Emotional Contagion and Social Judgment

This study examined the influence of another's emotional expressions and individual differences in responsiveness to afferent feedback on attention, evaluations, and memory. In a mixed design, participants (N = 71) rated pictures following exposure to a sender in a neutral mood and then in either a happy or sad mood. Attention, ratings, and recall evidenced a bias characteristic of the sender's mood: Participants spent more time viewing happy and sad pictures following exposure to the happy and sad sender, respectively; ratings by participants exposed to the happy and sad sender were more positive and negative, respectively, and this effect was greater for those more cue-responsive; participants recalled more pictures congruent with the sender's mood and those more cue-responsive exposed to the sad sender exhibited impaired memory characteristic of the effect of sadness on memory. Findings suggest that exposure to even mild emotional expressions can influence cognition and behavior and this effect is greater for those more responsive to cues generated by afferent feedback.     

Social facilitation and inhibition of emotional expression and communication.

Does the presence of others facilitate or inhibit emotional expression? Female "senders" (n = 45) viewed 12 emotionally loaded slides either alone or with another sender while responses were secretly videotaped. In Study 1, 14 "receivers" guessed the type of slide viewed by dyads more accurately (eta = .366). In Study 2, 42 receivers viewed 10 senders with friends, 10 with strangers, and 10 alone. One dyad member was covered so that only 1 sender was visible. Analysis revealed significant effects of condition (alone, friend, or stranger; eta = .456), slide type (sexual, scenic, unpleasant, or unusual; eta = .325), and the Condition x Slide Type interaction (eta = .350). Strangers had overall inhibitory effects on communication accuracy, whereas friends had facilitative effects on some slides and inhibitory effects on others. Thus, both social facilitation and inhibition of expression occurred on the basis of the emotional stimulus and personal relationship involved.     

Do We Feel the Same Way If We Think the Same Way? Shared Attitudes and the Social Induction of Affect

Drawing on the literature on emotional mimicry, we argue that attitude similarity between a sender and a receiver influences the social induction of affect. Studies 1, 2, and 3 supported this reasoning by showing that similarity fostered, whereas dissimilarity blocked concordant reactions to a happy sender (but not to a sad sender). We also examined the mechanism behind these effects and found that similarity influenced liking of the happy sender but did not affect liking of the sad sender. Study 4 provided causal evidence for this idea by showing that similarity influenced the induction of positive affect through liking.     

Self-disclosure and liking: Effects for senders and receivers1

This experiment tested the social reward potential of self-disclosure and its impact on a receiver's attraction towards the sender. Further, a sender self-perception effect was tested. Just as a receiver is speculated to use the intimacy level of a disclosure as an indication of sender regard and trust, the self-perception hypothesis maintains that the sender also uses intimacy level to self-attribute liking and trust for the receiver. A forced-compliance procedure with college males was used to have a sender subject send either a high or low intimacy self-disclosure essay. Consistent with the social reward and self-perception hypotheses were measures of sender's behavior as trusting and measures of feelings during the disclosure process. General measures of liking and trust were not successful, however.     

Who is this?: Identity and presence in robot-mediated communication

Because a telepresence robot is intended for use in telecommunications, conveying the presence of a remote sender is an important issue. Even though certain characteristics of robots such as identity could be effective at generating a sense of presence, this risks yielding a distortion of presence in the remote sender. Thus, in order to find effective ways to increase presence, we executed an experiment comparing a telepresence robot with high identity and a telepresence robot with low identity. The 60 participants in this study engaged in a video call with a remote sender using either a telepresence robot with high identity or a telepresence robot with low identity. The results showed that participants felt more remote sender presence when interacting with the telepresence robot with low identity than they did with the one with high identity. On the other hand, when a telepresence robot has high identity, participants felt more presence toward the robot than they did toward the one with low identity. In the second study (N = 72), participants experienced two types of telepresence robots (identity level: a telepresence robot with high identity vs. a telepresence robot with low identity) with two types of remote senders (number of remote senders: single remote sender vs. multiple remote senders). The identity level of the robot and the number of remote senders affected the presence of the remote sender, telepresence, and the presence of the robot. We discuss in detail the implications for the design of telepresence robots in terms of increasing presence.     

