Social loafing and social compensation: the effects of expectations of co-worker performance

Previous research has suggested that people tend to engage in social loafing when working collectively. The present research tested the social compensation hypothesis, which states that people will work harder collectively than individually when they expect their co-workers to perform poorly on a meaningful task. In 3 experiments, participants worked either collectively or coactively on an idea generation task. Expectations of co-worker performance were either inferred from participants' interpersonal trust scores (Experiment 1) or were directly manipulated by a confederate coworker's statement of either his intended effort (Experiment 2) or his ability at the task (Experiment 3). All 3 studies supported the social compensation hypothesis. Additionally, Experiment 3 supported the hypothesis that participants would not socially compensate for a poorly performing co-worker when working on a task that was low in meaningfulness.     

From sucker to saint: moralization in response to self-threat

ABSTRACT— When people's rationality and agency are implicitly called into question by the more expedient behavior of others, they sometimes respond by feeling morally superior; this is referred to as the sucker-to-saint effect. In Experiment 1, participants who completed a tedious task and then saw a confederate quit the same task elevated their own morality over that of the confederate, whereas participants who simply completed the task or simply saw the confederate quit did not. In Experiment 2, this effect was eliminated by having participants contemplate a valued personal quality before encountering the rebellious confederate, a result suggesting a role for self-threat in producing moralization. These studies demonstrate that moral judgments can be more deeply embedded in judges' immediate social contexts—and driven more by motivations to maintain self-image—than is typically appreciated in contemporary moral-psychology research. Rather than uphold abstract principles of justice, moral judgment may sometimes just help people feel a little less foolish.     

Your heart makes my heart move: Cues of social connectedness cause shared emotions and physiological states among strangers

Two experiments tested the hypothesis that cues of social connectedness could lead even new interaction partners to experience shared emotional and physiological states. In Experiment 1, a confederate prepared for a stress-inducing task. Participants who had been led to feel socially connected to the confederate reported feeling greater stress than participants who had not. In Experiment 2, a confederate ran vigorously in place. Socially-connected participants had greater cardiovascular reactivity (heart rate and blood pressure) than controls. Each study held constant exposure to the confederate. The results suggest that the sharing of psychological and physiological states does not occur only between long-standing relationship partners, but can also result from even subtle experiences of social connectedness. These findings illustrate the dynamic and fluid ways in which important aspects of self can change in response to cues of social relatedness.     

Ageing stereotypes influence the transmission of false memories in the social contagion paradigm

ABSTRACT

These experiments are the first to investigate the impact of confederate accuracy, age, and age stereotypes in the social contagion of memory paradigm. Across two experiments, younger participants recalled household scenes with an actual (Experiment 1) or virtual (Experiment 2), older or younger confederate who suggested different proportions (0%, 33% or 100%) of false items during collaboration. In Experiment 2, positive and negative age stereotypes were primed by providing bogus background information about our older confederate before collaboration. Across both experiments, if confederates suggested false items participants readily incorporated these into their own memory reports. In Experiment 1, when no age stereotype was primed, participants adopted similar proportions of false items from younger and older confederates. Importantly, in Experiment 2, when our older confederate was presented in terms of negative ageing stereotypes, participants reported less false items and were better able to correctly identify the source of those false items.     

Contagion and Differentiation in Unethical Behavior: The Effect of One Bad Apple on the Barrel

ABSTRACT— In a world where encounters with dishonesty are frequent, it is important to know if exposure to other people's unethical behavior can increase or decrease an individual's dishonesty. In Experiment 1 , our confederate cheated ostentatiously by finishing a task impossibly quickly and leaving the room with the maximum reward. In line with social-norms theory, participants' level of unethical behavior increased when the confederate was an in-group member, but decreased when the confederate was an out-group member. In Experiment 2 , our confederate instead asked a question about cheating, which merely strengthened the saliency of this possibility. This manipulation decreased the level of unethical behavior among the other group members. These results suggest that individuals' unethicality does not depend on the simple calculations of cost-benefit analysis, but rather depends on the social norms implied by the dishonesty of others and also on the saliency of dishonesty.     

