Abstract

The importance of task requirements in producing visual half-field asymmetries was investigated through manipulation of the criteria by which a central probe and a unilateral target letter were matched. Physical characteristics of the letters were emphasized (those made up of straight lines only vs those having at least one curved feature, e.g. F vs P). An interaction of visual field and type of judgment (match vs mismatch) was found for manual response time. Matching responses were faster to RVF than LVF probes and mismatches were faster to LVF than RVF probes. The significance of this interaction for models of hemispheric asymmetry is discussed.

摘要

通过操纵中央探针与单侧目标字母匹配的标准，研究了任务要求在产生视觉半视野不对称中的重要性。强调了字母的物理特征（仅由直线组成的字母与至少有一个弯曲特征的字母，例如F与P）。发现手动反应时间存在视野与判断类型（匹配与不匹配）的交互作用。对于右侧视野（RVF）探针，匹配反应比左侧视野（LVF）探针更快，而对于不匹配情况，左侧视野探针的反应比右侧视野探针更快。讨论了这种交互作用对半球不对称模型的意义。
