This study allowed subjects to audit each other's responding during a series of competitive contests. Six pairs of female college students competed in 3-min contests in which the competitive response was a knob pull. A sum of money was divided using a proportional distribution or a 100%/0% reward distribution. In the proportional distribution, a subject's proportion of the sum was her proportion of the total number of responses. Also, in every contest either subject could make a response that would end the contest prematurely and give both subjects the same amount: a sum equal to 33% of the competitive total. Each subject could press either or both of two audit buttons that displayed her own and the other's response total for 10 s. Results replicated earlier findings in showing the superiority of the proportional distribution in total number of competitive responses made. No subject audited continuously, and only 1 audited most of the time. Most audits were interpersonal, including both own and other's scores. Auditing typically was more frequent in 100%/0% contests in which subjects were more likely to stop the contest when they were far behind. Winners were more likely to audit than were losers. Competitive response rates increased when the differences revealed by audits were small and decreased when they were large. Overall audit patterns were consistent with the view that feedback as ''news'' is more often sought when it can lead to improved outcomes.Key words: competition, auditing, reinforcement contingencies, reward distributions, performance feedback, knob pulls, college studentsCompetitive reward contingencies are ubiquitous in education, business, and sports in motivating performances of participants in a group. With competitive contingencies, rewards are distributed unequally based on relative performance. Competitive contingencies are frequently compared with cooperative or individual contingencies as alternative reward structures. When the object is to choose the reward structure that produces the best total effort by the group (e.g., problems solved, products produced), results from a large body of research reveal cooperation to be more often superior when the comparison involves a range of task types (for reviews, see Johnson,
