Choice reaction time

Anaesthesia, 1983
Summary Postoperative psychomotor performance changes were measured in three groups of thirteen subjects using a portable serial four‐choice reaction time apparatus. Anaesthesia consisted of either thiopentone, nitrous oxide and halothane (thiopentone subjects) or methohexitone and fentanyljnitrous oxide and incremental methohexitone (

Effects of smoking on simple and choice reaction time

Psychopharmacology, 1994
Twenty-nine subjects performed a reaction time task with four levels of choice-task complexity under non-smoking, sham smoking, and low, medium and high nicotine cigarette conditions. Nicotine reduced decision time, while sham smoking increased decision time. This effect was independent of subjects' habitual levels of cigarette consumption.

The Effects of Hypoxia on Choice Reaction Time and Movement Time

Ergonomics, 1970
An investigation was made of the effects on choice reaction time and movement time of hypoxia (oxygen deprivation) induced by a reduction in total air pressure inside a decompression chamber. The subjects were adult humans who were given no pre training on the task used, were tested once at a pressure level equivalent to some altitude between ground ...

CHOICE REACTION TIME IN WORKERS USING TRICHLOROETHYLENE

Medical Journal of Australia, 1978
Eight-choice reaction time studies were carried out on women using trichloroethylene (TCE) as an industrial solvent, and simultaneous tests were performed on control subjects. The women exposed to TCE showed an increase in choice reaction time compared with the control subjects.

RELATIVE FREQUENCY EFFECT ON CHOICE REACTION TIME

Perceptual and Motor Skills, 1980
Subjects gave either vocal (position-naming) or manual (button-press) responses to spatially arrayed lights in a four-alternative choice reaction task. Relative stimulus frequency, stimulus discriminability, and S-R compatibility were each shown to be significant determinants of RT.

Binocular interactions measured by choice reaction times in pigeons

Behavioural Brain Research, 1987
In 7 pigeons binocular interactions were studied by recording monocular and binocular choice reaction times (RTs) to a pattern discrimination task. In all the animals binocular responses were found to be significantly faster than monocular RTs. In order to assess whether binocular advantage might be ascribed to a neural interaction between the two eyes,

Choice Reaction-Time as a Function of Meaningful Similarity

The American Journal of Psychology, 1963
The time required to make a choice between alternative stimuli has been shown to be directly related to the degree of physical similarity between the stimuli. Several studies exemplifying this relationship have used displays varying along such physical continua as wave-length, frequency, and linear extent.' All these types of stimuli allow for an ...

Age, Cardiac Output and Choice Reaction Time

Nature, 1966
IN an earlier communication to Nature1 it was argued that the attempt to resolve the discrepancy in data on choice reaction time in relation to age in terms of the effective duration of signals2 must be regarded as inadequate. The observations were based on a small sample (N = 48) of data from a psycho-physiological study of the possible effects of ...

Choice Reaction Time as a Function of Frequency Differences

Perceptual and Motor Skills, 1973
Sixteen Ss made same-different choice reactions (CRT) to 10 pairs of pure tones differing from 10 to 100 Hz (different) and 6 pairs of zero frequency difference (same). Results indicated that, based on the number of errors, the stimuli represented three different perceptual levels.

Sex difference in choice reaction time

British Journal of Psychology, 1980
The decision and movement time components of a visual choice reaction‐time task were examined using students and visitors to a university exhibition. The results of two separate studies showed that women have a faster decision time than men, and that men have a faster movement time.