The Effects of Social Influence on Perceptual and Affective Reactions to Scenes of Sexual Violence1

In 2 experiments, we examined the effect of social influence (discussion and modeling) on men's and women's perceptual and affective reactions to a sexually violent film scene depicting gang rape. In Experiment 1, women who discussed the film rated the perpetrators as more responsible compared to participants in all other conditions. Men who did not discuss the film reported higher levels of positive affect compared to participants in all other conditions. In Experiment 2, men and women were affected by the social influence manipulation similarly. As predicted, participants differed in their attributions of responsibility depending on a confederate's response to the film scene. Participants who heard a confederate say that the men in the film were responsible for the rape rated these men as relatively more responsible than did participants in a neutral confederate condition or in a condition in which the confederate said that the woman in the film was responsible for the rape.     

Self-regulation of priming effects on behavior

In three experiments, we tested whether people can protect their ongoing goal pursuits from antagonistic priming effects by using if-then plans (i.e., implementation intentions). In Experiment 1, concept priming did not influence lexical decision time for a critical stimulus when participants had formed if-then plans to make fast responses to that stimulus. In Experiment 2, participants who were primed with a prosocial goal allowed a confederate who asked for help to interrupt their work on a focal task for a longer time if they had merely formed goal intentions to perform well than if they had also formed implementation intentions for concentrating on the task. In Experiment 3, priming the goal of being fast increased driving speed and errors for participants who had formed mere goal intentions to drive only as fast as safety allowed or who had formed no goal intentions, whereas the driving of participants who had formed such goal intentions as well as implementation intentions showed no such priming effects. Our findings indicate that implementation intentions are an effective self-regulatory tool for shielding actions from disruptive concept- or goal-priming effects.     

Don't it make my brown eyes blue: Co-witness misinformation about a target's appearance can impair target-absent line-up performance

Misinformation from another witness has been shown to impair eyewitness reports, but little is known about how it may influence eyewitness identification. In Experiment 1, adult pairs comprising one participant and one experimental confederate viewed a video clip of a staged theft. Half of the participants were then misinformed by the confederate that the thief's accomplice had blue eyes (in fact, they were brown). Next, individual participants described the accomplice and completed a target-absent photographic line-up task comprising blue-eyed members. Misinformed participants were several times more likely than controls to describe the accomplice as having blue eyes, and twice as likely to identify someone from the line-up. In Experiment 2, when line-up members’ eye colour was digitally altered from blue to brown, the line-up effect disappeared, suggesting that the increase in identifications in Experiment 1 was not a generalised increase in willingness to choose from the line-up. In Experiment 3, we discounted the possibility that discussion alone could account for the line-up misinformation effect, by subjecting all participants to co-witness discussion.     

I still think it was a banana: memorable 'lies' and forgettable 'truths'

Interpersonal influences on cognition can distort memory judgements. Two experiments examined the nature of these 'social' influences, and whether their persistence is independent of their accuracy. Experiment 1 found that a confederate's social proximity, as well as the content and the confidence of their utterances, interactively modulates participants' immediate conformity. Notably, errant confederate statements that 'lied' about encoded material had a particularly strong immediate distorting influence on memory judgements. Experiment 2 revealed that these 'lies' were also memorable, continuing a day later to impair memory accuracy, while accurate confederate statements failed to produce a corresponding and lasting beneficial effect on memory. These findings suggest that an individual's 'informational' social influence can be selectively heightened when they express misinformation to someone who suspects no deceptive intent. The methods newly introduced here thus allow multiple social and cognitive factors impinging on memory accuracy to be manipulated and examined during realistic, precisely controlled dyadic social interactions.     

Embodied Information in Cognitive Tasks: Haptic Weight Sensations Affect Task Performance and Processing Style

Research in the field of embodied cognition showed that incidental weight sensations influence peoples’ judgments about a variety of issues and objects. Most studies found that heaviness compared to lightness increases the perception of importance, seriousness, and potency. In two experiments, we broadened this scope by investigating the impact of weight sensations on cognitive performance. In Experiment 1, we found that the performance in an anagram task was reduced when participants held a heavy versus a light clipboard in their hands. Reduced performance was accompanied by an increase in the perceived effort. In Experiment 2, a heavy clipboard elicited a specific response heuristic in a two-alternative forced-choice task. Participants showed a significant right side bias when holding a heavy clipboard in their hands. After the task, participants in the heavy clipboard condition reported to be more frustrated than participants in the light clipboard condition. In both experiments, we did not find evidence for mediated effects that had been proposed by previous literature. Overall, the results indicate that weight effects go beyond judgment formation and highlight new avenues for future research.     

