High working memory performers have efficient eye movement control systems under Reading Span Test

Abstract

Controlled eye movements are critical in performing highly goal oriented behavior such as text reading. Previous studies have examined the relationship between working memory capacity and eye movement control during working memory task. However, the results were inconsistent, due to a methodological issue including the predictability of target location. In the present study, we used Japanese version of reading span test, where the position of to-be-remembered word is not predictable so that more efficient attentional control is required, and investigated how working memory capacity contributes to eye movement control during reading span test. Results based on total fixation time revealed that highworking memory performers efficiently control or shift their attention under high memory load.
