Value Judgments: Testing the Somatic-Marker Hypothesis Using False Physiological FeedbackUniversity of Kansas, dbatson{at}ukans.edu

University of Kansas Damasios somatic-marker hypothesis claims that people rely on somatic markersphysiological responses to situations of gain or lossto make value-relevant decisions, not simply on cool reason. To test this hypothesis, undergraduates were presented with false physiological feedback as they listened to audiotapes describing situations threatening two values, freedom and equality. They were then asked to make decisions that implicated these values. Decisions favored whichever value had received stronger feedback while listening to the value-threatening situations. Feedback did not, however, affect judgments about the relative importance of the values in general; these judgments were apparently based on cognitive retrieval from memory of a stored value hierarchy, which alsoand independently affected the value-related decisions. These results supported the somatic-marker hypothesis.
