The Effects of Source Credibility and Performance Rating Discrepancy on Reactions to Multiple Raters1

Using multiple feedback sources, the present study investigated the effects of source credibility and performance rating discrepancy on recipients' reactions. Individuals performed an ambiguous group task, rated their own performance on the task, and were later provided bogus feedback ostensibly from their peers and an expert rater. Individuals reacted toward the feedback and the source of the feedback as a function of the rating discrepancy and credibility of the feedback source. Generally, more credible sources and their feedback were evaluated more favorably. However, as predicted, this effect was overcome by performance rating discrepancy in the predicted conditions. The results show the importance of studying the interactive effects of message and source characteristics on individuals' reactions.     

Prime, Frame, and Source Factors: Semantic Valence in Message Judgment

Healthcare communication is an area that offers great benefits in the promotion of preventive health behavior. Given that physical activity can significantly reduce risk factors that are associated with major chronic diseases, it is paramount to examine the promotion of physical activity through appropriate message designs. This study employs priming theory, the framing postulate of prospect theory, and the source factor to examine effective message design in the promotion of exercise. Overall, it shows that semantic consistencies between prime and frame, as well as frame and source, are more conducive to message persuasion. Hence, the contention of framing by the type of health behavior ( Rothman & Salovey, 1997 ) is moderated by prime and source factors.     

Message Valence,Familiarity, Sex,and Personality Effects on the Perceptual Distortion of Height

The perceptual distortion of height was examined in a group of American male and female college student volunteers (n = 139). A message which announced either good or bad news was delivered by a familiar or unfamiliar person who was either male or female. After hearing the message, the students were asked to estimate the height of the communicator. Additionally, the variables of self-esteem and independence of judgment were measured. Results indicated that familiarity with the message source (p <.0025) as well as sex of the communicator (p <.024) were predictors of the perceptual distortion of height, but message valence was not. Neither self-esteem nor independence of judgment was functionally related to the proclivity to distort the heights of the communicators.     

The Effects of Source Credibility and Message Framing on Exercise Intentions,Behaviors, and Attitudes: An Integration of the Elaboration Likelihood Model and Prospect Theory1

This study examined the influence of source credibility and message framing on promoting physical exercise in university students. Participants were randomly assigned to reading a positively or negatively framed communication that was attributed to either a credible or a noncredible source. Exercise intentions and attitudes were measured immediately following the delivery of the communication and following a 2‐week delay. Exercise behavior was also measured following the delay. There were Source Frame interactions for the exercise intentions, exercise behaviors, and cognitive response/elaboration measures such that participants receiving a positively framed communication from a credible source elaborated more and reported more positive exercise intentions and behaviors than participants in the other conditions. The results of the present investigation indicate that it might be beneficial for health professionals to provide exercise‐related information stressing the benefits of participating in exercise, rather than the traditional fear appeals, to motivate clients to engage in regular physical exercise. Implications for future research are discussed.     

Prepurchase Attribute Verifiability,Source Credibility,and Persuasion

Recent research has found that search and experience attribute claims are processed differently by consumers, with search attribute claims typically being more believable than experience attribute claims. It is, however, routinely the case that marketers desire to promote a product by making a claim featuring an experience attribute. The marketing literature has largely neglected the issue of how to enhance persuasion of experience attribute claims. The purpose of this research was to fill this void. We reason that source credibility impacts the receipt of experience claims and search claims differently. We then report results of 2 experiments featuring 2 different types of sources in the context of 2 different categories that suggest a source high in credibility can be employed to make experience claims more persuasive. The contributions our study makes to the persuasion literature and avenues for future research are discussed.     

The Effects of Feedback Source and Plausibility of Hindsight Bias

Whenever people try to recollect an earlier given estimate after they have received feedback about the true solution, they tend to overestimate what they had known in foresight. This phenomenon is known as “hindsight bias”. This paper reports three attempts to eliminate hindsight bias by labelling the feedback value as another person's estimate (instead of as the solution) and by providing extremely incorrect (instead of the true) values as feedback. Both variations, however alone and in combination failed to reduce hindsight bias. Only when the data were separated according to whether participants considered the feedback value plausible or not did cases of unbiased recollections emerge: Feedback values that were labelled as estimates of another person and found to be implausible did not lead to hindsight bias. This finding argues against the view that hindsight bias is an automatic and unavoidable effect of feedback presentation.     

Rumors Denials as Persuasive Messages: Effects of Personal Relevance,Source, and Message Characteristics1

Denial is a commonly used strategy to rebut a false rumor. However, there is a dearth of empirical research on the effectiveness of denials in combating rumors. Treating denials as persuasive messages, we conducted 3 laboratory‐based simulation studies testing the overall effectiveness of denials in reducing belief and anxiety associated with an e‐mail virus rumor. Under the framework of the elaboration likelihood model, we also tested the effects of denial message quality and source credibility, and the moderating effects of personal relevance. Overall, the results provided some support for the effectiveness of denials with strong arguments and an anxiety‐alleviating tone in reducing rumor‐related belief and anxiety. The effects of denial wording and source credibility were visible for participants who perceived high personal relevance of the topic. Limitations of the current research and future research directions are discussed.     

