Abstract : This report presents a summary of work on visual and auditory signal recognition. The visual studies included effects of chromatic adaptation on color naming, and on saturation estimates, ROC curves developed over the course of dark adaptation, and studies of the Bezold-Brucke hue shift. The studies of auditory detection included work on lateralization of sound, on masking level differences (MLDs for tone and narrow-band noise, effect of noise bandwidth on detection of a tonal signal, effect of punishment on performance in a detection task, and a series of studies of electrical and mathematical models of auditory detection.
