Social relationships and ambulatory blood pressure: structural and qualitative predictors of cardiovascular function during everyday social interactions.

Healthy normotensive men and women (N = 102) underwent a 3-day ambulatory blood pressure (BP) assessment in which a BP reading was taken 5 min into each social interaction. After each interaction, participants completed a diary that included structural categorization of the relationship and ratings of the quality of the relationship with the interaction partner. Random regression analyses revealed that interactions with family members and spouses were associated with lower ambulatory BP. Interactions with ambivalent network members (characterized by both positive and negative feelings) were associated with the highest ambulatory systolic BP, an effect that was independent of the familial effects on BP. Although there were psychological correlates associated with both structural and functional aspects of relationships, no evidence was found that these mediated the primary findings involving ambulatory BP. These data highlight the influence of both structural and qualitative aspects of relationships on ambulatory BP and possibly health.     

Models of competence in solving physics problems

We describe a set of two computer-implemented models that solve physics problems in ways characteristic of more and less competent human solvers. The main features accounting for different competences are differences in strategy for selecting physics principles, and differences in the degree of automation in the process of applying a single principle. The models provide a good account of the order in which principles are applied by human solvers working problems in kinematics and dynamics. They also are sufficiently flexible to allow easy extension to several related domains of physics problems.     

THE IMPACT OF I/T/A ON LOW‐LEVEL READERS IN THE JUNIOR HIGH SCHOOL

The Initial Teaching Alphabet was contrasted with traditional orthography in remediation classes for slow readers at the junior high school level. Using the Iowa Test scales as the measure of achievement, the Initial Teaching Alphabet group demonstrated statistically superior gains. Differences in motivation and attitude were ruled out as major contributors. The Initial Teaching Alphabet potential as a remediation technique for higher grade levels appears to be dependent upon curriculum standardization and teacher preparation.     

GENDER'S ROLE IN RESPONSES TO INFERTILITY

Infertility is a major life stressor that affects approximately 10% of U.S. married couples. Infertile women and men have reported experiencing depression, helplessness, and marital strain. Given U.S. society's emphasis on women's role as mothers, it has been suggested that women's lives are more disrupted by infertility than those of men. This hypothesis was supported in a survey of 185 infertile couples and 90 presumed fertile couples. Infertile wives, as compared to their husbands, perceived their fertility problem as more stressful, felt more responsible for and in control of their infertility, and engaged in more problem-focused coping. Infertile husbands experienced more home life stress and lower home life performance than did their wives. These differences were not found for presumed fertile couples. Both infertile and presumed fertile wives experienced more depression, more sexual dissatisfaction, and lower self-esteem than did their husbands. Theoretical and counseling implications of these findings are discussed.     

Asking Adolescents to Explain Discrepancies in Self-Reported Suicidality

We present a typology of adolescents' most common explanations for discrepant reporting of suicidal behavior. Forty-eight adolescents provided attempt histories by completing a self-report measure of suicidality. A select number of items were subsequently readministered (average interval = 5 days) using a semistructured interview format. Discrepancies in reporting were found among 50% of the sample. Adolescents were also asked to clarify, using an open-ended format, what might have accounted for a particular discrepancy. Based on these responses, seven mutually exclusive and exhaustive categories were derived. High rates of interrater agreement indicated that these categories were reliable.
