A psychomotor vigilance task (PVT) is a sustained-attention, reaction-timed task that measures the consistency with which subjects respond to a visual stimulus.Research indicates increased sleep debt or sleep deficit correlates with deteriorated alertness, slower problem solving, declined psychomotor skills, and increased rate of false responses.
The range of sensory discrimination of a given sense also varies considerably both within and across sensory modality. For example, Kiesow (1903) found in a reaction time task of taste that human subjects are more sensitive to the presence of salt on the tongue than of sugar, reflected in a faster RT by more than 100 ms to salt than to sugar.

Professor Joan Vickers is credited as the originator of quiet eye theory, [1] [4] and has been working on the topic since the early 1980s. [5] Vickers examined the gaze patterns of national-level basketball players during free throw shots, finding that expert players maintained a longer final fixation before beginning their movements compared to non-expert players.
[14] [15] In 2014, a meta-analysis of twenty studies showed that n-back training has small but significant effect on Gf and improve it on average for an equivalent of 3–4 points of IQ. [16] In January 2015, this meta-analysis was the subject of a critical review due to small-study effects.
The data showed large reaction time differences between cue repetitions and task repetitions (same task, different cue), and negligible differences between task repetitions and task alternations, consistent with the compound-stimulus model. Thus, the switch costs observed in the explicit task-cuing procedure may not reflect executive processes ...
Eye–hand coordination (also known as hand–eye coordination) is the coordinated motor control of eye movement with hand movement and the processing of visual input to guide reaching and grasping along with the use of proprioception of the hands to guide the eyes, a modality of multisensory integration.
The reaction times of the best fast draw shooters is 0.145 seconds, which means that the gun is cocked, drawn, aimed (from the hip), and fired in just over 0.06 seconds. To establish a World Fast Draw Association record, a second shot must be fired in the same competition that is no more than 0.30 seconds slower than the first; this is intended ...
This results in decreased reaction times in Posner's spatial cueing task for validly cued targets, [3] and slower reaction times in response to invalidly cued targets: "Detection latencies are reduced when subjects receive a cue that indicates where in the visual field the signal will occur" (Posner, Snyder & Davidson, 1980).
