Simple Reaction Time (SRT) is the elapsed interval between the presentation of a single, known stimulus and the initiation of a pre-specified response. In other words, you know in advance exactly how to react, so the only “decision” is when to move.

Choice Reaction Time (CRT) is the interval between the onset of one of several possible stimuli and the initiation of the correct, pre-specified response.

Eye–hand coordination is the seamless integration of visual perception and manual movement, where your eyes detect a target’s position and motion and your brain instantly translates that information into precise, timely hand actions.

Multiple Object Tracking is the capacity‐limited ability to simultaneously follow and update the spatial positions of several moving targets among identical distractors, relying on distributed attention and visuospatial working memory to maintain each object’s identity in a dynamic scene.

A Stroop task requires you to name a stimulus’s relevant feature—its ink color or its numerical value—while ignoring an automatic but conflicting feature (word meaning or digit size), measuring interference, selective attention, and inhibitory control.

Flanker compatibility describes how adjacent flankers affect response times and accuracy to a central target—congruent flankers facilitate faster, more accurate responses, while incongruent flankers slow responses and increase errors—indexing selective attention and interference control.
