Shifty talk: knowledge and causation

In this paper, I criticise one main strategy for supporting anti-intellectualism, the view that whether a subject knows may depend on the stakes. This strategy appeals to difficulties with developing contextualist and pragmatic treatments of the shiftiness of our talk about knowledge to motivate anti-intellectualism. I criticise this strategy by drawing an analogy between debates about causation and knowledge. In each case, talk about a phenomenon is shifty and contextualist and pragmatic explanations of the shifty talk face the same objections. However, in the case of causation it would be implausible to argue that difficulties with the relevant contextualist and pragmatic accounts motivate a revisionary metaphysics of causation. I conclude that the defender of anti-intellectualism needs to employ a different strategy to defend her view.     

Elevated social anxiety among early maturing girls

Adolescence is a key period in terms of the development of anxiety psychopathology. An emerging literature suggests that early pubertal maturation is associated with enhanced vulnerability for anxiety symptomatology, although few studies have examined this association with regard to social anxiety. Accordingly, the current study was designed to further elucidate the relation between pubertal timing and social anxiety, with a focus on clarifying the role of gender. Participants were 138 adolescents (ages 12-17 years) recruited from the general community. Level of social anxiety was examined as a function of gender and within-sample pubertal timing. As expected, early maturing girls evidenced significantly higher social anxiety, compared with on-time girls and early maturing boys, and no other differences were found as a function of gender or developmental timing. Findings and future directions are discussed in terms of forwarding developmentally sensitive models of social anxiety etiology and prevention.     

Tool use influences perceived shape and perceived parallelism, which serve as indirect measures of perceived distance

Targets presented just beyond arm's reach look closer when observers intend to touch them with a reach-extending tool rather than without the tool. This finding is one of several that suggest that a person's ability to act influences perceived distance to objects. However, some critics have argued that apparent action effects were actually due to effects on the judgments rather than on the perception. In other words, the target does not actually look closer, but participants report that it is. To help counter this argument, the current experiments used an indirect measure of perceived distance: Participants reported perceived shape or perceived parallelism. The results revealed that triangles looked shorter and lines looked more horizontal to participants who reached with a tool, and therefore could reach the targets, than they did to participants who reached without the tool. These results demonstrate convergence across multiple types of judgments, a finding that undermines alternative, judgment-based accounts and suggests that the ability to reach an object changes the perceived distance to the object.     

Asymmetrical Body Perception: A Possible Role for Neural Body Representations

ABSTRACT— Perception of one's body is related not only to the physical appearance of the body, but also to the neural representation of the body. The brain contains many body maps that systematically differ between right- and left-handed people. In general, the cortical representations of the right arm and right hand tend to be of greater area in the left hemisphere than in the right hemisphere for right-handed people, whereas these cortical representations tend to be symmetrical across hemispheres for left-handers. We took advantage of these naturally occurring differences and examined perceived arm length in right- and left-handed people. When looking at each arm and hand individually, right-handed participants perceived their right arms and right hands to be longer than their left arms and left hands, whereas left-handed participants perceived both arms accurately. These experiments reveal a possible relationship between implicit body maps in the brain and conscious perception of the body.     

Health Status and Peer Relationships in Early Adolescence: The Role of Peer Contact, Self-esteem, and Social Anxiety

We examined associations between children’s health status and the quality of their peer relationships, as well as factors that may account for individual variation in the quality of chronically ill and healthy children’s peer relationships. Our sample included 268 children (138 boys; 130 girls) with 149 European-Americans and 119 African-Americans. There were 91 children with a chronic illness; 35 with asthma, 26 with diabetes, and 30 with obesity. Chronically ill children were characterized by teachers as displaying less prosocial behavior, less overt aggression, and less relational aggression with peers than healthy children. Chronically ill children reported lower levels of peer contact and higher levels of social anxiety than healthy children. Among chronically ill children those with high self-esteem were more prosocial and less aggressive than those with low self-esteem. Our findings suggest that chronically ill children are at risk for peer relationship difficulties, but that self-esteem may serve as a protective factor against poor peer relationships for some chronically ill children.     

You Wore Me Down: Self‐Control Strength and Social Influence

The ability to effectively regulate one’s thoughts, feelings, and behavior is at the heart of human agency. Numerous insights in self‐regulation have recently been gained utilizing the strength, or limited‐resource, model of self‐control. Much of this work has focused on the intrapersonal impact of self‐control; however, an emerging body of work has begun to shift attention toward the interpersonal realm with similar success. In this article, we review the role that regulatory strength has in social influence. Work from persuasion, compliance, and conformity demonstrate that (1) resisting social influences consumes regulatory resources and (2) when these resources are depleted, people become more susceptible to social influences. We conclude by highlighting important implications that remain unanswered and suggest potential areas of future development.     

Categorization and cognitive deficits in compulsive hoarding

According to the cognitive-behavioural model of compulsive hoarding, information-processing deficits in the areas of attention, memory, decision-making, and categorization contribute to hoarding behaviour. The purpose of the current study was to examine whether individuals with compulsive hoarding exhibited impairment on executive functioning and categorization tasks. Three groups of participants were recruited (N = 60): individuals with compulsive hoarding syndrome, individuals with an Axis I mood or anxiety disorder, and non-clinical control participants. All participants completed self-report measures of cognitive difficulties, neuropsychological tests of executive functioning and decision-making, and four categorization tasks. Results suggested that hoarding participants reported more cognitive failures and more problems with attention and decision-making than non-clinical control participants. In addition, hoarding participants performed worse than both control groups on the Stockings of Cambridge (SOC), a neuropsychological test of planning ability, and were slower and more anxious during a categorization task. These findings suggest that specific deficits in executive functioning may be associated with the difficulties hoarding patients have organizing their possessions.
