Rethinking Cognition: On Coulter on Discourse and Mind

This paper responds to, and comments on, Coulter's (1999) critique of discursive psychology with particular reference to how cognition is conceptualised theoretically and analytically. It first identifies a number of basic misreadings of discursive psychological writings, which distort and, at times, reverse its position on the status of cognition. Second, it reviews the main ways in which cognition, mental states, and thoughts have been analytically conceptualised in discursive psychology (respecification of topics from mainstream psychology, studies of the psychological thesaurus in action, and studies of the way psychological issues are managed). Third, it considers two of Coulter's substantive issues: the role of correct usage and the role of conceptual vs. empirical analysis. A series of problems are identified with Coulter's development of both of these issues.     

Using image analysis techniques to analyze figure-copying performance of patients with visuospatial neglect and control groups.

Figure copying is often used to detect visuospatial neglect (VSN) in brain-damaged patients. We describe algorithms that enable the computation of parameters for describing figure-copying performance. The researcher can readily implement these algorithms on a computer using image analysis software, and they provide information on goodness-of-fit, relative to a standard model, as well as on dynamic aspects of subjects' performance in completing figure copies. To demonstrate the clinical utility of these algorithms, preliminary results from a group of right-hemisphere brain-damaged patients, some of whom have VSN, are compared with those for age-matched controls.     

A social validation explanation for mutual enhancement

Group members experience mutual enhancement when they evaluate one another’s task capabilities more positively because they are discussing shared as compared to unshared information. Two experiments investigated a social validation explanation for mutual enhancement. In Experiment 1, members of dyads read and discussed either shared or unshared information and collectively recalled this information under conditions where accuracy was important or not. Mutual enhancement occurred when need for accuracy was higher, but not when it was lower. In Experiment 2, members of dyads read validating or non-validating information from an outsider after they collectively recalled shared or unshared information. Members who discussed unshared information and received no validating communication from the outsider gave one another the lowest task capability ratings compared to members who discussed shared information and/or received validating communication from the outsider. All of these results are consistent with a social validation explanation for mutual enhancement.     

Be Prestige-Resilient! A Contextual Ethics of Cultural Identity

This article proposes a new social- and moral-psychological understanding of cultural identity, tailored to the mixed multicultural contexts of every major city today. Seeking to protect vulnerable cultural groups, theories of multiculturalism have insufficiently assessed the psychological significance of intercultural social comparison, in identity-formation. While plays of prestige are a fact of life for immigrant and gay minorities, not everyone is equally able to cope with ascribed negative prestige. This is shown in an analysis of reactive attitudes towards negative prestige under contrasting conditions (of rough cultural equality, and in underclass-culture). The idea of prestige-resilience is proposed both as an explanatory concept in the debate on underclass-culture and as a normative concept from which basic moral and ethical thresholds for cultural identity-formation might be deduced. Outcomes are considered relevant for psychological analysis of underclass-formation and for multicultural policy-making, specifically in immigrant states.
