The human task-evoked pupillary response provides a sensitive physiological index of the
intensity and online resource demands of numerous cognitive processes (eg, memory …

Cognitive pupillometry is the measurement of pupil size to investigate cognitive processes
such as attention, mental effort, working memory, and many others. Currently, there is no …

The eye pupil is an organ optimally designed by evolution to control the amount of light
entering the eye so as to obtain sharp visual images and allow monitoring of as much as …

The pupil of the eye provides a rich source of information for cognitive scientists, as it can
index a variety of bodily states (eg, arousal, fatigue) and cognitive processes (eg, attention …

In 3 experiments, we examined fluctuations in working memory (WM) performance and
associated changes in pretrial and task-evoked pupil diameter. Additionally, we examined …

Pupillometry has become a standard measure for assessing arousal state. However,
environmental factors such as luminance, a primary dictator of pupillary responses, often …

The measurement of pupil diameter in psychology (in short,“pupillometry”) has just
celebrated 50 years. The method established itself after the appearance of three seminal …

Pupillometry has been one of the most widely used response systems in psychophysiology.
Changes in pupil size can reflect diverse cognitive and emotional states, ranging from …

The course of pupillary constriction and dilation provides an easy-to-access, inexpensive,
and noninvasive readout of brain activity. We propose a new taxonomy of factors affecting …

Pupillometry is the study of changes in the diameter of the pupil as a function of cognitive
processing. This review paper provides a brief historical overview of the study of …
