The hypothesis that schizophrenics with flat affect have an interference with imagery mediation of language function was derived from clinical impressions that (1) such patients fail to show appropriate voice emphasis, and (2) that word imagery contributes to normal vocal emphasis patterns. Experiment 1 acoustically measured the emphasis patterns in schizophrenics with and without flat affect as they read text controlled for word imagery. Experiment 2 studied the effect of imagery in a paired-associate learning task in the same patients. The results supported the hypothesis, both for emphasis patterns and learning rates. These findings suggest that flat affect may be the product of factors in the schizophrenic process interacting with cognitive processes that are independent of the disease.
情感平淡的精神分裂症患者在语言功能的意象中介方面存在干扰这一假设，源自以下临床印象：（1）此类患者未能表现出适当的语音强调；（2）词汇意象有助于形成正常的语音强调模式。实验1通过声学方法测量了情感平淡和非情感平淡的精神分裂症患者在阅读受词汇意象控制的文本时的强调模式。实验2研究了意象在同一批患者的配对联想学习任务中的作用。结果在强调模式和学习率方面均支持了该假设。这些发现表明，情感平淡可能是精神分裂症过程中的因素与独立于该疾病的认知过程相互作用的产物。
