Abstract

Three experiments have tested for the existence of laterality effects in iconic storage by employing a Sperling partial-report paradigm and lateralized presentations of alphabetical or pattern material. Even though an overall laterality effect was found in favor of the right visual field for the alphabetical material and in favor of the left visual field for the pattern material, the amount and time decay of partial-report advantage was similar in the two visual fields. These results indicate that hemispheric asymmetries occur beyond the iconic stage of visual information processing.

摘要

三项实验通过采用斯珀林部分报告范式以及按字母顺序排列或图案材料的偏侧呈现，测试了图像存储中是否存在偏侧效应。尽管发现了总体偏侧效应，即对于字母材料而言，右侧视野占优势；对于图案材料而言，左侧视野占优势，但部分报告优势的量和时间衰减在两个视野中是相似的。这些结果表明，半球不对称性出现在视觉信息处理的图像阶段之后。
