This study examined whether differential word length effects in the two visual fields imply hemisphere-dependent modes of word recognition. Length was defined as the number of constituent characters of Chinese foreign names (Experiments 1 and 2), as the number of constituent morphemes of three-character words (Experiments 3 and 4), and as that of constituent words of phrases (Experiments 5 and 6). Two types of experimental tasks were adopted, one required linguistic judgments on overall items (Experiments 1, 3, and 5) and the other was target detection tasks performed on the same set of stimuli (Experiments 2, 4, and 6). Five of the six experiments failed to find any kind of interaction between length and visual field. An interaction was observed only for the detection of characters embedded in foreign names, that is, when lexical access is least involved in the task, suggesting that word recognition plays a minimum role in the phenomenon. Other observations suggested that modes of word recognition are more frequency-dependent than hemisphere-dependent, and that Chinese compound words and phrases, although hardly distinguishable, do behave differently.
本研究考察了两个视野中不同的词长效应是否意味着单词识别存在半球依赖模式。词长在实验1和2中定义为中外人名的组成字符数,在实验3和4中定义为三字词的组成语素数,在实验5和6中定义为短语的组成单词数。采用了两种类型的实验任务,一种是对整体项目进行语言判断(实验1、3和5),另一种是对同一组刺激执行目标检测任务(实验2、4和6)。六个实验中有五个未能发现词长和视野之间存在任何形式的交互作用。仅在检测嵌入外国人名中的字符时观察到交互作用,也就是说,当任务中词汇通达最少参与时,这表明单词识别在该现象中起的作用最小。其他观察结果表明,单词识别模式更多地依赖于频率而非半球,并且中文复合词和短语虽然难以区分,但表现确实不同。