Likable co-witnesses increase eyewitness accuracy and decrease suggestibility

This study examines the impact of likability on memory accuracy and memory conformity between two previously unacquainted individuals. After viewing a crime, eyewitnesses often talk to one another and may find each other likable or dislikable. One hundred twenty-seven undergraduate students arrived at the laboratory with an unknown confederate and were assigned to a likability condition (i.e., control, likable or dislikable). Together, the pair viewed pictures and was then tested on their memory for those pictures in such a way that the participant knew the confederate's response. Thus, the participant's response could be influenced both by his or her own memory and by the answers of the confederate. Participants in the likable condition were more accurate and less influenced by the confederate, compared with the other conditions. Results are discussed in relation to research that shows people are more influenced by friends than strangers and in relation to establishing positive rapport in forensic interviewing.     

Close interpersonal proximity modulates visuomotor processing of object affordances in shared,social space

Research suggests that the human brain codes manipulable objects as possibilities for action, or affordances, particularly objects close to the body. Near-body space is not only a zone for body-environment interaction but also is socially relevant, as we are driven to preserve our near-body, personal space from others. The current, novel study investigated how close proximity of a stranger modulates visuomotor processing of object affordances in shared, social space. Participants performed a behavioural object recognition task both alone and with a human confederate. All object images were in participants’ reachable space but appeared relatively closer to the participant or the confederate. Results revealed when participants were alone, objects in both locations produced an affordance congruency effect but when the confederate was present, only objects nearer the participant elicited the effect. Findings suggest space is divided between strangers to preserve independent near-body space boundaries, and in turn this process influences motor coding for stimuli within that social space. To demonstrate that this visuomotor modulation represents a social phenomenon, rather than a general, attentional effect, two subsequent experiments employed nonhuman joint conditions. Neither a small, Japanese, waving cat statue (Experiment 2) nor a metronome (Experiment 3) modulated the affordance effect as in Experiment 1. These findings suggest a truly social explanation of the key interaction from Experiment 1. This study represents an important step toward understanding object affordance processing in real-world, social contexts and has implications broadly across fields of social action and cognition, and body space representation.     

Effects of role model deservingness on overcoming performance deficits induced by stereotype threat

Previous research has shown that exposure to successful role models can restore performance that had been impaired by stereotype threat, and that some role models are more effective than others. The present research examined the effects of role model deservingness on women's mathematics test performance after being placed under stereotype threat. In Experiment 1, a woman who attained success by herself (deserved) proved a more effective role model than an equally likable and successful woman whose success was handed to her (not deserved). In Experiment 2, women role models proved more effective at combating stereotype threat when their successes were attributable to internal‐stable (deserved) than external‐unstable (not deserved) causes, an effect that was partially mediated by reduction in extra‐task thinking. The results are seen as having implications for theories of stereotype threat and causal attribution. Copyright © 2010 John Wiley & Sons, Ltd.     

The influences of partner accuracy and partner memory ability on social false memories

In this study, we examined whether increasing the proportion of false information suggested by a confederate would influence the magnitude of socially introduced false memories in the social contagion paradigm Roediger, Meade, & Bergman (Psychonomic Bulletin & Review 8:365–371, 2001). One participant and one confederate collaboratively recalled items from previously studied household scenes. During collaboration, the confederate interjected 0 %, 33 %, 66 %, or 100 % false items. On subsequent individual-recall tests across three experiments, participants were just as likely to incorporate misleading suggestions from a partner who was mostly accurate (33 % incorrect) as they were from a partner who was not at all accurate (100 % incorrect). Even when participants witnessed firsthand that their partner had a very poor memory on a related memory task, they were still as likely to incorporate the confederate’s entirely misleading suggestions on subsequent recall and recognition tests (Exp. 2). Only when participants witnessed firsthand that their partner had a very poor memory on a practice test of the experimental task itself were they able to reduce false memory, and this reduction occurred selectively on a subsequent individual recognition test (Exp. 3). These data demonstrate that participants do not always consider their partners’ memory ability when working on collaborative memory tasks.     

