This study was concerned with evaluating the effects of incentive-related, transient anxiety on discrimination reaction time in terms of task difficulty. Ss were 472 Mobile, Alabama school children equally representing Negro and white races and the fourth, seventh, and tenth grades. Results of repeated measures analysis of variance indicated that, although the level of difficulty of the discrimination task is significantly related to speed of performance, there is no simple relationship between anxiety and task difficulty for either white or Negro Ss.
