This study examined changes in pupil size during response preparation in a finger-cuing task. Based on the Grouping Model of finger preparation [Adam, J.J., Hommel, B. and Umiltà, C., 2003b. Preparing for perception and action (I): the role of grouping in the response-cuing paradigm. Cognitive Psychology. 46, (3), 302-358.; Adam, J.J., Hommel, B. and Umiltà, C., 2005. Preparing for perception and action (II) Automatic and effortfull Processes in Response cuing. Visual Cognition. 12, (8), 1444-1473.], it was hypothesized that the selection and preparation of more difficult response sets would be accompanied by larger pupillary dilations. The results supported this prediction, thereby extending the validity of pupil size as a measure of cognitive load to the domain of response preparation.
本研究考察了在手指提示任务的反应准备过程中瞳孔大小的变化。基于手指准备的分组模型[亚当，J.J.，霍梅尔，B.和乌米塔，C.，2003b。为感知和行动做准备（I）：分组在反应提示范式中的作用。认知心理学。46，（3），302 - 358；亚当，J.J.，霍梅尔，B.和乌米塔，C.，2005。为感知和行动做准备（II）反应提示中的自动和费力过程。视觉认知。12，（8），1444 - 1473。]，研究假设更困难反应集的选择和准备会伴随着更大的瞳孔扩张。结果支持了这一预测，从而将瞳孔大小作为认知负荷度量的有效性扩展到反应准备领域。
