Cognitive development during each of the major stages identified by Piaget is characterized by abilities to solve progressively more complex tasks (e.g., changes in the object concept during the sensori-motor stage, and in conservation of amount, weight, and volume during the concrete operational stage). Several theorists have suggested that these…

A preliminary study was conducted to identify the precipitating conditions and strategies used for vocabulary acquisition and to relate these findings to one theory of elementary and post-elementary cognitive development. Twenty-six college seniors were asked three questions regarding precipitating conditions and strategies used for vocabulary…

In addition to the important role of memory strategies in mediating age changes in recall performance, it is clear that the permanent memory system (or information available in the knowledge base) exerts a significant influence on the acquisition and retention of information. Age changes in memory performance will be fully understood only through…

The effect of playing a logic game, Master Mind, on student learning in physics was examined in this study. An experimental group of 16 Electronics Engineering Technology students played the game during class one hour per week for seven weeks. A control group of nineteen students took the course without playing the logic game. Results showed that…

In order to determine whether there are developmental differences in the handling of the modality attribute 32 children from each of grades two and six and 32 college students were presented with a video-taped mixed-modality list of 32 first grade words. Subjects were asked to recall the words, to identify the presentation modality of each word on…

The paper reviews the literature and proposes a study on how nonlanguage deaf/blind children (ages 2 to 14) match and classify, the age at which the skills are reached, and the role of language in the process. The theories of J. Piaget and J. Bruner on the importance of language in stage development are explored. The Ss would be matched for age…

The purpose of this study was to investigate in children from ages 4 to 10 the development of logical propositions and to determine whether or not there is a developmental sequence in children's ability to supply missing elements of syllogisms. A specially designed instrument, consisting of an equal number of items with missing major premises,…

In this study of the development of logical propositions in children, two hypotheses were tested: (1) There will be a significant difference in the scores and proportions of students from age level to age level in the ability to supply missing elements of syllogisms, and (2) There will be a hierarchy of difficulty for all subjects in supplying…

This study examines the development of children's concepts of illness in light of Piagetian findings regarding the ontogenesis of causal relations. The Concept of Illness protocol was administered to 72 3-, 7-, and 11-year-old children; 24 from each age group. Children were interviewed individually in a school setting. Raters assigned subjects'…

Described are procedures used to assess reasoning in congenitally blind students. It is explained that the Piagetian Battery of Reasoning Assessments for concrete and formal or abstract thought measures the following basic abilities: reversability of thought, classifacatory thought, spatial orientation, and mental imagery.

This paper discusses research on age related aspects of children's processing and comprehension of the narrative content of family oriented television programs. In one study, the temporal integration necessary to make inferences about audiovisually presented information was examined in 254 second, fifth and eighth grade children. Subjects were…

This paper examines the interrelationship between children's acquisition and use of symbols and the development of imaginative play. The paper focuses on the use of pretend play as an expression of the child's capacity for symbolic functioning and as an index of intellectual development. The first section of the paper reviews developmental changes…

This paper reports two experiments which examined processes involved in children's ability to solve class inclusion problems of the form, "Are there more A' (subclass) or more A (class)?" In the first experiment a total of 216 children in age groups 5, 7 and 9 years were placed in three conditions which were designed to distinguish…

The purpose of this study was to investigate the development of organizational processes for both verbal and spatial stimulus materials within an information processing framework. Children in grades 2 and 4 and adults were tested for their ability to report letter strings reflecting various orders of approximation to English and various dot…
