Abstract

Summary Twenty-three college students of both sexes were given the adult version of Kagan's Matching Familiar Figures Test; tests requiring them to draw a line and a circle slowly vs. rapidly; and a motor inhibition task in which they were instructed to press a telegraph key in response to tones presented in the presence of only particular light displays. Ss also rated themselves on a scale of impulsivity. Neither number of errors nor response latencies on the Matching Familiar Figures Test was significantly correlated with the other measures of impulsivity, but as expected, the two measures were correlated negatively (r = -.48) with each other. Self-ratings were unrelated to the other measures, but scores on the draw a line, draw a circle, and motor inhibition tasks were interrelated. These data do not support Messer's hypothesis that performance in the Matching Familiar Figures Test is correlated with performance on other tasks indexing impulsive behavior.
