Monaural auditory adaptation as measured by simple reaction time

Simple 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...

the 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...

Binocular summation of chromatic changes as measured by visual reaction time.

We determined visual reaction times to monocular and binocular changes in the luminance of isochromatic stimuli and to monocular and binocular changes in the color of isoluminant stimuli. Two isoluminant color changes were tested: chromatic variations along the red-green axis of Boynton's (1986) two-stage color vision model and chromatic variations along the yellow-blue axis of the same model. ...

Performance of alternative simple imputation methods, as measured by correlation

Efficiency and internal noise for detection of suprathreshold patterns measured using simple reaction time

Studies of the detection of simple visual patterns at threshold contrast have found that human performance is limited by the addition of internal noise and by the sub-optimal sampling efficiency of the visual system. Many common visual tasks require the detection of a signal having a contrast well above threshold, and we sought to measure the internal noise and sampling efficiency for such sign...
