Signal detection analysis of effect of white noise intensity on sensitivity to visual flicker.
Rating scale estimates of sensitivity to visual flicker were obtained from three subjects under 10 different intensities of auditory stimulation. Results indicated reliable "sawtooth"-like changes in sensitivity as a function of increasing intensity of white noise. No systematic and reliable changes were found in estimates of response bias. Theory and future research are discussed with reference to the possible contribution of cortical arousal.
