Theories of deception have produced upwards of 150 potential verbal and nonverbal communication indicators. Of these, approximately 30 indicators, or cues, have been used previously with automated linguistic analysis tools to study text-based communication. The current research examines the interrelationships among these cues and proposes a set of specific constructs to be validated for high-stakes deception research. We analyzed linguistic-based cues extracted from 367 written statements prepared by suspects and victims of crimes on military bases. Confirmatory factor analysis was used to evaluate two models. The superior model retained seven constructs: quantity, specificity, affect, diversity, uncertainty, nonimmediacy, and activation.  相似文献

As part of an ongoing research program investigating features of computer-mediated communication (CMC) that affect deception and its detection, an experiment was conducted to test the impact of synchronicity on communication processes, credibility assessments, deception detection, and team performance. At issue is whether various forms of CMC enable or deter successful deception. Synchronous (real-time) CMC was hypothesized to foster more involvement and mutuality during communication, more credibility for team members, and hence less detection of deception when it was present. Team performance was hypothesized to suffer under deception due to deceivers capitalizing on synchronous communication to build their credibility. Two-person teams conducted a decision-making task in real time (synchronous) or over the course of several days (asynchronous). In half of the pairs, one party was asked to be deceptive. The results indicated that participants in the synchronous mode were more involved, perceived more mutuality, and viewed their partners in a more favorable light, than participants in the asynchronous mode. Deceivers portrayed themselves as somewhat more credible than truthtellers. However, they were not perceived as more persuasive than truth-tellers. Participants in the deceptive condition made poorer decisions than participants in the truthful condition. Implications for CMC and future study are discussed.  相似文献

This study examines the influences of norms on consumers’ intentions to watch online video ads on social media. The social norms approach and the theory of reasoned action (TRA) were adopted as theoretical frameworks. In addition, the effects of interpersonal and social influences on the three personal-level norms were examined as the antecedents of normative perceptions. To test the hypothesized model, an online survey was conducted with 313 undergraduate students. A confirmatory factor analysis was used to validate the measurement constructs of the model, and a structural equation modeling was used to identify the relationships among constructs in the model. Findings indicate that personal injunctive norms and subjective norms were positively related to consumers’ intention to watch online video ads. Interpersonal and social influences were positively related to three normative perceptions regarding online video ad watching. The findings of this study contribute to the research stream on social norms approach and TRA and provide practical implications for advertising and marketing practitioners.  相似文献

Abstract

In an attempt to reconcile past modality research, Leigh (1991) used Multiple Resource Theory while emphasizing the role of audio / visual congruency and task difficulty. This paper provides an alternative interpretation by reviewing Multiple Resource Theory from an involvement perspective. Past modality studies are organized and integrated based on the level of consumer involvement in the stimulus ad. Empirical findings are shown to be highly consistent with this approach. Suggestions for future modality research are presented.  相似文献

Abstract

The authors report the findings of an experiment that investigated the influence of television programs on viewers' perceptions of television commercials. Specifically, program arousal and program pleasantness were examined as potentially important determinants of viewers' emotional responses to advertising. The experiment used a two (levels of program arousal) by two (levels of program pleasantness) design to assess the effects of the independent variables on viewers'perceptions of commercial pleasantness for a pod of four commercials. As hypothesized, an assimilation effect occurred in the high arousal condition and a contrast effect occurred in the low arousal condition. Implications of these results for researchers and practitioners are discussed.  相似文献

Scholars have assumed that trust is fragile: difficult to build and easily broken. We demonstrate, however, that in some cases trust is surprisingly robust—even when harmful deception is revealed, some individuals maintain high levels of trust in the deceiver. In this paper, we describe how implicit theories moderate the harmful effects of revealed deception on a key component of trust: perceptions of integrity. In a negotiation context, we show that people who hold incremental theories (beliefs that negotiating abilities are malleable) reduce perceptions of their counterpart’s integrity after they learn that they were deceived, whereas people who hold entity theories (beliefs that negotiators’ characteristics and abilities are fixed) maintain their first impressions after learning that they were deceived. Implicit theories influenced how targets interpreted evidence of deception. Individuals with incremental theories encoded revealed deception as an ethical violation; individuals with entity theories did not. These findings highlight the importance of implicit beliefs in understanding how trust changes over time.  相似文献

