The hypothesis that responding to hecklers would produce more agreement with a speaker than not responding, stemmed from commodity theory (Brock, 1968). One hundred twenty‐one introductory speech students participated in what they were told was a “speech workshop” (not a psychology experiment). Two types of responding to live hecklers were used: In one, the speaker responded in a calm, relevant manner; in the other, she responded in an upset, irrelevant manner. In a third condition, the speaker did not respond to the heckles. There were two additional conditions: One in which the speaker responded to interruptions, and a further control in which there were neither heckles nor interruptions.
