Visuospatial attention in schizophrenia: deficits in broad monitoring

Although selective attention is thought to be impaired in people with schizophrenia (PSZ), prior research has found no deficit in the ability to select one location and withdraw attention from another. PSZ and healthy control subjects (HCS) performed a stimulus detection task in which one, two, or all four peripheral target locations were cued. When one or two locations were cued, both PSZ and HCS responded faster when the target appeared at a cued than uncued location. However, increases in the number of validly cued locations had much more deleterious effects on performance for PSZ than HCS, especially for targets of low contrast whose detection was more dependent on attention. PSZ also responded more slowly in trials with four cued locations relative to trials with one or two invalidly cued locations. Thus, visuospatial attention deficits in schizophrenia arise when broad monitoring is required rather than when attention must be focused narrowly.     

When does event valence affect unrealistic optimism?

"Unrealistic optimism" (UO) has been found to be greater for negative (i.e. undesirable) than for positive (i.e. desirable) events. In two studies, we tested whether this "valence effect" is explicable in terms of motivational processes. In each case, participants were students (n = 159 in Study 1, n = 90 in Study 2), UO for the same health event was measured, and valence was manipulated by framing the event either negatively or positively. The degree to which the event would be expected to evoke concern was varied by manipulating the ease with which it could be avoided (Study 1) or the severity of its consequences (Study 2). A similar pattern of results was found in each study: the valence effect was exhibited in the condition where the event would have evoked concern, but not in the condition where it would have evoked little concern. The findings are in accord with an explanation of the valence effect in motivational terms. Implications for health education are discussed.     

Gender differences in children's divergent thinking

Block's theory (1984) of gender differences was examined to determine if it could explain inconsistencies in the reports of gender differences and the personality correlates of creativity in children. Additionally, an investigation of 244 gifted children in grades 4 to 8 is described. Two divergent thinking tests, each with a familiar and an unfamiliar item, were used to test cognitive style. The Dependency Proneness Test was used to measure independence, and the Fundamental Interpersonal Relations Orientation‐Behavior Children was used to measure social orientation. No gender differences were found on the measures of personality and cognitive style, and no significant association was found between cognitive style and personality. The results were discussed in light of the moderating influence of sex‐role flexibility and the relative freedom boys and girls experience in peer groups and play.     

Team reasoning: Solving the puzzle of coordination

In many everyday activities, individuals have a common interest in coordinating their actions. Orthodox game theory cannot explain such intuitively obvious forms of coordination as the selection of an outcome that is best for all in a common-interest game. Theories of team reasoning provide a convincing solution by proposing that people are sometimes motivated to maximize the collective payoff of a group and that they adopt a distinctive mode of reasoning from preferences to decisions. This also offers a compelling explanation of cooperation in social dilemmas. A review of team reasoning and related theories suggests how team reasoning could be incorporated into psychological theories of group identification and social value orientation theory to provide a deeper understanding of these phenomena.     

Spiritual Heroes,Miracle Tales,and Rāmsnehī Foundations: Constructing Hagiographies of a Rajasthani <Emphasis Type="Italic">Sant</Emphasis>

In 1982, a Rāmsnehī sant named Vintiram wrote a Hindi prose biography of his lineage’s founder, Rāmcara? of Shahpura (1720–98), quoting liberally from previous hagiographical verse. Although the late verse narratives showcase miracles, the earliest presents a believable story about a sant from a mercantile caste attracting initial followers among people of similar backgrounds, who spread their new sect through caste networks and make strategic political interventions. The paper examines the significance of Rāmcara? as a sant in post-Mughal Rajasthan and Vintiram’s representation of him to his own contemporaries.
