This study investigated the effects of a 10-mo. endurance-training program (running) on speeded psychometric skills. On a weekly basis the experimental group of 36 subjects participated in one supervised and three unsupervised training sessions. The control group of 22 subjects engaged in no structural training activities during this period. Subjects' performance on a simple reaction-time task, a choice reaction-time task, and a letter-recognition task was assessed before and after the training intervention. Analysis indicated that a 20% improvement in aerobic fitness in the trained group was not accompanied by a significant improvement in psychometric performance. This result is discussed in terms of the relationship between aerobic fitness and cognitive performance. It is concluded that improved physical fitness is not necessarily accompanied by improved perceptual-motor skills.

Related Stress

Two tasks (simple and choice reaction time) were examined while varying three types of stressors (shock, threat of shock, and noise) and the stressor task relationship (i.e., task-related stress, task-unrelated stress, and no-stress). Four specific hypotheses were tested and 3 were supported in the simple reaction-time task. There were no significant differences among stressors for either task, although greater differences were reported in the simple than in the choice reaction-time task. A significant difference between the “task-relatedness” of stress levels in the simple task was interpreted as possibly due to a “coping” or “protective adaptive mechanism” in which increases in performance serve to reduce stress. Practical applications were examined.

The present study evaluated the potential for neuroanatomical factors to operate in a simple reaction time task. That is, response latencies were recorded for all ten fingers on a Donders' A reaction time task. Two finger-placement conditions were used, a single response key condition and a multiple response key condition. This latter condition required subjects to place all ten fingers on response keys. 30 male, right-handed subjects participated. No significant effects were found, indicating that there are no intrinsically slow or fast fingers. This finding is discussed in the context of reaction time differences between individual stimulus-response (finger) pairs in choice-reaction time tasks.
