In two experiments, 168 subjects aged 8-22 years performed visual search and memory search tasks (experiment 1) or memory search, mental rotation, analogical reasoning, and mental addition tasks (experiment 2). Increases with age in speeds of visual and memory search were described well by exponential functions. (SKC)

A study of 240 students in grades 4-10 found that fourth graders performed well on a proverb comprehension task involving contextual information, refuting earlier findings that preadolescents interpret proverbs literally. Performance was found to improve steadily through grade eight and was correlated to performance on a perceptual analogical…

Young, middle-age, and old adults ranked similarities of word pairs in a conditional rank-ordering task. Analyses of variance revealed an age-related decline in semantic processing but no such decline for elaboration. Older adults' retrieval was less compatible with initial processing than was the case for younger adults. (Author/ABB)

In testing conservation of number in preschool children using both equality and inequality; 3- and 4-year-olds tended to use an acquiescence response set while 5- and 6-year-olds responded in terms of relative length. (ST)

Study explores the preschool child's ability to operate on a cognitive level by testing his capacity to compare a concrete stimulus with some abstract concept. (Author/CB)

Study concerned with the effects of procedural differences on the classification of geometrical stimuli. (Author)

Study was designed to obtain cross-sectional data on the level of cognitive development of three age groups. (Author)

In three experiments, three- and four-and-a-half-year-old preschool children were tested on free and cued recall tasks in which semantic and contextual cues were manipulated. When context and target items were integrated experimentally at presentation, unrelated context cues improved recall. A developmental increase in the effectiveness of…

Suggests that aspects of children's early representational drawing ability may provide evidence for feature marking in nonlinguistic symbol systems. Reports results of a study of the drawings of kindergarten, second-, and fourth-grade children. (RH)

Chicano mothers were observed teaching their own five-year-old children. Field-independent mothers used inquiry and praise; field-dependent mothers used modeling. Trends suggest that the teaching strategies to which the child is exposed may influence which cognitive style the child develops. (Author/CP)

Animistic responding was generally unrelated to logical classification ability or to analytic cognitive style. Results which found high levels of animistic thinking beyond adolescence do not support Piagetian theory. Adults may respond animistically because of emotional attachments which they have formed to certain meaningful physical objects.…

In order to determine if there are developmental effects on information integration and dispositional attributions, 145 adolescents at two ages (13 and 18) were presented with information about hypothetical peers. (Author/MP)

This study sought to determine if age-related increases in memory for prose are, in part, due to deliberate mnemonic strategies and if older children use the high order relations in prose more efficiently than younger children. (HOD)
