Ongoing temporal coding of a stochastic stimulus as a function of intensity: time-intensity trading.
Stimulus-locked temporal codes are increasingly seen as relevant to perception. The timing of action potentials typically varies with stimulus intensity, and the invariance of temporal representations with intensity is therefore an issue. We examine the timing of action potentials in cat auditory nerve to broadband noise presented at different intensities, using an analysis inspired by coincide...
متن کاملThe relationship between latency of auditory evoked potentials, simple reaction time, and stimulus intensity.
The effects of loudness on the latency of evoked potentials and on simple reaction time were compared. It was found that both reaction time and the evoked-potential latency increases with decreasing stimulus intensity. However, different slopes of the curves were found. This is explained in terms of the arousal effect of loud auditory stimuli.
متن کاملthe effect of environmental color on simple reaction time to auditory stimulus
colors influence mood and mental state of human beings and since manis constantly in touch with colors, great important will be attached to thecolors. exercise is also associated with different colors and is performed inan environment full of different colors. also, one of the important factorsaffecting athletes' success is response to the stimulus. considering theimportance of color and r...
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 کاملSimple reaction time as a function of time uncertainty.
An earlier study (3) showed that simple reaction time (RT) varies 'with S's uncertainty about time of stimulus occurrence. This time uncertainty is a function of both the mean duration of the time (foreperiod) between a warning signal and the stimulus and the variability within the series of foreperiods. Foreperiod variability adds uncertainty directly and mean foreperiod is important since S's...
