Eye Blink Rate

Eye blink rate is the number of eyelid closures measured over a defined period, providing a simple behavioral indicator of ocular protection and cognitive state. Blinking spreads the tear film across the cornea, removes particles, and briefly interrupts visual input; spontaneous blink timing is shaped by brainstem motor circuits and varies with attention, cognitive demand, emotional state, and environmental conditions. In behavioral research, measuring blink rate can help assess visual attention, task engagement, fatigue, and responses to changing mental demands. Because it is noninvasive and relatively easy to record, eye blink rate complements other measures of behavior and human performance.

The Attentional Blink

0 Views •

2023

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In order for recognition of a certain stimulus to take place, visual attention needs to be directed towards said stimulus. To the earliest parts of the visual system, objects are not objects, they are collections of visual features-lines, corners, changes in texture, color, and light. Attention is the resource that is necessary for later processing in order to recognize what a given bundle of features adds up to. This makes...

Eye movement monitoring (or eye tracking) reveals where in space the eyes linger, when and for how long. Here, we demonstrate how eye tracking can be used to investigate the integrity of memory in multiple participant populations, without requiring verbal, or otherwise explicit, reports.

A Dual Task Procedure Combined with Rapid Serial Visual Presentation to Test Attentional Blink for Nontargets

2025

Eye tracking is a non-invasive method to probe information processing. This article describes how eye tracking can be used to study gaze behavior during a flight simulation emergency task in low-time pilots (i.e., <350 flight hours).
