EFFECTS OF VARIATION IN VISUAL AND AUDITORY STIMULATION ON GASTROINTESTINAL MOTILITY.
Technical rept. no. 12,
INDIANA UNIV BLOOMINGTON
Pagination or Media Count:
The purpose of this experiment was to investigate the effects of three different stimulus conditions on gastrointestinal motility as measured by electrodes on the surface of the abdomen. The 16 Ss were each run for two 40 min. sessions, during which they were instructed to lie quietly on a cot. Amplitude differentiated between a group that received diffuse stimulation and groups that received normal stimulation and no stimulation, with the former showing greater activity throughout the session. The increase in gastrointestinal activity for Ss in the diffuse stimulus group is attributed to the novelty and ambiguity of the stimulus situation. Author
