Eye movements during visuospatial judgements

By Katie L. Meadmore, Itiel E. Dror, Romola S. Bucks and Simon P. Liversedge

Abstract

The goal of the current research was to determine whether eye movements reflect different underlying cognitive processes associated with visuospatial relation judgements. Ten participants made three different judgements regarding the position of a dot in relation to a bar; an above/below judgement, a near/far judgement, and a precise distance estimation. The results highlight similarities between above/below and near/far visuospatial judgements; specifically, such binary judgements were fast, reflexive and did not require precise distance computation. In contrast, estimating distance was comparatively cognitively demanding and required precise distance computation, as evidenced through distinct scan paths. The eye movement data provide significant insight into the cognitive processes underlying visuospatial judgements, showing aspects of visuospatial processing that are similar, as well as those that differ between task
