A lack of agreement exists among studies of electrodermal habituation in schizophrenia. One explanation for the intractable discrepancies observed concerns the likelihood that there exists intersubject variability in the significance patients attach to stimuli. This possibility is encouraged through the administration of vague and uninformative instructions. A more controlled and sensible procedure, which allows habituation to be measured with greater ecological validity, involves providing subjects with an absorbing alternative task on which to focus their attention after being specifically instructed to ignore the habituation stimulus to the best of their ability.
关于精神分裂症患者皮肤电反应习惯化的研究结果并不一致。对于所观察到的难以解决的差异，一种解释是患者对刺激赋予的重要性可能存在个体间差异。给予模糊且缺乏信息的指示会增加这种可能性。一种更可控且合理的程序，能在更高的生态效度下测量习惯化，该程序是在明确指示受试者尽最大能力忽略习惯化刺激后，为他们提供一项引人入胜的替代任务，让他们将注意力集中在该任务上。
