Social loafing on difficult tasks: Working collectively can improve performance.

Investigated the prediction that on difficult tasks (on which high levels of drive result in poor performance) working collectively would result in improved performance. A direct comparison of the methodologies of the social facilitation and social loafing paradigms was used. 48 undergraduate students were involved in the manipulation of 3 group conditions (alone, co-worker, and collective). The tasks involved 2 difficulty levels of computer mazes. Results indicate that Ss tended to perform better individually on simple tasks but better collectively on difficult tasks. Implications for integrating findings in social loafing and social facilitation are discussed. (24 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of group cohesiveness on social loafing and social compensation.

Individuals often engage in social loafing, exerting less effort on collective rather than individual tasks. Two experiments tested the hypothesis that social loafing can be reduced or eliminated when individuals work in cohesive rather than noncohesive groups. In Experiment 1, secretarial students typed both individually and collectively in simulated word-processing pools composed of either friends or strangers. In Experiment 2, dyads composed of either friends or strangers worked either coactively or collectively on an idea-generation task. Both studies supported the group cohesiveness hypothesis. Experiment 2 also suggested that individuals tend to engage in social compensation when working with coworkers who are low in ability. These findings are discussed in relation to S. J. Karau and K. D. Williams's (1993) Collective Effort Model. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of goals and feedback on performance in groups.

In the first study, 26 undergraduate pairs and 52 individuals worked on a perceptual speed task for 20 min to win prizes based on performance. The pairs set group goals and individual goals to be attained, whereas the individuals set only individual goals. Despite the equal levels of individual goals set, goal acceptance and performance were significantly higher for the pairs than for the individuals. A stepwise hierarchical regression analysis supported the contributions of goal acceptance and group goals to performance. In the second study, 50 undergraduate pairs were assigned a goal to be attained as teams on a perceptual speed task lasting 15 min. Group and individual task feedback, given after 7? min of work, significantly improved performance only for those subjects who were below target for either group or individual feedback, yielding interaction effects on performance. The implications of the findings for group goal setting, social loafing, and organizational effectiveness are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social loafing: A meta-analytic review and theoretical integration.

Social loafing is the tendency for individuals to expend less effort when working collectively than when working individually. A meta-analysis of 78 studies demonstrates that social loafing is robust and generalizes across tasks and S populations. A large number of variables were found to moderate social loafing. Evaluation potential, expectations of co-worker performance, task meaningfulness, and culture had especially strong influence. These findings are interpreted in the light of a collective effort model that integrates elements of expectancy-value, social identity, and self-validation theories.

Group cohesiveness and social loafing: Effects of a social interaction manipulation on individual motivation within groups.

Previous research has shown that individuals often engage in social loafing, exerting less effort on collective rather than individual tasks. However, nearly all of the prior research has examined noncohesive groups. An experiment was designed to test the hypothesis that social loafing can be reduced or eliminated among cohesive groups. Fifty-nine dyads discussed a controversial issue on which they agreed strongly (high cohesiveness), disagreed strongly (low cohesiveness), or disagreed mildly (control), then worked either coactively or collectively on an idea-generation task. Members of low-cohesiveness and control groups engaged in social loafing, whereas members of high-cohesiveness groups worked just as hard collectively as coactively. These findings are discussed in relation to S. J. Karau and K. D. Williams's (1993) Collective Effort Model of individual motivation in groups.

Perceived performance norm as a mediator in the effect of assigned goal on personal goal and task performance.

We conducted two experiments to test the hypothesis that assigned goals affect personal goals and task performance, in part, by providing normative information about the task. Normative information inferred from the goal was expected to influence performance expectancy and performance valence, which, in turn, would affect personal goal and, ultimately, performance. In Experiment 1, 60 undergraduate students were assigned performance goals of varying difficulty on a brainstorming task, and measures of perceived norm, performance expectancy, performance valence, personal goal, and task performance were obtained. Results of analyses of covariance and path analysis were generally consistent with the proposed cognitive mediation model. In Experiment 2, information about the performance norm was manipulated independently of goal difficulty for 135 undergraduates working on the same brainstorming task. Results of similar analyses revealed that (a) the effects of goal difficulty observed in Experiment 1 were attenuated by the presentation of normative information and (b) performance norm had significant effects on all of the dependent variables. The findings have implications for the integration of motivation theories and for the use of goal setting as a motivational technique.

Many hands make light the work: The causes and consequences of social loafing.

As reported in summary form by W. Moede (1927), an unpublished study found that in a rope-pulling task, while collective group performance increased somewhat with group size, it was less than the sum of the individual efforts (IE). IE decreased as group size increased. The present 2 experiments with 84 undergraduates investigated this effect using clapping and shouting tasks. Results replicate the earlier findings. The decrease in IE, which is here called social loafing, is in addition to losses due to faulty coordination of group efforts. The experimental generality, theoretical importance, widespread occurrence, and negative social consequences of social loafing are examined, along with ways of minimizing it.

