Abstract
ABSTRACTThe purpose of this study was to investigate the relationship between avoidance behavior of human subjects and gastric acid changes. An intragastric radio transmitter was employed to record stomach acid secretion rates. The subjects were divided into two groups. The members of the Response‐Contingent (RC) group were led to believe that they would be able to avoid a strong electric shock during the Test phase of their session. In the No‐Response (NR) group, subjects were correctly told that they would be without means of avoiding shock. The results demonstrated that (a) subjects could not be differentiated according to gastric acid secretion rate strictly on the basis of whether or not they made an avoidance response to an aversive stimulus; (b) a non‐significant majority of subjects in both groups exhibited decreased gastric acid secretion rates during the Test phase; and (c) both groups showed a significantly faster rate of gastric acid secretion during the Post‐Test phase than during the Test condition.
