Nonverbal strategies for decoding deception

This study tested the hypothesis that judges who suspect deception would be less influenced by controllable channels (facial expresions) relative to leaky channels (voice and body) than judges who do not suspect deception. The Nonverbal Discrepancy Test, comprised of video (face or body) cues paired with audio cues, was administered to subjects with the information that the person shown in the test never lied, sometimes lied, or very often lied; in a fourth condition (control) there was no mention of deception. In some cases, the video and audio components of the discrepancy test depicted the same affect while in other cases they depicted different affects. Subjects who expected more deception were relatively less influenced by the facial component of the affectively discrepant video-audio pairings. These subjects were also less accurate at decoding affectively consistent videoaudio pairings, especially those involving facial cues. Finally, subjects who expected more deception became less accurate decoders of consistent video-audio pairings during the second half of the test but learned to recognize video-audio discrepancies better. The results suggest that suspicion of deception led subjects to discount facial cues. Results for the control group indicated that even in the absence of explicit information, discrepant messages create a suspicion of deception.Preparation of this paper was supported in part by the National Science Foundation.     

Effects of gaze on hiring,credibility, attraction and relational message interpretation

Two competing models of the social meaning and effects of eye gaze exist. One holds that different levels of eye gaze have clearly identifiable meanings that will yield main effects on such communication outcomes as hiring and interpersonal evaluations. The other holds that deviant levels of eye gaze are ambiguous in meaning and that interpretation depends on contextual cues such as the reward value of the violator. An experiment required 140 Ss to serve as interviewers during a structured interview in which six confederate interviewees sytematically varied three levels of eye gaze (high, normal, low) and two levels of reward (highly qualified, highly unqualified for the advertised position). Results favored a social meaning model over a violations of expectations model: Subjects were more likely to hire and rate as credible and attractive interviewees who maintained a normal or high degree of gaze than those who averted gaze. Interpretations given to higher amounts of gaze were more intimacy and similarity, more immediacy and involvement, and more composure, informality and nonarousal.

The Social Psychophysics of Cooperation: Nonverbal Communication in a Public Goods Game

An experiment was conducted to test the hypothesis that cooperation in a social dilemma context could be facilitated by inducing participants to emit social psychophysical cues, information in the perceptual array that affords meaningful and consequential social inferences. In particular, participants were asked to engage in mutual eye gaze, to touch one another gently, to communicate in a virtual chat room, or to tap out rhythms in synchrony. All but the last of these manipulations increased contributions to a public good in all-male but not all-female groups. These results suggest the inference systems that are engaged when individuals make decisions about whether or not to cooperate in a group context are responsive to relatively low level nonverbal behavioral cues.     

Sibling resemblances in nonverbal skill and style

This study explored the hypothesis that siblings display a tendency for family resemblance in nonverbal decoding skills. Thirty-seven sibling pairs between the ages of 9 and 15 were administered the videotaped Nonverbal Discrepancy Test. This audiovisual test assesses (1) decoding accuracy—the extent to which subjects are able to identify affects (positivity and dominance) from face, body, and tone of voice cues; (2) discrepancy accuracy—the extent to which subjects recognize the degree of discrepancy between audio and video cues; and (3) video primacy—the extent to which subjects are more influenced by video (face or body) than by audio cues. Brother-brother pairs showed family resemblances in all three nonverbal indices, whereas brother-sister pairs displayed family similarity only in discrepancy accuracy. Overall, sibling pairs showed a tendency for family resemblance in nonverbal decoding. The processes that might lead siblings to develop similar patterns of nonverbal skills were discussed.     

Attributional asymmetries in the perception of moving,static, chimeric and hemisected faces

Recent research on asymmetries of facial recognition, emotional interpretation and expression was extended in three studies of facial personality attribution. Male and female judges used 10 adjectives to compare the bilateral aspects of 24 female faces, presented on video. Static (and live) chimeric images elicited more marked differences in personological attribution to the two sides of the face than did moving chimerics. Chimeric and hemisected moving images elicited a similar extent of differential attribution. Cross-validation data indicated that, as hypothesized, left face tended to be seen more often as receptive, intuitive, feeling, pleasant, happy and right-face as outgoing, active, thinking, strong. Aspects of facial asymmetry and its measurement are discussed.This study was supported by the Social Science Research Council (HR 5413).

