Effects of reward distribution and performance feedback on competitive responding

To implement competitive contingencies, one must select a distribution of unequal rewards and a schedule of feedback for competitors regarding one another's performance. This study investigated three bases for distributing rewards and two performance feedback conditions. Pairs of college students competed over a series of 2-min contests in which the competitive response was a knob pull. A sum of money was divided using a proportional distribution or one of two fixed reward distributions. In the proportional distribution, a subject's proportion of the sum was his or her proportion of the total number of responses. The two fixed distributions were divisions of 100%/0% or 67%/33%. 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. In the two feedback conditions, cumulative responses by each subject were either shown to both subjects during the contest or were not shown. The proportional distribution was clearly superior to either of the fixed distributions in number of responses produced across contests. The proportional distribution with feedback produced the largest number of competitive responses, and the 100%/0% distribution without feedback produced the smallest number. Differences among distributions typically emerged only during later blocks of contests. Fixed distributions of rewards often produced decelerating rates of responding, with losing competitors ending the contests before they were completed. Response-rate decreases were greatest for pairs in which the 2 subjects differed most in their response rates and proportion of wins. The presence of feedback had a small effect, increasing responding for some pairs in the 100%/0% distribution. Performance patterns were interpreted in terms of the consequences arranged for the individual participants by the reward distributions and differences in performance between competitors.     

Audit responses: responses maintained by access to existing self or coactor scores during non-social, parallel work, and cooperation procedures

Human subjects, mostly between 11 and 16 yr old, matched to sample for points that were exchangeable for money. An audit response was defined as a response maintained by allowing a subject access to an existing score on his own (self audit) or a coactor's (coactor audit) performance. In Experiment I, changes from non-social procedures (no coactor) to social procedures (coactor present) increased self and coactor audits. Since both types of audits occurred at about the same rates during cooperation and parallel work procedures, the increases did not depend on the subjects' response interactions. Although Experiment I did not demonstrate that subjects were comparing scores, the frequent occurrence of each kind of audit within a brief time period (interpersonal audit) did indicate that it was reinforcing to have both scores at the same time. These interpersonal audits suggested that the coactor's score increased self audits during social procedures. Experiment II supported this notion: relative to a non-social procedure, self audits increased more during a parallel work procedure when the coactor's score was accessible than when it was not accessible. Thus, increases in other behaviors that occur in the presence of a coactor, i.e., social facilitation, may also result from or be increased by providing a coactor's score.     

Effects of the difference between self and coactor scores upon the audit responses that allow access to these scores

An audit response allows access to an existing score from a subject's own performance (self audit) or from his coactor's performance (coactor audit). A previous study found that social stimuli (coactor present) increased audits relative to a non-social (no coactor) condition. The increase, designated a social-stimulus effect, was found to be due more to the coactor's score than to his mere presence. This finding suggested that the difference between self and coactor scores might affect the size of the social-stimulus effect. In the present study, six pairs of human subjects matched-to-sample for points that were exchangeable for money. During a session, matching-to-sample problems were distributed so that a subject's score was ahead, behind, or about even with his coactor's score. The even condition produced the largest social-stimulus effects, i.e., the most audits that could not be attributed to non-social variables such as time or number of problems. The even condition may have produced the largest social-stimulus effects because it was the only condition where the major social reinforcer (being ahead) could be both present or absent and, consequently, the even condition was the only one where audits had a discriminative function with respect to the presence of the major social reinforcer.     

Causal attribution of success and failure as a function or authoritarianism and sex.

We predicted that authoritarian actors would engage in defensive attribution, and authoritarian observers would derogate the other, to a greater extent than egalitarian perceivers. 48 male and 48 female college students were run in pairs of same sex and authoritarianism. A set of easy anagrams was given to subjects in success conditions and difficult anagrams to those in failure conditions. Each subject rated own outcome and other outcome in terms of internal factors of ability and effort, and external factors of task and luck. We found that authoritarian actors were more internal than egalitarian actors only in the condition own success-other's failure. Authoritarian observers, as compared to egalitarians, were more external for other's success and more internal for other's failure only when own outcome was successful. It seems that authoritarian perceivers exaggerate their abilities and derogate the other only when they are clearly in a superior position vis-a-vis the other. There were no sex differences as a function of outcome and authoritarianism.     

