Examining memory for heterosexual college students' sexual experiences using an electronic mail diary.

To examine memory for sexual expenences, the authors asked 37 sexually active, nonmonogamous, heterosexual college students to complete an e-mail diary every day for 1 month. The diary contained questions about their sexual behaviors. Six to 12 months later, they returned for a surprise memory test, which contained questions about their sexual experiences from the diary phase. They were asked about their sexual partners, the types of sexual experiences they had, and condom use. Participants underreported the number of partners they had, but they overreported both sexual experiences and condom use. The results have implications for both sexual health educators and for people who engage in high-risk sexual behaviors.     

Sex differences in developmental trends of suicide ideation, plans, and attempts among European American adolescents

Although suicide ideation, plans, and attempts increase during adolescence, it remains unclear whether boys' and girls' risk for these outcomes peaks at different ages. We used longitudinal categorical data (never, once, 2+ times) from the Family Transitions Project (N = 1,248 rural European Americans, ages 11-19) to investigate whether yearly prevalence rates of adolescent suicidal episodes follow different patterns by sex. Multiple-group growth models revealed that peak levels of past-year ideation and plans occurred during mid adolescence for girls, but slowly increased through late adolescence for boys. We found that prevalence patterns for attempts were very similar for boys and girls, with both increasing through mid adolescence and then declining, although girls' risk declined slightly more rapidly. This information may help alert gatekeepers to developmental periods during which boys and girls are particularly vulnerable to suicide-related experiences, and also may help inform the timing of preventive efforts.     

Sustained withdrawal behavior in clinic‐referred and nonreferred infants

To examine the relations between infants' sustained withdrawal behavior and children's mental health status and maternal and child relational behavior, 36 clinic‐referred and 43 control infants were evaluated. Families were visited at home, mother‐child free play and feeding interactions were videotaped, and mothers completed self‐report measures. Interactions were coded for sustained withdrawal using the Alarm Distress Baby Scale (ADBB; Guedeney and Fermanian, 2001) and for global relational patterns with the Coding of Interactive Behavior (CIB; Feldman, 1998). Higher ADBB scores were found for the referred group, with many infants (38.9% ) scoring above the clinical cutoff (vs. 11.6% in the control group). More negative relational patterns were found for the withdrawn group in terms of higher maternal intrusiveness, lower reciprocity, and lower child involvement. Associations were found between maternal and child behavior during play and feeding and child sustained withdrawal behavior at play. Sustained withdrawal also was associated with unpredictable child temperament and lower sense of parental self‐efficacy. Maternal depressive symptoms were higher in the referred group and correlated with maternal and child relational patterns. The findings contribute to the construct and discriminant validity of the CIB and the ADBB coding systems, and suggest that sustained withdrawal may serve as a risk indicator for early socioemotional disorders.     

The Structure of Emotion

ABSTRACT— One common point of debate in the study of emotion is whether the basic, irreducible elements of emotional life are discrete emotion categories, such as anger , fear , sadness , and so on, or dimensions such as approach and avoidance . Resolving this debate will identify the basic building blocks of emotional life that are the most appropriate targets of scientific inquiry. In this paper, we briefly review meta-analytic work on the neuroimaging of emotion and examine its potential for identifying "natural kinds" of emotion in the brain. We outline criteria for identifying such natural kinds, summarize the evidence to date on category and dimensional approaches, and suggest ways in which neuroimaging studies could more directly address fundamental questions about the nature of emotion.
