Concepts contain rich structures that support flexible semantic cognition. These structures can be characterized by patterns of feature covariation: Certain features tend to cluster in the same items (e.g., "feathers," "wings," "can fly"). Existing computational models demonstrate how this kind of structure can be…

This report describes seven basic experiments designed to further elucidate the nature and function of two types of organization imposed by subjects in a free-recall type of memory task. The experiments involved verbal stimulus materials and employed college students as subjects. The two types of organization investigated were category clustering,…

The purpose of these four studies (two pilot studies and two experiments) was to investigate the effects of verbal processes and dimensional preferences in children's learning and transfer. Experiment I investigated the effect of verbal instructions upon motor responses. Discriminate verbal instructions produced statistically significant higher…

The role of imagery is assessed in verbal concept identification and evidence is found that some concepts can be coded as images. (Author/AM)

ELEVEN ENGLISH-SPANISH BILINGUAL COLLEGE STUDENTS PARTICIPATED IN A WORD-ASSOCIATION STUDY. EACH SUBJECT WAS PRESENTED 35 STIMULI IN EACH OF FOUR CONDITIONS--PRINTED ENGLISH WORDS FOR ENGLISH RESPONSES, PICTURES FOR ENGLISH RESPONSES, PRINTED SPANISH WORDS FOR SPANISH RESPONSES, AND PICTURES FOR SPANISH RESPONSES. THE SPANISH-PRINTED WORDS WERE…

This study assesses the effects of visual and verbal rehearsal on the problem solving efficiency of preschool children. The study examines the use of stimulus pretraining designed to induce verbal rehearsal and compares the effectiveness of induced verbal rehearsal with the effectiveness of induced visual rehearsal. Fifty-four middle class…

This study explores the instructional impact of using computer multimedia to integrate metaphorical verbal information into graphical representations of biotechnology concepts. The combination of text and graphics into a single metaphor makes concepts dual-coded, and therefore more comprehensible and memorable for the student. Visual stimuli help…