Contest experience and body size affect different types of contest decisions

This study examined the relative importance of contest experience and size differences to behavioral decisions over the course of contests. Using a mangrove rivulus fish, Kryptolebias marmoratus, we showed that although contest experience and size differences jointly determined contest outcomes, they affected contestants’ interactions at different stages of contests. Contest experience affected behavioral decisions at earlier stages of contests, including the tendency and latency to launch attacks, the tendency to escalate contests into mutual attacks and the outcome of non-escalated contests. Once contests were escalated into mutual attacks, the degree of size difference affected the fish’s persistence in escalation and chance of winning, but contest experience did not. These results support the hypothesis that contest experience modifies individuals’ estimation of their fighting ability rather than their actual strength. Furthermore, (1) in contests between two naïve contestants, more than 60 % of fish that were 2–3 mm smaller than their opponent escalated the contest to physical fights, even though their larger opponents eventually won 92 % of escalated fights and (2) fish with a losing experience were very likely to retreat in the face of an opponent 2–3 mm smaller than them without escalating. The result that a 2–3 mm size advantage could not offset the influence of a losing experience on the tendency to escalate suggests that, as well as depending on body size, the fish’s physical strength is influenced by other factors which require further investigation.     

Testosterone and cortisol responses to competitive fighting in human males: A pilot study

Serum testosterone and cortisol levels were measured by radioimmunoassay in 14 young male judo competitors, in samples taken 10 minutes before and 45 minutes after two different procedures. The first involved physical exercise and the second competitive fighting. Both procedures were of 5 minutes duration and sessions took place at the same time (between 10:00 A.M. and 12:00 P.M. local time) but on different days. Comparing the two situations over all subjects revealed that testosterone increased after exercise and decreased slightly after Competition. Between subject comparisons suggested that contrary to previous claims, winning or losing did not significantly change the testosterone and cortisol levels. Comparisons of subjects who were members of the Regional Team with individuals who were not part of that group confirmed that members increased their testosterone levels after competition, whereas the nonmembers showed a significant decrease. Moreover, success of the individuals, in their sporting record, correlated positively and significantly with the changes of testosterone observed during the competition. These preliminary results suggest that previous personal experience of success can influence the pattern of the psychoendocrine response to a contest situation.     

Social motives and strategic misrepresentation in social decision making

In 4 experiments, the authors studied the influence of social motives on deception and strategic misrepresentation. In a newly developed information provision game, individuals faced a decision maker whose decision would affect both own and other's outcomes. By withholding information or by giving (in)accurate information about payoffs, participants could try to influence other's decision making. Less accurate and more inaccurate information was given when the decision maker was competitive rather than cooperative (Experiment 1), especially when participants had a prosocial rather than selfish value orientation (Experiments 3 and 4). Accurate information was withheld because of fear of exploitation and greed, and inaccurate information was given because of greed (Experiment 2). Finally, participants engaged in strategic misrepresentation that may trick competitive others into damaging their own and increasing the participant's outcomes.     

Hormones and competitive aggression in women

This study used diaries of competitive interactions to explore the relationship between hormones and competitive aggression in women. Thirty women completed approximately 10 diary entries each. In each entry, the women described a recent competitive interaction they had engaged in and noted whether it was expressed aggressively or through other tactics. Each woman received a score for the fraction of her competitive interactions that were expressed using physical aggression, verbal aggression, nothing overt, and so on. Hormones (total testosterone, free testosterone, androstenedione, estradiol, and cortisol) were measured in serum early in the follicular phase. Results indicate that women with low levels of androstenedione and total testosterone were less likely to express their competitive feelings overtly, while women with high levels of androstenedione were more likely than other women to express their competitive feelings through verbal aggression. Estradiol was unrelated to competitive tactics, but women with high estradiol levels reported fewer competitive interactions over athletics than did other women. Aggr.

Avoidance of risk as a determinant of cooperation

Pairs of subjects could either cooperate or respond on a lower paying individual task. Whenever both subjects chose to cooperate, either subject could make a response that took $1.00 of the other's earnings. In Exp. I, a stimulus signalled when a “take” response had been made. Either subject could avoid the loss by switching to the individual task within 5 sec after the stimulus appeared. Rates of cooperation were high when losses could be avoided but decreased again when the avoidance condition was removed. In Exp. II, a response prevented “takes” from occurring for a specified time interval after the response. This procedure also maintained cooperation. When each avoidance response subtracted from earnings, both avoidance responding and cooperation were eliminated.     

