Moderation of classic social psychological effects by demographics in the U.S. adult population: New opportunities for theoretical advancement.

For decades, social psychologists have collected data primarily from college undergraduates and, recently, from haphazard samples of adults. Yet researchers have routinely presumed that thus observed treatment effects characterize "people" in general. Tests of seven highly cited social psychological phenomena (two involving opinion change resulting from social influence and five involving the use of heuristics in social judgments) using data collected from randomly sampled, representative groups of American adults documented generalizability of the six phenomena that have been replicated previously with undergraduate samples. The 1 phenomenon (a cross-over interaction revealing an ease of retrieval effect) that has not been replicated successfully previously in undergraduate samples was also not observed here. However, the observed effect sizes for the replicated phenomena were notably smaller on average than the meta-analytic effect sizes documented by past studies of college students. Furthermore, the phenomena were strongest among participants with the demographic characteristics of the college students who typically provided data for past published studies, even after correcting for publication bias in past studies using a new method, called the behaviorally-informed file-drawer adjustment. The six successful replications suggest that phenomena identified in traditional laboratory research also appear as expected in representative samples but more weakly, so observed effect sizes should be generalized with caution. The evidence of demographic moderators suggests interesting opportunities for future research to better understand the mechanisms of the effects and their limiting conditions.

Social power and attitude strength over the life course.

Past findings indicate that middle-aged adults in the United States tend to be more resistant to attitude change than younger and older adults, but little is known about why this is so. The authors propose that midlife adults' disproportionate occupation of high-power social roles (which call for resoluteness) may partly explain their heightened resistance to persuasion. Using nationally representative data sets, the article first documents that in various domains the possession of social power peaks in midlife. It next documents that middle-aged adults place a high value on resoluteness, which suggests that they have internalized powerful role norms. Next, it shows that directly activating the concept of social power increases the perceived value of resoluteness. Finally, it demonstrates that the possession of powerful social roles partially mediates the relationship between age and resistance to persuasion. This work is the first to uncover a mechanism responsible for changes in attitude strength over the adult life course.

Openness to attitude change as a function of temporal perspective.

Three studies investigated the impact of temporal perspective on people's dominant social goals and explored the implications of these goals for openness to attitude change. Participants who perceived time as limited expressed social preferences in accordance with emotion-regulation goals (Study 1), were more prone to modify their attitude to bring it into line with the attitude of an anticipated social partner (Study 2), and were more likely to go along with peer consensus opinion on a campus issue (Study 3) than were participants who perceived time as expansive. These studies demonstrate that perception of time plays a vital role in motivating social goals within the persuasion context.

How surveillance begets perceptions of dishonesty: the case of the counterfactual sinner.

Three studies support the hypothesis that observers' impressions of actors reflect not only what actors do but also what they can easily be imagined doing. Participants in Studies 1 and 2 observed a 10-year-old boy take a math test in a context in which the incentive to cheat and the constraints against cheating varied. When the incentive to cheat was high but the likelihood of getting caught was also high, observers perceived a target who resisted the temptation to cheat as less honest than the average boy. This effect was not found when the incentive to cheat was low, which suggests that its occurrence under high temptation resulted from observers in that condition generating the counterfactual thought that the target would have cheated had the likelihood of detection been low. Study 3 further supported the link between spontaneous counterfactual thought and inferences of dishonesty. The implications of the counterfactual correspondence bias are discussed.

Attitude importance and the accumulation of attitude-relevant knowledge in memory.

People who attach personal importance to an attitude are especially knowledgeable about the attitude object. This article tests an explanation for this relation: that importance causes the accumulation of knowledge by inspiring selective exposure to and selective elaboration of relevant information. Nine studies showed that (a) after watching televised debates between presidential candidates, viewers were better able to remember the statements made on policy issues on which they had more personally important attitudes; (b) importance motivated selective exposure and selective elaboration: Greater personal importance was associated with better memory for relevant information encountered under controlled laboratory conditions, and manipulations eliminating opportunities for selective exposure and selective elaboration eliminated the importance-memory accuracy relation; and (c) people do not use perceptions of their knowledge volume to infer how important an attitude is to them, but importance does cause knowledge accumulation.

Attitudes in the social context: the impact of social network composition on individual-level attitude strength.

Four studies, using both experimental and correlational designs, explored the implications of being embedded within attitudinally congruent versus attitudinally heterogeneous social networks for individual-level attitude strength. Individuals embedded within congruent social networks (i.e., made up of others with similar views) were more resistant to attitude change than were individuals embedded within heterogeneous social networks (i.e., made up of others with a range of views). Mediational evidence suggests that attitudinally congruous social networks may increase attitude strength by decreasing attitudinal ambivalence and perhaps by increasing the certainty with which people hold their attitudes. These results suggest that features of the social context in which an attitude is held have important implications for individual-level attitude strength.
