In three experiments, we examined the internal processing mechanisms of relatively independent visual-form subsystems. Participants first viewed centrally presented word pairs and then completed word stems presented beneath context words in the left or right visual field. Letter-case-specific priming in stem completion was found only when the context word was the same word that had previously appeared above the primed completion word and the items were presented directly to the right cerebral hemisphere. This pattern of results was not found when participants deliberately recollected previously presented words when completing the stems. Results suggest that holistic processing, not parts-based processing as assumed in many contemporary theories of visual-form recognition, is performed in a subsystem that distinguishes specific instances in the same abstract category of form and that operates more effectively in the right hemisphere than in the left hemisphere.
在三项实验中，我们研究了相对独立的视觉形式子系统的内部加工机制。参与者首先观看中央呈现的单词对，然后完成出现在左或右视野中上下文单词下方的词干。只有当上下文单词与之前出现在被启动完成单词上方的单词相同时，并且项目直接呈现给右半球时，才会在词干完成任务中发现特定字母大小写的启动效应。当参与者在完成词干时刻意回忆之前呈现的单词时，未发现这种结果模式。结果表明，整体加工而非许多当代视觉形式识别理论所假设的基于部分的加工，是在一个子系统中进行的，该子系统区分同一抽象形式类别中的特定实例，并且在右半球比在左半球更有效地运作。
