Three source-memory experiments were conducted with Spanish-English bilinguals and monolingual English speakers matched on age, education, nonverbal cognitive ability and socioeconomic status. Bilingual language proficiency and dominance were assessed using standardized objective measures. In Experiment 1, source was manipulated visuo-spatially,…

Two studies of 7-year-olds and college students tested the hypothesis of a developmental difference in the degree to which subjects' memory performance was controlled by categorical properties vs. specific instance properties of test items. (GO)

The purpose of the two experiments was to assess the effects of two levels of stimulus redundancy and three levels of irrelevant visual stimulation on performance in a successive discrimination task and a reproduction task. The results indicate that increases in redundancy facilitated performance in the reproduction task but had no appreciable…

This document describes a project which was designed (1) to develop a program to teach concepts to young children, and (2) to pilot test the program using college students as teachers of Appalachian children. The instructional program was composed of a series of visual discrimination problems in which the child must discriminate the correct from…

A sorting task was used to define concepts held by 120 children (4, 5, and 18 years old) as available and nonavailable. These concepts were then used at the appropriate age levels in a discrimination-learning task. After learning the discrimination, either a reversal or half-reversal shift was required. (MS)

Three experiments tested the application to art of an hypothesis from the concept attainment literature, that conceptual learning is enhanced by providing multiple examples prior to test trials. Subjects were given discrimination tasks involving surrealistic and non-surrealistic paintings. The feature abstraction model proved inadequate in this…