Social influence on metacognitive evaluations: The power of nonverbal cues

Metacognitive evaluations refer to the processes by which people assess their own cognitive operations with respect to their current goal. Little is known about whether this process is susceptible to social influence. Here we investigate whether nonverbal social signals spontaneously influence metacognitive evaluations. Participants performed a two-alternative forced-choice task, which was followed by a face randomly gazing towards or away from the response chosen by the participant. Participants then provided a metacognitive evaluation of their response by rating their confidence in their answer. In Experiment 1, the participants were told that the gaze direction was irrelevant to the task purpose and were advised to ignore it. The results revealed an effect of implicit social information on confidence ratings even though the gaze direction was random and therefore unreliable for task purposes. In addition, nonsocial cues (car) did not elicit this effect. In Experiment 2, the participants were led to believe that cue direction (face or car) reflected a previous participant's response to the same question—that is, the social information provided by the cue was made explicit, yet still objectively unreliable for the task. The results showed a similar social influence on confidence ratings, observed with both cues (car and face) but with an increased magnitude relative to Experiment 1. We additionally showed in Experiment 2 that social information impaired metacognitive accuracy. Together our results strongly suggest an involuntary susceptibility of metacognitive evaluations to nonverbal social information, even when it is implicit (Experiment 1) and unreliable (Experiments 1 and 2).     

Pragmatic use of stereotyping in teamwork: social loafing and compensation as a function of inferred partner-situation fit

Using 4 experiments, the authors examined how stereotypic information about teammates influences social loafing and compensation during collective tasks. In each experiment, participants performed better on cognitive tasks when there was a poor (vs. good) fit between the stereotypic strengths of their partner and the requirements of the task. This pattern occurred whether participants used gender stereotypes (Experiment 1) or occupational stereotypes (Experiments 2 to 4) and occurred even when participants only anticipated working on a collective task (Experiment 4). In Experiment 3, the pattern occurred only in the collective (not in the coactive) condition, providing direct evidence for social loafing. Together, these results suggest that people use stereotypes to tune their motivation to optimize the ratio of their own individual effort to the team's expected output.     

As easy to memorize as they are to classify: The 5–4 categories and the category advantage

Recently, it has been suggested that some categories commonly used in category learning research are eliciting primarily item-level memorization strategies. A new measure of generalization, the category advantage, was introduced and used to test performance on the popular "5-4" categories. To estimate a category advantage, performance on a standard category learning task is compared with performance in an identification task, where participants learn a unique response to each stimulus. Once corrected for differences in chance expectancy, the advantage shown for the category learning task represents the degree to which participants capitalize on the natural similarity structure of the categories. In Experiment 1, the category advantage measure was validated on structured and unstructured categories. In Experiments 2 and 3, the 5-4 categories failed to produce a category advantage when tested with either of two stimulus types, suggesting that these categories elicit predominantly memorization.     

MODELING INFLUENCES ON ALCOHOLICS' RATES OF ALCOHOL CONSUMPTION

Two experiments were designed to examine modeling influences on alcoholics' alcohol consumption. Three male alcoholics were paired with confederates, posing as alcoholics. In Experiment 1, alcoholic-confederate pairs participated in a 1-hour taste-rating task, which involved rating different wines on a list of adjectives. Experiment 2 consisted of 1-hour ad lib access to wine in a naturalistic bar setting. In both experiments, confederates alternated 15-minute periods of heavy and light consumption, drinking fluids resembling wine. The amount of wine consumed by alcoholics in each period was secretly recorded and the data examined on a single subject basis. In Experiment 1, two subjects increased and decreased consumption along with their confederate. The third subject followed the confederate's pattern only after the confederate demonstrated heavy consumption. All three subjects varied consumption with the confederate during Experiment 2, performed later on the same day. These results suggest that alcoholics' alcohol consumption can be modified by the social influences of modeling. The implications of this finding for the loss of control hypothesis and alcoholism treatment maintenance were discussed.     

Self-determination and the consequences of social comparison

The present research examined the consequences of social comparison as a function of individual differences in self-determination. Competing hypotheses were made regarding whether the effects of social comparison would be determined more by the tendency toward pressure and ego-defensiveness (higher controlled orientation), by the absence of choice and unconditional positive self-regard (lower autonomy orientation), or both. A forced comparison was created in which 79 college students completed a word finding task and received feedback about their performance along with that of a better or worse performing confederate. Autonomy orientation moderated comparison consequences such that less autonomous individuals experienced increased negative changes in affect and decreased self-esteem when paired with a better performing other. This was especially true, for affect, when participants had been told that the task was related to intelligence. Results provide preliminary support for integration of self-determination and social comparison theories.
