This study investigates the role of morphology during speech planning in Mandarin Chinese. In a long-lag priming experiment, thirty-two Mandarin Chinese native speakers were asked to name target pictures (e.g., "" /shan1/ "mountain"). The design involved pictures referring to morpheme-related compound words (e.g., "" /shan1yang2/ "goat") sharing a morpheme with the first (e.g., "" /shan1/ "mountain") or the second position of the targets (e.g., /nao3/ "brain" with prime /dian4nao3/ "computer"), as well as unrelated control items. Behavioral and electrophysiological data were collected. Interestingly, the behavioral results went against earlier findings in Indo-European languages, showing that the target picture naming was not facilitated by morphologically related primes. This suggests no morphological priming for individual constituents in producing Mandarin Chinese disyllabic compound words. However, targets in the morpheme-related word condition did elicit a reduced N400 compared with targets in the morpheme-unrelated condition for the first position overlap in the ERP analyses but not for the second, suggesting automatic activation of the first individual constituent in noun compound production. Implications of these findings are discussed.
本研究调查了汉语普通话言语计划过程中词法的作用。在一项长时滞后启动实验中，32名以汉语普通话为母语的人被要求说出目标图片（例如，“/shan1/”“山”）的名称。实验设计包括与词素相关的复合词（例如，“/shan1yang2/”“山羊”）的图片，这些复合词与目标词的第一个（例如，“/shan1/”“山”）或第二个位置（例如，目标词“/nao3/”“脑”，启动词“/dian4nao3/”“电脑”）共享一个词素，以及不相关的控制项目。收集了行为和电生理数据。有趣的是，行为结果与印欧语系语言的早期研究结果相反，表明形态相关的启动词并未促进目标图片的命名。这表明在生成汉语双音节复合词时，单个成分不存在词法启动效应。然而，在ERP分析中，对于第一个位置重叠的情况，词素相关词条件下的目标词与词素无关条件下的目标词相比，确实引发了N400波幅的降低，但第二个位置的情况并非如此，这表明在名词复合词生成过程中，第一个单个成分会自动激活。讨论了这些发现的意义。
