The primary thrust of the present experiment was to examine the relative learning rate or capacity of hyperactive children on a laboratory learning task involving concept learning. (Author/RK)

Discusses the discrepancy between the conceptualization of reflection-impulsivity and its operationalization. In a study of 100 children, the separate contributions of latency and accuracy were evaluated. Data indicated that accuracy had important personality concomitants; latency was inconsequential.

A multitrait-multimethod design provided the basis for variable selection and analysis on the nature of cognitive impulsivity in natural classroom settings. Observational measures were developed for field dependence-independence, as well as for low- and high conceptual level to determine their ecological validity. They were designed to form an…

The main purpose of this study was to select some 7 1/2 to 8 year old subjects and to determine if there was a difference between those classified as impulsive and those classified as reflective in their ability to conserve length. (Author)
