Reliable facial muscle activation enhances recognizability and credibility of emotional expression

We tested Ekman's (2003) suggestion that movements of a small number of reliable facial muscles are particularly trustworthy cues to experienced emotion because they tend to be difficult to produce voluntarily. On the basis of theoretical predictions, we identified two subsets of facial action units (AUs): reliable AUs and versatile AUs. A survey on the controllability of facial AUs confirmed that reliable AUs indeed seem more difficult to control than versatile AUs, although the distinction between the two sets of AUs should be understood as a difference in degree of controllability rather than a discrete categorization. Professional actors enacted a series of emotional states using method acting techniques, and their facial expressions were rated by independent judges. The effect of the two subsets of AUs (reliable AUs and versatile AUs) on identification of the emotion conveyed, its perceived authenticity, and perceived intensity was investigated. Activation of the reliable AUs had a stronger effect than that of versatile AUs on the identification, perceived authenticity, and perceived intensity of the emotion expressed. We found little evidence, however, for specific links between individual AUs and particular emotion categories. We conclude that reliable AUs may indeed convey trustworthy information about emotional processes but that most of these AUs are likely to be shared by several emotions rather than providing information about specific emotions. This study also suggests that the issue of reliable facial muscles may generalize beyond the Duchenne smile.     

Assistive/rehabilitation technology, disability, and service delivery models

The United Nation's Millennium Development Goals do not explicitly articulate a focus on disability; similar failures in the past resulted in research, policy, and practice that are not generalizable and did not meet the needs of persons with disabilities since they were developed for an "average" population. Academics and professionals in health and other disciplines should have a knowledge base in evidence-based practices that improve well-being and participation of people with disabilities through effective service delivery of assistive technology. Grounded by a theoretical framework that incorporates a multivariate perspective of disability that is acknowledged in the convention on the rights of persons with disabilities and the World Health Organization's International Classification of Functioning, Disability and Health, we present a review of models of assistive technology service delivery and call for future syntheses of the fragmented evidence base that would permit a comparative effectiveness approach to evaluation.     

Attributions for ambiguity in a treatment-decision context can create ambiguity aversion or seeking

The phenomenon of ambiguity aversion suggests that people prefer options that offer precisely rather than imprecisely known chances of success. However, past work on people's responses to ambiguity in health treatment contexts found ambiguity seeking rather than aversion. The present work addressed whether such findings reflected a broad tendency for ambiguity seeking in health treatment contexts or whether specific attributions for ambiguity play a substantial role. In three studies, people choose between two treatment options that involved similar underlying probabilities, except that the probabilities for one option involved ambiguity. The attributions offered for the ambiguity played an important role in the results. For example, when the range of probabilities associated with an ambiguous treatment was attributed to the fact that different studies yield different results, participants tended to show ambiguity aversion or indifference. However, when the range was attributed to something that participants could control (e.g., regular application of a cream) or something about which they were overoptimistic (e.g., their immune system function), participants tended to show ambiguity seeking. Health professionals should be mindful of how people will interpret and use information about ambiguity when choosing among treatments.     

Validity Evidence for a Croatian Version of the Conditional Reasoning Test for Aggression

The Conditional Reasoning Test for Aggression (CRT‐A) is based on the idea that aggressive individuals use motive‐based cognitive biases to see their behavior as reasonable and that those biases can be measured with inductive reasoning tasks. Although the initial validation efforts for the CRT‐A in the United States have been reasonably successful, there has been no attempt to determine if the evidence of validity and reliability generalizes to other cultural contexts. In this paper, we describe four studies designed to systematically accumulate validity evidence for the CRT‐A using Croatian participants. Our analyses revealed that the Croatian adaptation of the CRT‐A yielded psychometric characteristics that were similar to those obtained on the US samples (Study 1). CRT‐A scores that predicted counterproductive work behaviors occurrence beyond self‐reported personality (Study 2) were independent from general mental ability as measured with an abstract reasoning test (Study 3), and not susceptible to faking (Study 4).     