Influence of win-loss ratio on performance,satisfaction and preference for opponents

Hypotheses about the preference for opponents in competitive situations, about performance under various win-loss ratios, and about task and opponent satisfaction under various win-loss ratios were tested. A 5 × 5 latin square with four replications and a repeated measure factor of trials was the design used with 20 female college students as subjects. The five different win percents were W₁₀, W₃₀, W₅₀, W₇₀, and W₉₀. A manipulative maze task was used with subjects receiving 20 trials against each of five confederate opponents. Results indicated that (a) when a person knows little or nothing about her ability level she initially prefers to compete with opponents of low ability but with each subsequent contest opponents of higher ability levels are preferred; (b) subjects performed better in the W₅₀ condition; (c) task satisfaction is higher when the percent of wins is equal to or greater than the percent of losses; and (d) opponent satisfaction is greater for opponents who perform equal to or better than the subject.     

Specification of variables predictive of victories in the sport of boxing

Compared to other sports, very little research has been conducted on which variables can predict victory in the sport of boxing. This investigation examined whether boxers' age, weight change from their preceding contest, country of origin, total number of wins, total number of losses, performance in their preceding contest, or the possession of a championship title was predictive of a winning performance in a given bout. A 1-mo. sample of male professional boxing records for all contests held in the USA (N = 400) were collected from the BoxRec online database. Logistic regression analysis indicated that only boxers' age, total number of wins and losses, and the performance in the preceding contest predicted significant variance in outcome.     

When do people bet on their selves? The role of global self-concepts in decision making

Previous research suggests that behavior is generally predicted by specific self-concepts but not global self-concepts. A study was conducted to examine the conditions under which global conceptions of self are predictive of decision-making. Participants were given the opportunity to bet lottery tickets on their performance in the “Utah Challenge” competition. Both global and specific self-concepts independently predicted betting on specific known contests and betting on a contest that was unknown. Global but not specific self-concepts independently predicted betting on a multi-faceted contest. Mediation analyses suggest that self-concepts guide decisions by influencing the perceived likelihood of success. Participants’ were more overconfident about their chances of winning when a task was unknown rather than familiar.     

THE DISCLOSURE-LIKING RELATIONSHIP

Two experiments were conducted to investigate the effects of a perceiver's own disclosure on attraction for self-disclosing others. In Experiment 1, female undergraduates selected two topics and disclosed information on them to a confederate partner. This disclosure occurred either before or after the confederate disclosed information on three different topics that were either high or low in intimacy. Based on self-perception theory, it was predicted and found that intimacy of the subject's self-disclosure would be positively correlated with attraction for the confederate when the subject disclosed before her partner but not when she disclosed after her partner. A second prediction that subjects would be attracted toward a highly intimate partner only if they had previously disclosed was not confirmed. Instead, attraction for the confederate was greater when she had disclosed before the subject and when she had disclosed intimately. Experiment 2 varied the intimacy of the response of a partner to the subject's initial self-disclosure and whether this response dealt with the same topics or different topics. It was found that attraction was greater for an intimate than a nonintimate partner when topics for disclosure were the same. When disclosure topics were different, there was no significant difference in attraction for the intimate and nonintimate partner. Results are discussed in terms of their implications for the disclosure-liking hypothesis.     

Subjected Subjects? On Judith Butler's Paradox of Interpellation

Judith Butler's theory of the constitution of subjectivity conceptualizes the subject as a performative materialization of its social environment. In her theory Butler utilizes Louis Althusser's notion of interpellation, and she critiques the constitutive paradoxes to which its tautological framing leads. Although there is no pre‐existing subject, as it is constituted in the turn to the interpellative hail, Butler nonetheless theorizes a guilt and compulsion acting on an “individual” that compels his or her turn to answer the hail. There is a price to pay for subjectivity in Butler's schema: the reprimand of the interpellative law that punishes at the same time as it constitutes. But a return to Althusser's text finds that he does not rely so much on coercion and guilt in his explanation of the subject's answer to the hail. Althusser can instead be read as suggesting that we are already an instantiation and enactment of power‐ideology and, to paraphrase Michel Foucault, are already the principle of our own “subjection.” This contests the notion that we are in any way compelled to submit to an external, punitive force to become subjects. As subjects, we are always‐already the embodiment of the field of society‐power‐ideology.     

