Behaviours of 40 healthy, 30 neurotic and 35 schizophrenic subjects were compared in the situation of formation of motivation for successful performance of a complicated task. In the case of an easy task, the subjects had to push a button maximally quickly after the second buzz in a double sound stimulus; in the case of the complicated task, after special motivating instruction, the subjects had to show motor response coinciding with the second buzz. The easy task was performed by all participants of the experiment, while the complicated one was performed by healthy subjects and by neurotics after the course of therapy. The differences in the performance were accompanied by specific peculiarities in brain slow potentials. The successful performance induced an increase in the strength of conditional negative and post-imperative negative waves in frontal lobes in the healthy and treated neurotics. Pathological functioning of schizophrenics reflected in quantitative and qualitative modifications of the electrical response patterns.
在形成完成复杂任务动机的情境中，对40名健康受试者、30名神经症患者和35名精神分裂症患者的行为进行了比较。对于简单任务，受试者在双声刺激的第二次嗡嗡声后要尽可能快地按下按钮；对于复杂任务，在经过特殊的激励指导后，受试者必须做出与第二次嗡嗡声一致的运动反应。实验的所有参与者都完成了简单任务，而健康受试者和经过治疗的神经症患者完成了复杂任务。表现上的差异伴随着脑慢电位的特定特征。成功完成任务会使健康受试者和经过治疗的神经症患者额叶的条件负波和命令后负波强度增加。精神分裂症患者的病理功能反映在电反应模式的数量和质量变化上。
