Abstract

The purpose of this study was to investigate the effect of certain meaningful and non-meaningful auditory stimuli on the human pupillary response. An improved method of film processing which would permit the use of less expensive film was developed. The experiment was administered to ten normal hearing and ten hard of hearing young adults. Significance was found between levels of the 15 dB above and 5 dB below threshold presentation and between groups by levels. An additional level of 100 dB was presented to the normal hearing group. It was found that the normals respond to the 100 dB presentation in the same manner in which the hard of hearing responded to the 15 dB presentation. NO significant difference was found to exist between groups, typos of auditory stimuli (treatments) or groups by treatments. It was concluded that the auditory pupillary reflex does not occur as often at was indicated by the literature.