Big girls don't frown,big boys don't cry—Gender differences of professional actors in communicating emotion via facial expression

It was tested whether professional actors would be able to communicate emotional meaning via facial expression when this is presented to judges without context information. Forty takes were selected from movies, depicting a female or a male actor in close-up showing facial expression. These close-ups were selected by two expert judges, who knew the complete movie and had to agree on the emotion expressed or expected to be expressed by the female or male actor in the respective take. Five takes each were selected to represent the basic emotions of joy, sadness, fear, and anger. Twenty takes each were selected showing female and male actors. These 40 takes (edited in random order onto video tape) were presented to 90 judges (about half female and half male; about half younger pupils and about half older ones), whose task it was to judge the emotion(s) expressed on nine 5-point-emotion scales. Results indicated that female actors are somewhat better (though not statistically significant) in communicating emotion via facial expression without context than male actors are. Furthermore, significant interactions between portrayed emotion and gender of actors were found: While recognition rate for joy is very high and identical for both genders, female actors seem to be superior in communicating fear and sadness via facial expression, while male actors are more successful in communicating anger. A display rule approach seems to be appropriate for the interpretation of these results, indicating that gender-specific attempts to control/inhibit certain emotions do not only exist in real life, but also in movies.The research reported here was supported by a grant of the Deutsche Forschungsgemeinschaft (WA 519/2-2).

Do Actions Speak Louder Than Words? Preschool Children's Use of the Verbal-Nonverbal Consistency Principle During Inconsistent Communications

The present study investigated whether preschool children could use the conventional actions speak louder than words principle (or the verbal-nonverbal consistency principle) to process information in situations where verbal cues contradict nonverbal cues. Three-, 4-, and 5-year-olds were shown a video in which an actor drank a beverage and made a verbal statement (e.g., I like it) that was inconsistent with her emotional expression (e.g., frowning), and were asked whether the actor liked or disliked the beverage. If children used the verbal-nonverbal consistency principle, they should respond according to the information conveyed by the actor's emotional expression. Results showed that when the message was more naturalistic, the majority of children tended to respond based on the actor's verbal message. However, when the inconsistency between the verbal and nonverbal messages was made salient, more children appeared to rely on the nonverbal cue. Younger children's reliance on verbal cues reported in previous research may be partly explained by the salience of the verbal message.     

Video lottery gambling: Effects on pathological gamblers seeking treatment in South Dakota

Fifty-eight pathological gamblers receiving treatment for addictive illness in two South Dakota hospitals were assessed for types of gambling and grouped into three categories; 15 video lottery only (VLO), 36 video lottery mixed (VLM), and 7 not video lottery (NVL). There were 51 male and 7 female respondents, with a mean age of 38.2. We hypothesized that video lottery would be the predominant type of gambling on several dimensions: level of recent activity, most money lost on one occasion, and number of DSM-IV criteria met. Of all gamblers, 87.9% had pathological involvement with video lottery. Video lottery gambling accounted for the highest level of recent activity. In the VLM group, video lottery gambling led to greater single-occasion monetary losses. In addition, significantly more DSM-IV criteria were met in the VLM group for video lottery gambling than for other forms of gambling these subjects had engaged in. Results indicate that video lottery gambling is the predominant type of gambling behavior engaged in by gamblers seeking treatment for addictive illness in South Dakota. We propose that these findings could be associated with the availability and stimulus differences between video lottery and other gambling types.The authors would like to thank Larry Atwood, Chemical Dependency Counselor at Keystone Treatment Center in Canton, S.D., for his assistance with data collection.     

Eye-contact as a chance product of individual looking: Implications for the intimacy model of argyle and dean

From time to time during social encounters, people look at one another in the region of the eyes, and sometimes their eyes meet to make eye-contact. According to Argyle and Dean (1965), eye-contact in dyadic encounters signals the intimacy of the interaction and is controlled largely by the competing approach and avoidance forces that motivate the pair. In the present paper, new analyses are reported of three published experiments that were designed originally to test aspects of the intimacy model and it is shown that the duration of eye-contact is no more than a chance product of how long the two subjects look individually. Looking and not eye-contact, it is argued, should be the basis for models of visual interaction, and the intimacy model is ill-founded conceptually; the role of emotion in gaze has been overstressed at the expense of the concept of information; and the most important aspect of vision is in any case not looking and eye-contact but visual access to the whole person. The more cueless the encounter—that is, the fewer the social cues from vision and all the other senses combined—the greater the psychological distance; and the greater the psychological distance, the more task-oriented and depersonalized the content of what people say and, in turn, the less spontaneous their style of speech and the less likely a debate to end in compromise.Research for this article was sponsored by the Social Science Research Council of Great Britain.     

