This research addressed the relationship between the speed of presentation of stimuli through the auditory and visual modalities and the number of syntagmatic and paradigmatic word-association responses of 49 chronic undifferentiated schizophrenic adults. In word-association tests administered to subjects stimuli were balanced for frequency of occurrence in written English language (frequent, infrequent), word length (long, short), abstraction level (low, medium, high), and part of speech (noun, verb, adjective). The words were presented auditorily at normal speed (equivalent to 10 phonemes per second) and at half speed (equivalent to 5 phonemes per second) speech. Words were also presented visually, using a tachistoscope, at extended fixation speed (equivalent to 1,000 msec.) and at sweep speed (equivalent to 10 msec.). More paradigmatic responses occurred on word stimuli if nouns, long, and frequently occurring presented auditorily; and if concrete, nouns, and presented slowly and visually. Results were compared to previously reported data for aphasic and normal adults, and differentiating features and clinical implications were discussed.
本研究探讨了通过听觉和视觉通道呈现刺激的速度与49名慢性未分化型成年精神分裂症患者的组合性和聚合性单词联想反应数量之间的关系。在对受试者进行的单词联想测试中，刺激在书面英语中的出现频率（高频、低频）、单词长度（长、短）、抽象程度（低、中、高）和词性（名词、动词、形容词）方面是平衡的。单词以正常语速（相当于每秒10个音素）和半速（相当于每秒5个音素）通过听觉呈现。单词也通过速示器以延长注视速度（相当于1000毫秒）和扫描速度（相当于10毫秒）进行视觉呈现。如果名词、长单词且高频出现的单词通过听觉呈现；以及如果具体的、名词且以缓慢速度通过视觉呈现，那么在单词刺激上会出现更多的聚合性反应。将结果与先前报道的失语症患者和正常成年人的数据进行了比较，并讨论了鉴别特征和临床意义。
