A primary factor affecting a response is the number of possible stimuli, each requiring their response, that is presented. This is an important part of the paradigm. Reaction Time. Simple reaction time refers to reacting to a single stimulus and is usually very fast (around 0.13-0.18s). It is legally recognized that time is divided into years, months, weeks, days, hours, minutes, and seconds. Another type of reaction time, choice reaction time, is the time taken between stimulus and action which requires a choice.

The period of time between the detection of a stimulus at a sensory receptor and the performance of the appropriate response by the effector organ. Typically, there is only one stimulus that repeats throughout the experiment. Reaction time is the interval time between the presentation of a stimulus and the initiation of the muscular response to that stimulus. reaction definition: 1. behaviour, a feeling or an action that is a direct result of something else: 2. someone's…. Definition of Reaction Rate. If this random variation would not be used, the simple choice reaction time task would be very simple, because you could predict when the stimulus would appear. However, unlike the other factors, recovering reaction time affected by these circumstances is quicker and easier. Choice Reaction Time tests general alertness and motor speed. Psychology Definition of ASSOCIATION-REACTION TIME: in any type of word-association test, the time that has elapsed between stimulus presentation and the response. Reaction Time Test. Reaction time has been widely studied, as its practical implications may be of great consequence, e.g. Driver reaction time is the length of time it takes for a person or system to respond to a given stimulus or event.

The speed of a chemical reaction may be defined as the change in concentration of a substance divided by the time interval during which this change is observed: Reaction time is the last dash point for skill-related components of physical fitness. This delay is caused by the time taken for the impulse to travel across the synapses of adjacent neurons. The Reaction Rate for a given chemical reaction is the measure of the change in concentration of the reactants or the change in concentration of the products per unit time. Reaction definition, a reverse movement or tendency; an action in a reverse direction or manner. Many factors have been shown to affect reaction times , including age, gender, physical fitness, fatigue, distraction, alcohol, personality type, and whether the stimulus is auditory or visual. Three basic reaction time paradigms have been described: (1) simple reaction time has a single stimulus and a single predefined response, (2) recognition reaction time has several false … This is due to the fact that there is only one stimulus and one response to it. Reaction time is measured for various reasons in order to identify and manage a slow reaction time. reaction time: [ re-ak´shun ] 1. opposite action or counteraction; the response of a part to stimulation.

Mental chronometry is the study of reaction time (RT; also referred to as "response time") in perceptual-motor tasks to infer the content, duration, and temporal sequencing of mental operations.Mental chronometry is one of the core methodological paradigms of human experimental and cognitive psychology, but is also commonly analyzed in psychophysiology, cognitive neuroscience, and … Reaction time is often used in the context of automobile safety to refer to the amount of time it takes a driver to notice a hazard on the road and react to it by swerving, braking or slowing down. Reaction time is typically slowed after concussion. With slower reaction times, drivers are less able to take action in response to sudden hazards.
