Signal-detection analysis of group decision making

How effectively can groups of people make yes-or-no decisions? To answer this question, we used signal-detection theory to model the behavior of groups of human participants in a visual detection task. The detection model specifies how performance depends on the group's size, the competence of the members, the correlation among members' judgments, the constraints on member interaction, and the group's decision rule. The model also allows specification of performance efficiency, which is a measure of how closely a group's performance matches the statistically optimal group. The performance of our groups was consistent with the theoretical predictions, but efficiency decreased as group size increased. This result was attributable to a decrease in the effort that members gave to their individual tasks rather than to an inefficiency in combining the information in the members' judgments.     

Immediate attributional effects of success and failure in the field: Testing some laboratory hypotheses

Investigated how team success and failure are attributed to dispositional and situational factors as a function of immediate outcome of the group performance, past success of the team, and individual performance of team members within the group. 150 Little League baseball players' attributions for the team's outcome were taken separately with regard to team- and self-factors immediately after the conclusion of a game. The results reveal that success, independent of the margin of victory, is primarily assigned to effort and ability, while clear-loss is attributed to both effort and task difficulty. Conversely, bare-loss is seen to be mainly due to task difficulty and secondarily to low effort. The results are interpreted as supporting the notion of ego-centered causal judgments, but not necessarily the motive to enhance one's self, on the basis of the new proposition that effort has a different attributional meaning in the cases of success and failure; when losing effort is treated as an external factor, and when winning, effort tends to be interpreted as an internal factor. No differences with respect to attributions exist between individual players who perform poorly and those who excell within the team performance.     

Necessary versus sufficient causal schemata for success and failure

197 subjects judged the perceived presence or absence of ability or effort, given information about task outcome (success or failure), the difficulty of the task (easy, intermediate, or difficult), and the state of the complementary cause (effort or ability). The data revealed that a multiple sufficient causal schema is used to explain common events. That is, the presence of ability or effort is perceived as enough to produce success at an easy task, while the absence of ability or effort is perceived as sufficient to result in failure at a difficult task. On the other hand, a multiple necessary schema tends to be employed to explain uncommon events. Success at a difficult task is believed to require both ability and effort, while failure at an easy task tends to be perceived as caused by low ability and low effort. In addition, there were disparities in the causal judgments for success and failure: failure outcomes are more likely to elicit a multiple sufficient schema. Further, in achievement-related contexts ability and effort are perceived as negatively covarying causal determinants of typical successes and failures. In addition to supporting hypotheses from attribution theory, the data shed further light upon the perceived determinants of success and failure, and demonstrate the influence of cognitive structures on achievement-related causal judgments.     

Effects of team outcome on children's self-perception: Little League baseball

Abstract.— To determine how children use various attributional categories in making judgments about themselves as a function of team performance outcomes, answers were sought to the questions of how invariant children's perceptions of their characteristics are, and how they expect social agents to judge them under the various outcome conditions of team performance. Subjects were 300 Little League baseball players. Team failure did not decrease the players' judgments of their own internal qualities (ability and effort) but did decrease their judgments of those of the team. In addition, the players judged themselves and expected social agents (coach and spectators) to judge them as being unlucky and having a difficult task following team failure. Theoretical implications of the results were discussed.     

Foreseeability and self-interest as moral judgment factors with normal and acting-out adolescent boys

Thirty-two male adolescents participated in a study of moral judgment and its relationship to social functioning. Half of the subjects were selected for frequent acting-out, aggressive behavior, and half were selected from regular eighth-grade classes and matched for intelligence. The moral stories featured good intentions with bad outcomes and varied as to whether or not the outcome was foreseeable and in the actor's self-interest. Subjects judged the actor, attributed judgments to adults, and casually explained the outcome. The difference in judgments between foreseeable and nonforeseeable actions was greater for “normal” subjects. Furthermore, although normal subjects judged foreseeable actions more harshly than acting-out subjects, the reverse was true for nonforeseeable actions. Judgments attributed to adults were harsher than subjects' own judgments, and this difference was greater for acting-out subjects. Causal attributions (personal vs. situational) and other reasoning related strongly to the foreseeability and self-interest factors but not to subject group.     

The role of ability and effort in attributions for sport achievement1

In an initial attempt to assess the applicability of Weiner's (1972) attribution model to sport-related behavior, the effects of ability (high versus low), effort (high versus low) and outcome (success versus failure) on causal attributions were investigated. After riding a bicycle ergometer, subjects were asked to attribute the cause of their increased or decreased performance to ability, effort, task difficulty and/or luck. The results indicated that successful outcomes were attributed to both ability and effort and that unsuccessful outcomes were attributed to a lack of ability but not a lack of effort. While the task was seen as easier following success, the perception of low effort mediated this relationship. The results were interpreted to support a situationally specific conceptualization of sport achievement. First, whereas a motivational bias appears to preclude low ability attributions in intellectual pursuits, such is not the case with a novel physical task contingent on strength and muscular endurance. It was suggested that physiologically related ability may be viewed as relatively unstable. Second, relative to intellectual tasks, sport-related effort may be more salient and more quantifiable and may exert a greater influence on subsequent attributions for sport achievement. Finally, support was obtained for the assertions that affect is codetermined by both effort and ability and that expectancy discrepant performance is accounted for largely by perceptions of task difficulty.     

