It is predicted that the rapid acquisition of new genetic knowledge and related applications during the next decade will have significant implications for virtually all members of society. Currently, most people get exposed to information about genes and genetics only through stories publicized in the media. We sought to understand how individuals in the general population used and understood the concepts of “genetics” and “genes.” During in-depth one-on-one telephone interviews with adults in the United States, we asked questions exploring their basic understanding of these terms, as well as their belief as to the location of genes in the human body. A wide range of responses was received. Despite conversational familiarity with genetic terminology, many noted frustration or were hesitant when trying to answer these questions. In addition, some responses reflected a lack of understanding about basic genetic science that may have significant implications for broader public education measures in genetic literacy, genetic counseling, public health practices, and even routine health care. 相似文献

Recent research (Tormala & Petty, 2002) has demonstrated that when people resist persuasion, they can perceive this resistance and become more certain of their initial attitudes. This research explores the role of source credibility in determining when this effect occurs. In two experiments, participants received a counterattitudinal persuasive message. When participants counterargued this message, they became more certain of their attitudes, but only when it came from a source with high expertise. When the message came from a source with low expertise, resisting it had no impact on attitude certainty. This effect was shown using both a traditional measure of attitude certainty (Experiment 1) and a well‐established consequence of certainty—the correspondence between attitudes and behavioral intentions (Experiment 2). In addition, the effect was confined to high elaboration conditions, and occurred even when participants were not explicitly instructed to counterargue. These results are consistent with a metacognitive framework proposed to understand resistance to persuasion. 相似文献

Our behavior can change what we like and dislike. Although it seems clear that we might like something more when we smile (versus frown), or when we nod our heads (versus shake), it is important to understand the processes responsible for these changes in evaluation. It might be that agreement behaviors such as smiling and nodding work as cue, make us think about everything in a positive light, or it might be that they encourage us not to think much about the information we receive. This review describes the basic processes underlying embodied change, highlighting the role of a recently discovered meta‐cognitive process (called self‐validation) by which bodily responses can validate or invalidate (instead of changing) our thoughts. This new mechanism can account for some already established outcomes in embodied persuasion (e.g., more persuasion with smiling than frowning), but by a different process than postulated previously (smiling increases confidence in thoughts), as well as for some new findings (e.g., more persuasion for low than high powerful postures; more self‐confidence when performing doubtful postures). 相似文献

Researchers across many domains have examined the impact of externally presented numerical anchors on perceiver judgments. In the traditional paradigm, “anchored” judgments are typically explained as a result of elaborate thinking (i.e., confirmatory hypothesis testing that selectively activates anchor-consistent information in memory). Consistent with a long tradition in attitude change, we suggest that the same judgments can result from relatively thoughtful or non-thoughtful processes, with more thoughtful processes resulting in judgments that have more lasting impact. We review recent anchoring research consistent with this elaboration-based perspective and discuss implications for past anchoring results and theory in judgment and decision making. 相似文献

Attitude theory has long proposed a mechanism through which antecedents of message elaboration produce attitude strength consequences. However, little direct evidence exists for the intervening process. The proposed thoughtfulness heuristic holds that perceiving that more thought has taken place leads to greater attitude certainty. Two roles were established for this heuristic: first as a mediator of the impact of antecedents of elaboration on attitude certainty and second as a way to influence attitude certainty independent of actual elaboration. In Studies 1 and 2, antecedents of elaboration (need for cognition, distraction) impacted attitude certainty because they impacted the actual amount of processing, which in turn affected perceptions of the amount of processing. In Studies 3 and 4, a manipulation of perceived thought impacted certainty independent of actual thought (i.e., after thinking had already occurred). Furthermore, the thoughtfulness heuristic was shown to influence behavioral intentions, establishing perceived amount of processing as both a mediator and an independent cause of attitude strength consequences. 相似文献

The authors investigated the predictive utility of people's subjective assessments of whether their evaluations are affect- or cognition driven (i.e., meta-cognitive bases) as separate from whether people's attitudes are actually affect- or cognition based (i.e., structural bases). Study 1 demonstrated that meta-bases uniquely predict interest in affective versus cognitive information above and beyond structural bases and other related variables (i.e., need for cognition and need for affect). In Study 2, meta-bases were shown to account for unique variance in attitude change as a function of appeal type. Finally, Study 3 showed that as people became more deliberative in their judgments, meta-bases increased in predictive utility, and structural bases decreased in predictive utility. These findings support the existence of meta-bases of attitudes and demonstrate that meta-bases are distinguishable from structural bases in their predictive utility. 相似文献

A questionnaire was administered to 142 mate students who were enrolled in ROTC and 18 male students who had dropped out of ROTC. Several months later seven of the above 142 subjects dropped out of ROTC. A ratio expectancy theory model was developed from the questionnaire as an operational definition of motivation to remain in ROTC. The results indicated that the 25 dropouts had a significantly lower (p < .001) score on this motivational measure than the 135 subjects who were still enrolled in ROTC, and also that these latter subjects were as strongly attracted to a civilian job as they were to an Army job. The implications of these findings relative to the ability of the Army to attract career officers were discussed. 相似文献
