Behavioral and physiological findings of gender differences in global-local visual processing

Hemispheric asymmetries in global-local visual processing are well-established, as are gender differences in cognition. Although hemispheric asymmetry presumably underlies gender differences in cognition, the literature on gender differences in global-local processing is sparse. We employed event related brain potential (ERP) recordings during performance of a global-local reaction time task to compare hemispheric asymmetries and processing biases in adult men (n=15) and women (n=15). Women responded more quickly to local targets while men did not differentially respond to hierarchical stimuli. ERP data indicated that women had P100 responses that were selectively lateralized to the left hemisphere in response to local targets and N150 responses that were smaller for global targets. They also had P300 responses that were greater following local stimuli. The physiological data demonstrate that male-female performance differences arise from biologically based differences in hemispheric asymmetry. Findings are discussed in the context of existing literature regarding gender differences, hemispheric specialization, and the role of stimulus characteristics.     

Introducing uninteresting tasks to children: a comparison of the effects of rewards and autonomy support

Two experiments compared rewards and autonomy support as methods to promote children's self-regulation for an uninteresting vigilance task. Dependent measures were ratings of positive affect, perception of the task's value, and free-choice engagement. ANOVA results revealed some positive effects associated with autonomy support, whereas no effect for rewards was found in either study. The outcomes of most interest were correlations between free-choice behavior and self-reported measures of affect and value, reflecting the level of integration in self-regulation. As predicted by self-determination theory (Deci & Ryan, 1985, 1991, 2000), rewards were associated with behaviors incongruent from affect and value, whereas autonomy support led to integrated self-regulation. This finding was first detected in Study 1 and later replicated in Study 2. Together, these results point to autonomy support as a beneficial alternative to the common use of rewards.     

A longitudinal study of the relationship of maternal autonomy support to children's adjustment and achievement in school

A longitudinal study examined the relations of maternal autonomy support to children's school adjustment. Autonomy support and other parenting dimensions were measured when children were 5 years old. School measures were teacher-rated academic and social adjustment and achievement in reading and math in grade 3. Regression analyses controlling for age 5 family and child factors (e.g., socioeconomic status [SES], kindergarten adjustment, IQ) revealed that autonomy support was positively related to grade 3 adjustment (social and academic) and reading achievement. Maternal emphasis on school performance was positively related to achievement measures but negatively related to social adjustment. Maternal use of rewards and praise was unrelated to grade 3 school measures. Finally, supplemental analyses revealed that autonomy support was associated with greater consistency in children's adjustment across social and academic domains as well as higher overall adjustment. These results highlight the developmental significance of parental autonomy support in early childhood.     

A multilevel analysis of the interpersonal behavior of socially anxious people

We investigate the interpersonal behavior of socially anxious (SA) and non-socially anxious (NSA) individuals at three different levels of analysis, focusing on the dimensions of warmth and dominance. Study 1 examines self-reported general interaction styles, Study 2 explores behavior occurring within the context of a single interaction, and in Study 3 we focus on the performance of a single conversational act (a disagreement). Studies 1 and 2 adopt the framework of Interpersonal Circumplex Theory (IPC; Kiesler, 1983), which is well suited for studying trait-level and interaction-level social behaviors, while Study 3 is grounded in Politeness Theory (PT; Brown & Levinson, 1987), which can be used to analyze individual acts at the microstructural level. The potential mutual relevance of PT and IPC is also discussed.     

Dating violence in the United Kingdom: A preliminary study

A small-scale study of “dating violence” in a sample of UK college students is described. Methodology involved the rating-scale used in existing US studies, with the addition of an assessment of inter-respondent reliability, which was found to be high. A high incidence of some form of violence was found, with women showing higher levels than men, thus replicating previous US findings based on victim reports. Violence in the present relationship was found to be unrelated to violence in past relationships.     

Less exploring by mouth occurs in newborns of depressed mothers

Twenty‐four newborns (M age = 12 days) of depressed and nondepressed mothers were assessed for oral perception of a nubby and smooth texture. Both groups of newborns discriminated between these textures and showed a sucking preference for the smooth texture. However, the newborns of depressed mothers spent 50% less time orally exploring the stimuli, one‐third less time exploring the more novel nubby texture, and 59% less time mouthing the smooth texture. Newborns of depressed mothers may have biological differences that affect their emotional arousal and emotional regulation (e.g., capacity for self‐soothing). © 2000 Michigan Association for Infant Mental Health.     

Why,and to What Extent,Is Sexual Infidelity Wrong?

Sexual infidelity is widespread, but it is also widely condemned, yet relatively little philosophical work has been done on what makes it wrong and how wrong it is. In this paper, I argue that sexual infidelity is wrong if it involves breaking a commitment to be sexually exclusive, which has special significance in the relationship. However, it is not necessarily worse than other kinds of infidelity, and the context in which it takes place ought to be considered. I finish the paper by looking at how the hegemonic norm of monogamy makes infidelity both more likely and more difficult to deal with.
