Movement Differences between Deliberate and Spontaneous Facial Expressions: Zygomaticus Major Action in Smiling

Previous research suggests differences in lip movement between deliberate and spontaneous facial expressions. We investigated within participant differences between deliberately posed and spontaneously occurring smiles during a directed facial action task. Using automated facial image analysis, we quantified lip corner movement during periods of visible Zygomaticus major activity. Onset and offset speed, amplitude of movement, and offset duration were greater in deliberate smiles. In contrast to previous results, however, lip corner movement asymmetry was not greater in deliberate smiles. Observed characteristics of deliberate and spontaneous smiling may be related to differences in the typical context and purpose of the facial signal. Karen L. Schmidt, Zara Ambadar, Jeffrey F.

Facial Mimicry of Spontaneous and Deliberate Duchenne and Non-Duchenne Smiles

Increasing evidence suggests that Duchenne (D) smiles may not only occur as a sign of spontaneous enjoyment, but can also be deliberately posed. The aim of this paper was to investigate whether people mimic spontaneous and deliberate D and non-D smiles to a similar extent. Facial EMG responses were recorded while participants viewed short video-clips of each smile category which they had to judge with respect to valence, arousal, and genuineness. In line with previous research, valence and arousal ratings varied significantly as a function of smile type and elicitation condition. However, differences in facial reactions occurred only for smile type (i.e., D and non-D smiles). The findings have important implications for questions relating to the role of facial mimicry in expression understanding and suggest that mimicry may be essential in discriminating among various meanings of smiles.     

A Cross-species Comparison of Facial Morphology and Movement in Humans and Chimpanzees Using the Facial Action Coding System (FACS)

A comparative perspective has remained central to the study of human facial expressions since Darwin’s [(1872/1998). The expression of the emotions in man and animals (3rd ed.). New York: Oxford University Press] insightful observations on the presence and significance of cross-species continuities and species-unique phenomena. However, cross-species comparisons are often difficult to draw due to methodological limitations. We report the application of a common methodology, the Facial Action Coding System (FACS) to examine facial movement across two species of hominoids, namely humans and chimpanzees. FACS [Ekman & Friesen (1978). Facial action coding system. CA: Consulting Psychology Press] has been employed to identify the repertoire of human facial movements. We demonstrate that FACS can be applied to other species, but highlight that any modifications must be based on both underlying anatomy and detailed observational analysis of movements. Here we describe the ChimpFACS and use it to compare the repertoire of facial movement in chimpanzees and humans. While the underlying mimetic musculature shows minimal differences, important differences in facial morphology impact upon the identification and detection of related surface appearance changes across these two species.

Over-emoting and perceptions of sincerity: Effects of nuanced displays of emotions and chosen words on credibility perceptions during a crisis

This study focuses on understanding how words and discrete facial emotions influence credibility perceptions of both prepared statements and spontaneous question and answer sessions. We build on and extend existing theoretical work concerning crises communication and discrete emotions. Using a press conference simulation, spokesperson video recordings were analyzed using automated face-emotion recognition software (FaceReader™) to characterize discrete emotions. A crisis-message-strategy trained dictionary for Linguistic Inquiry and Word Count (LIWC) was used to characterize message content. Our results indicate that spokespeople can control their verbal messages better in prepared statements than in more spontaneous settings, but their facial emotions are quite similar in both settings. Only three discrete emotions are related to credibility perceptions: anger, sadness, and surprise, but sadness and surprise are not universally viewed positively or negatively. Expressing too much emotion, or over-emoting, is problematic. Expressing more anger in the Q&A, which we refer to as reactive anger, is perceived negatively, and when spokespeople emote a low amount of sadness and use a high amount of words expressing sincerity they are viewed as having the most credible messages.     

Are There Affordances of Suggestibility in Facial Appearance?

Physical personality involves perceptible aspects of human appearance (both morphological and expressive) that are reliable cues about human traits and dispositions. Inferences made about personality on the basis of perceiving the cues in appearance may be valid as well as invalid. While the perception of many of such characteristics has been studied before, perception of suggestibility from facial appearance has remained unexplored. Here we present the results of a study where we show that real suggestibility does not correlate with perceived suggestibility. However, there is a significant correlation between perceived suggestibility and some facial characteristics such as babyfacedness and merriness.     

Effects of Dynamic Attributes of Smiles in Human and Synthetic Faces: A Simulated Job Interview Setting

We examined the effects of the temporal quality of smile displays on impressions and decisions made in a simulated job interview. We also investigated whether similar judgments were made in response to synthetic (Study 1) and human facial stimuli (Study 2). Participants viewed short video excerpts of female interviewees exhibiting dynamic authentic smiles, dynamic fake smiles, or neutral expressions, and rated them with respect to a number of attributes. In both studies, perceivers’ judgments and employment decisions were significantly shaped by the temporal quality of smiles, with dynamic authentic smiles generally leading to more favorable job, person, and expression ratings than dynamic fake smiles or neutral expressions. Furthermore, authentically smiling interviewees were judged to be more suitable and were more likely to be short-listed and selected for the job. The findings show a high degree of correspondence in the effects created by synthetic and human facial stimuli, suggesting that temporal features of smiles similarly influence perceivers’ judgments and decisions across the two types of stimulus.

