在这项研究中，我们研究了半球间相互作用（IHI）可能促进表现的两种可能机制。 20 名大学生执行了 3 项和 4 项版本的不太复杂的物理身份 (PI) 任务，其中他们确定 2 个字母在感知上是否相同（例如“A”和“A”），以及更复杂的名称身份 (NI) 任务，其中他们确定 2 个字母是否具有相同的名称（例如“A”和“a”）。与之前的工作一致，无论显示中有多少项，IHI 都比简单的 PI 任务更能提高相对复杂的 NI 任务的性能。然而，对于每项任务，IHI 在 4 项显示中对性能的促进作用低于在 3 项显示中的作用。这些结果表明，IHI 通过允许（1）跨半球进行处理划分，以及（2）由接收相对较轻处理负载的半球处理与任务相关的信息来提高性能。 (JINS, 2000, 6, 313–321.)
In this study, we investigated 2 possible mechanisms by which interhemispheric interaction (IHI) might facilitate performance. Twenty university students performed 3- and 4-item versions of a less complex physical identity (PI) task in which they decided whether 2 letters were perceptually identical (e.g., ‘A’ and ‘A’) and a more complex name identity (NI) task in which they decided whether 2 letters had the same name (e.g., ‘A’ and ‘a’). Consistent with prior work, IHI facilitated performance more for the relatively complex NI task than for the simpler PI task regardless of how many items were in the display. However, for each task IHI facilitated performance less in the 4-item displays than in the 3-item displays. These results indicate that IHI facilitates performance by allowing (1) a division of processing across the hemispheres, and (2) task-relevant information to be processed by a hemisphere that receives a relatively light processing load.