With the rapid growth of electronic commerce, there is growing demand forremote online negotiations. Although the Internet now enables audio and video communication, most Web-based negotiation systems are still text-based. There is, however, a lack of research on the effects of multimedia on remote negotiations. In this paper, we present a theoretical model to investigate the impacts of multimedia communication in an online negotiation setting. The constructs in our model include communication efficiency, communication effectiveness, and positive and negative social-emotional communication. Through a simulated house purchasing negotiation experiment, we study how different multimedia combinations (text only; text with audio; text with audio and video) affect our constructs and thus further influence negotiation results. Our results showed that both text with audio and text with audio and video communication were significantly preferred to text alone. However, the addition of video to text and audio communication in a negotiation environment was not found to be beneficial. It did not significantly improve communication efficiency, effectiveness or positive social-emotional communication, but distracted negotiators from focusing on the negotiation task. Our analysis also revealed that the communication efficiency construct did not correlate with the perceived success of the negotiation solution; however communication effectiveness and social-emotional communication did correlate with negotiation satisfaction.  相似文献

The purpose of this study was to examine the effects of various online visual merchandising (VMD) cues—high and low task relevant cues—on consumer pleasure and arousal under different situational involvement (browsing vs. purchasing). A random sample of 1634 female college students participated in an experiment in the context of online apparel shopping. The results of the study revealed a significant effect for high task relevant cues on pleasure and arousal under high situational involvement (purchasing situation). In addition, a significant effect for low task relevant cues on pleasure and arousal under low situational involvement (browsing situation) was found. Pleasure and arousal induced by various online VMD cues were positively related to consumer satisfaction, purchase intention, and approach behavior. The findings of the study emphasize a significant role of VMD cues on apparel Web sites, influencing pleasure and arousal, which in turn increase consumer satisfaction, purchase intention, and approach behavior. The study also provides an important implication for online apparel retailers developing Web sites that may attract both online browsers and purchasers. ©2010 Wiley Periodicals, Inc.  相似文献

In this article, we examine the role of several consumers’ cognitive and psychographic traits in their perceptions of retailers’ deceptive practices (perceived deception) and the different effects on perceived deception associated with online vis-à-vis in-store shopping. Building on theoretical models of persuasion in consumer behavior, we hypothesize that the antecedents of perceived deception in traditional settings are the same as those on the Internet, while the intensity of the impact of these antecedents differs between the online and the offline environment. Results suggest that the effects of individual’s cognitive traits (Internet-based information search and perceived Internet usefulness) and risk aversion on perceived deception are more relevant when consumers shop online than when they purchase from traditional stores. Conversely, psychographic traits (shopping enjoyment and materialism) play a more important role in explaining perceived deception in the traditional shopping context as compared to the online channel. Several theoretical and managerial implications are derived from these findings.  相似文献

This article is a report of results of three studies investigating effects of fast versus slow background musical tempo on physiology, cognition, and emotions. Two pilot studies first measure consumer perceptions of tempo. In Studies 1 and 2, participants view a short video restaurant advertisement featuring fast or slow background music along with illustrations of food items. Results indicate that fast music is more effective than slow music for evoking positive taste expectations and purchase intentions. Study 3 shows that the effects observed in Studies 1 and 2 occur because fast music enhances self-reported arousal levels that then lead to enhanced moods, taste expectations, and purchase intentions. Theoretical implications regarding effects of music on emotional responses are discussed, as are practical managerial implications for using fast music as a persuasive technique.  相似文献

Using the pleasure, arousal, and dominance (PAD) model, this study seeks to extend existing knowledge about consumers' activities in online retail environments by focusing on the largely ignored role of perceived dominance. In online environments, perceived dominance might influence purchasing intentions both directly and indirectly through pleasure. Furthermore, consumers' perceptions of Web site atmospherics (informativeness, navigational cues, perceived organization, and entertainment) likely affect two dimensions of emotion (perceived dominance and arousal). This study also investigates the moderating effects of situational involvement on the relationships among the PAD dimensions for online consumers. The results affirm that perceived dominance has direct effects on purchasing intentions, as well as indirect impacts through pleasure. The impact of perceived dominance on pleasure also is moderated by situational involvement. Whereas high task-relevant cues exert significant effects on perceived dominance, low task-relevant cues influence arousal. Therefore, this research shows that perceived dominance relates to online customers' purchasing intentions, which represents an extension of existing knowledge about the PAD model applied online; it also provides notable managerial implications for e-marketers.  相似文献

