The study of mimicry has a rich history of investigation in nonverbal communication research, although the area has struggled with inconsistent operationalizations of the construct. The Special Issue on Nonconscious Mimicry includes empirical, methodological and theoretical innovations, and provides guidance about future directions. This introduction highlights a number of emerging themes in this Special Issue, and places these themes in historical context. [ABSTRACT FROM AUTHOR]

When it comes to health(-risk) behaviors, researchers are apt to consider how to change behaviors from a top-down approach (i.e., using the conscious, reflective, deliberate system) even though much of human behavior is determined by bottom-up processes (i.e., the nonconscious, reflexive, impulsive system). Given that researchers have proposed that interventions that target nonconscious processes underlying health(-risk) behaviors may prove to be more effective than interventions that target conscious processes, we argue that understanding the ways in which mimicking and modeling affect health(-risk) behaviors is a critical—albeit largely unexplored—domain. In this paper, we review existing evidence that people mimic and model a broad range of health(-risk) behaviors: specifically, the cigarette smoking, alcohol drinking, (un)healthy eating, and physical activity of others. We then discuss the neural and psychological mechanisms underlying these effects. Next, we outline moderators: specifically, we discuss when mimicking and modeling are more likely to occur, who is more likely to mimic and model, as well as who is more likely to be mimicked and modeled. Finally, we consider how mimicry and modeling could be used to leverage healthy behavioral change. [ABSTRACT FROM AUTHOR]

This review explores spontaneous mimicry in the context of three questions. The first question concerns the role of spontaneous mimicry in processing conceptual information. The second question concerns the debate whether spontaneous mimicry is driven by simple associative processes or reflects higher-order processes such as goals, intentions, and social context. The third question addresses the implications of these debates for understanding atypical individuals and states. We review relevant literature and argue for a dynamic, context-sensitive role of spontaneous mimicry in social cognition and behavior. We highlight how the modulation of mimicry is often adaptive but also point out some cases of maladaptive modulations that impair an individuals' engagement in social life. [ABSTRACT FROM AUTHOR]

Observing nonverbal signals being directed toward unfamiliar individuals is known to influence attitudes and behavior toward those individuals. Specifically, observing biased nonverbal signals in favor of one individual over another can produce nonverbal signal-consistent attitudes among preschool children. Research has also shown that people have a tendency to mimic the behavior of others. The phenomenon of mimicking another's nonverbal emotional response and "catching" their emotions has long been established. However, it has yet to be examined whether this phenomenon is associated with attitude contagion. We hypothesized that preschool children who mimic the biased nonverbal signals of others will be more likely to adopt their social attitudes. Results of the current study indicated that as emotional mimicry became more frequent, children showed an increasingly greater probability of acquiring nonverbal signal-consistent attitudes. Moreover, the frequency of negative—but not positive—emotional mimicry was related to an increased probability of showing nonverbal signal-consistent attitudes. Our findings provide initial support for the notion that mimicking others' biased nonverbal signals may help facilitate attitude contagion. [ABSTRACT FROM AUTHOR]

The aim of the present study was to test the classic but under-researched hypothesis that individual differences in automatic emotional mimicry are positively related to individual differences in emotional contagion. To tap automatic mimicry and automatic emotional contagion, participants were exposed to affective stimuli with either a positive or negative valence (faces with a happy expression, n = 73; faces with a sad expression, n = 73) while their attention was directed toward nonaffective features of the stimuli. Emotional mimicry was measured with EMG (Corrugator, Zygomaticus). On average, in the sad emotional expression condition, participants' mood worsened, but the happy emotional expression condition did not evoke a general positive emotional contagion effect (across participants). Multigroup multilevel latent difference models revealed that in the sad emotional expression condition, individual differences in Corrugator activity were related to a larger increase in unpleasant mood, and in the happy emotional expression condition, individual differences in Zygomaticus activity were related to a larger decrease in unpleasant mood. That is, results of this study provided support for the mimicry-contagion link. [ABSTRACT FROM AUTHOR]