Nonverbal response patterns in physician-patient interactions: A functional analysis

In this paper, we examined physician-patient interactions in terms of the communicative functions accomplished during these encounters. Specifically, the nonverbal communicative exchanges of 38 physician-patient interactions in a family practice clinic were investigated. Two distinctive communicative patterns characterized these interactions. First, physicians nonverbally exerted greater dominance and control by employing longer speaking turns, more social touch, and more pauses while speaking than did the patients. Secondly, physicians and patients tended to reciprocate nonverbal behaviors signalling affiliation including gaze, response latencies, body orientations, and gestures. Consistent with previous research, there was a strong positive relationship between patients' satisfaction with health care and perceptions of the physicians' affiliativeness. Although there were few significant effects, physicians perceived less affiliative tended to be more vocally and gesturally active relative to the patients' nonverbal behavior styles. Finally, there were positive relationships between patients' perceptions of physicians' dominance and the physicians' use of task touch, and the extent to which physicians produced more interruptions and maintained more indirect body orientations relative to the patients' performances of these behaviors. The results are discussed in terms of the communicative functions of nonverbal behavior in physician-patient interactions and of patients' preferences for physicians' nonverbal expressiveness.The authors wish to thank Joe Cappella, Howard Waitzkin, Martha Davis, and William B.

“Just a hunch”: Accuracy and awareness in person perception

Person perception tasks involving nonverbal communication have a mystified reputation. It is frequently argued that nonverbal cues are accurately, but only unconsciously, perceived. This may explain the frequent response of judges who, when asked to decode a sample of nonverbal behavior, reply that it was just a hunch—i.e., show little or no awareness of how they arrived at a judgment, even a correct one. Two alternative models, the Unconsciousness hypothesis and the Inarticulation hypothesis are posited to describe the possible relationship between accuracy and awareness. Two studies are reported on the relationship between accuracy and awareness, both using the Interpersonal Perception Task (IPT). In the first study, the IPT was given to a sample of 476 undergraduates. Accuracy was measured by how many of the 30 IPT questions these judges answered correctly. Global awareness was indexed by having each judge guess how many of the 30 scenes they had answered correctly. In this coarse analysis, the accuracy-awareness relationship was positive but weak. A second experiment was conducted to produce more fine-grained tests of the accuracy-awareness relationship. Different versions of the IPT were presented to 134 undergraduates. Judges given each version of the IPT were asked to indicate their degree of confidence in each one of their answers. This second experiment found a positive, substantial relationship between accuracy and awareness, and this relationship was particularly strong when analyzed across experimental conditions as a whole. These findings support the Inarticulation hypothesis, and cast doubt on the Unconsciousness hypothesis. Implications for an emerging understanding of how nonverbal communication is processed are discussed.We wish to thank Robin Akert and Bob Rosenthal for helpful advice and inspiration.     

Content-masking methods as determinants of results of studies of nonverbal communication

The present study was designed to determine whether the technique used to control the semantic content of emotional communications might influence the results of research on the effects of gender, age, and particular affects on accuracy of decoding tone of voice. Male and female college and elementary school students decoded a 48-item audio tape-recording of emotional expressions encoded by two children and two college students. Six emotions — anger, fear, happiness, jealousy, pride and sadness — were expressed in two types of content-standard messages, namely letters of the alphabet and an affectively neutral sentence. The results of the study indicate that different methods for controlling content can indeed influence the results of studies of determinants of decoding performance. Overall, subjects demonstrated greater accuracy when decoding emotions expressed in the standard sentence than when decoding emotions embedded in letters of the alphabet. A technique by emotion interaction, however, revealed that this was especially true for the purer emotions of anger, fear, happiness and sadness. Subjects identified the less pure emotions of jealousy and pride relatively more accurately when these emotions were embedded in the alphabet technique. The implications of these results for research concerning the vocal communication of affect are briefly discussed.Preparation of this article was supported in part by the National Science Foundation.     

The motivational impairment effect in the communication of deception: Replications and extensions

Past research (e.g., DePaulo & Kirkendol, in press) has documented a motivational impairment effect in the communication of deception, whereby people who are more highly motivated to get away with their lies (relative to those who are less highly motivated) are less successful at doing so whenever observers can see or hear any of their nonverbal cues. In the present study, we report a conceptual replication of the effect: Subjects who told ingratiating lies under conditions in which they thought that the ability to convey particular impressions was an important skill (high competence-relevance) were less successful at getting away with those lies when judges could observe their nonverbal behaviors. We also report a conceptual replication of an unpredicted finding from an earlier study (DePaulo, Stone, & Lassiter, 1985b): Under the same conditions (ingratiating lies, high competence relevance), women were more likely to show the motivational impairment effect than were men. We predicted in this study that more attractive speakers would be less susceptible to the motivational impairment effect than less attractive speakers. Consistent with this prediction, under high motivational conditions (ingratiating lies, high competence-relevance), more attractive speakers were less likely to show the impairment than were less attractive speakers. Finally, we report suggestive evidence that the motivational impairment effect may occur when subjects are trying deliberately to control simultaneously all of their verbal and nonverbal behaviors.This research was supported by an NIMH research grant and an NIMH Research Scientist Award to the first author.

