Abstract

In previous research, microsaccades have been suggested as psychophysiological indicators of task load. So far, it is still under debate how different types of task demands are influencing microsaccade rate. This piece of research examines the relation between visual load, mental load and microsaccade rate. Fourteen participants carried out a continuous performance task (n-back), in which visual (letters vs. abstract figures) and mental task load (1-back to 4-back) were manipulated as within-subjects variables. Eye tracking data, performance data as well as subjective workload were recorded. Data analysis revealed an increased level of microsaccade rate for stimuli of high visual demand (i.e. abstract figures), while mental demand (n-back-level) did not modulate microsaccade rate. In conclusion, the present results suggest that microsaccade rate reflects visual load of a task rather than its mental load.

任务难度与微跳率之间的相互作用:视觉负荷关键作用的证据。
在以往的研究中,微跳被认为是任务负荷的心理生理指标。到目前为止,不同类型的任务需求是如何影响微扫视率的还存在争议。本研究探讨了视觉负荷、心理负荷与微跳频之间的关系。14名参与者进行了连续表现任务(n-back),其中视觉(字母vs.抽象图形)和心理任务负荷(1-back到4-back)被操纵为受试者内部变量。记录眼球追踪数据、工作表现数据以及主观工作量。数据分析表明,高视觉需求刺激(如抽象图形)会增加微跳速,而心理需求(n-back水平)对微跳速没有调节作用。综上所述,微跳频反映的是任务的视觉负荷而非心理负荷。
