According to Kagan's (1965) notion of the conceptual tempo, impulsive disposition, usually measured by visual discrimination with match-to-sample tasks, is characterized by shorter response times and frequent errors whereas longer response times and fewer errors designate reflective disposition. The present study examined the effect of training mentally retarded children's conceptual tempo on verbal tasks such as questionnaire items. It was predicted that training impulsive children in march-to-sample visual discrimination nrould increase reaction time and decrease contradictions or 'errors' on questio~aire items. Subjects were 23 (median age = 14 yr., mean IQ = 43) impulsive responders with no identifiable visual-perceptual difficulties, selected from 85 mentally retarded children who were tested with the Kagan's Matching Familiar Figures Test Preschool Form. Based on a double-median solit. those with short reaction time (below median of 27.3 sec.) and high errors (above median of 3.6) were designated as impulsives. Responding style in verbal task was measured by an 11-item questionnaire selected from the Yes-Saying Scale (Rosen, Floor, & Zisfein, 1974). Two parts of the questionnaire were stated in such a way that the statement in one part was the reverse of the other. A contradiction or 'error' was indicated by two Yes's or rwo No's. Subjects were randomly assigned to three groups: visual discrimination (n = 8). question-answering (n = 8), and no-treatment control (n = 7). Both visual discrimination and question-answering groups received nine sessions each lasting 30 min. on a bi-weekly basis, and these training sessions extended over 5 wk. The visual discrimination training followed Gurlanick's (1976) self-instructional model, whereas the questionanswering focused on listening carefully, answering slowly and clearly, requesting the question be repeated, and saying No or I don't know when necessary. The reaction times and errors on the Marching Familiar Figures Test and the questionnaire were compared among the groups by analysis of covariance using the pretest score as covariate. The results were: (a) The visual discrimination group tended to show less error and longer reaction time only on the Matching Familiar Figures Test, while the question-answering group tended to show the same pattern only on the questionnaire; however, only reaction time to the questionnaire (F2.10 = 3.55, p < .05) reached statistical significance, and (b) The Matching Familiar Figures Test correlated with the questionnaire .36 (n = 54, p < .01) on reaction time and .38 on error. These findings, based on a highly structured questionnaire, are similar to those of Kagan (.30 for boys, .38 for girls) who employed an open-ended interview.
