Pupil‐size changes are typically associated with the pupil light response (PLR), where they
are driven by the physical entry of light into the eye. However, pupil‐size changes are also …

Here we show that the pupillary light response reflects exogenous (involuntary) shifts of
attention and inhibition of return. Participants fixated in the center of a display that was …

Pupil size is modulated by various cognitive factors such as attention, working memory,
mental imagery, and subjective perception. Previous studies examining cognitive effects on …

In brightness, the pupil constricts, while in darkness, the pupil dilates; this is known as the
pupillary light response (PLR). The PLR is driven by all photoreceptors: rods and cones …

Peripheral drift is a specific type of illusory motion that causes observers to perceive motion
in a static image. We aimed to determine whether pupil dilation occurs during the perception …

Recent findings in experimental psychology suggest that pupillometry, the measurement of
pupil size, can provide insight into cognitive processes associated with effort and target …

In multiple item visual search, it is controversial whether one or more attentional templates
can be maintained simultaneously. Recent evidence suggests that we switch between …
