[15] [16] Similarly, increasing the duration of a stimulus available in a reaction time task was found to produce slightly faster reaction times to visual [15] and auditory stimuli, [17] though these effects tend to be small and are largely consequent of the sensitivity to sensory receptors. [8]
Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action. S–R compatibility has been described as the "naturalness" of the association between a stimulus and its response, such as a left-oriented stimulus requiring a response from the left side of the body.
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.
In the IVA-2 CPT, clients are told that they will see or hear the numbers "1" or "2" and that they are to click the mouse when presented with a visual or auditory "1" and inhibit clicking when presented with a "2". The task is made more challenging by the shifting of modalities between the visual and auditory stimuli.
The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.
Response Time Variability: A time measurement of how consistently the microswitch is pressed. Response Time: A time measurement of how fast or slow information is processed and responded to. d' Signal Detection: A time measurement of how fast performance drops. Commission Errors: A measure of impulsivity: how many times the non-target is pressed.
Visual reinforcement audiometry (VRA) is a key behavioural test for evaluating hearing in young children. [ 1 ] [ 2 ] First introduced by Liden and Kankkunen in 1969, VRA is a good indicator of how responsive a child is to sound and speech and whether the child is developing awareness to sound as expected.
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).
