This study investigated the factor structure of source credibility within the context of three situations in which communication typically occurs. The study tested the hypothesis that the situation in which the speaker communicates will influence the receiver's perception of the dimensions underlying the credibility of that speaker. The results indicated that the factor structure of source credibility across situations was variant. The scales used to measure the factors of trustworthiness and expertness may reflect more than one perceptual element for the receiver. The study indicated further that different types of communication in the same situation yield different source credibility factor structures. 相似文献

A general paradigm of a rating error theory is presented with a study testing relationships from the theory. The study aimed to discover the effects of source credibility, attitude valence, and task sensitization on trait errors in the evaluation of speeches. The main hypothesis of the study was an interaction effect on trait errors in the speech ratings. The results indicate a significant triple interaction, suggesting that when speech raters are sensitized to the task and are in favor of the view of the speaker, their trait errors on “ideas” will favor a low credibility speaker. The results are explained in terms of attraction and similarity. 相似文献

This study examines credibility perceptions in online consumer reviews. Specifically, this work investigates the effects of review emotionality (high vs. low), review valence (positive vs. negative), and individuals’ need for affect on source credibility and information credibility. In an online experiment, U.S. adults (N = 327) viewed a product review from Amazon.com varied across four experimental conditions. Results indicate that high-emotionality reviews are perceived as lower in source and information credibility compared to low-emotionality reviews. A moderated mediation model was tested with the source credibility dimensions as possible mediators of information credibility and need for affect as a moderator for the effects of review emotionality. The effects of emotionality on information credibility were significantly mediated by source trustworthiness, and this mediation was moderated by participants’ need for affect, with the credibility-hampering effects of emotionality found only among participants with low and moderate levels of need for affect. 相似文献

The purpose of this study was to assess the effects of rhetorical equivocation on a speaker s credibility ratings. Subjects were presented one of four messages which either equivocated the issues or spoke clearly to the issues. The results indicated that listeners conferred more credibility on those who agreed with them and less on those who disagreed with them. 相似文献

An experiment investigated if graphic censorship disclaimers affect memory or thought elaboration for television news stories of the 1991 Persian Gulf war. Viewer assessment of the credibility of censored news also was considered. Subjects listed their thoughts about each story, and their memory was tested as recognition latency. Subjects who rated the credibility of censored news as moderate scored highest on the memory task, but listed the fewest number of negative mentions about the government named as censor in the stories. Under some conditions, results show that the more viewers thought about the source of the censorship, the lesser they remembered images from the stories. 相似文献

ABSTRACT By administering an online experiment, this study examined how source and journalistic domains affect the perceived objectivity, message credibility, medium credibility, bias, and overall journalistic quality of news stories among an adult sample (N?=?370) recruited using Amazon’s Mechanical Turk (MTurk) service. Within the framework of the cognitive authority theory, the study found auto-written news stories were rated as more objective, credible (both message and medium credibility), and less biased. However, significant difference was found between a combined assessment condition (news stories with source and author information) and a message only assessment condition (news stories without source and author information) in the ratings of objectivity and credibility, but not bias. Moreover, significant differences were found in the objectivity and credibility ratings of auto-written and human-written news stories in the journalistic domains of politics, finance and sports news stories. In auto-written news stories, sports news stories were rated more objective and credible, while financial news stories were rated as more biased. In human-written stories, financial news stories were rated as more objective and credible. However, political news stories were rated as more biased among human-written news stories, and in cases where auto-written and human-written stories were combined. 相似文献

ABSTRACTMany news organizations have developed policies on the use of named and unnamed sources, including whether the latter can be directly quoted or paraphrased in news stories. In this experiment, we test how audience members respond to these policy dictates by measuring news credibility in a political story that manipulated whether the source was named, whether that source was directly quoted, and the source’s political connection to the story. We found that while each of these manipulations had little or no main effects, they combined to trigger a discernible change in credibility in the eyes of the audience. 相似文献

This study examined how violations of listeners’ expectancies of the strength of speakers’ foreign accents influence evaluations of foreign-accented speakers. Participants (N = 275) listened to a male or female speaker reading a short passage in Spanish-accented English. Compared to participants whose expectancies about the strength of speakers’ foreign accents were confirmed, listeners whose expectancies were negatively violated reported a more negative affective reaction and attributed less status to the speaker. Affect partially mediated the effect of negative expectancy violations on ratings of status. Participants whose expectancies were positively violated did not differ from those whose expectancies were confirmed on any dependent measures. 相似文献

Male and female university students and non‐students heard audiotapes containing a combination of two antagonistic persuasive speeches on the energy crisis: one with 12 obscene phrases, one with 12 parallel, non‐obscene phrases; one by a male speaker, one by a female; one pro‐environmentalists, one pro‐oil companies. Listener attitude was assessed on three dimensions using the Speech Dialect Attitudinal Scale. Analyses indicated that speakers were rated lower on Socio‐Intellectual Status and Aesthetic Quality when they used obscene language than when they did not; however, no difference was found on Dynamism. Other findings regarding speaker sex, listener group, and listener sex are discussed. 相似文献

