对于词汇产生，我们可能会有意识地采用语义或语音搜索策略，但我们是否能够独立地提取词汇信息的不同方面是不确定的。因此，我们研究了语义信息的传播到专门的音素任务的要求下产生的话。42名受试者参加了一项字母口语流利性任务，要求在两分钟内产生尽可能多的S-单词。基于曲线拟合的时间过程中的单词生产，输出爆发（时间集群）被认为是反映快速词汇检索的基础上自动激活扩散，确定。通过各自的分数（0表示无关系，4表示最大关系）评估这些聚类内与聚类之间的语义和音素词相关性。受试者产生27.5（±9.4）个词，属于6.7（±2.4）个聚类。语音和语义词在集群内比集群之间更相关（phon：0.33±0.22 vs. 0.19±0.17，p<0.01; sem：0.65±0.29 vs. 0.37±0.29，p<0.01）。而语音相关的程度与高任务绩效，相反的情况下，语义相关的程度。结果表明，语义信息传播发生，即使有意识地追求单词搜索策略是纯粹的语音。这一点，再加上语义相关性和口头输出之间的负相关关系适合的想法，语义默认模式的词汇搜索，行动对快速任务的性能在给定的情况下，音素口头流畅性。增强的语义和音位词的相关性在相同的时间集群边界内的一致性表明，内容和声音相关的信息之间的相互作用，每当一个新的语义场已经打开。
For word production, we may consciously pursue semantic or phonological search strategies, but it is uncertain whether we can retrieve the different aspects of lexical information independently from each other. We therefore studied the spread of semantic information into words produced under exclusively phonemic task demands. 42 subjects participated in a letter verbal fluency task, demanding the production of as many s-words as possible in two minutes. Based on curve fittings for the time courses of word production, output spurts (temporal clusters) considered to reflect rapid lexical retrieval based on automatic activation spread, were identified. Semantic and phonemic word relatedness within versus between these clusters was assessed by respective scores (0 meaning no relation, 4 maximum relation). Subjects produced 27.5 (±9.4) words belonging to 6.7 (±2.4) clusters. Both phonemically and semantically words were more related within clusters than between clusters (phon: 0.33±0.22 vs. 0.19±0.17, p<.01; sem: 0.65±0.29 vs. 0.37±0.29, p<.01). Whereas the extent of phonemic relatedness correlated with high task performance, the contrary was the case for the extent of semantic relatedness. The results indicate that semantic information spread occurs, even if the consciously pursued word search strategy is purely phonological. This, together with the negative correlation between semantic relatedness and verbal output suits the idea of a semantic default mode of lexical search, acting against rapid task performance in the given scenario of phonemic verbal fluency. The simultaneity of enhanced semantic and phonemic word relatedness within the same temporal cluster boundaries suggests an interaction between content and sound-related information whenever a new semantic field has been opened.
