Two studies assessed the ability of two groups of preschool children (ages two to four and three to five years, respectively) to label and categorize age groups on the basis of photographs and dolls representing the life span. Results indicated age and sex differences. (Author/CI)

Formal and familiar materials were used to test Piagetian classification and formal operational abilities in two groups of educated adults: one group aged 30-38 and the other aged 57-82 years. Subjects did not show mastery of the tasks. Results suggest a new model of cognitive lifespan development. (Author/MS)

Taken together, these five studies using structurally different kinds of conceptual problems provide evidence for qualitative developmental and cultural differences in classificatory behavior. (Authors/CB)

Recommends that one begin by ignoring the overall unemployment rate and concentrate on some particular groups with special problems in making employment policies. (DM)

Results indicates that awareness of the facilitative effect of categorization on recall increases with age, particularly during the early grade-school years. (Author)

Study concerned with the question of why older children remember more in categorized free recall. (Authors/MB)

Examines the issue of object sorting in early infancy. Forty-eight infants at 6, 9, and 12 months were presented with eight sets of small, manipulable objects. At six months, selective manipulation was absent; at nine months, 94 percent of the infants sequentially touched similar objects and at 12 months 100 percent did so. (Author/DB)

Confirms the previous suggestion that I-level and Verbal IQ are significantly related--for males, but not for females. The effect among males disappeared when age was introduced as a variable. Two of the variables, age and Verbal IQ, unexpectedly related strongly. (Author)

Attempted to determine whether 170 third and sixth graders would benefit from the simultaneous use of 2 mnemonic strategies. Findings suggest that categorical sorting and active rehearsal combine to facilitate recall performance. (RJC)

Perceptual categorization and consistency of synthesized speech was studied with 10 normally articulating children (aged six-seven), 10 children producing /r/ misarticulations (aged five-eight), and 18 adults. Results revealed that variability in stimulus response was influenced primarily by subjects' productive ability, whereas differences in…

Four experiments determined that kindergartners' and second graders' inductions are sensitive to the similarity between premise and conclusion categories. Second graders' inductions are sensitive to the similarity of a premise category to a higher order category that includes the premise and conclusion categories. (BC)

A study investigated the communication strategies used by successful and less successful early French immersion learners by analysis of the use of 10 specific communication strategies. Results show effective communicators used virtually all strategies, with more achievement than reduction strategies; less effective communicators used fewer…

A study involving elementary school students in three age groups examined two explanations for the finding that young children tend to classify objects according to similarity relations, whereas adults emphasize dimensional structure. Results countered the view that children perceive objects according to a more primitive holistic structure. (RH)

Fears profiles among children and adolescents were explored using the Fear Survey Schedule for Children-American version (FSSC-AM; J.J. Burnham, 1995, 2005). Eight cluster profiles were identified via multistage Euclidean grouping and supported by homogeneity coefficients and replication. Four clusters reflected overall level of fears (i.e., very…