An ethnographic study of issues surrounding the provision of sport opportunities to young men from a western Canadian inner-city

ObjectivesThe purpose of this study was to examine issues surrounding the provision of sport opportunities to young men from inner-city areas of Edmonton, Alberta, Canada. More specifically, the research question was: What are the benefits, constraints, and opportunities associated with providing sport programs to young men from inner-city areas?DesignEthnography.MethodsData were collected via 15 months of participant observation and interviews with 12 youth workers who were responsible for the provision of various sport programs to young inner-city dwellers. Analysis was framed around personal, social, and structural issues.ResultsAt a personal level sport provided young men with an outlet for overcoming boredom and a temporary reprieve from the conditions of their daily lives. At a social level sport provided opportunities for relationship building between the youth workers and the young men. However, enduring structural constraints associated with economic and social inequality and the lack of a coordinated approach to the delivery of services restricted the influence that sport could have in the lives of the young men.ConclusionThis study provided some precise understandings of the benefits, constraints, and opportunities associated with providing sport programs to members of specific populations in certain inner-city circumstances. Findings, therefore, have the potential to inform public health policy concerning the use of sport-for-development programming in such contexts.     

Facial expressions allow inference of both emotions and their components

Following Yik and Russell (1999) a judgement paradigm was used to examine to what extent differential accuracy of recognition of facial expressions allows evaluation of the well-foundedness of different theoretical views on emotional expression. Observers judged photos showing facial expressions of seven emotions on the basis of: (1) discrete emotion categories; (2) social message types; (3) appraisal results; or (4) action tendencies, and rated their confidence in making choices. Emotion categories and appraisals were judged significantly more accurately and confidently than messages or action tendencies. These results do not support claims of primacy for message or action tendency views of facial expression. Based on a componential model of emotion it is suggested that judges can infer components from categories and vice versa.     

Children's ability to control the facial expression of laughter and smiling: Knowledge and behaviour

A total of 64 children, aged 7 and 10, watched a clown performing three sketches rated as very funny by the children. Two experimental conditions were created by asking half of the participants to suppress their laughter. Facial expressions were videotaped and analysed with FACS. For both ages, the results show a significant shorter duration (but not a lower frequency) of episodes of laughter and Duchenne smiles, and greater frequency of facial control movements in the suppression compared to the free expression group. The detailed results on individual facial action units used to control amusement expressions suggest hypotheses on the nature of the underlying processes. The participants' explicit knowledge of their control strategies was assessed through standardised interviews. Although behavioural control strategies were reported equally frequently by the two age groups, 10-year-olds verbalised more mental control strategies than 7-year-olds. This theoretically expected difference was not related to the actual ability to control facial expression. This result challenges the commonly held assumption that explicit knowledge of control strategies results in a greater ability to execute such control in ongoing social interactions.     

Conscious emotional experience emerges as a function of multilevel, appraisal-driven response synchronization

In this paper we discuss the issue of the processes potentially underlying the emergence of emotional consciousness in the light of theoretical considerations and empirical evidence. First, we argue that componential emotion models, and specifically the Component Process Model (CPM), may be better able to account for the emergence of feelings than basic emotion or dimensional models. Second, we advance the hypothesis that consciousness of emotional reactions emerges when lower levels of processing are not sufficient to cope with the event and regulate the emotional process, particularly when the degree of synchronization between the components reaches a critical level and duration. Third, we review recent neuroscience evidence that bolsters our claim of the central importance of the synchronization of neuronal assemblies at different levels of processing.     

Behold the voice of wrath: cross-modal modulation of visual attention by anger prosody

Emotionally relevant stimuli are prioritized in human information processing. It has repeatedly been shown that selective spatial attention is modulated by the emotional content of a stimulus. Until now, studies investigating this phenomenon have only examined within-modality effects, most frequently using pictures of emotional stimuli to modulate visual attention. In this study, we used simultaneously presented utterances with emotional and neutral prosody as cues for a visually presented target in a cross-modal dot probe task. Response times towards targets were faster when they appeared at the location of the source of the emotional prosody. Our results show for the first time a cross-modal attentional modulation of visual attention by auditory affective prosody.
