Abstract : The report summarizes the work performed and data collected in the Psychophysiology section of the Human Factors Laboratory, New York University, from 1 April 1971 through 31 March 1972. Six experiments were conducted. The first study was concerned with visual evoked potentials (VEPs) and detection performance under conditions of four-digit overprinting. In the second experiment overprinting was studied again in a situation in which the third stimulus in the digit string was now of higher luminance than the others. Experiment III studied visual and auditory cortical evoked potentials under conditions of single and bimodal stimulation. The fourth experiment was concerned with the question of whether increasingly intense auditory stimuli would produce evoked responses in the visual area. Experiments V and VI were conducted to study the effects of geometric form upon the VEP. In experiment V the stimuli were simple lines oriented three different planes and in experiment VI VEPs to two different geometric forms (square and triangle) were studied. (Author)