Two experiments tested the prediction that heavy foreign-accented speakers are evaluated more negatively than mild foreign-accented speakers because the former are perceived as more prototypical (i.e., representative) of their respective group and their speech disrupts listeners’ processing fluency (i.e., is more difficult to process). Participants listened to a mild or heavy Punjabi- (Study 1) or Mandarin-accented (Study 2) speaker. Compared to the mild-accented speaker, the heavy-accented speaker in both studies was attributed less status (but not solidarity), was perceived as more prototypical of their respective group, disrupted listeners’ processing fluency, and elicited a more negative affective reaction. The negative effects of accent strength on status were mediated by processing fluency and sequentially by processing fluency and affect, but not by prototypicality. Theoretical, methodological, and practical implications are discussed. 相似文献

This study investigated the variability of scales representing four factors of source credibility and the overall factor structure of subjects’ perceptions of and attributions to a message source. The results confirmed the hypotheses that (1) scales representing factors of source credibility will change over time, and (2) the factor structure (the number of significant factors and the amount of variance accounted for by the factors) would also change over time. The authors suggest that if the view is accepted that communication is an ongoing dynamic process, then an individual's experiences in the communication setting and the variables affecting perceptions of the process will be expected to change continually. 相似文献

This study attempted to determine the amount of variance in attitude intensity that could be expected to be accounted for by prior attitude and credibility. Prior attitude intensity, importance, and involvement along wth source competence, sociability, composure, extroversion, and character were used as ‐predictors. Multiple regression analysis revealed that between 61 and 66 per cent of the variance in attitude intensity can be accounted for by five of these variance in attitude intensity can be accounted for by five of these predictors (except prior attitude involvement, source composure, source character). Some of the predictors appear to account for variance through curvilinear relationships to attitude change. 相似文献

This study tested the generalizability of previous research concerning inoculation against counterpersuasion when the counterpersuasive influence is exerted in a small group communication context. Earlier findings indicated that a two‐sided message which includes refutation of opposing positions or which includes documented supporting material tends to inoculate receivers against counterpersuasion in a confrontation setting. Results indicated that a two‐sided message produced more attitude change after counterpersuasion than did a one‐sided message. Evidence effects in the present study were significant at only the .10 level, but in the hypothesized direction. Message sidedness had no significant effect on perceived source credibility. Inclusion of evidence significantly increased perceived source credibility on the authoritativeness dimension. 相似文献

ABSTRACTCourses: This activity is designed specifically for public-speaking courses, but it could be used in the general introductory communication course. It also holds potential for use in persuasion, argumentation, or strategic communication courses.Objectives: This activity helps students understand audience as a more complicated concept—one that recognizes the power of a speaker in creating and challenging communities and interrogating power through their performative speeches in the courses named above. 相似文献

ABSTRACTThis study explored the relationship between the four dimensions of students’ feedback orientation (i.e., utility, retention, confidentiality, and sensitivity) and the four dimensions of students’ classroom engagement (i.e., silent in-class, oral in-class, thinking about course content, and out-of-class) using the tenets of Feedback Intervention Theory (FIT) as a guide. Participants were 208 undergraduate students enrolled in a variety of introductory communication courses at a large mid-Atlantic university. It was found that varying combinations of students’ feedback orientation influence students’ engagement, providing further support for FIT. Specifically, feedback utility was positively related to all four dimensions of student engagement. Furthermore, feedback confidentiality was negatively related to oral in-class behaviors. Future research should continue to examine the influence of instructional feedback on students’ classroom engagement. 相似文献

ABSTRACT This experiment (N= 476) investigates how individuals evaluate political candidates who use informal communication on social media. We use expectancy violations theory (EVT) to predict that informal communication will lead to negative evaluations. Our results suggest that politicians’ use of informal communication on social media leads to expectancy violation, which decreases perceived credibility and lessens intention to support a candidate. This effect was not moderated by sex (male versus female) or age (young versus old) of the candidate, nor of participants being the same sex as the candidate. These findings suggest that political figures should use informal communication on social media with caution. 相似文献

This re‐examination of Richard Brinsley Sheridan's two speeches against Warren Hastings appraises the spectacular success of the impeachment speech of 1787 and the relative success of the rephrased version delivered at Hastings’ trial in 1788. It also assesses factors that may have influenced later observers who reacted to the speeches with considerably less enthusiasm than did Sheridan's listeners. In maintaining that Sheridan's view of Hastings was consistent and justified, the author questions the continuing criticisms of Sheridan's motives in the Hastings affair. The conclusion considers why Sheridan's two speeches have probably failed as literature, and hence indirectly suggests why other speeches may have gained literary stature. 相似文献
