The Group Assessment of Logical Thinking (GALT) instrument has been widely used to gather cross-cultural data regarding the acquisition of logical thinking skills in adolescent children. This study of West German adolescents using the instrument adds further comparative data regarding the development of logical thinking skills. Additional data…

This study attempted to develop, implement, and evaluate an experimental preschool education program based on Piaget's theory of cognitive development. A further goal was to examine Piaget's theoretical assumptions and postulated cognitive developmental trends for a 2-year period of the preoperational substage. A total of 48 3- to 5-year-olds…

This study tested the hypothesis that a 6-month, half-day program of enrichment in language and Piagetian sensorimotor skills tailored to the cognitive-developmental level of infants would accelerate the development of participating infants. The experimental population consisted of 16 12-month-old infants attending enrichment sessions at Syracuse…

The consistently inferior performance of economically disadvantaged children led to this study designed to investigate how cognitive development changes with age and how it is affected by previous life experience. Classification behavior and inferential thinking were the main concerns of the study. The measurement instrument was the Matrix Test, a…

This study reports various aspects of the analyses carried out on the longitudinal data reported in a previous study (PS 007 345) for determining the general growth patterns and growth velocity of mental and motor development. Preliminary analyses focused on the selection of the growth curve, its evaluation in the 208 individual cases, and the…

First and fifth graders participated in this assessment of ways in which differential experience with objects in a spatial array might establish relative landmarks within the array. Results suggest that different levels of experience can establish elements as relative landmarks in spatial memory. (Author/RWB)

Two experiments look at factors influencing the ways children construct an abstract representation of story structure that contains the characteristics described by story grammars. (RWB)

Investigates the metalinguistic ability of monolingual or bilingual children between five and nine years of age on two language tasks (grammaticality judgment and correction). (HOD)

Reports free and cued recall experiments in which a new model was used to obtain measurements of age changes in storage and retrieval. Participants were 7- and 11-year-olds. Findings concern (1) contributions of storage and retrieval to memory development; (2) effects of errors and successes on memorization; and (3) difficulty of storing and…

This study was designed to explore relations among reading skills, metareading, memory, and metamemory. Interactions among these skills were investigated as related to reading ability, operativity, and grade level. The effects of experience, operativity, and metacognition on reading and memory skills were discussed. (Author/DWH)

This study investigated the effects of an inductive reasoning training program on children's performance on intelligence test tasks, the range of transfer, the long-term effects of training over 4 months, and the effectiveness of group training. Participating were 47 third-grade children of average ability. The 23 children randomly assigned to the…

Surveys 30 studies involving 104 separate tests of the "similar structure hypothesis" which holds that, when nonorganically impaired retarded and nonretarded persons are similar in developmental level, they are also similar in the processes and concepts by which they reason. (Researchers distinguished between studies that excluded…

The effectiveness of computer aided instruction (CAI) is compared with that of videotaped instruction in the teaching of diacritical markings to postsecondary deaf students. Data indicate that cognitive skills were well taught by CAI in a short time without requiring teacher or student time in class. The TV version did not teach well. (CT)

Describes a cross-cultural comparative study of recall memory among children from two Guatemalan towns and one American city. (CM)
