关于词对音位知觉的影响的性质

ON THE NATURE OF LEXICAL EFFECTS ON PHONEME PERCEPTION

本文报告的实验以反应时作指标研究词对音位知觉的影响的性质,检验Ganong提出的两种模型——相互作用模型和范畴模型。实验结果表明,词的作用随反应时的增加而减小。结果倾向于支持相互作用模型。

Using the reaction time (RT) determined by Fox (1984) as a paradigm,this experiment investigated the nature of lexical effects on phoneme per-ception, and examined two models suggested by Ganong (1980) for explai-ning lexical effects. The results showed that lexical effects did notchange across the two RT ranges after the lexical access, and that the resp-onse distribution across RT ranges and stimuli predicted an increase oflexical effects in the larger RT ranges. Thus lexical effects were reducedas the reaction time was increased. The paper discussed the implicationsof this conclusion on the two models suggested by Ganong and on thetheories of speech perception.
