Cognitive load modulation of distractor processing using pupillary responses

Investigating cognitive load modulation of distractor processing using pupillary luminance responses in the anti‐saccade paradigm

We examined the cognitive load theory of attention in the interleaved pro- and anti-saccade task, and used luminant distractors to evoke automatic pupillary responses to evaluate distractor processing. Greater pupillary dilation following dark distractors was observed in the anti-saccade than the pro-saccade preparation. These results support the load theory of attention, highlighting the potential of using involuntary changes in pupil size to objectively investigate attentional selection under load.
