This study investigated the acquisition of affective and neutral words in a paired-associate list by chronic schizophrenics and normals. Ten paired associates in which stimulus terms were nonsense syllables and response terms were words (five affective and five neutral) were learned by 30 chronic schizophrenics (15 male, 15 female) and 30 normals (15 male, 15 female) according to an anticipation procedure. The schizophrenics learned significantly fewer affective words than neutral words, while normals learned an equal number of affective and neutral words. This effect, however, progressively diminished throughout trials for the schizophrenics such that no differences were observed in the final trial for the two types of response words. These results are discussed in terms of habituation of an anxiety response evoked by the affective words.
本研究调查了慢性精神分裂症患者和正常人在配对联想列表中对情感词和中性词的习得情况。30名慢性精神分裂症患者（15名男性，15名女性）和30名正常人（15名男性，15名女性）按照预期程序学习了10对配对联想词，其中刺激词是无意义音节，反应词是单词（5个情感词和5个中性词）。精神分裂症患者学习的情感词明显少于中性词，而正常人学习的情感词和中性词数量相等。然而，对于精神分裂症患者来说，这种效应在整个试验过程中逐渐减弱，以至于在最后一次试验中，两种类型的反应词没有观察到差异。这些结果根据情感词引发的焦虑反应的习惯化进行了讨论。
