Judgments of risk frequencies: tests of possible cognitive mechanisms

How do people judge which of 2 risks claims more lives per year? The authors specified 4 candidate mechanisms and tested them against people's judgments in 3 risk environments. Two mechanisms, availability by recall and regressed frequency, conformed best to people's choices. The same mechanisms also accounted well for the mapping accuracy of estimates of absolute risk frequencies. Their nearly indistinguishable level of performance is remarkable given their different assumptions about the underlying cognitive processes and the fact that they give rise to different expectations regarding the accuracy of people's inferences. The authors discuss this seeming paradox, the lack of impact of financial incentives on judgmental accuracy, and the dominant interpretation of inaccurate inferences in terms of biased information processing.     

The children in the community study of developmental course of personality disorder

The Children in the Community (CIC) Study is an ongoing investigation of the course of psychiatric disorders including personality disorders (PDs) in an epidemiological sample of about 800 youths. In addition to tracking developmental trajectories over 20 years from adolescence into adulthood, the CIC Study has used prospective data to investigate early risks for Axis II disorders and symptoms (including both environmental factors and early characteristics), implications of comorbidity with Axis I disorders, and associated negative prognostic risk of adolescent PDs into adulthood. The substantial independent impact of PD on subsequent Axis I disorders, suicide attempts, violent and criminal behavior, interpersonal conflict, and other problematic adult outcomes confirms the importance of attention to these problems when they manifest in early adolescence. The implications of study findings for potential changes in the DSM are discussed.     

The Impact of Physical Maltreatment History on the Adolescent Mother–Infant Relationship: Mediating and Moderating Effects During the Transition to Early Parenthood

Using attachment theory as a framework, this paper examines how pregnant adolescents' experiences of physical maltreatment during childhood influence the subsequent mother-infant relationship in 203 low-income adolescents followed from the 3rd trimester of pregnancy through the 1st year of parenthood. The relation between physical maltreatment history and early difficulty in the mother-infant relationship was mediated by adolescents' evaluations of the relationship with their primary caretaker and the feelings they associated with motherhood measured prior to childbirth. In addition, a supportive romantic relationship during pregnancy acted as a protective factor by moderating the impact of maltreatment history on the quality of the subsequent mother-infant relationship. Findings support the importance of assessments and interventions that consider the social context and relational history of pregnant and parenting adolescents.     

Who takes the most revenge? Individual differences in negative reciprocity norm endorsement

The authors report that beliefs favoring the reciprocation of unfavorable treatment form a unitary factor that is distinct from beliefs favoring the reciprocation of favorable treatment. Individual differences in endorsement of this negative reciprocity norm were related to (a) beliefs that people are generally malevolent; (b) inclination toward anger in everyday life; (c) anger, disagreement, and ridicule directed toward a new acquaintance who treated participants unfavorably; and (d) reduced anxiety, positive emotional engagement, and encouragement of a new acquaintance who treated participants favorably. These findings suggest that individual differences in endorsement of the negative norm of reciprocity influence the extent of vengeance.     

Adolescent personality disorders and conflict with romantic partners during the transition to adulthood

Longitudinal data were used to investigate the association of adolescent personality disorders with conflict between romantic partners during the transition to adulthood (i.e., age 17 to 27). Findings indicated that adolescent personality disorders (PDs) assessed at mean age 16 were associated with subsequent elevated partner conflict. Cluster B PD was associated with sustained elevations in partner conflict throughout the transition to adulthood. Cluster A and C PDs were associated with elevated partner conflict before age 23. Paranoid, schizoid, schizotypal, borderline, narcissistic, and obsessive-compulsive PD symptoms were independently associated with sustained elevations in partner conflict.

Twenty years of student sexual behavior: subcultural adaptations to a changing health environment

This twenty-year study analyzes changes in sexual behavior among students at Okanagan University College in British Columbia, Canada. Surveys conducted in 1980, 1990, and 2000 reveal a steady increase in safer sexual practices. Most students now question potential partners about their past, use condoms with a new sexual partner, and maintain fairly long-term monogamous relationships. Three sexual subcultures continue to coexist in fairly stable proportions: celibacy (about 30%), monogamy (about 60%), and free experimentation (about 10%). Each subculture has created its own response to the danger of HIV/AIDS: celibates exaggerate the danger they face, monogamists rely on love and fidelity for protection, and free experimenters have increased their use of condoms. While romantic feelings lead many monogamous couples to abandon condoms without objective HIV/AIDS knowledge, free experimenters still face the highest risk. Although they now use condoms more than half the time, their lifestyle, which involves multiple partners, risky sexual acts, and frequent drug and/or alcohol use, clearly remains dangerous. The persistence of distinct subcultures has implications for health education programs, which would be most effective if based on key values held by specific target groups.     

Executive function and theory of mind: stability and prediction from ages 2 to 3

Several studies have demonstrated a relation between executive functioning (EF) and theory of mind (ToM) in preschoolers, yet the developmental course of this relation remains unknown. Longitudinal stability and EF-ToM relations were examined in 81 children at 24 and 39 months. At Time 1, EF was unrelated to behavioral measures of ToM but was significantly related to parent report of children's internal-state language, independent of vocabulary size. At Time 2, behavioral batteries of EF and ToM were significantly related (r=.50, p<.01). Furthermore, EF (Time 1) significantly predicted ToM (Time 2), independent of several controls. A reciprocal relation (internal-state language --> EF at Time 2) was nonsignificant with the controls included. Individual differences in EF were relatively stable.
