Assessed developmental trends in competency to stand trial in a study of incarcerated and nonincarcerated adolescents (N=52) and adults (N=19). Results indicated that competency to stand trial does increase through the adolescent years, but even older adolescents received lower scores on a competency measure than did adults. (JAC)

Reviews research on children's ability to remember events in relation to that of adults. Concludes that age interacts with other factors, including language and the relative development of knowledge structures, to determine suggestibility. Suggests that children's memories may at times be less easily influenced than adults' memories. (KH)

A study involving 23 blind students (6-12 years old) revealed that age at onset of blindness did not appear to be critical in mastery of space concepts. One-third of the Ss exhibited atypical spatial development, g mastering relative positions of left and right before mirror-image orientation. (Author/CL)

Thirty-five children who had participated in a study of mastery motivation at one year of age were reevaluated at 3.5 years. Findings differed for boys and girls and indicated that a wide range of behaviors in the cognitive-motivational domain must be examined to find developmental continuities. (Author/CB)

Elementary school children were tested individually on their learning of mathematics and on Piagetian tests of concrete operations. Younger children were found to be inferior to older children in their success on learning tasks. (ST)

A study of developmental aspects of selective attention and task-related strategies of attention in 2nd and 6th graders. Age differences were found and interpreted as reflecting the development of flexible as well as selective attention strategies. (DP)

Results are discussed in terms of cognitive growth, the psychoanalytic notion of ambivalence, the role of stimulus context in eliciting laughter or fear, and a possible adaptive, stimulus-maintaining function of laughter. (Authors)

Study concerned with the mechanisms in terms of which the developmental transformation from one cognitive structure to another occurs. (Author)

An abstract of a study done during doctoral work (Temple University, Philadelphia, Pennsylvania). (RJ)

Level of cognitive development was not significantly related to humor appreciation for either novelty or incongruity humor in 30 boys at each of three age levels: 5, 7, and 9. (WY)

Investigates the relative roles of positive and negative cue retention on oddity transfer, and seeks to learn how these roles change with age and practice. Age range studied is from 3 to 7 years old. (MH)

Reports that form matching increased with age both in number of subjects with reliable preferences and in strength of preferences, but that at all ages form matches predominated. (Author/DR)

The degree of reality perception of cartoon and human-fantasy televised episodes was measured in four- and five-year-olds. Five-year-olds had a more mature reality perception than four-year-olds. Only five-year-olds had a more mature reality perception of cartoon than of human fantasy episodes. (Author/RD)

Aims to develop new procedures to collect and analyze data pertaining to spatial development, to explicate a neo-Piagetian model within which these data can be examined, and to assess the validity of this model in tasks requiring perceptual skills and/or rotation (perspective) skills. (RH)