Whether or not an advertisement is said to be deceptive depends on the understanding and definition of deception being used. The position advocated here is that the focus of any definition must be the receiver of the message. Based on an analysis of veridical perception, a definition of deception in advertising is offered. An approach to measuring deception is also offered. The techniques are all seen as screening techniques, although by their regular use, advertisers should improve the ability of their advertisements to reach their stated objectives as well as reduce the amount of deception.  相似文献

The detection of deception is a promising but challenging task. A systematic discussion of automated Linguistics Based Cues (LBC) to deception has rarely been touched before. The experiment studied the effectiveness of automated LBC in the context of text-based asynchronous computer mediated communication (TA-CMC). Twenty-seven cues either extracted from the prior research or created for this study were clustered into nine linguistics constructs: quantity, diversity, complexity, specificity, expressivity, informality, affect, uncertainty, and nonimmediacy. A test of the selected LBC in a simulated TA-CMC experiment showed that: (1) a systematic analysis of linguistic information could be useful in the detection of deception; (2) some existing LBC were effective as expected, while some others turned out in the opposite direction to the prediction of the prior research; and (3) some newly discovered linguistic constructs and their component LBC were helpful in differentiating deception from truth.  相似文献

While prior scholarship has acknowledged the overall positive influence of vanity sizing on consumer outcomes, no work to date has addressed the psychological process that occurs when consumers suspect retailers of dishonest sizing information. This is an important process to understand because perceptions of deceptive retailer motives lead consumers to react negatively to the product and the retailer, regardless of the retailer's actual motives. Thus, this research utilizes attribution theory to examine perceived deception as a mediator between consumer cynicism (a dispositional trait) and consumer outcomes. The results reveal that at higher levels of consumer cynicism, prior knowledge of deceptive sizing practices has an amplifying effect on the influence of consumer cynicism on perceived deception, while retailer honesty with sizing issues helps to block this influence. Further, perceived deception leads to reduced consumer outcomes, confirming prior findings in the literature.  相似文献

This study investigated attitudes toward the use of deception in negotiation, with particular attention to the distinction between deception regarding the informational elements of the interaction (e.g., lying about or misrepresenting needs or preferences) and deception about emotional elements (e.g., misrepresenting one’s emotional state). We examined how individuals judge the relative ethical appropriateness of these alternative forms of deception, and how these judgments relate to negotiator performance and long-run reputation. Individuals viewed emotionally misleading tactics as more ethically appropriate to use in negotiation than informational deception. Approval of deception predicted negotiator performance in a negotiation simulation and also general reputation as a negotiator, but the nature of these relationships depended on the kind of deception involved.  相似文献

This study examines whether consumers' perceptions of corporate social responsibility (CSR) activities can predict behavioral loyalty, and how two attitudinal constructs drawing from the means-end chain model—involvement and commitment—mediate this relationship. A field study of 634 customers of an Australian professional football team was conducted by combining attitudinal surveys with actual behavioral data collected one year later. The results revealed a positive mediating effect of involvement on the relationship between perceived CSR and behavioral loyalty. However, when the effect of involvement on behavioral loyalty was mediated by commitment, the indirect effect of perceived CSR turned negative. The findings of this study indicate that the contribution of CSR initiatives to behavioral loyalty is not as robust as past research suggests, and is also contingent upon specific psychological states activated by consumers' perceptions of such initiatives.  相似文献

The voice is often the only continuous channel of expression in pitch videos. We isolate the influence of entrepreneurs' vocal expressions on funding by examining how valence (positivity/negativity) and arousal (activation) shape funders' perceptions of passion and preparedness. We show that an entrepreneur's high-arousal vocal expressions, whether positive or negative, increase perceptions of their passion. Entrepreneurs are perceived as more prepared when the valence and arousal of their vocal expressions are congruent. We test our hypotheses in the context of rewards-based crowdfunding, using both an experiment and a speech affect analysis of real-world crowdfunding pitches.  相似文献
