Eye behaviour provides valuable information revealing one's higher cognitive functions and
state of affect. Although eye tracking is gaining ground in the research community, it is not …

Recent evidence has demonstrated that environmental sampling is a fundamentally
rhythmic process. Both perceptual sensitivity during covert spatial attention and the …

Pupil diameter and microsaccades are captured by an eye tracker and compared for their
suitability as indicators of cognitive load (as beset by task difficulty). Specifically, two metrics …

Classic studies of spatial attention assumed that its neural and behavioral effects were
continuous over time. Recent behavioral studies have instead revealed that spatial attention …

Covert spatial attention is associated with spatial modulation of neural activity as well as with
directional biases in fixational eye movements known as microsaccades. We studied how …

Cognition results from interactions among functionally specialized but widely distributed
brain regions; however, neuroscience has so far largely focused on characterizing the …

Decreases in alpha synchronization are correlated with enhanced attention, whereas alpha
increases are correlated with inattention. However, correlation is not causality, and …

A novel eye-tracked measure of the frequency of pupil diameter oscillation is proposed for
capturing what is thought to be an indicator of cognitive load. The proposed metric, termed …

The pupillary light response is an important automatic physiological response which
optimizes light reaching the retina. Recent work has shown that the pupil also adjusts in …
