Inhibiting children's memory of an interactive event: the effectiveness of a cover‐up

Children are generally more susceptible than adults to suggestive interview techniques. Children's memories of an event can be altered and added to by presenting post‐event information (PEI). What is not known is whether embedding silence about a particular scene within the PEI makes that scene less likely to be reported. Children aged 5–6 years made cakes with an agent ‘Mrs Flour’. The following day they received PEI in which a target scene from the original event was omitted, resulting in children reporting the target scene significantly less often than did controls (control= 57% and omit= 23% correct responses). There was direct evidence from the children's language that the omission led to a detriment in memory for the original scene itself. Allowing children to draw during the interview did not reduce the effect. Implications are discussed in terms of child victims and witnesses particularly regarding child sexual abuse.

THE WOMEN'S STUDIES EXPERIENCE

This study included 212 women and 38 men students from nine women's studies classes and 101 women and 35 men from nine non-women's studies classes. At pretesting and posttesting students completed the Performance Self-Esteem Scale (PSES) and measures of their educational and job certainty and motivation. Comparison students were similar to women's studies students in having a woman teacher and having an interest in the women's studies curriculum. At posttesting women's studies students showed greater gains in PSES scores ( p < .01) and in job motivation and job certainty ( p < .01) than did the comparison students. The results support the value of women's studies for men as well as women students.     

The Ability/Performance Dimension of Self-esteem: Implications for Women's Achievement Behavior

A 33-item measure, the Performance-Self-Esteem Scale (PSES), was developed to tap self-evaluations of ability and performance. Evidence from four samples of undergraduates (a total of 224 women and 236 men) indicate that the PSES measures a separate, distinct dimension of self-esteem. As predicted, undergraduate males scored higher on the scale than undergraduate women (p <.003), although this difference was significant for juniors and seniors only. Implications for research related to women's achievement-related behaviors and the college experience are considered.     

Pregnancy-specific stress, prenatal health behaviors, and birth outcomes

OBJECTIVE: Stress in pregnancy predicts earlier birth and lower birth weight. The authors investigated whether pregnancy-specific stress contributes uniquely to birth outcomes compared with general stress, and whether prenatal health behaviors explain this association. DESIGN: Three structured prenatal interviews (N = 279) assessing state anxiety, perceived stress, life events, pregnancy-specific stress, and health behaviors. MAIN OUTCOME MEASURES: Gestational age at delivery, birth weight, preterm delivery (<37 weeks), and low birth weight (<2,500 g). RESULTS: A latent pregnancy-specific stress factor predicted birth outcomes better than latent factors representing state anxiety, perceived stress, or life event stress, and than a latent factor constructed from all stress measures. Controlling for obstetric risk, pregnancy-specific stress was associated with smoking, caffeine consumption, and unhealthy eating, and inversely associated with healthy eating, vitamin use, exercise, and gestational age at delivery. Cigarette smoking predicted lower birth weight. Clinically-defined birth outcomes were predicted by cigarette smoking and pregnancy-specific stress. CONCLUSION: Pregnancy-specific stress contributed directly to preterm delivery and indirectly to low birth weight through its association with smoking. Pregnancy-specific stress may be a more powerful contributor to birth outcomes than general stress.     

The Development and Testing of a New Version of the Cognitive Reflection Test Applying Item Response Theory (IRT)

The cognitive reflection test (CRT) is a short measure of a person's ability to resist intuitive response tendencies and to produce a normatively correct response, which is based on effortful reasoning. Although the CRT is a very popular measure, its psychometric properties have not been extensively investigated. A major limitation of the CRT is the difficulty of the items, which can lead to floor effects in populations other than highly educated adults. The present study aimed at investigating the psychometric properties of the CRT applying item response theory analyses (a two‐parameter logistic model) and at developing a new version of the scale (the CRT‐long), which is appropriate for participants with both lower and higher levels of cognitive reflection. The results demonstrated the good psychometric properties of the original, as well as the new scale. The validity of the new scale was also assessed by measuring correlations with various indicators of intelligence, numeracy, reasoning and decision‐making skills, and thinking dispositions. Moreover, we present evidence for the suitability of the new scale to be used with developmental samples. Finally, by comparing the performance of adolescents and young adults on the CRT and CRT‐long, we report the first investigation into the development of cognitive reflection.

Online usage of theory of mind continues to develop in late adolescence

The development of theory of mind use was investigated by giving a computerized task to 177 female participants divided into five age groups: Child I (7.3–9.7 years); Child II (9.8–11.4); Adolescent I (11.5–13.9); Adolescent II (14.0–17.7); Adults (19.1–27.5). Participants viewed a set of shelves containing objects, which they were instructed to move by a ‘director’ who could see some but not all of the objects. Correct interpretation of critical instructions required participants to use the director’s perspective and only move objects that the director could see. In a control condition, participants were asked to ignore objects in slots with a grey background. Accuracy improved similarly in both conditions between Child I and Adolescent II. However, while performance of the Adolescent II and Adult groups did not differ in the control condition, the Adolescent II group made more errors than the adults in the experimental condition. These results suggest that theory of mind use improves between late adolescence and adulthood. Thus, while theory of mind tasks are passed by age 4, these data indicate that the interaction between theory of mind and executive functions continues to develop in late adolescence.     

The Critical Mediating Role of Social Encouragement for Science Motivation and Confidence Among High School Girls and Boys1

Previous research has identified student status variables (gender, ability, and parent education level) and social influence variables (encouragement from family, teachers, and peers) as predictors of science attitudes. The present study tested the extent to which social encouragement mediates the relation between status variables and science motivation and confidence. In a sample of 184 senior high school students, social encouragement was a stronger predictor of science attitudes than status variables and mediated 72% of the variance in attitudes predicted by status variables. Encouragement from family, encouragement from teachers, and encouragement from peers were each independent predictors of science attitudes. The findings provide strong evidence of the critical importance of encouragement from social agents in the development of adolescents' motivation and confidence to achieve in science.
