Almost all work in automatic facial expression analysis has focused on recognition of prototypic expressions rather than dynamic changes appearance over time. To investigate the relative contribution features to recognition, we used feature tracking measure relation between amplitude and duration smile onsets spontaneous deliberate smiles 81 young adults Euro- African-American background. Spontaneous were smaller had a larger more consistent smiles. A linear discriminant classifier using...

This study examined the influence of individualism-collectivism on communication in ingroup and outgroup relationships. Differences were predicted collectivistic cultures. It was also hypothesized that self-monitoring predicted-outcome value (POV) relationships affect processes these Data collected Hong Kong Japan (collectivistic) Australia United States (individualistic). Results supported prediction regarding cultural variability communication, as well those POV.

The face can communicate varied personal information including subjective emotion, communicative intent, and cognitive appraisal. Accurate interpretation by observer or computer interface depends on attention to dynamic properties of the expression, context, knowledge what is normative for a given individual. In two separate studies, we investigated individual differences in base rate positive facial expression specific action units over intervals from 4 12 months. Facial was measured using...

Effective conceptualizations of research burden should address indirect burdens related to duration, intensity, and invasiveness. Introducing the concept perceived burden, we developed, tested, validated a new instrument, Perceived Research Burden Assessment (PeRBA). Initial psychometric evaluation PeRBA reveals good internal consistency, evidence face validity, acceptable convergent discriminant validity.

Although the importance of facial expression in human computer interaction and normal is widely acknowledged, there very little data on normative characteristics stable individual differences for even most common expressions. Dynamic 195 spontaneous smiles from 95 individuals were measured using action coding system, automated analysis electromyography. Normative patterns observed included characteristic timing other actions with respect to unit 12 (“smile”) a mean duration 15.7 frames smile...

The purpose of this essay is to overview the study language and ethnic identity. general role in social categorisation influence categorisations on attitudes, as well specific identity microsociolinguistic, macrosociolinguistic, psychological aspects use, sociolinguistic stereotypes, ethnolinguistic vitality, speech accommodation are reviewed. contributions present volume also outlined context these areas research.

The importance of the face in social interaction and intelligence is widely recognized anthropology. Yet adaptive functions human facial expression remain largely unknown. An evolutionary model as behavioral adaptation can be constructed, given current knowledge phenotypic variation, ecological contexts, fitness consequences behavior. Studies are available, but results not typically framed an perspective. This review identifies relevant physical phenomena integrates study this behavior with...

Both the configuration of facial features and timing actions are important to emotion communication. Previous literature has focused on former. We developed an automatic expression analysis system that quantifies as well head eye motion during spontaneous expression. To assess coherence among these modalities, we recorded analyzed smiles in 62 young women varied ethnicity ranging age from 18 35 years. Spontaneous occurred following directed action tasks, a situation likely elicit...

This study was undertaken to address the issue of data reporting in psychiatric sector New York City Medicaid, largest publicly financed health care delivery system nation. Six outpatient clinics general hospitals, four with residency programs, and all 29 free standing were audited as charts from 120 psychiatrists billing for 10 or more Medicaid patients. Overall agreement chart diagnoses 91% psychiatrists, 79% free-standing clinics, 77% hospital clinics. Agreement varied by diagnosis. Bias...

Facial attractiveness is associated with a variety of positive social characteristics including trustworthiness. Variations in smiling, such as the appearance Duchenne marker and increased intensity expression, have likewise been linked judgments The study investigated interaction effects models' their smiling on impressions perceived Participants rated expressivity neutral, low intensity, high images 45 women models. These were also presented to second group participants who Repeated...

The purpose of this study was to evaluate the ability Automated Facial Image Analysis (AFA) detect changes in facial motion after Botox injections patients with nerve disorders accompanied by abnormal muscle activity. Eight subjects received for oral ocular synkinesis (n = 6), 1), and/or depressor anguli oris overactivity 3). Subjects were video-recorded during 2 directed action tasks before and treatment. AFA measurement Grading System (FGS) scores used effects Botox. After Botox, detected...

We investigate the effect of quantified statistical facial asymmetry as a biometric under expression variations. Our findings show that measures (AsymFaces) are computationally feasible, containing discriminative information and providing synergy when combined with Fisherface Eigen-face methods on image data two publically available face databases (Cohn-Kanade (T. Kanade et al., 1999) Feret (P.J. Phillips 1998)).

The purpose of this study was to demonstrate the range emotional expressions that can be displayed by nurse and family caregiver during a telehospice videophone consultation. We hypothesized providing care via would gain access rich nonverbal signals from communicate her own social presence caregiver, potentially enhance building empathy between caregiver.Videorecording case exemplar contact obtained using Beamer, commercially available product allows display both caller receiver on an...

What is the function of emotional tearing? Previous work has found a tear effect, which resolves ambiguity in neutral expressions and increases perceptions sadness sad expressions. Tearing, however, associated with variety states, it remains unclear how effect generalizes to other emotion Here we expand upon previous works by examining ratings video clips depicting posed facial presented without tears. We replicate Provine et al.'s (2009) findings that tearing Furthermore, find specific...

The major purpose of this study was to examine the influence cultural variability on communication. It predicted that in individualism‐collectivism influences uncertainty reduction ingroup and outgroup relationships, while masculinity‐femininity same‐ opposite‐sex relationships. also hypothesized self‐monitoring outcome value relationships processes these Data were collected from respondents Japan (a collectivistic masculine culture) United States (an individualistic feminine culture)....

Asymmetric facial expression is generally attributed to asymmetry in movement, but structural the face may also affect of expression. Asymmetry posed expressions was measured using image-based approaches digitised sequences 55 individuals, N=16 men, N=39 women. Structural (at neutral expression) higher men than women and accounted for .54, .62, .66 variance at peak joy, anger, disgust expressions, respectively. Movement (measured by change pixel values over time) found, unrelated joy or...
