title: Multimedia stimulation for psychophysiological investigation.
abstract: This paper describes a multimedia approach to sensory stimulation in psychophysiological studies. High resolution colour images are presented to a subject by a Delphi stimulus program, controlled by a data acquisition system which concurrently records cognitive Event Related Potentials from the subject. The acquisition PC is linked to the stimulus PC using serial communications and requests slide material using a character based protocol. The sound card in the data acquisition system can present concurrent complex auditory stimuli for multimedia experiments.
