The Biological Basis of Social Interaction

The fact that brain disorder can impair social interactions in different ways suggests that social competence has multiple components that have foundations in brain systems. The physiological basis of one aspect of social cognition, theory of mind, is just beginning to be understood. Brain-imaging studies suggest that a network of areas linking medial prefrontal and temporal cortex forms the neural substrate of mentalizing, that is, representing one's own and other people's mental states. The medial prefrontal areas are prominent also in tasks that involve self-monitoring, whereas the temporal regions are prominent also in tasks that involve the representation of goals of actions. We speculate that the precursors of mentalizing ability derive from a brain system that evolved for representing agents and actions, and the relationships between them.     

The Objectivity of Mathematics

The purpose of this paper is to apply Crispin Wright’s criteria and various axes of objectivity to mathematics. I test the criteria and the objectivity of mathematics against each other. Along the way, various issues concerning general logic and epistemology are encountered.     

When Likeness Goes with Liking: The Case of Political Preference

Three studies show that people tend to vote for politicians (i.e., either Romano Prodi or Silvio Berlusconi in Italy or George W. Bush or John Kerry in the United States) whose traits they rate as being most similar to their own. People perceived higher similarity between themselves and political figures with respect to traits that were most distinctive of each platform and their respective leaders. These findings, while corroborating the similarity-attraction relationship, further attest to the role that personal characteristics of both voters and candidates play in orienting political preference.     

Effects of Dangerous and Competitive Worldviews on Right-Wing Authoritarianism and Social Dominance Orientation over a Five-Month Period

The cross-lagged effects of dangerous and competitive social worldviews on Right-Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) were examined over a five-month period ( N   =  165). Analyses indicated that the motivational goal for group-based dominance and superiority indexed by SDO changed as a function of the degree to which the social world was perceived as a competitive place characterized by inequality and resource scarcity. The motivational goal for ingroup conformity and collective security indexed by RWA, in contrast, changed as a function of the degree to which the social world was perceived as a dangerous and threatening place prone to high levels of crime and immoral behavior. These findings are consistent with the causal pathways between social worldviews and ideological attitudes predicted by Duckitt's (2001 ) model of the dual motivational and cognitive processes underlying prejudice. An unexpected reciprocal effect in which RWA predicted longitudinal change in dangerous worldview was also identified, suggesting that the relationship between these two constructs may be more complex than previously hypothesized.     

Dignity and the right to be lesbian or gay

Richard Mohr emphasizes the importance of dispelling false beliefs about lesbians and gay men, and establishing legislation that protects the rights of sexual minorities. He argues that homophobic policies originate in the belief that gay men and lesbians are categorically less morally valuable than others, rather than deserving of unequal treatment because of their behaviors or actions. In response, I show that homophobic panic over lesbian or gay sex acts is actually quite influential, and argue that Mohr fails to take account of the political and philosophical significance of sexual freedom, and the inextricability of sexual being and sexual doing.

Item-specific adaptation and the conflict-monitoring hypothesis: a computational model

M. M. Botvinick, T. S. Braver, D. M. Barch, C. S. Carter, and J. D. Cohen (2001) implemented their conflict-monitoring hypothesis of cognitive control in a series of computational models. The authors of the current article first demonstrate that M. M. Botvinick et al.'s (2001) conflict-monitoring Stroop model fails to simulate L. L. Jacoby, D. S. Lindsay, and S. Hessels's (2003) report of an item-specific proportion-congruent (ISPC) effect in the Stroop task. The authors then implement a variant of M. M. Botvinick et al.'s model based on the assumption that control must be able to operate at the item level. This model successfully simulates the ISPC effect. In addition, the model provides an alternative to M. M. Botvinick et al.'s explanation of the list-level proportion-congruent effect in terms of an ISPC effect. Implications of the present modeling effort are discussed.     

The affect heuristic and the attractiveness of simple gambles

Prior studies have observed that the attractiveness of playing a simple gamble (7/36 to win $9; otherwise win nothing) is greatly enhanced by introducing a small loss (7/36 win $9; otherwise lose 5¢). The present studies tested and confirmed an explanation of this finding based on the concept of evaluability and the affect heuristic. Evaluators of the “no‐loss” gamble lack a precise feeling for how good $9 is, hence give it little weight in their judgment. In the second gamble, comparison with the small loss makes $9 “come alive with feeling” and become weighted in the judgment, thus increasing the attractiveness of the gamble. These results demonstrate the importance of contextual factors in determining affect and preference for simple risk‐taking opportunities. They show that the meaning, utility, and weighting of even a very familiar monetary outcome such as $9 is not fixed, but depends greatly on these contextual factors.

Counselling psychologists in academia: Life satisfaction and work and family role commitments

We examined the life satisfaction of men and women counselling psychology faculty who were Division 17 (Society of Counseling Psychology) members of APA (American Psychological Association). Self-efficacy for multiple role management, coping style, and work-family role orientation were considered as predictors of life satisfaction. Results indicated that men scored significantly higher on employee role and self role self-efficacy as compared to women, and that women as compared to men scored higher on seeking social support coping. No significant sex difference was found for role orientation or life satisfaction. Findings revealed that spouse/partner self-efficacy and problem-solving coping emerged as significant predictors of men and women's life satisfaction and accounted for 31% of the total variance.     

Autobiographical memory for trauma: update on four controversies

Empirical research since the year 2000 on trauma and autobiographical memory in adults is reviewed and related to four enduring controversies in the field: Whether traumatic memories are inherently different from other types of autobiographical memory; whether memory for trauma is better or worse than memory for non-traumatic events; whether traumas can be forgotten and then recalled later in life; and whether special mechanisms such as repression or dissociation are required to account for any such forgetting. The review concludes that trauma and non-trauma memories differ substantially, but only in clinical and not in healthy populations. Whereas involuntary memory is enhanced in clinical populations, voluntary memory is likely to be fragmented, disorganised, and incomplete. Progress in experimental and neuroimaging research will depend on analysing how task performance is affected by the interaction of voluntary and involuntary memory and by individual tendencies to respond to trauma with increased arousal versus dissociation.     

Diminished episodic memory awareness in older adults: evidence from feeling-of-knowing and recollection

The ability to reflect on and monitor memory processes is one of the most investigated metamemory functions, and one of the important ways consciousnesses interacts with memory. The feeling-of-knowing (FOK) is one task used to evaluate individual's capacity to monitor their memory. We examined this reflective function of metacognition in older adults. We explored the contribution of metacognition to episodic memory impairment, in relation to the idea that older adults show a reduction in memory awareness characteristic of episodic memory. A first experiment showed that age affects the accuracy of FOK when predictions are made on an episodic memory task but not on a semantic memory task, suggesting a particular role for episodic memory awareness in metacognitive evaluations. A second experiment showed that the age-difference in episodic FOK accuracy was removed if one took into account subjective reports of memory awareness, or recollection. We argue that the FOK deficit specific to episodic memory is based on a lack of memory awareness manifest as a recollection deficit.