The perception of eye contact

Ss made judgments of whether or not they were being looked in the eye as an E fixated several points on and off their faces.Distance between sender and receiver, sex, and whether the sender made a sequence of fixation sprior to the terminal fixation were variables of interest. The sender-receiver distance produced less effect than predicted from the hypothesis that receiver judgments were determined solely by the discrepancy between the sender’s iris/sclera configuration (ISC) during true eye contact and the current fixation point. There was no stable differencein accuracy as a function of whether the sender’s terminal fixation was preceded by other fixations or not. These findings cast doubt on the belief expressed in recent studies that the ISC can be used to accurately discriminate eye gazes from other gazes. The results also suggest that fixations on some portions of the face yield a judgment of eye contact which might be predicted on the basis of social experience.     

The development of a simple form of communication

This paper is concerned with situations in which one of two possible stimuli is presented to one subject, the sender, while a second subject is required to make one of two responses. The stimuli are not available to the receiver, but the latter can perceive the sender. Successful performance depends on the sender indicating what stimulus is present to the receiver. It is proposed that the development of this form of communication, initially observed with dolphins, can be understood in the light of recent autoshaping research. An experiment demonstrated that pairs of pigeons can learn to perform appropriately in such a situation and provided evidence supporting an autoshaping analysis.     

Some Effects of Role Conflict Source on the Experience of Role Conflict

A group of 176 undergraduates participated in a role-playing laboratory experiment that explored the effects of intersender and intrasender role conflict on experienced role stress. Each role sender's power (control over valued resources and outcomes) and importance (desire to meet the sender's expectations) were measured. For intrasender conflict only, role sender power was positively associated with upset over the conflict, whereas role sender importance was negatively associated with upset.

Sender Demeanor: Individual Differences in Sender Believability Have a Powerful Impact on Deception Detection Judgments

Sender demeanor is an individual difference in the believability of message senders that is conceptually independent of actual honesty. Recent research suggests that sender demeanor may be the most influential source of variation in deception detection judgments. Sender demeanor was varied in five experiments (N = 30, 113, 182, 30, and 35) to create demeanor–veracity matched and demeanor–veracity mismatched conditions. The sender demeanor induction explained as much as 98% of the variance in detection accuracy. Three additional studies (N = 30, 113, and 104) investigated the behavioral profiles of more and less believable senders. The results document the strong impact of sender effects in deception detection and provide an explanation of the low‐accuracy ceiling in the previous findings.     

Motivational cues: The role of perceived senders' self‐control ability in raters' deception judgements

Previous studies have found that senders' personal traits may be used by others to make judgements about the senders' truthfulness. Two studies were conducted to examine whether perceived self‐control ability has an effect on deception judgement. Perceived self‐control was hypothesized to act as a motivational cue that participants would use to assess the sender's motivation to lie, which in turn would influence their deception judgement. Results revealed that when participants assessed the sender as having higher self‐control ability, they would consider the sender to be less motivated to lie in daily life (Study 1), and judge the sender more truthful in a text‐based deception judgement task (Study 2). However, the effect of perceived self‐control ability disappeared in a video‐based task (Study 2), likely due to the multitude of various cues available in audio‐visual stimuli. The theoretical and applied implications of the results are discussed.     

A differing bidirectional impact on the recognition accuracy of facial expression

This study explored a bidirectional impact on the recognition accuracy of various facial expressions deriving from both the observer and sender in a sample of Chinese participants. A facial manipulation task was used to examine the ability of an observer's facial feedback to modulate the recognition of various facial expressions. Furthermore, the effect of a sender's facial expression with an open or closed mouth on recognition accuracy was investigated. The results showed that only recognition accuracy of a sad facial expression was influenced simultaneously by bidirectional sources from a sender and observer. Moreover, the impact of the unidirectional cue of a sender's facial feature (i.e., mouth openness) on happy and neutral faces was found to influence the recognition accuracy of these faces, but not the observer's bodily state. These findings indicate that the bidirectional impact derived from an observer and sender on facial expression recognition accuracy differs for emotional and neutral expressions.     

On the behavioral consequences of infrahumanization: the implicit role of uniquely human emotions in intergroup relations

Four experiments confirmed the hypothesis that people discriminate the out-group on the basis of the expression of uniquely human emotions. In Study 1, using a lost e-mail paradigm, the expression of a uniquely human emotion resulted in "nicer" replies when the sender was an in-group compared with an out-group member. The same pattern of results was obtained in Studies 2 and 3 using a conformity paradigm. In addition, perceived similarity was measured and proposed as a potential underlying mechanism (Study 3). Finally, using an approach-avoidance procedure, Study 4 showed that people not only deprive the out-group of positive consequences as in the former studies but that people also act against the out-group. The role of infrahumanization underlying prejudice and discrimination is discussed.     

