报告了三个使用轮廓面部和昆虫刺激的实验。受试者要么关注各个特征元素之间的空间关系，或者独立于各个特征元素（整体处理条件），要么关注（使用相同的刺激）某些离散特征元素的形状（分析条件）。他们定时对横向呈现的目标和非目标进行歧视性的手动反应。一般在对人脸和虫子进行整体处理的情况下出现左视野优势，而在需要分析处理时则出现右视野优势；在一对连续任务中的第二个任务中，当两个任务中较困难的任务首先出现时，对于这两个任务中较困难的任务，并且使用目标刺激而不是非目标刺激，效果更为明显。受试者要注意的刺激的那些方面可以确定横向不对称性，以及实际刺激本身。支持分析/整体处理区别，而不是基于语言/视觉空间处理的区别。任务难度和顺序是未来研究中需要控制和研究的重要变量。
Three experiments employing outline face and bug stimuli were reported. Subjects either attended to the spatial relationships between and otherwise independent of the individual feature elements (holistic processing condition) or instead attended (with the same stimuli) to the shape of certain discrete feature elements (analytic condition). They were timed in performing discriminatory manual responses to laterally presented targets and nontargets. A left visual field superiority generally occurred under conditions of holistic processing both for faces and bugs and a right field superiority when analytic processing was required; effects were more apparent in the 2nd of a pair of sequential tasks, when the more difficult of the 2 tasks came first, for the more difficult of the 2 tasks, and with target rather than, nontarget stimuli. Those aspects of a stimulus to which a subject is set to attend can determine lateral asymmetries, as well as the actual stimuli themselves. An analytic/holistic processing distinction is supported, rather than one based on verbal/visuospatial processing. Task difficulty and order are important variables to be controlled and studied in this context in future research.