Testing some attribution-emotion relations in the People's Republic of China

We conducted a questionnaire study to test the generality of attribution-emotion relations to individuals in the People's Republic of China. Replications of prior findings of studies conducted with American subjects were reported: (a) High effort and success enhanced interpersonal evaluations when ability, effort, and outcome information were provided; (b) affective communications of pity, anger, and guilt were respectively used to infer low ability, lack of effort, and teacher as causes of failure; (c) effort and ability levels were inferred from the presence or absence of anger reactions; and (d) controllable causes of a broken social contract were expected to result in anger from others. Chinese and American respondents also indicated what situations would arouse the affects of anger, guilt, pity, pride, and shame. We found no evidence for the characterization of Chinese as (a) emphasizing effort over ability as a cause of achievement outcomes or (b) de-emphasizing the importance of personal achievement and stressing group goals and accomplishments.     

Self-observation of social behavior and metaperception.

In 3 experiments (Ns = 68, 72, and 101) the authors tested the hypothesis that the opportunity to observe oneself in social interaction increases the accuracy of metaperception (prediction of others' social judgments of oneself). Small groups were videotaped during a decision-making task, after which group members judged each other's social anxiety. Participants watched either the videotape of their group's interaction or a videotape of another group's interaction. After watching the videotape, participants predicted how they were judged by each member of the group. Results from the 3 experiments confirmed the hypothesis that self-observation increases the accuracy of metaperception. Presumably, self-observation provides objective information about one's behavior, which increases the ability to determine how one is judged by others, assuming self and others share meaning systems.     

Sex differences in assertive achievement patterns

Observations in mathematics and social studies classrooms were made of 40 sixth-grade children of average and high ability to investigate whether males and females differ in assertive achievement behavior. The prediction of less assertive achievement behavior for females than males was supported only among average-ability children. Particularly in social studies, average-ability females participated less in the classroom than average-ability males and either high-ability males or females. Average-ability females' deficit of assertive behavior became more pronounced as the behavior category increased in degree of assertiveness. High-ability females demonstrated a deficit only in the most assertive behavior category.     

奖赏结构与结果效价对儿童自我—他人成就归因与评价的影响

本研究旨在考察不同的奖赏结构和结果效价对儿童自我-他人成就归因、自我-他人奖赏评价的影响。实验采用2×2×2混合设计,其中自我-他人归因与评价为被试内设计。被试为小学五年级学生74名(男生36人,女生38人),实验通过解决一系列迷津测验来创设成功和失败情境。实验结果表明,奖赏结构对儿童自我-他人能力归因的影响、奖赏结构与自我-他人归因的交互作用对能力归因的影响、自我-他人运气归因均达到了显著性水平;努力和任务难度归因不显著;儿童对自我和他人的成就结果倾向于做能力和运气归因,较为忽略努力和任务难度在成就行为中的作用。     

Is self-sacrificial competitive altruism primarily a male activity?

This study explored the basis of self-sacrificial prosocial behavior in small groups. Seventy-eight undergraduates (39M, 39F) filled out a thirty-item personality scale and then participated in a "group problem-solving study" in which the monetary success of a three-person group depended upon one of its members volunteering to endure pain (a cold stressor test) and inconvenience (being soaked in a dunk tank). There were 13 groups consisting of two females and one male, and 13 groups consisting of two males and one female. Across groups, the behavior of the altruist was judged to be more costly, challenging, and important and he/she was liked better, rewarded with more money, and preferred as a future experimental partner. Groups containing two males showed more evidence of competition to become altruists than groups containing two females, and personality traits were more effective predictors of altruistic behavior in males than in females. We conclude that competition between males and "showing off" are key factors in triggering self-sacrificial altruistic behavior.     

Individual differences for sex differences in achievement attributions?

Past research has found a self-defensive bias in males and a self-derogatory bias in female achievement attributions. Dispositional explanations for these differences were examined in the present study. Subjects completed measures of Need for Achievement, Self-Esteem, Fear of Success, Attitudes Toward Women, and Androgyny. They later competed in same- or mixed-sex pairs on an anagram task which was prearranged in difficulty so that one subject clearly defeated his/her partner. Consistent with past research, males were more likely to attribute their outcomes to ability, and less likely to attribute their outcomes to effort and luck, than were females. Achievement motivation was the most consistently successful predictor of these sex differences.     

The Determinants and Consequences of Intragroup Respect: An Examination Within a Sporting Context1

Although the term respect is widely used in society, its determinants and consequences on group‐related factors are unclear. In 4 studies (2 pilot studies, validation study, main study), we examined these issues. In the main study, high‐level rowing crew members completed measures of respect, liking, and group identification pre‐ and post‐competition; and attribution items post‐competition. Although respect and liking did not predict team success, success was associated with subsequent levels of respect, but not liking. The effect of success on group identification was mediated by respect. Moderation analyses indicated that intragroup liking, but not respect, increased the likelihood of group‐serving attributions. Results highlight the determinants of respect and its role in group processes and outcomes, and distinguish respect from liking.     

