采取图画-词汇干扰实验范式，探索汉语单音节词汇产生中词汇选择和音韵编码之间的交互作用。实验一探测目标图画语义相关项的语音激活，观察到了非目标项的语音激活。实验二探测目标图画语义相关项的字形激活，未发现非目标项的字形激活。在改进实验条件的基础上，实验三验证实验一和二，并探测目标图画字形相关项的语音激活以及语音相关项的字形激活，结果未探测到语义相关项的字形或语音激活、语音相关项的字形激活，只发现了字形相关项的语音激活。实验一至三的结果表明汉语词汇产生中存在目标字字形相关项的语音激活，但不存在从音韵编码阶段至词汇选择阶段的激活反馈。综合上述结果，从是否存在多重的字形或语音激活，以及是否存在从音韵编码至词汇选择的反馈两个方面进行了讨论。研究结果倾向于支持词汇产生中层叠式理论的观点。

英文摘要：

Introduction An important issue in the study of language production concerns the time course of lexical access and possible interactions between lexical selection and phonological encoding. A number of different models have been proposed in the literature to account for how a word is processed for speaking. For example, the discrete two-stage model assumes that the stages of lexical selection and phonological encoding operate in a strict successive order, and no interaction between the stage of lexical selection and phonological encoding. Alternatively, on the basis of spreading activation, the interactive activation model postulates a bi-directional flow of information between different processing levels. Semantic, lexical, and phonological levels are interconnected in a network fashion. Lexical candidates activate their phonological forms before any single candidate has been selected. That is, not only the word forms of the target lemma, but also the semantic competitors become partially activated. The cascading model assumes that there exists interaction between lexical selection and phonological encoding, but no feedback from the stage of phonological encoding to lexical selection. The debates among three models are （ 1 ） whether there is the interaction between lemma selection and phonological encoding; （2） whether all activated semantic items or only a single selected semantic item gives rise to the phonological activation ; （3） whether there is feedback from phonological encoding to lexical selection. Due to confounding of orthography and phonology in alphabetic languages （i. e. , English and Dutch）, the results of the previous studies （Lupker, 1982; Starreveld ＆ La Heij, 1995） need to be interpreted cautiously. Using the independence of orthography and phonology in Chinese, the present experiments investigated （ 1 ） the multiple phonological activations and the multiple orthographic activations of semantically related words of picture name; （2） whether there is the feedbac
