Absolute sensitivity to white noise under auxiliary visual stimulation1
Absolute sensitivity to white noise was measured with the O in the dark, in constant illumination, and in the dark but with sound-synchronized flashes of light at three different intensities. A confidence rating procedure was used, and the results were analyzed in terms of the theory of signal detectability. There appeared to be no consistent effect of auxiliary visual stimulation on absolute auditory sensitivity for the four Os examined.
