The Media Bias Effect (MBE) represents the biasing influence of the nonverbal behavior of a TV interviewer on viewers' impressions of the interviewee. In the MBE experiment, participants view a 4-min made-up political interview in which they are exposed only to the nonverbal behavior of the actors. The interviewer is friendly toward the politician in one experimental condition and hostile in the other. The interviewee was a confederate filmed in the same studio, and his clips are identical in the two conditions. This experiment was used successfully in a series of studies in several countries (Babad and Peer in J Nonverbal Behav 34(1):57-78, 2010. 10.1007/s10919-009-0078-x) and was administered in the present research. The present investigation focused on the interviewer's source credibility and its persuasive influence. The viewers filled out questionnaires about their impressions of both the interviewer and the interviewee. A component of "interviewer's authority" was derived in PCA, with substantial variance in viewers' impressions of the interviewer. In our design, we preferred the conception of Epistemic Authority (Kruglanski et al. in Adv Exp Soc Psychol 37:345-392, 2005)-based on viewers' subjective perceptions for deriving authority status-to the conventional design of source credibility studies, where dimensions of authority are pre-determined as independent variables. The results demonstrated that viewers who perceived the interviewer as an effective leader demonstrated a clear MBE and were susceptible to his influencing bias, but no bias effect was found for viewers who did not perceive the interviewer as an effective leader. Thus, Epistemic Authority (source credibility) moderated the Media Bias Effect.

Physical attractiveness is a heuristic that is often used as an indicator of desirable traits. In two studies (N = 1254), we tested whether facial attractiveness leads to a selective bias in attributing moral character—which is paramount in person perception—over non-moral traits. We argue that because people are motivated to assess socially important traits quickly, these may be the traits that are most strongly biased by physical attractiveness. In Study 1, we found that people attributed more moral traits to attractive than unattractive people, an effect that was stronger than the tendency to attribute positive non-moral traits to attractive (vs. unattractive) people. In Study 2, we conceptually replicated the findings while matching traits on perceived warmth. The findings suggest that the Beauty-is-Good stereotype particularly skews in favor of the attribution of moral traits. As such, physical attractiveness biases the perceptions of others even more fundamentally than previously understood.

Verbal irony is a rhetorical device that is not only verbal but also paraverbal. In the present study, we explored the paraverbal expression of verbal irony which has been largely underinvestigated, especially facial expressions. Given the role played by facial expressions in the detection of emotions, we hypothesized that speakers can communicate irony by facial expression alone. We asked 104 speakers to pronounce the same utterance, sometimes ironically, sometimes not. Naive judges were able to detect which speakers were ironic with increasing accuracy across the following three conditions: prosody only, facial expressions only, and both prosody and facial expressions. We then undertook a systematic description of the utterances, to identify which paraverbal cues induced the highest ironicalness ratings among the judges. Slow speech rate, then expressive movements of the mouth, then eyebrow flashes were the three most influential cues. Overall, facial cues explained more variance than vocal cues. Our results did not support the existence of a single, specific set of paraverbal ironic cues. They did, however, show that speakers routinely produce paraverbal cues, and that these cues, especially facial ones, allow their irony to be detected. The implications for models of irony comprehension are discussed.

The role of face and context in emotion perception was investigated by manipulating features relevant to the stimuli and to the observer. A nested-stimulus design was used, with subjects nested under stimulus item (an encoder’s facial expression or a written emotion-eliciting scenario presented alone or in an incongruent pair) and type of task instruction (judgment of encoder’s expressed or felt emotion). Subjects, using one type of task instruction, completed a decoding task in which they viewed a facial expression, a written scenario, or a facial expression paired with an emotion-incongruent scenario. Type of task instruction was intended to alter subjects’ perception by directing attention to favor face information (judgment of expressed emotion) or context information (judgment of felt emotion). Then subjects selected the predominant emotion and indicated the intensity of various emotions they perceived the encoder to be expressing or feeling. Judgments were examined for target emotion match to face and/or context using a by-stimulus analysis. The results suggest that when an encoder’s facial expression is discordant with the emotion-eliciting event, subjects will favor facial information when judging what the encoder is expressing, whereas they will favor context information when judging what the encoder is feeling. When face or context was seen alone, type of task instruction did not influence subjects’ judgments. This research provides a more detailed understanding of the role of face and context by exploring how features associated with the observer-encoder interaction influence emotion perception.
