This investigation utilized a procedure designed to determine patterns of cognitive appraisal, and autonomic reactivity which characterize groups of normals, and paranoid and nonparanoid schizophrenics. Results indicated that both groups of schizophrenics evidenced electrodermal habituation and increased finger pulse constriction. Normals indicated that stress stimuli became less disturbing over trials and displayed both electrodermal and digital vasomotor habituation. Electrodermal habituation curves for paranoids and normals were similar, with nonparanoids evidencing slower habituation. Paranoids tended to under-rate or deny their emotional reactions.
本研究采用了一种程序，旨在确定正常人群、偏执型和非偏执型精神分裂症患者群体所具有的认知评估模式和自主反应模式。结果表明，两组精神分裂症患者均表现出皮肤电反应习惯化和手指脉搏收缩增加。正常人群表明，随着试验次数增加，应激刺激的干扰性降低，并且表现出皮肤电反应和指端血管舒缩习惯化。偏执型患者和正常人群的皮肤电反应习惯化曲线相似，而非偏执型患者的习惯化较慢。偏执型患者往往低估或否认自己的情绪反应。