Encoding and decoding nonverbal cues of emotion.

Subjects ("senders") encoded six emotions twice, first via facial expressions and second via tone of voice. These expressions were recorded and presented for decoding to the senders and an additional group of judges. Results were as follows: (a) the ability to encode and the ability to decode both visual and auditory cues were significantly related; (b) the relationship between encoding and decoding cues of the same emotion appeared low or negative; (c) the ability to decode visual cues was significantly related to the ability to decode auditory cues, but the correlations among encoding (and decoding) scores on different emotions were low; (d) females were slightly better encoders, and significantly better decoders, than males; (e) acquaintance between sender and judge improved decoding scores among males but not among females; (f) auditory decoding scores were higher than visual decoding scores, particularly among males; (g) auditory decoding scores were relatively high if sender and judge were of the same sex, while visual decoding scores were relatively high if sender and judge were of opposite sexes; (h) decoding scores varied according to channel of communication and type of emotion transmitted.     

Mind and Function in Animal Communication

Functional hypotheses about animal signalling often refer to mental states of the sender or the receiver. Mental states are functional categorizations of neurophysiological states. Functional questions about animal signals are intertwined with causal questions. This interrelationship is illustrated in regard to avian distraction displays. In purposive signalling, the sender has a goal of influencing the behavior of the receiver. Purposive signalling is innovative if the sender's goal is unrelated to the biological function of the signal. This may be the case in some instances of false alarm calling. Biological functionalism differs from philosophical functionalism in its concept of identity and in the specification of relevant inputs and outputs.

Evidence of heterospecific referential communication from domestic horses (<Emphasis Type="Italic">Equus caballus</Emphasis>) to humans

Referential communication occurs when a sender elaborates its gestures to direct the attention of a recipient to its role in pursuit of the desired goal, e.g. by pointing or showing an object, thereby informing the recipient what it wants. If the gesture is successful, the sender and the recipient focus their attention simultaneously on a third entity, the target. Here we investigated the ability of domestic horses (Equus caballus) to communicate referentially with a human observer about the location of a desired target, a bucket of food out of reach. In order to test six operational criteria of referential communication, we manipulated the recipient’s (experimenter) attentional state in four experimental conditions: frontally oriented, backward oriented, walking away from the arena and frontally oriented with other helpers present in the arena. The rate of gaze alternation was higher in the frontally oriented condition than in all the others. The horses appeared to use both indicative (pointing) and non-indicative (nods and shakes) head gestures in the relevant test conditions. Horses also elaborated their communication by switching from a visual to a tactile signal and demonstrated perseverance in their communication. The results of the tests revealed that horses used referential gestures to manipulate the attention of a human recipient so to obtain an unreachable resource. These are the first such findings in an ungulate species.

An adaptive perspective on revealed and concealed cues to empathy

Wu, Sheppard, and Mitchell (Br. J. Psychol., 2016; 107, 1‐22) found that observers could accurately identify people with extreme but not more average empathy scores. Here, we further consider this U‐shaped discrimination function. We first examine a statistical issue regarding the construction of the average groups, which are less homogenous by definition than the extreme groups. We then consider the kinds of questions arising when these results are considered within the adaptive framework of signal theory. Some interesting questions arise relating to the signal sender, including the costs and benefits to the sender in revealing and concealing true empathy levels, and the effects of adopting behavioural norms to conceal true levels of empathy.     

Increasing Deception Detection Accuracy with Strategic Questioning

One explanation for the finding of slightly above‐chance accuracy in detecting deception experiments is limited variance in sender transparency. The current study sought to increase accuracy by increasing variance in sender transparency with strategic interrogative questioning. Participants (total N = 128) observed cheaters and noncheaters who were questioned with either indirect background questions or strategic questioning. Accuracy was significantly below chance (44%) in the background questions condition and substantially above chance (68%) in the strategic interrogative questioning condition. The results suggest that transparency can be increased by strategic question asking and that accuracy rates well above chance are possible even for untrained judges exposed to only brief communications.
