Examined contributions of physical attractiveness and physical effectiveness to self-esteem among adolescents in grades 7, 9, and 11, and college freshmen. Both attractiveness and effectiveness were significantly related to self-esteem of males and females. Attractiveness and effectiveness did not appear to be differentially important to…

Describes two studies conducted in the United Kingdom that tested the effectiveness of flowcharts versus contingency statements for solving complex problems, one with secondary school students and one with senior citizens. Two measures of effectiveness are considered, speed and accuracy; and the effects of practice upon using the materials are…

Two studies explored factors relating to children's willingness to perform tasks that are not traditional to their gender. More untraditional behavior was elicited with male than with female examiners. Mechanisms that may underlie this effect are discussed. (BC)

Examines perceptions of adults compared with preschool children in assuming object permanence or discontinuity of existence when an object is removed from their immediate perceptual field. Results showed that a belief in the possibility of the discontinuity of material objects is not unique to the minds of preschool children but can also be…

Researchers assessed geographic literacy in 300 college students, comparing a variety of demographic and academic factors to levels of geographic literacy. Findings reveal weak relationships between some of the academic factors and geographic competence. However, very powerful relationships are evident between geographic literacy and race, age,…

Used stepwise discriminant analysis on calibration sample (n=135) of juvenile inpatients to determine which variables best distinguished violent inpatients. Cross-validated model on 123 subjects. Violent subjects were more likely to be younger males with family history of criminal behavior and extensive discord. Violent subjects showed differences…

Examined Israeli adolescents' responses to impending unconventional warfare by administering Nuclear Threat Index to 269 junior high school students 2 months prior to Persian Gulf War. Younger adolescents and females reported more activity, pessimistic thoughts, and concerns than older adolescents and males, respectively; and "internal"…

Recent research supports Vygotsky's "zone of proximal development" theory; children receiving peer assistance can stretch their learning beyond their individual accomplishment. A study of a multiage classroom revealed three strategies used by children working together to solve math problems--modeling, tutoring, and pairing/sharing…

Interviewed 62 families that had recently placed their mentally retarded children about their experiences. Placements generally followed gradual build-up of child-related stress. Parents reported high satisfaction with placement and positive family adaptation following placement. Family experiences generally were not related to child's age, level…

Using a 1987 sample of 526 undergraduates, this study examines changes in student alcohol use, alcohol abuse, and attitudes toward drinking over their college careers. The maturation of attitude and behavior observed in females was not seen in males, for whom college may represent a period of protracted adolescence. (SLD)

Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)

Explored possible link between development of moral reasoning/behavior and metacognition. Examined awareness of moral processes involved in moral reasoning and behavior in 139 adolescents in grades 7, 9, and 12. Found number of significant moral metacognition-reasoning-behavior correlations. Findings support notion that specific types of metamoral…

Reports on a survey of high school students in two school systems. Information was obtained on patterns of alcohol and other drug (AOD) use, indices of AOD use for grade and gender, and relationships of indices to individual, family, and social competence/adjustment risk factors. (SM)

A study used the Three-Interval Forced-Choice Test of Speech Pattern Contrast Perception (THRIFT) to examine sensory-level speech-perception performance under the input modalities of hearing alone, speech-reading alone, and the two combined in 44 children (ages 5-10). Within each condition there were significant influences of age on performance…

Three studies explored age changes and individual differences in preschoolers' sustained attention in different contexts. Found that changes occurred earlier for play and television viewing than for reaction time tasks. Results suggest that children have stable tendencies to sustain attention but that attention varies with task demands and…
