In the typical reaction-time experiment, S's reaction time is greater when he has to respond differentially to one of two equally probable stimuli instead of to just one stimulus. In fact, Merkel (2), using one to ten alternatives, has demonstrated that when S has to respond to one stimulus chosen from a number of equally probable alternatives, his reaction time increases with the number of alternatives. The fact that S's response to stimulus A takes more time when A is one of several rather… Expand

The locus of stimulus probability effect in choice reaction time
A choice reaction time experiment was conducted in which subjects were to respond with one response to either of two stimuli, S1 and S2, and with another response to a third stimulus, S3. The stimuliExpand
Choice Reaction Time as a Function of Stimulus versus Response Relative Frequency of Occurrence
TLDR
This work has studied choice reactions to alternatives of unequal frequencies of occurrence in tasks with a 1 : 1 correspondence between stimuli and responses to find the answer to which variable is critical in determining the reaction time. Expand
Choice Reaction Times for Skilled Responses*
Two kinds of choice reaction time experiments are reported, both of which make use of a highly overlearned sensori-motor response. When a response is required for each stimulus presented, no increaseExpand
Stimulus Categorization and Response Time
TLDR
Two experiments were conducted in which the stimulus set was mapped onto the response set in a many-to-one-fashion and RT varied with the number of independent disjunctively combined attributes used to designate the critical category. Expand
Stimulus probability and choice reaction time
Two experiments, in which three stimuli were paired with two responses in a 2:1, 1:1 arrangement, showed choice RT to be a decreasing function of the relative frequency of stimulus occurrence whenExpand
An informational approach to reaction times.
TLDR
Threshold appears to be the smallest stimulus capable of transmitting the quantity of information delta H, from stimulus to subject, which is, information summation replaces energy summation. Expand
Prediction of choice reaction time from information of individual stimuli
A model is developed to predict the reaction time to stimuli using information content of the individual stimuli. Review of previous research in the area showed inconsistencies due possibly to theExpand
A study of disjunctive reaction times
To decide what to do means to choose an appropriate response to a situation. In the simplest case, the situation may be one of several stimuli, to each of which there is a “correct response.” OtherExpand
Reaction times to new versus repeated signals in a serial task as a function of response-signal time interval
Summary Previous experiments showed that serial choice RT is longer on the trials where the stimulus is different from the preceding one. The influence on this phenomenon of the duration of theExpand
Stimulus versus response probability effects in choice reaction time
The effects of stimulus and response probability on choice reaction time (RT) were independently investigated. In different conditions, two sets of three stimuli of probabilities of.1, .3, .6 and.3,Expand

On the Rate of Gain of Information
TLDR
The principal finding is that the rate of gain of information is, on the average, constant with respect to time, within the duration of one perceptual-motor act, and has a value of the order of five “bits” per second. Expand
