Absolute and relative sizes of global and local visual stimuli have been suggested as the prime determinants of the so-called global precedence effect; however, in none of these studies has the relative size of the two levels been manipulated. Difference in size seems to be the most distinct aspect of differentiating global and local levels of a visual stimulus. In this study the effect of variations in relative size of global and local levels on the global-local advantage and interference effects was examined. Analysis showed that, when the stimulus was displayed at a peripheral location, relative size was probably the prime determinant of global advantage and interference. In addition, both global and local information was processed faster when the stimulus was projected to the left visual field than to the right one. This finding was more compatible with the hypothesis of verbal-visuospatial hemispheric specialisation than with a part-whole dichotomy.
全局和局部视觉刺激的绝对大小和相对大小被认为是所谓全局优先效应的主要决定因素；然而，在这些研究中，没有一项对两个水平的相对大小进行过操纵。大小差异似乎是区分视觉刺激的全局和局部水平最明显的方面。在本研究中，考察了全局和局部水平相对大小的变化对全局-局部优势和干扰效应的影响。分析表明，当刺激呈现于外周位置时，相对大小可能是全局优势和干扰的主要决定因素。此外，当刺激投射到左视野时，全局和局部信息的处理速度都比投射到右视野时更快。这一发现与言语-视觉空间半球特化假说更相符，而非与整体-部分二分法相符。
