A free, easy-to-use, computer-based simple and four-choice reaction time
programme: The deary-liewald reaction time
A small decrease in the intensity of light, compared with daylight, extends the sensory-motor reaction time
by 0.6-0.7 s, and when the lighting is less than 2 lux, the reaction time
is increased to 2-3 s.
A demonstration of the reaction times
, percentage yields and melting points of all the compounds synthesized by conventional and microwave-assisted methodology is given in Table-2.
The interpretation of reaction time
in information-processing research.
The purpose of simple RT test is to determine the minimum reaction time
, when the stimulus is unique, simple, and unambiguous, and the response is formed from a simple, ordinary, and automatic movement.
A statistical significance increase in reaction time
could also be seen in mean RT in both vibration conditions in all eighteen volunteers.
is defined as the interval of time between the application of a stimulus and initiation of a muscle response.1 Various researches in the past have shown that it is a valid parameter which indicates the ability of the nervous system to receive sensory information and synchronize movement in response to this sensory information which is then executed through the peripheral nervous system.2 In addition to the type of stimulus and the intensity of stimulus, other factors such as age, gender, fatigue, arousal and alcohol consumption are known to affect the reaction time
Auditory reaction time
is associated with efficient spiral organ receptors in the middle ear, which transfer sound to the temporal lobes of cerebral cortex via sensory neurons.
Evenbackin 1936, Greenshields  conducted a study on the determination of the probability distribution of reaction time
. Reaction times
are normally approximated with lognormal probability distribution with the parameters [mu] and [[sigma].sup.2] [17, 18].
Before the experiment, the driver was familiarized with the devices used for the experiment to avoid the abnormal physiological data and the reaction time
Subjects were assessed before and after intervention for changes in audiovisual reaction times
(using Brain Fit Model No.
; is a person's hereditary specifity which is the time between stimulant and his/her first muscle reaction or his/her first movement .
