通过要求患有单侧半球疾病的患者对一种、两种、三种或四种刺激之一做出不同的反应，延长了反应时间实验。评估基于无脑疾病的对照患者的表现。研究发现，所有组的反应时间都是任务复杂性的递增函数。虽然两组脑损伤患者的速度都比对照组患者慢，但在所有条件下，单侧右半球疾病患者的表现与对照组相似。然而，随着任务变得更加复杂，患有左半球疾病的患者的反应速度表现出更明显的迟缓。结果表明，与右半球疾病患者相比，在复杂性增加的情况下，左半球疾病患者的决策速度受到相对更大的损害。
The reaction time experiment was extended by requiring patients with unilateral hemispheric disease to respond differentially to one of one, two, three, or four stimuli. Evaluation was based on the performance of control patients without cerebral disease. Reaction time was found to be an increasing function of the complexity of the task in all groups. While both groups of brain-damaged patients were slower than control patients, under all conditions, the performance of those with unilateral right hemisphere disease paralleled that of controls. The patients with left hemisphere disease, however, showed a more marked retardation in speed of response as the task grew more complex. The results suggest patients with disease of the left hemisphere show relatively greater impairment in speed of decision making in situations of increased complexity than do patients with right hemisphere disease.