The Painful Truth: Interpretation of Facial Expressions of Pain in Older Adults

The purpose of this study was to determine whether it is more difficult to decode facial expressions of pain in older than in younger adults. The facial expressions of 10 younger and 10 older chronic pain patients undergoing a painful diagnostic test were viewed on videotape by untrained judges. Judges estimated the severity of pain being experienced by the patients. Ratings made of the older faces during painful moments described more pain, and appeared more accurate, than those made of younger faces. Judges also reported seeing more pain in posed, masked, and baseline facial expressions in the older adults. Age-related structural changes to the face were not responsible for this bias. This suggests that judges were predisposed to see pain in the faces of the older patients, and undermines the assumption that their ratings of pain in the painful moment segments were accurate.     

The effects of distance and individual differences in arousability on nonverbal involvement: A test of discrepancy-arousal theory

Mutual influence in human interaction refers to the tendency for persons to alter their verbal, vocal, and kinesic behaviors in response to the intensity, frequency or duration of those behaviors emitted by their partners. Numerous explanations of these processes have been put forward involving principles of approach-avoidance conflict, arousal, reward, and cognitive processes. These explanations are reviewed with special attention given to an arousal based theory, discrepancy-arousal. This theory holds that mutual influence is primarily the result of arousal changes due to the degree of discrepancy of partner's behavior from the receiver's expectation.The theory predicts that persons who differ in reaction to arousal should also differ in their response to a partner's immediacy. This hypothesis was tested on high and low sensation seekers under conditions of near and normal distances during an interview. Several different behavioral responses were coded, including eye gaze, posture and orientation, smiles and laughter, object- and body-focused gestures, vocalization, pauses, and latencies to respond. The hypothesized interaction did not materialize with a median split on sensation seeking. A measure of state-trait sensation seeking (STSS) was developed. The interaction between distance and a median split on the state-trait measure was significant for eye gaze and posture and orientation, with the high STSS subjects compensating less than the low STSS subjects.     

Nonverbal communication in clinical social work practice

The value of nonverbal cues in treating clients in reasserted, citing first the need for baseline data as well as an understanding of the context in which behavior occurs. The use of the various sensory channels to observe cues is introduced informally, followed by the three formal approaches to nonverbal data: proxemics, the study of distance and body orientation; kinesics, the study of body motion, posture, ect.; and paralinguistics, the study of the acoustical accompaniment of words. Skill in using nonverbal cues can enhance the therapeutic relationship, e.g., holding can be represented symbolically. A case illustration is presented where crying and weeping are explored in their multiple meanings; a family that used crying as a resistance in the initial stage of treatment was able to continue to cry, but in the service of mourning. It is concluded that the use of nonverbal analysis to break the code of communication with individual clients as well as larger groups is a necessary component of the therapist's approach.     

The effects of nonverbal synchrony on message comprehension and persuasiveness

Previous research has not considered the effects of nonverbal synchronization by a speaker on message processing and acceptance by a listener. In this experiment, 178 subjects watched one of three versions of a message—high synchrony, minimal synchrony or dissynchrony—presented by one of two speakers. Receivers of the high synchrony message, which employed kinesic cues synchronized to the vocal/verbal stream, showed higher recall of the message and were more persuaded by it than receivers of the dissynchronous message, which had kinesic cues out of sync with the vocal/verbal stream. Results on three other dependent measures—credibility, distraction and counterarguing—were mixed but were generally consistent with the credibility-yielding and distraction-yielding formulations outlined.     

Angle of regard: The effect of vertical viewing angle on the perception of facial expressions

Two studies were conducted using video records of real faces and three-dimensional schematic faces to investigate the perceptual distortions introduced by viewing faces at a vertical angle and their influence on the attribution of emotional expressions and attitudes. The results indicate that faces seen from below were perceived as morepositive and lessnegative, while faces seen from above appeared morenegative and lesspositive. This effect seems to be moderated by interindividual differences in facial morphology, and perhaps by differences in dynamic aspects of expressions. The second study investigated the respective contribution of the upper half and the lower half of the face to the perceptual distortion found. In general, judges based their attributions of emotional state more on cues from the upper half of the face.     

Age and Gender Differences in Decoding Basic and Non-basic Facial Expressions in Late Childhood and Early Adolescence

This study examined age and gender differences in decoding nonverbal cues in a school population of 606 (pre)adolescents (9–15 years). The focus was on differences in the perceived intensity of several emotions in both basic and non-basic facial expressions. Age differences were found in decoding low intensity and ambiguous faces, but not in basic expressions. Older adolescents indicated more negative meaning in these more subtle and complex facial cues. Girls attributed more anger to both basic and non-basic facial expressions and showed a general negative bias in decoding non-basic facial expressions compared to boys. Findings are interpreted in the light of the development of emotion regulation and the importance for developing relationships.
