Adolescents engage in more risky behavior when they are with peers and show, on average, heightened susceptibility to peer influence relative to children and adults. However, individual differences in susceptibility to peer influence are not well understood. The current study examined whether the effect of peers on adolescents' risky decision…

This research demonstrates significant but moderate association among 4 methods of measuring other-centeredness, including behavioral, cognitive, valuative, and peer-rating measures. (Authors)

A new technique for determining children's subjective organization of speech is described. The technique required subjects to memorize a target sentence, and then to respond with the second next word when the sentence was interrupted by the sound of a tone. (MP)

This study first found that an adaptation of the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children exhibited construct validity and test-retest reliability in assessing preschool children's sensitivity to age-related differences in peers' developmental abilities. Second, children with disabilities were viewed as less…

This paper reports on the development and validation of an instrument for recording haptic exploratory behavior through detailed examination of exploratory search strategies of young children. Individual differences within age level were investigated, as well as the extent to which information processing capabilities for haptic perception are…

This paper discusses research exploring the performance factors involved in studies which test for formal operations. It is suggested that several previous studies dealing with formal operations confound performance and competence in determining the extent of subjects' formal operations schemata. Factors which might account for performance…

Background: There is considerable interest in differences in students' approaches to learning, particularly in the difference between "deep" approaches (characterized by contextualization, critical review and recognition of the value of the content) and "surface" approaches (characterized by rote learning for functional…

One of the most noticeable changes to the university student profile over the last decade is the increasing number of mature-age students.

A number of questions associated with development and the stability of self concept were examined. These include: (1) the…

Recent investigations have demonstrated greater variance in change in intellectual performance between different generations or age groups than is true for generalized developmental change across chronological age. Such findings have led to a careful investigation of certain environmental factors which might account for such change. A new…

The theoretical work on attachment behavior by John Bowlby and Mary Ainsworth spawned one of the broadest, most creative lines of research in twentieth century psychology.
