This study examined the use of the P scale of the Eysenck Personality Questionnaire as a pencil and paper estimate of level of affect lability. Groups of subjects differing on the P scale were presented with emotive and non-emotive words. High P (low affect) subjects appeared inhibited in their emotional rating of all words, and displayed a restricted range in their reporting of this rating. Further, the electrodermal activity elicited by these words differed between the groups, with high P subjects again appearing relatively inhibited. These results support the validity of the P scale as a measure of affect lability and have implications for a recent hypothesis of impaired functioning of the reticular activating system in early-onset psychosis. The results may also be interpreted to support the role of significance in elicitation of the orienting response.
本研究考察了使用艾森克人格问卷的P量表作为对情感易变性水平的纸笔评估方法。让在P量表上得分不同的几组受试者面对情感性和非情感性词汇。高P（低情感）受试者在对所有词汇的情感评分中表现出抑制，并且在报告该评分时范围受限。此外，这些词汇引发的皮肤电活动在两组之间存在差异，高P受试者再次表现出相对抑制。这些结果支持了P量表作为情感易变性测量方法的有效性，并对早发性精神病中网状激活系统功能受损的近期假说具有启示意义。这些结果也可以解释为支持意义在引发定向反应中的作用。
