[Value of cumulative electrodermal responses in subliminal auditory perception. A preliminary study].
This exploratory study examined the usefulness of averaging electrodermal potential responses for research on subliminal auditory perception. Eighteen female subjects were exposed to three kinds (emotional, neutral and 1000 Hz tone) of auditory stimulation which were repeated six times at three intensities (detection threshold, 10 dB under this threshold and 10 dB above identification threshold). Analysis of electrodermal potential responses showed that the number of responses was related to the emotionality of subliminal stimuli presented at detection threshold but not at 10 dB under it. The data interpretation proposed refers to perceptual defence theory. This study indicates that electrodermal response count constitutes a useful measure for subliminal auditory perception research, but averaging those responses was not shown to bring additional information.
