the socio-cultural context (i.e., sport media narratives surrounding a sport celebrity and key media incident) within which one “team cancer” was constituted in a professional sport context.

Method

National Hockey League (NHL) star Sean Avery was the sport celebrity of interest. The key media incident was the “sloppy seconds” comment made by Avery regarding his former girlfriend. The comment was an attack towards the opposing team’s defenseman, who was dating her. Newspaper representations of the comment (n = 62) were explored via ethnographic content analysis (see Altheide, 1996).

Results

It was found that the depiction of the team cancer emerged differently depending on two paradoxical discourses found within the media: a hockey moral code as truth vs. a hockey moral code as hypocrisy. This paradox surrounding the morality of sport was exemplified within the two hockey moral code discourses surrounding the personification of Avery’s team cancer identity and the “sloppy seconds incident”.

Conclusions

This study adds to our understanding regarding how the media influences the construction of an informal team cancer role from one professional sport incident. This focus opens up a window of new understandings and possibilities for research and application beyond current theories and understandings of negative informal team roles in sport psychology.     

Consequences of anticipatory processing on cognitive symptoms of social anxiety

Anticipatory processing is an anxious style of repetitive negative thought associated with social anxiety (SA) that was proposed by Clark and Wells. Considerable research has examined factors of Clark and Wells' cognitive model of SA (e.g. attention, interpretation), but few studies have examined anticipatory processing, which is hypothesized to interact with other components in the model. In the current study, individuals high in social anxiety symptoms (HSA; N = 56) and control participants [Normal Control (NC); N = 52] engaged in an anticipation or distraction task prior to a threatened social interaction. HSAs who anticipated had higher self-focused attention than NCs who anticipated and HSAs in the distraction condition, suggesting an important relationship between anticipation and self-focus that is specific to HSAs. Those who anticipated endorsed more negative interpretations than those who engaged in distraction, regardless of SA status. However, this relationship was mediated by self-focus. Implications in the context of Clark and Wells' model and future directions are discussed.