Effects of Goal Choice,Strategy Choice,and Feedback Source on Goal Acceptance,Performance and Subsequent Goals1

This study examined the effects of goal choice, strategy choice, and feedback source on goal acceptance, performance, and future self-set goals. The results were partially consistent with earlier work by Earley and Kanfer (1985) in that goal and strategy choice interacted to affect initial performance and goal acceptance. However, the nature of the performance interaction was not as expected. Results pertaining to future goals and subsequent performance suggested that goal choice was an important determinant of future goals and that feedback, goal choice, and strategy choice interacted to influence subsequent performance. Contrary to expectations, feedback source did not exert a main effect on subsequent performance, goal setting, or perceptions of feedback acceptance and usefulness. Discussion centered on the differential impact of choice on perceptual and behavioral variables and the failure of self-feedback to significantly affect subsequent goals and performance.     

Feedback,Adult Intervention,and Peer Collaboration in Initial Logo Learning

We assigned 144 children (mean age = 6 years, 11 months) at random to one of four conditions: (a) child alone, (b) child-plus-peer, (c) child-plus-adult (the child's teacher), or (d) child-plus-peer-plus-adult. The task was to control a Turtle using simple Logo commands, and a feedback model of task performance was used to generate pretest and posttest measures. Children working with an adult (Conditions C and D) performed significantly better than children working without an adult (Conditions A and B); however, there were no significant effects due to condition either on subsequent individual performance or on pretest to posttest gains. Analysis of interaction in the child-plus-adult condition showed that the adults' interventions did not consistently result in either the prevention of error or its productive use in debugging. It is concluded that feedback and collaboration may not be additive in their effects on learning.     

When Self Is the Source: Effects of Media Customization on Message Processing

Customization of media technologies enables users to become active sources in the communication process. But, does this sense of “self-as-source” alter the way users process information received via customized interfaces? A between-subjects experiment (N = 146) was conducted to answer this question. Data indicate that the effect of self-driven customization (high vs. low self-as-source) on persuasive message processing is mediated by perceived identity. Those who experience high self-as-source tend to process messages less systematically, but perceive the message topic as more important and show greater intention to follow the suggestions of messages than those with a low sense of self-as-source, an effect that is mediated by perceived identity. Theoretical implications for persuasive technologies, dual process models, and the agency model of customization are discussed, followed by practical implications for communicators who wish to incorporate new media technologies into their social influence campaigns.     

Compensatory Effects of Cognitive Characteristics of the Source,the Message,and the Receiver Upon Attitude Change

This study explored the interactive effects of four cognitive variables (perceived expertise of the source, recipients' initial attitudes, number of arguments, and message sidedness) on attitude change. A 2 × 2 × 2 factorial design was used (N = 236 Canadian students): Results showed a positive and significant main effect of initial attitude on attitude change and three significant compensatory effects of independent variables on attitude change: (a) two-sided messages were more persuasive with fewer arguments; conversely for one-sided messages; (b) high expertise compensated for low number of arguments and conversely; and (c) higher expertise was more persuasive in the case of unfavorable recipients and conversely. Results also showed that when the message was one-sided and the number of arguments was large, low expertise was more persuasive than high expertise on initially opposed recipients, which confirms the cognitive response.     

Framing Charity Advertising: Influences of Message Framing,Image Valence,and Temporal Framing on a Charitable Appeal1

This study examined when and how charitable advertisements could be effective in the context of child poverty. An experiment investigated the influences of message framing, image valence, and temporal framing on a charitable appeal. The results indicate that image valence enhances framing effects on advertising effectiveness of a charitable appeal when the image is congruent with the framed message, especially when the image and the message are presented negatively. A short‐term temporal frame facilitates effects of a negatively framed message with a negative pictorial presentation. Alternatively, a long‐term temporal frame increases advertising influences of a positively framed message with a positive pictorial image. Relevance for information processing of charity advertising is discussed.     

Source Credibility and Attitude Certainty: A Metacognitive Analysis of Resistance to Persuasion

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.     

Culturally Sensitive AIDS Educational Videos for African American Audiences: Effects of Source, Message, Receiver, and Context

The importance of using culturally sensitive educational materials in HIV-related interventions with racial and ethnic minority groups is widely recognized. However, little empirical research has been conducted to assess the relative effectiveness of different techniques for creating culturally sensitive AIDS educational videos. Two field experiments with three samples of African American adults (N = 174, 173, and 143) were conducted to assess how source characteristics (race of communicator), message characteristics (multicultural message vs. culturally specific message), and audience characteristics (racial distrust and AIDS-related distrust) influence proximate (perceptions of the message's credibility and attractiveness) and distal (AIDS-related attitudes, beliefs, and behavioral intentions) output variables for AIDS educational videos. In Study 1, an AIDS video with a culturally specific message was rated as more credible, more attractive, and of higher quality than was a video with a multicultural message. The multicultural message was rated less favorably when delivered by a White announcer than when the announcer was Black. In Study 2, the same pattern was replicated with a second community sample and a campus-based sample. Study 2 also indicated that a multicultural message might be more effective if delivered in a culturally specific context, namely, after audience members watch a culturally specific video. Minimal changes were observed in distal outcome variables. It is argued that influencing proximate output variables is necessary, though not sufficient, for effecting long-term change in AIDS-related attitudes, beliefs, and behaviors.     

