From a co-operative education class in an urban high school, 16 adolescent males were identified as impulsive and as high-risk based on their performance on the Matching Familiar Figures test and the advice of teachers and counselors. Students participated in 12 to 15 videotaped group problem-solving sessions (20-25 minutes in length) over a period of four months. Attrition precluded any attempt at generalizations from the results. However, two dependent measures of change in impulsive behavior were in the predicted direction and provided limited support that the enhancement of verbal mediation and attentional behaviors through self-instruction training will reduce the incidence of behaviors associated with cognitive impulsivity among high-risk adolescent male students. This document provides an extensive literature review presenting evidence of a strong link between impulsive thinking styles and forms of delinquency and other maladaptive behavior. A bibliography of 96 citations dated from 1950 to 1982 is included. (PN)