Patterns of Gaze Between Parents and Children in European American and Mexican American Families

Mutual gaze has been shown to be a valuable channel of nonverbal communication. To examine mutual gaze between parents and children, 43 European American (EA) and 57 Mexican American (MA) families were coded on the occurrence of talking and gaze during a brief discussion. MA families showed lower levels of father-to-child gaze, mother-to-son gaze, and child-to-father gaze than EA families. MA families also showed less father–child mutual gaze, as well as less mother–child gaze for sons than EA families. Child gaze aversion was more common in European American families. Levels of gaze, father–child mutual gaze, and child gaze aversion all were positively correlated with acculturation. The importance of research exploring possible differences in function and meaning of gaze across cultural groups is emphasized.

The Effects of Social Interaction and Personal Relationships on Facial Expressions

Previous studies have reported that the expression of smiles is facilitated by social interaction between partners. We examined the effects of social interaction and personal relationships on facial expressions in Japan. Pairs of friends and strangers seated next to each other (the no partition condition) or separated by a partition (the partition condition) were shown film clips aimed to elicit either positive or negative affect. Smiles were facilitated in the no partition condition in which participants interacted with each other. Further, the effect of social interaction on frowns differed depending on whether pairs were friends or strangers.     

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.

Explicit Use of Categorical and Dimensional Strategies to Decode Facial Expressions of Emotion

This experiment compares the explicit use of categorical and dimensional decoding strategies to recognize facially expressed emotion. Results suggest that people can consciously employ both strategies but that their facility in doing so is a function of the particular emotion displayed in combination with the completeness of the expression. By identifying the relative effectiveness of deliberate use of particular decoding strategies in specific circumstances, this investigation has implications for the design of facial decoding studies, for further research into cognitive mechanisms underlying the recognition of facially expressed emotion, and for development of practical applications to enhance facility with facial decoding.

Perception of Emotions in the Hand Movement Quality of Finnish Sign Language

This study investigated whether people can decode emotion (happiness, neutrality, and anger) communicated via hand movements in Finnish sign language when these emotions are expressed in semantically neutral sentences. Twenty volunteer participants without any knowledge of sign language took part in the experiment. The results indicated that the subjects were able to reliably decode anger and neutrality from the quality of hand movements. For happy hand expressions, the responses of happiness and neutrality were confused. Thus, the study showed that emotion-related information can be encoded in the quality of hand movements during signing and that this information can be decoded without previous experience with this particular mode of communication.     

The Occupy Movement and the Politics of Vulnerability

The Occupy movement has generated a significant amount of scholarly literature, most of which has focused on the movement's tactics or goals, or sought to explain its emergence. Nevertheless, we lack an explanation for the movement's broad appeal and mass support. In this article we present original research on Occupy in New York City, Detroit, and Berlin, which demonstrates that the movement's heterogeneous participants coalesced around the concept of vulnerability. Vulnerability is an inability to adapt to shocks and stresses, and it inhibits social reproduction and prohibits social mobility. Rather than specifically discussing the wealth of elites per se, Occupy participants consistently expressed the feeling that the current political economic system safeguards elites and increases the vulnerability of everyone else. We argue that the Occupy movement has reworked the relationship among a range of political struggles that were hitherto disconnected (i.e. ‘old’ and ‘new’ social movements) and rendered them complementary through the politics of vulnerability.     

The residents’ ‘images of the past’ in the architecture of Salt City, Jordan

In the preservation movement, the perception of older buildings by the residents of a city has received limited consideration. This paper reports on empirical research conducted in a small traditional city, Salt, Jordan. It examines ‘images of the past’ within a model of nonverbal communication of the meaning in the built environment. The objective of this study is to identify similarities among residents’ images of the past. A survey research design using multiple sorting techniques with open-ended questions was used to identify residents’ images of the past. These images were elicited through the observation of coloured photographs of a sample of older buildings from the city centre. Images of the past were examined within three content areas: knowledge of the past, date of construction of the building, and character of the past of Salt City. Findings suggest that older buildings in the centre of the city do evoke similar images of the past for residents, regardless of their length of residential tenure. From these similar images, a common image of the past focus on public or social use buildings along with residential buildings of the settlement era. Residents has associated these buildings with the past functions and development of the city. This study presents an approach for operationalizing the image of the past as a research variable (in terms of the scale of a city and of different cultures).     

Polanyi's Double Movement and Neoliberalization in Korea and Japan

This paper reformulates and extends Polanyi's main insights in The Great Transformations (2001 [1944]) and attempts to theorize the societal countermovement against neoliberalism by illustrating the cases of Korea and Japan. Polanyi's main approach was to synthesize three critical domains: the state, market, and society, and his notion of double movement should be understood as such. Predicated on his double movement, I analytically decompose the mechanism of societal countermovement, emphasizing the importance of social organizations that aggregate people's insecurities and translate them into a political voice capable of acquiring social protection. Applying this analytical framework of the double movement to Korea and Japan reveals that the problem with the conventional understanding of the double movement is that it necessarily arrives at social compensation equilibrium. This paper implies that a highly contentious society, like Korea's, and a highly docile society, like Japan's, may both hinder social welfare provision.     

