Developmental research suggests that some of the mechanisms that underlie numerical cognition are present and functional in human infancy. To investigate these mechanisms and their developmental course, psychologists have turned to behavioral and electrophysiological methods using briefly presented displays. These methods, however, depend on the…

This paper reviews research on symbolic play gaps between children with and without language impairment (LI), arguing that these gaps should not be interpreted as demonstrative of marked deficits in general representational or specific symbolic play competence of children with LI. Frequent encroachment of language into testing procedures is cited…

Studies the processing of pictures and words as symbols. Shows that the superiority of pictures results from the fact that pictures are interpreted more quickly than words, but that after the interpretation is made, processing is the same. Also gives evidence that pictures and words are both processed in terms of linguistic codes rather than…

Sixty kindergarten, sixty second grade, and sixty fourth grade students performed several memory tasks under one of six conditions. The conditions differed as to the method of presentation of information. The study focused on developmental changes in children's use of verbal, nonverbal, and spatial-positional cues for memory.

The "symbol systems approach" to the study of computers in education that is outlined avoids the pitfalls of past media research--particularly research on the effects of television on children's learning and knowledge--and asserts that media can be usefully distinguished in terms of the symbol systems they present and the kinds of…

In a study of mathematics learning, taking a rule-oriented approach, students were taught to trade objects of type A for objects of types B and C. Children ranging from ages 7 to 9 were given rules for converting A to B and B to C and were then presented with the task of converting A to C. Of the 30, 6 succeeded. Of the 24 who failed, half were…

This study was conducted to determine whether the filmic coding elements of split screen, slow motion, generated line cues, the zoom of a camera, and rotation could aid in the development of the Euclidean space concepts of horizontality and verticality, and to explore presence and development of spatial skills involving these two concepts in…

Sixty-six goals, mostly involving symbolic representation and cognitive processes, were evaluated to indicate those aspects of the summative research on Sesame Street that were bases for generalizing about research into the development of preschoolers. Unintended and intended outcomes were investigated as well as the program's effectiveness for…
