摘要:

许多证据表明权力在大脑中是以垂直空间来进行表征的, 具体而言为言语和视觉空间编码。前人研究发现两种编码具有情境依赖性, 即当前任务决定了激活哪种编码。一般的词类判断任务主要依赖于言语编码。然而仍不确定的是, 当排除言语空间编码后, 词类判断任务能否激活视觉空间编码。本研究拟借助双任务范式探讨此问题。实验结果发现单任务条件下出现权力-空间交互, 并且双任务条件下, 这一交互只受到视觉空间次要任务的干扰。这说明, 词类判断任务也可依赖视觉空间编码, 并进一步支持了权力空间表征的情境依赖性。

Abstract:

There is much evidence suggesting that power is represented as vertical space in our brain, specifically, verbal-spatial coding (amodal representation) and visuospatial coding (modal representation). Both codes are context-dependent, and the activation of which depends on the concurrent task. Studies using the dual-task paradigm have revealed that the explicit power judgment task activates both codes, whereas the semantic category judgment task mainly activates the verbal-spatial codes. However, it is still unclear whether the semantic category judgment task can activate the visuospatial codes when excluding the verbal-spatial codes. Thus, the aim of the present study is to explore whether the semantic category judgment task can activate the visuospatial codes when excluding verbal-spatial information.

Using the dual-task paradigm, the present study tested the effect of visuospatial and verbal secondary task on the power-space interactions after excluding the verbal-spatial codes. In the experiment, a power word was presented in the center of the screen with two response labels (“human” and “animal”) at the up or down side of the target word. The response labels were mapping to the up and down cursor keys in the keyboard. The locations of the two labels exchanged from trial to trial. This manipulation could exclude the activation of the verbal-spatial codes. Participants were required to judge the semantic category of the word in three task conditions: the single task, the visual dual task, and the verbal dual task. It is hypothesized that the power-space interactions would be affected by the visual secondary task, but not by the verbal secondary task.

Consistent with our prediction, the results showed that the power-space interactions during the semantic category judgment task were affected by the visual secondary task, but not by the verbal secondary task.

The findings suggested that (1) the semantic category judgment task could activate visuospatial codes (modal representations) individually after excluding the verbal spatial-codes and (2) the visuospatial codes were only interfered by the visuospatial secondary task.

Key words: power-space representations, context-dependent, visuospatial coding, verbal-spatial coding