Last and fast? – A gender-specific analysis of effort gains in swimming relay events across Olympic Games and World Championships during the past 20 years

Elite swimmers are individual athletes competing mostly on their own. However, when competing in a relay team, they are exposed to social influences possibly leading to effort gains compared to their individual performance. This study investigated effort gains in relay team members during 4 × 100 m freestyle races of Olympic Games and World Championships across the past 20 years. We assumed increasing effort gains in swimmers competing on later serial positions within their relay team since weaknesses in their performances can increasingly less be compensated by their teammates (social indispensability). Furthermore, we assumed a stronger gain in female athletes since females have been shown to be more affected by social indispensability then males. Using linear mixed modelling analyses, we additionally examined the moderating impact of the relay team outcome (i.e. medal-winning chance) on effort gains and indispensability effects while accounting for current team rankings at change-over. Except for the first swimmer, overall effort gains in relay performances were found as compared to performances in individual races during the same championship. Furthermore, these gains were close to equally distributed among both laps of the 100 m distance. However, even though effort gains are tending to be most pronounced for the last relay team swimmer we failed to detect any significant indispensability effect in our data set. Noteworthy, female swimmers showed larger effort gains when winning a medal (based on the current team rankings) was likely. In contrast, males showed effort gains irrespective of the serial order within the relay team and medal chance. Consequently, tentative recommendations are derived on how to line up a relay team.     

Self-Efficacy and Political Skill as Comparative Predictors of Task and Contextual Performance: A Two-Study Constructive Replication

This study examined how competition within teams influences which type of achievement goals employees adopt. We studied how dispositional learning-goal and performance-goal orientation interact with team-level competition and predict whether team members adopt state learning or performance achievement goals. State achievement goals, in turn, were proximal antecedents of two outcome measures: job-related self-efficacy and supervisory ratings of job performance. The participants were 502 employees and 55 supervisors. Results confirmed that competition was positively associated with state performance goals. Trait performance-goal orientation influenced whether competition was negatively associated with state learning goals. In highly competitive teams, trait performance-goal orientation was negatively related to state learning goals, whereas in less competitive teams, a performance-goal orientation was positively related to state learning goals.     

Selectional processes in causality judgment

Two experiments illustrate the way in which competition between potential causes occurs when subjects are asked to judge the extent to which an action is the cause of an outcome. In the first experiment, it was found that introducing occurrences of the outcome in the absence of the action reduced causality judgments, but this effect was attenuated if these outcomes were signaled by another stimulus. In the second experiment, a delay between the action and the outcome reduced judgments, but this could be abolished by inserting a stimulus between the action and the outcome. The results are discussed in terms of a view of causality judgment that assumes that such judgments are based on associations between the mental representations of the action and the outcome.     

Self-assessment and task performance

The present study tested the idea that the amount of effort expended in task performance is a function of the amount of uncertainty in one's ability level the resulting outcomes are expected to reduce. Two determinants of expected uncertainty reduction were manipulated: prior uncertainty about one's ability level and the diagnosticity of the task. Subjects first performed an initial task and then received fictitious feedback to manipulate their prior uncertainty. To induce low uncertainty, the feedback implied that the subjects are highly likely to have either low, intermediate, or a high level of ability. To induce high uncertainty, the feedback implied that the various ability levels were equally probable. Subjects then performed a task whose perceived diagnosticity regarding the ability under consideration was varied. As expected, subjects who were highly uncertain about their ability level performed better than subjects who were relatively certain they possessed either low, intermediate, or a high level of ability. Performance also improved with task diagnosticity, and the effect of task diagnosticity on performance was more pronounced when prior uncertainty was high than when it was low. Past research on the relationship between prior feedback and subsequent performance was discussed in light of the present results and a self-assessment model of achievement behavior.     

Achievement goal orientations,beliefs about sport success and sport emotions as related to moderate to vigorous physical activity of adolescents

Abstract

This study examined the relationships between achievement goals, beliefs about sport success and sport emotions with moderate to vigorous physical activity of Estonian adolescents. Three hundred and seventy five adolescents, aged 13–14 years, completed the Task and Ego Orientation in Sport Questionnaire and 7-day physical activity recall. Measures of the adolescent's orientation to work avoidance, focus on cooperation, beliefs about the causes of success and degree of satisfaction/interest specific to the context of sport and games were also included. Moderate to vigorous physical activity (MVPA) quartiles were determined and psychological measures for extreme activity groups were compared. A one-way ANOVA indicated that active males scored significantly higher in task orientation, motivation/effort, ability and enjoyment/interest whereas active females showed higher scores for cooperation and exercise enjoyment and lower deception and boredom compared with low activity groups. Correlation analysis revealed that in males, MVPA was related with task orientation, reported ability and motivation/ effort. For females, cooperation, and enjoyment of sport were positively and the amount of boredom was negatively associated with MVPA scores. Multiple regression analysis revealed that psychological measures explained only 14% (females) and 19% (males) of the variance in MVPA. It is concluded that for adolescent males and females, different psychological measures predicted MVPA behavior.
