Reaction time as a function of perceptual bias, response bias, and stimulus discriminability.
The effects of stimulus discriminability, stimulus frequency, and response frequency were examined in a choice reaction time (RT) task. Two levels of response frequency ratio (i.e., one of two responses occurred two or five times as often as the other) were combined with three levels of stimulus configuration. Configuration was defined by the spatial distance between three stimulus lights. Perc...
متن کاملAn electromyographic investigation of the effect of stimulus-response mapping on choice reaction time.
The activity of the agonist muscles was recorded during the performance of a two-choice visual reaction time (RT) task in which the compatibility of the stimulus-response mapping was manipulated. Correct trials were distinguished according to whether or not the activation of the agonist of the required response was preceded by an activation of the agonist of the nonrequired response. Double act...
متن کاملA choice reaction time analysis of spatial frequency discrimination.
Simple reaction time to the onset of sinewave gratings was measured as a function of spatial frequency in two observers. These results are compared to the choice reaction time required for the observer to correctly discriminate the spatial frequency of two gratings flashed sequentially. Grating contrast was either 0.75 or 1.5 logarithmic units above the detection threshold for each spatial freq...
متن کاملStimulus information as a determinant of reaction time.
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 alt...
متن کاملReaction Time and Movement Time as Measures of Stimulus Evaluation and Response Processes
Reaction time has been divided into the time to initiate a response (RT) and the time to execute the motor response (MT) in many chronometric studies of intelligence. Our purpose was to determine which cognitive processes are reflected by RT and MT. To accomplish this, the latency of the P300 wave of the event-related potential was recorded concurrently with RT and MT measures in three experime...