Social connectedness, dysfunctional interpersonal behaviors, and psychological distress: Testing a mediator model.

The study examined the relationship among social connectedness, dysfunctional interpersonal behaviors, and psychological distress. The authors specifically hypothesized that the direct negative effect of social connectedness on psychological distress would be mediated by dysfunctional interpersonal behaviors. Prior to testing the hypothesis, the authors revised the original Social Connectedness Scale (SCS; R. A Lee and S. B. Robbins, 1995). Studies 1 and 2 describe the revision and validation of the SCS on separate samples of college students. In Study 3, the authors surveyed 194 college students and found support for the mediation hypothesis on general psychological distress. The importance of assessing social connectedness and tailoring counseling interventions for people with low connectedness and dysfunctional interpersonal behaviors is addressed.

Need for cognition, task difficulty, and the formation of performance expectancies.

In the present article, the authors analyze how performance expectancies are generated and how they affect actual performance. The authors predicted that task difficulty would affect performance expectancies only when cognitive motivation (i.e., need for cognition [NFC]) and cognitive capacity are high. This should be the case because analyzing task difficulty is a process requiring cognitive capacity as well as cognitive motivation. The findings supported the expected NFC × Difficulty interaction for the formation of performance expectancies (Study 1, Study 2), but only when cognitive capacity was high (Study 2). The authors also predicted that expectancies would affect actual performance only if the task is difficult and if task difficulty is taken into account when the expectancy is generated. This hypothesis was supported: Significant relations between performance expectancies and actual performance were found only for difficult tasks and for participants higher in NFC. Studies 5 and 6 showed clear evidence that the NFC × Difficulty interaction could not be explained by differences in the use of task-specific self-concepts. The findings were robust across academic, social, and physical tasks. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Influence of information, choice and task complexity upon goal acceptance, performance, and personal goals.

Tested the hypothesis that information about a goal and/or task, choice in setting a strategy to achieve a goal, and task complexity interact to influence goal acceptance, personal goals, and performance. A laboratory experiment with 96 college students working on a class-scheduling task was used to test the hypothesis. The task consisted of producing mock class schedules consisting of 5 nonredundant classes. The Ss were assigned to either high-information, choice manipulation, or task-complexity conditions. Ss were administered a questionnaire assessing goal acceptance, personal goals, and performance prior to and on completion of the task. Results of 3-way ANOVA conducted on measures of goal acceptance, personal goals, and performance supported the hypotheses that choice in goal-setting and the provision of information interact as do information and task complexity. A 2nd study conducted to generalize these findings also supported the hypotheses. In the 2nd study, 40 animal caregivers (average age 28 yrs) were participants in a replication of the laboratory experiment with task complexity as a repeated-measures factor. Findings are discussed as a means of expanding the position of participation within the goal-setting model. (15 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social loafing and group evaluation.

Recent work (e.g., S. Harkins; see PA, Vol 75:20027; K. Szymanski and Harkins; see PA, Vol 75:7410) has suggested that social loafing occurs because participants' outputs cannot be evaluated by the experimenter, by the coactors, or by the participants themselves. This analysis had focused on the output of the individual, but in loafing research, participants work together to produce a group product. However, in this prior work participants have been unable to make anything of this group product, because no standard of comparison has been made available. Several recent formulations (e.g., G. Goethals and J. Darley, 1987) have suggested that the potential for group evaluation could motivate performance. Testing this hypothesis in 2 experiments, 1 using an optimizing task and the other a maximizing task, we found that providing a standard that allowed the "group" to evaluate its performance eliminated the loafing effect. The implications of these findings for current theories of group evaluation are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Process and outcome evaluation of an on-line support group for Asian American male college students.

This study examined the process, outcome, and utilization patterns of an on-line support group (OSG) for Asian American male college students. Outcome measures indicated that the group participants felt supported, perceived the discussion topics as relevant, felt comfortable and connected to other group members, and preferred using aliases instead of their real identities. The discourse contained a high proportion of self-disclosure and provision of information, and more than half of the messages (58%) were responses to messages of other group members. These findings suggest that many of the components of group process theorized to be essential for effective groups can take place in OSGs. There were no significant posttest differences between the OSG (n?=?16) and control group (n?=?16) in ethnic identity or collective self-esteem. Implications of these findings for improving mental health and counseling services for culturally diverse populations are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

College students’ social justice interest and commitment: A social-cognitive perspective.