This article describes the basic mechanisms by which the nonverbal behavior of a communicator can influence recipients' attitudes and persuasion. We review the literature on classic variables related to persuasive sources (e.g., physical attractiveness, credibility, and power), as well as research on mimicry and facial expressions of emotion, and beyond. Using the elaboration likelihood model (ELM) as a framework, we argue that the overt behavior of source variables can affect attitude change by different psychological processes depending on different circumstances. Specifically, we describe the primary and secondary cognitive processes by which nonverbal behaviors of the source (e.g., smiling, nodding, eye contact, and body orientation) affect attitude change. Furthermore, we illustrate how considering the processes outlined by the ELM can help to predict when and why attractive, credible, and powerful communicators can not only increase persuasion but also be detrimental for persuasion.

How sensitive are we to mimicry in speech and gesture, and to what extent does observing mimicry affect our behavior? We addressed this question by asking whether participants who watched a video stimulus containing subtle instances of mimicry would adopt the mimicked features when describing the stimulus. Our participants watched one of four different video clips. The clips showed two people interacting, and contained varying degrees of verbal and gestural mimicry. Participants then described the stimulus, and their speech and gesture were analyzed. Participants who observed more mimicry reproduced more of the mimicked features in their descriptions—despite the fact that these cases of mimicry were quite subtle—indicating a high degree of sensitivity to mimicry.

Two experiments investigated the impact of group membership on non-conscious behavioral mimicry. Female participants viewed videotapes of female confederates who rubbed their faces whilst describing a picture. The extent to which the participant mimicked this face rubbing behavior was assessed from video footage taken using a hidden video-camera. Experiment 1 showed greater mimicry of a member of an in-group than of a member of an out-group. Experiment 2 showed both explicit and implicit liking of a target group to predict the extent of mimicry of a member of that group. There was a positive relationship between implicit liking and mimicry but a negative relationship between explicit liking and mimicry. Results are discussed in terms of processes underlying mimicry.

The articles in this special issue provide important, new insight into the evolutionary roots of expressive behavior. Across the three articles, a strong argument is made for behavioral mimicry, expressivity, and laughter providing adaptive value to ancestral humans that is still reflected in our modern world. The place of an evolutionary analysis in the development of a broader functional approach to nonverbal communication is described and discussed. Each article proposes specific dynamics through which expressive behaviors predispose receivers to respond in a manner benefitting the sender. The mediating mechanisms advanced in the articles are examined more closely and modifications in the proposed processes are considered. [ABSTRACT FROM AUTHOR]

The "chameleon effect" refers to the tendency to adopt the postures, gestures, and mannerisms of interaction partners (Chartrand & Bargh, 1999). This type of mimicry occurs outside of conscious awareness, and without any intent to mimic or imitate. Empirical evidence suggests a bi-directional relationship between nonconscious mimicry on the one hand, and liking, rapport, and affiliation on the other. That is, nonconscious mimicry creates affiliation, and affiliation can be expressed through nonconscious mimicry. We argue that mimicry played an important role in human evolution. Initially, mimicry may have had survival value by helping humans communicate. We propose that the purpose of mimicry has now evolved to serve a social function. Nonconscious behavioral mimicry increases affiliation, which serves to foster relationships with others. We review current research in light of this proposed framework and suggest future areas of research. [ABSTRACT FROM AUTHOR]

Presents information on a study that investigated the differences between individuals high and low in emotional empathy, as related to mimicry reactions at different levels of information processing. Basic assumptions and aims; Method of the study; Results of the study.

Lipps (1907) presented a model of empathy which had an important influence on later formulations. According to Lipps, individuals tend to mimic an interaction partner's behavior, and this nonverbal mimicry induces—via a feedback process—the corresponding affective state in the observer. The resulting shared affect is believed to foster the understanding of the observed person's self. The present study tested this model in the context of judgments of emotional facial expressions. The results confirm that individuals mimic emotional facial expressions, and that the decoding of facial expressions is accompanied by shared affect. However, no evidence that emotion recognition accuracy or shared affect are mediated by mimicry was found. Yet, voluntary mimicry was found to have some limited influence on observer' s assessment of the observed person's personality. The implications of these results with regard to Lipps' original hypothesis are discussed. [ABSTRACT FROM AUTHOR]
