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 (

CHOICE REACTION TIME IN WORKERS USING TRICHLOROETHYLENE
Medical Journal of Australia, 1978Eight-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.

Simple and Choice Reaction Times in Schizophrenia
Archives of Neurology And Psychiatry, 1959In a recent study of simple and choice reaction times in patients with cerebral disease, it was found that simple reaction time differentiated brain-damaged and control patients quite as well as did choice reaction time. 1 Indeed, in a number of comparisons, simple reaction time appeared to be a somewhat more effective discriminator than choice ...

Choice Reaction Times in Depressive States
British Journal of Social and Clinical Psychology, 1976An experiment was performed in which two components of response latency, decision time (DT) and movement time (MT), were measured in two relatively homogeneous samples of neurotic and psychotic depressive patients, together with a normal control group. It was found that whereas both DT and MT were significantly longer in the depressive samples than in ...

Models for Choice-Reaction Time
Psychometrika, 1960In the two-choice situation, the Wald sequential probability ratio decision procedure is applied to relate the mean and variance of the decision times, for each alternative separately, to the error rates and the ratio of the frequencies of presentation of the alternatives.

Sex difference in choice reaction time
British Journal of Psychology, 1980The 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.

Age, Cardiac Output and Choice Reaction Time
Nature, 1966IN 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 ...

RELATIVE FREQUENCY EFFECT ON CHOICE REACTION TIME
Perceptual and Motor Skills, 1980Subjects 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.

Square-Root Formula for Choice Reaction Time
Perceptual and Motor Skills, 1996The power law of choice reaction time, first proposed by Kvålseth (1980), is further discussed. It is shown that the so-called Hick-Hyman law is a special case of the power law. It is suggested that a particular square-root case provides a most concise and adequate formula lor predicting reaction time when the number of equiprobable stimulus-response ...

Multiple Choice Reaction Time and Movement Time during Physical Exertion
Research Quarterly. American Association for Health, Physical Education and Recreation, 1971Abstract Subject performed a five-choice reaction time (RT) and movement time (MT) task while walking on a treadmill at heart rates (HR) of approximately 80 (standing still), 115, 145 and 175 beats per minute (bpm). Five-choice RT was optimal at a HR of 115 bpm and worst at 175 bpm, thereby supporting the hypothesis of an inverted U relationship ...