In this study, the authors examined the degree to which social-cognitive career theory (SCCT; R. W. Lent, S. D. Brown, & G. Hackett, 1994) explained the development of social justice interest and commitment. Data from 274 college students and latent variable path modeling were used to test theoretically and empirically derived SCCT direct and indirect effects structural models. The direct effects model estimated the direct effect of social supports and barriers on social justice commitment and the indirect effects model estimated the effect of social supports and barriers indirectly through self-efficacy. Overall, the present findings supported the use of SCCT within the social justice domain, as social justice self-efficacy and outcome expectations were useful in explaining the development of college students’ social justice interest and commitment. The present findings supported the indirect effects model of social justice interest and commitment over the direct effects model. Finally, unique to prior tests of SCCT in vocational and academic domains, social supports and barriers exhibited an indirect effect on commitment through outcome expectations. Study limitations, future directions for research, and implications for facilitating college students’ social justice interest and commitment are discussed.

Group identification as a moderator of the relationship between perceived social norms and alcohol consumption.

Previous research has shown that social norms are among the strongest predictors of college student drinking. Among college students, perceiving that others drink more heavily than themselves has been strongly and consistently associated with heavier drinking. Research has also shown that the more specifically others are defined, the stronger the association is with one's own drinking. In the current research, we evaluated whether group identification as defined by feeling closer to specific groups moderates the associations between perceived drinking norms in the group and one's own drinking. Participants included 3,752 (61% female) students who completed online assessments of their perceived drinking norms for 4 groups of students on their campus and identification with each group and participants' own drinking behavior. Results indicated that greater identification with same-sex students, same-race students, and same-Greek-status students was associated with stronger relationships between perceived drinking norms in the specific groups and own drinking.

Social Identity, Group Processes, and Performance in Synchronous Computer-Mediated Communication.

This study examined group processes in a synchronous context and their effects on performance, assuming that these processes would be strongly dependent on the salience of social identity. It was predicted that the mere categorization of students into an online group and comparison with other groups, 2 basic conditions related to social identity, would enhance group identification, interaction patterns, and group performance in a relatively complex academic task. As predicted, the categorization manipulation enhanced group identification and increased task- and morale-building communication. It was not related to performance. These findings invite a more thorough examination of the impact of social identity on the building of a sense of online community at the early stage of a learning process.

Self-efficacy theory: Implications for social facilitation and social loafing.

Two experiments indicate that the areas of social facilitation and social loafing are complementary and can be conceptualized in terms of self-efficacy theory. In Exp 1, efficacy expectancies were manipulated by false performance feedback, and outcome expectancies were manipulated by 3 group conditions (alone, coaction, and collective). In Exp 2, efficacy expectancies developed spontaneously while participants performed easy or difficult tasks, and outcome expectancies were manipulated by 3 evaluative conditions (alone, evaluation, and no evaluation). Consistent with social facilitation research, high efficacy evaluated participants performed better than alone participants, whereas low-efficacy evaluated participants performed worse than alone participants. Consistent with social loafing research, high efficacy nonevaluated participants performed worse than evaluated participants, whereas low-efficacy nonevaluated participants performed better than evaluated participants.

Change and consistency in social participation during early adulthood.

Reports a longitudinal study of the social interaction patterns of college students and adults. 113 adults (aged 26–31 yrs old) who had participated in similar studies in college kept detailed records of social activity for 2 wks. Three hypotheses were supported. First, from college to adulthood, opposite-sex socializing grew, whereas same-sex, mixed-sex, and group interactions decreased. Second, intimacy increased in adulthood, whereas satisfaction did not. Contrary to theories that focus on the formation of primary intimate relationships in early adulthood, intimacy increased in all interaction categories. Sex differences in the development of intimacy were also noted. Third, correlations revealed marked consistency over time in several variables. Implications of these findings for social development during early adulthood were examined. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attribution, affect, and college exam performance.

Results of a questionnaire study with 207 college students show that Ss attributed their own performance and the performance of the average student to ability, test difficulty, preparation, and luck. Consistent with the self-serving bias hypothesis, successful Ss perceived internal factors as more important causes and unsuccessful Ss perceived external factors as more important causes of their own performance than the performance of the average student. Furthermore, successful Ss saw internal and stable factors as more important causes of others' outcomes (as well as their own) than did unsuccessful Ss. Ss' anxiety about their performance and their ratings of the course and instructor were systematically, albeit weakly, linked with specific causal attributions. The implications of these causal inferences and affective responses in the educational context are discussed. (22 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of task importance and publicness on the relation between goal difficulty and performance.

In a laboratory study using undergraduate students (N?=?200), perceived task importance was found to moderate the relationship between goal level and performance. Moreover, participants performed better when both the goal and performance were public rather than anonymous. These findings suggest that by manipulating task importance and publicness of performance, it is possible to influence the impact that the difficulty of specific goals have on performance. The results are consistent with our hypotheses that the motivation to preserve one's self-image and the motivation to preserve one's public-image are two factors that determine effort and persistence devoted to assigned goals.
