Gender differences in choice reaction time: evidence for differential strategies

Ergonomics, 1999
This study considered the hypothesis that on some tasks men and women might employ different information processing strategies. Twelve male and 12 female participants performed a 2- and 4-choice, compatible and incompatible, choice reaction time task that required a verbal response to a spatial location target stimulus.

Square-Root Formula for Choice Reaction Time

Perceptual and Motor Skills, 1996
The 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 ...

Simple and Choice Reaction Times in Schizophrenia

Archives of Neurology And Psychiatry, 1959
In 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 ...

Alcohol and the cognitive aspects of choice reaction time

Psychopharmacology, 1982
In a repeated-measures experiment 18 men and 8 women were given ethanol which raised their mean blood alcohol concentration (BAC) to 0, 21, 50 and 73 mg/100 ml. Using the ERM apparatus (Schuhfried Instruments, Austria), which measures choice reaction time to a task with high cognitive content, it was found that both decision and reaction time increased

Choice Reaction Times in Depressive States

British Journal of Social and Clinical Psychology, 1976
An 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 ...

Some Experiments on Simple and Choice Reaction Time.

Journal of Experimental Psychology, 1967
Abstract : The report concerns four problems on simple and choice reaction time (RT). First, in Experiments 1 and 2, the suthors examine the role of time estimation in the manipulation of responses in simple reaction time experiments by means of payoffs and information feedback.

Models for Choice-Reaction Time

Psychometrika, 1960
In 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.

Choice Reaction Time Modifiability in Dementia and depression

International Journal of Neuroscience, 1985
The effects of cognitive impairment resulting from either dementia of the Alzheimer type (DAT) or major depression (pseudodementia) on choice reaction time were examined in two conditions hypothesized to influence group performance selectively. Elderly controls had shorter reaction times than depressed patients who, in turn, were faster than dementia ...

What is the Basis of Choice Reaction-Time ?

Ergonomics, 1971
In an 8-choice reaction task times for responses by the ring and middle fingers were found to be substantially longer than those for responses by the index and little fingers. Supplementary experiments showed that the inequalities were not due to motor factors but rather to perceptual features which affected the ease with which the positions of signals
