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.     

The effects of relational structure on analogical learning

Relational structure is important for various cognitive tasks, such as analogical transfer, but its role in learning of new relational concepts is poorly understood. This article reports two experiments testing people’s ability to learn new relational categories as a function of their relational structure. In Experiment 1, each stimulus consisted of 4 objects varying on 2 dimensions. Each category was defined by two binary relations between pairs of objects. The manner in which the relations were linked (i.e., by operating on shared objects) varied between subjects, producing 3 logically different conditions. In Experiment 2, each stimulus consisted of 4 objects varying on 3 dimensions. Categories were defined by three binary relations, leading to six logically different conditions. Various learning models were compared to the behavioral data, based on the theory of schema refinement. The results highlight several shortcomings of schema refinement as a model of relational learning: (1) it can make unreasonable demands on working memory, (2) it does not allow schemas to grow in complexity, and (3) it incorrectly predicts learning is insensitive to relational structure. We propose schema elaboration as an additional mechanism that provides a more complete account, and we relate this mechanism to previous proposals regarding interactions between analogy and representation construction. The current findings may advance understanding of the cognitive mechanisms involved in learning and representing relational concepts.     

Two faces of desert

There are two broadly competing pictures of moral responsibility. On the view I favor, to be responsible for some action is to be related to it in such a way that licenses attributing certain properties to the agent, properties like blameworthiness and praiseworthiness. Responsibility is attributability. A different view understands being responsible in terms of our practices of holding each other responsible. Responsibility is accountability, which “involves a social setting in which we demand (require) certain conduct from one another and respond adversely to one another’s failures to comply with these demands” (Watson, Philos Top 24:227–248, 1996). My concern here is the relation between moral responsibility and desert. Plausibly, if someone is morally responsible for something wrong then they deserve blame, and it is on the basis of them being morally responsible and its being wrong that they deserve blame. In this paper, I try to make progress toward understanding why it would follow that being morally responsible for something supports a desert claim. I propose to do this by exploring how the “two faces” of responsibility should proceed. An important upshot is that we gain a new currency by which to evaluate extant theories of responsibility that might favor one or the other conception: do they carry plausible desert commitments? To illustrate this benefit, I argue that accountability theory carries implausible implications for deserved praise.     

The dark figure of sexual offending: A replication and extension

Studies of the dark figure of sexual offending using federal correctional clients reported significant evidence of previously unknown or hidden sexual violence, often among clients with no official criminal history. Unfortunately, research has produced variable estimates of how large the dark figure is. The current study sought to replicate recent studies of federal sexual offenders about the dark figure of sexual offending. We also extended the knowledge base by providing additional correlational analyses to see whether self-reported and official sexual offending have shared or divergent correlates. Overall, 73.8% of federal sexual offenders reported prior contact victims, which is higher than, but generally consistent with, prior prevalence estimates of 55–69% in studies of federal correctional clients. In the current data, clients convicted of child pornography possession or receipt and who had no official record of sexual abuse nevertheless reported contact sexual offenses in more than 59% of cases.     

Working memory load moderates late attentional bias in social anxiety

The vigilance–avoidance hypothesis suggests that socially anxious individuals attempt to detect signs that they are being evaluated (vigilance) and subsequently direct attention away from such stimuli (avoidance). Although extensive evidence supports vigilance, data concerning subsequent avoidance is equivocal. Drawing from models of attention, the current study hypothesised that working memory load moderates late attentional bias in social anxiety such that avoidance occurs if working memory load is low, and difficulty disengaging attention occurs if working memory load is high. Forty-one undergraduates (19 socially anxious; 22 non-anxious controls) completed a dot-probe task with emotional (happy and disgust) and neutral facial expressions and a concurrent n-back task. Results supported the hypothesis such that socially anxious subjects demonstrated avoidance of disgust faces when working memory load was absent, but had difficulty disengaging attention during high working memory load. Theoretical implications and directions for future research are discussed.     

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.     

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.     

The effects of temporal delay and orientation on haptic object recognition

We examined the effects of interstimulus interval (ISI) and orientation changes on the haptic recognition of novel objects, using a sequential shape-matching task. The stimuli consisted of 36 wedge-shaped plastic objects that varied along two shape dimensions (hole/bump and dip/ridge). Two objects were presented at either the same orientation or a different orientation, separated by either a short (3-sec) ISI or a long (15-sec) ISI. In separate conditions, ISI was blocked or randomly intermixed. Participants ignored orientation changes and matched on shape alone. Although performance was better in the mixed condition, there were no other differences between conditions. There was no decline in performance at the long ISI. There were similar, marginally significant benefits to same-orientation matching for short and long ISIs. The results suggest that the perceptual object representations activated from haptic inputs are both stable, being maintained for at least 15 sec, and orientation sensitive.