来源记忆中背景的情绪效价与唤醒对提取过程的影响

以往研究表明情绪背景对来源记忆存在影响,但背景的情绪效价和唤醒如何影响熟悉性及回想尚存争议。本研究以ERPs技术作为测量手段,采用来源记忆多键范式,操纵背景的情绪效价及唤醒强度,以探讨编码阶段背景情绪影响来源记忆提取的认知神经机制。学习阶段,呈现中性汉字及情绪图片（正性高唤醒、正性低唤醒、负性高唤醒、负性低唤醒）;测验阶段,仅呈现汉字,被试进行五键判断。行为结果发现：来源正确的比率比来源错误的比率更高,反应时更短;同时提取正性背景的辨别力更强,反应时更短;提取高唤醒背景反应时更短。脑电结果发现了分别代表熟悉性及回想的FN400及LPC新旧效应,且在500～700 ms,提取正性背景及高唤醒背景诱发显著更正的ERPs,但效价与唤醒没有交互作用。总体来说,来源记忆中背景效价及唤醒度对回想过程存在独立影响,体现为正性背景及高唤醒背景对来源提取的促进作用。     

Effects of Video Modeling and Feedback on Mothers' Implementation of Peer‐to‐Peer Manding

Children with autism spectrum disorder (ASD) exhibit deficits in appropriate requesting such as manding to peers. Experiment 1 used feedback and modeling to train three mothers to increase manding between three children with ASD and their typical siblings or peers. Video modeling and feedback increased the mother's correct implementation of the treatment but a causal relation was not established over the children's manding. Experiment 2 aimed to address the lack of functional control observed in the children's data using a partial component analysis. For one of the children there was a functional relation between the materials' location, which appeared to act as a motivating operation. When Sam's mother positioned the materials correctly his manding increased. These data indicated that a simple training protocol could be used to train caregivers to implement a complex social skill such as peer‐to‐peer interaction.

The Effects of Trait Driving Anger, Anonymity, and Aggressive Stimuli on Aggressive Driving Behavior

We examined the effects of trait driving anger, aggressive stimuli, and anonymity on aggressive driving behavior in a driving simulation task. High and low driving anger participants were randomly assigned to one of four conditions: (a) anonymous vs. identifiable driver; and (b) exposure to aggressive stimuli versus nonaggressive stimuli. Participants drove more aggressively when they were anonymous (d = .28) and exposed to aggressive stimuli (d = .05). Males drove more aggressively than did females (d = .06). No main or interaction effects were found for trait driving anger. Results suggest that situational factors affecting other forms of aggression are also important in aggressive driving.     

Individual Differences in Mediators and Reactions to a Personal Safety Threat Message

Individual differences in processing information about a personal threat message about bisphenol A (BPA) risk were examined using the threat orientation model (Thompson &; Schlehofer, 2008 Thompson , S. C. , &; Schlehofer , M. M. ( 2008 ). Control, denial, and heightened sensitivity reactions to personal threat: Testing the generalizability of the threat orientation approach . Personality and Social Psychology Bulletin , 34 , 1070 – 1083 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Adults (N = 448) read a risk message concerning BPA in plastics. Threat orientations, intentions to protect oneself from BPA risk, and emotional and cognitive reactions to the message were measured. Individuals with different approaches to threat reached different conclusions about the message and used different information in that process. These findings suggest that consideration of individual differences could improve the predictive ability of existing theoretical models and the effectiveness of health and safety messages.     

Reactions to Feedback in Goal Choice and Goal Change Processes1

Two laboratory studies were conducted to test the effects of reactions to feedback on propensity to change an initial self-selected performance goal. In Study 1, the performance of 228 subjects on a word search task was manipulated by varying puzzle difficulty. In Study 2, two-dimensional goals (i.e., time and quantity) were first assigned and then chosen by 75 subjects. In Study 1, satisfaction with performance and self-efficacy predicted goal change beyond the effects of past performance. Subjects lower in both satisfaction and self-efficacy tended to lower initial goals, whereas those higher in either or both variables tended to raise them. In a post-hoc analysis, goal-performance discrepancies and motivational force interacted to explain satisfaction with performance for subjects experiencing negative feedback. This result was replicated in Study 2 for self-selected quantity goals. In Study 2, satisfaction with performance explained goal choice beyond the effects of past performance for initial time goals and final quantity goals. Trade-offs in the selection of dual goals occurred, with subjects selecting a difficult goal on one dimension and an easy goal on the other. Suggestions for future research and practice on self-regulation of goals and performance are provided.