Intensity and direction as dimensions of competitive state anxiety and relationships with competitiveness.

This study examined differences in intensity and direction of symptoms of competitive state anxiety in high and low competitive subjects from the sports of rugby union, basketball, soccer, and field hockey. The 69 men were dichotomized via a median-split into high and low competitive groups based on their scores on the Sport Orientation Questionnaire. All subjects completed a modified version of the Competitive State Anxiety Inventory-2 30 minutes prior to competition. This inventory included the original intensity scale plus a direction scale on which subjects rated the extent the experienced intensity of each symptom was either facilitative or debilitative to subsequent performance. There were no significant group differences on intensity of cognitive anxiety or of somatic anxiety or on direction of somatic anxiety; however, the highly competitive group of 34 subjects reported their anxiety as more facilitative and less debilitative than the low competitive group (n = 35). This supports the proposal that sports performers' directional perceptions of their anxiety symptoms may provide further understanding of the competitive state-anxiety response.     

Heart rate and blood pressure responses to a competitive role‐playing game

The effects of the outcome of competitive encounters on physiological parameters have been studied, especially testosterone levels, but hardly on other systems that, however, present a high sensitivity to stress. This study assessed the effect of a competitive game on heart rate (HR) and blood pressure (BP) in a sample of university students. In addition, the influence of anxiety and attributions of the outcome was also explored. Only winners significantly showed a rise in HR during the competition followed by a decrease along the posttask phase in addition to more internal attributions. On the contrary, the average HR for losers during the competition was lower compared with their baseline values. No differences depending on the outcome were found in BP. The cardiovascular response as well as the subjective interpretation of the outcome suggest a more active strategy employed by winners vs. a more passive strategy of losers. Future studies should specifically investigate the importance of coping strategies for psychophysiological adaptation to contests and for the outcome reached. This would permit an advance in the understanding of the role of individual differences in the processes of stress and in associated diseases. Aggr.

Informational determinants of females' self-attributions and observers' judgments of them in an achievement situation.

A female (A) received feedback about both her own and a male or female other's (B's) performance on an achievement task, and then estimated the likelihood that she and B possessed each of several attributes related to competence, likeableness, and physical attractiveness. The situation was witnessed by a male or female observer who then judged B's attributes and predicted A's and B's ratings of one another. A formulation of social inference processes developed by Gollob was used to identify and compare the informational cues used by actors and observers in making these attributions. The contributions of these cues depended substantially on the type of attribute being inferred, the judge (A or the observer), and whether the judgment was made of A or of B. A's behavior (i.e., her performance on the achievement task) contributed less to her self-attributions than it did either to her predictions of how B would rate her or to observers' actual judgments of her attributes. A's self-attributions tended to be relatively more influenced by her experiences before participating in the experiment. Whereas A appeared to use B's performance as a comparative standard when judging her own competence and expected B to do likewise, observers did not use B's performance in this manner when judging A. Moreover, A did not use her own performance as a standard when judging attributes of B. The article discusses theoretical implications of these results for attribution and self-perception processes.     

Unequal reinforcer magnitudes and relative preference for cooperation in the dyad

College-student subjects, who were paired with a confederate, chose to respond either independently or cooperatively for money reinforcers. The subject's relative preference for cooperation was assessed by a procedure (analogous to the psychophysical method of limits) in which response choice was monitored as reinforcer magnitude for one response mode was systematically varied while the other remained constant. Relative preference for cooperation was assessed when the confederate's payoff for cooperation was greater than the subject's (Experiment I) and when the confederate's payoff for independent responding was less than the subject's (Experiment II). For some subjects, changes in the confederate's reinforcer magnitudes resulted in shifts in relative preference for cooperation, which reduced the earnings differences, even though these preference shifts reduced the subject's absolute earnings. For those subjects for whom within-dyad differences in reinforcer magnitude produced no effect, a changeover button was introduced that allowed the subject to eliminate the payoff difference without reducing her own earnings; some subjects used this changeover button to eliminate earnings differences. Thus, the behavior of subjects varied, in part, as a function of reinforcer magnitudes provided for the confederate.