Temporal Aspects of Facial Displays in Person and Expression Perception: The Effects of Smile Dynamics,Head-tilt,and Gender

Recent work suggests that temporal aspects of facial displays influence the perception of the perceived authenticity of a smile. In the present research, the impact of temporal aspects of smiles on person and expression perception was explored in combination with head-tilt and gender. One hundred participants were shown different types of smiles (slow versus fast onset) in combination with three forms of head-tilt (none, left, or right) exhibited by six computer-generated male and female encoders. The encoders were rated for perceived attractiveness, trustworthiness, dominance, and the smiles were rated for flirtatiousness and authenticity. Slow onset smiles led to more positive evaluations of the encoder and the smiles. Judgments were also significantly influenced by head-tilt and participant and encoder gender, demonstrating the combined effect of all three variables on expression and person perception.

Children's Expression of Emotional Meaning in Music Through Expressive Body Movement

Recent research has demonstrated that preschool children can decode emotional meaning in expressive body movement; however, to date, no research has considered preschool children's ability to encode emotional meaning in this media. The current study investigated 4- (N = 23) and 5- (N = 24) year-old children's ability to encode the emotional meaning of an accompanying music segment by moving a teddy bear using previously modeled expressive movements to indicate one of four target emotions (happiness, sadness, anger, or fear). Adult judges visually categorized the silent videotaped expressive movement performances by children of both ages with greater than chance level accuracy. In addition, accuracy in categorizing the emotion being expressed varied as a function of age of child and emotion. A subsequent cue analysis revealed that children as young as 4 years old were systematically varying their expressive movements with respect to force, rotation, shifts in movement pattern, tempo, and upward movement in the process of emotional communication. The theoretical significance of such encoding ability is discussed with respect to children's nonverbal skills and the communication of emotion.     

Anna Hazare's Anti-Corruption Movement and the Limits of Mass Mobilization in India

A hunger strike that played upon Gandhi's legacy of civil disobedience and mass protest was India's capstone event for 2011. Initiated by Anna Hazare, a 74-year-old self-styled Gandhian, the protest targeted the government's new anti-corruption legislation, which Hazare proclaimed as too weak. Hazare's demand for a strong anti-corruption law, leading to the establishment of an independent ombudsman (Lokpal), had slowly gained momentum in the first half of 2011, when Hazare collected a sizeable following. It was his unexpected arrest on the eve of the August protest, however, that thrust him into the limelight, sparking candle-lit marches across the country and swelling the ranks of his movement, Indian Against Corruption (IAC). Hazare was hailed as a leader of Gandhian proportions and applauded for his humble origins, numerous awards, and ecologically conscious development work in Ralegan Siddhi, where Hazare took up residence in 1975, following a brief career in the army. His movement, which appeared to be climbing from strength to strength, was thought to be a major political force of lasting influence. But in the year since the Ramlila protest, Hazare's movement has lost steam, with key leaders oscillating between calling for a stronger movement based on ‘the people's guidance’ and entertaining the possibility of entering electoral politics through the formation of a new political party. This article investigates the reasons for the deceleration of the Hazare movement, with an emphasis on why Hazare failed to win the support of the liberal and left sections of society, particularly the intelligentsia.     

Framing Faith: Explaining Cooperation and Conflict in the US Conservative Christian Political Movement

Despite the burgeoning literature on coalition work, very little is known about the cooperative potential within social movements. Drawing on archival, interview, and secondary data, we examine cooperation and conflict in the US conservative Christian political movement from 1970 to 1994. We highlight how framing, political elites and intramovement dynamics within the conservative Christian political movement altered the cooperative potential over time. Specifically, we find that the conservative Christian political movement initially had a strong coordinative potential and even engaged in organization building as a way to formalize cross-denominational cooperation. However, as the evangelical wing of the movement sought to build and consolidate its political power, it began to frame issues in ways that reflected a particularized world view regarding the role of the state in fostering a moral society. Other conservative Christian organizations responded by couching their understanding of political issues in their own faith traditions, creating divisions within the movement and ultimately making cooperation impossible. Conceptually, this research broadens how we think about cooperation and points to the importance of specialization and political elites to cooperation within movements.     

Social media and Umbrella Movement: insurgent public sphere in formation

The study examines the role of social media during the Umbrella Movement in Hong Kong that lasted from September to December 2014. By interviewing a random sample of 1011 respondents over the telephone before the end of the Umbrella Movement, it was found that social media had become an insurgent public sphere (IPS) in the protest movement. Data showed that acquisition of political news through social media was related positively to support for the Umbrella Movement and adversely with satisfaction and trust of established political authorities, including the Hong Kong Special Administrative Region government, the Hong Kong police, and the Chinese central government. The insurgent public sphere role of social media, its implications, and likely development vis-à-vis the state and the market are discussed.
