34 boys and 30 girls in Grades 2 and 3 were given a measure of conceptual tempo (the Design Recall Test) and a task requiring them to toss poker chips at a target, estimating the number on target (a measure of level of aspiration). Messer's hypothesis that impulsive children, unlike reflective ones, are anxious about their ability to perform well on such sensorimotor tasks, predicts differences between tempo groups on the level of aspiration task. The results indicated that performance on the Design Recall Test was unrelated to any of the measures from the level of aspiration task (latency, accuracy, and self-estimates of accuracy), even when subjects in the two remaining latency × errors cells were included in analyses. Thus consistent with results of most previous studies, no support was obtained for Messer's hypothesis.
