The Intensity of Emotional Facial Expressions and Decoding Accuracy

The influence of the physical intensity of emotional facial expressions on perceived intensity and emotion category decoding accuracy was assessed for expressions of anger, disgust, sadness, and happiness. The facial expressions of two men and two women posing each of the four emotions were used as stimuli. Six different levels of intensity of expression were created for each pose using a graphics morphing program. Twelve men and 12 women rated each of the 96 stimuli for perceived intensity of the underlying emotion and for the qualitative nature of the emotion expressed. The results revealed that perceived intensity varied linearly with the manipulated physical intensity of the expression. Emotion category decoding accuracy varied largely linearly with the manipulated physical intensity of the expression for expressions of anger, disgust, and sadness. For the happiness expressions only, the findings were consistent with a categorical judgment process. Sex of encoder produced significant effects for both dependent measures. These effects remained even after possible gender differences in encoding were controlled for, suggesting a perceptual bias on the part of the decoders.     

How Fast are the Leaked Facial Expressions: The Duration of Micro-Expressions

Micro-expression has gained a lot of attention because of its potential applications (e.g., transportation security) and theoretical implications (e.g., expression of emotions). However, the duration of micro-expression, which is considered as the most important characteristic, has not been firmly established. The present study provides evidence to define the duration of micro-expression by collecting and analyzing the fast facial expressions which are the leakage of genuine emotions. Participants were asked to neutralize their faces while watching emotional video episodes. Among the more than 1,000 elicited facial expressions, 109 leaked fast expressions (less than 500 ms) were selected and analyzed. The distribution curves of total duration and onset duration for the micro-expressions were presented. Based on the distribution and estimation, it seems suitable to define micro-expression by its total duration less than 500 ms or its onset duration less than 260 ms. These findings may facilitate further studies of micro-expressions in the future.     

Late Life Gambling: The Attitudes and Behaviors of Older Adults

For a significant number of retired older adults (aged 65+), gambling has become a new form of recreation and entertainment. While prevalence studies have examined the incidence of problem gambling in other age groups, little research attention has been paid to the impact of gambling on older adults since the increase in availability and accessibility of legalized gambling within the last ten years. This study investigated the prevalence of problem gambling behaviors (SOGS-R), depression (GDS-15), levels of life satisfaction (SWLS), and motivations for gambling among older adults. A total of 315 older adults completed the study questionnaire and were grouped and analyzed according to those sampled from gambling venues and those from within the community. Results of the study found the most frequent accession and spending on several types of gambling occurred among older adults who were sampled at gambling venues. Older adults who were sampled at gambling venues were also found more likely to have higher levels of disordered gambling than older adults from the community, as measured by the SOGS-R. Relaxation, boredom, passing time, and getting away for the day were also the most likely reported motivations for the older adults who were gamblingpatrons. These findings provide an initial profile of older adults and their attitudes, motivations and gambling behaviors.     

Judging Facial Emotion Expressions in Context: The Influence of Culture and Self-Construal Orientation

We assessed the impact of social context on the judgment of emotional facial expressions as a function of self-construal and decoding rules. German and Greek participants rated spontaneous emotional faces shown either alone or surrounded by other faces with congruent or incongruent facial expressions. Greek participants were higher in interdependence than German participants. In line with cultural decoding rules, Greek participants rated anger expressions less intensely and sad and disgust expressions more intensely. Social context affected the ratings by both groups in different ways. In the more interdependent culture (Greece) participants perceived anger least intensely when the group showed neutral expressions, whereas sadness expressions were rated as most intense in the absence of social context. In the independent culture (Germany) a group context (others expressing anger or happiness) additionally amplified the perception of angry and happy expressions. In line with the notion that these effects are mediated by more holistic processing linked to higher interdependence, this difference disappeared when we controlled for interdependence on the individual level. The findings confirm the usefulness of considering both country level and individual level factors when studying cultural differences.     

The Use of Humor With Older Adults Aging in Place

As more older adults seek ways to remain in their homes during their “golden years,” humor has proven to be a worthwhile intervention that reduces stress and provides a hopeful, playful, and optimistic environment. Development of creative and supportive housing situations for older adults combined with the use of modern technology (e.g., the Internet and computer devices used in the home), aid in bringing humor to the older adult. This article addresses some of the challenges that older adults face and the way that the use of humor can assist them to meet these challenges.     

Multiple Messages: Facial Recognition Advantage for Compound Expressions

The impact of singular (e.g. sadness alone) and compound (e.g. sadness and anger together) facial expressions on individuals' recognition of faces was investigated. In three studies, a face recognition paradigm was used as a measure of the proficiency with which participants processed compound and singular facial expressions. For both positive and negative facial expressions, participants displayed greater proficiency in processing compound expressions relative to singular expressions. Specifically, the accuracy with which faces displaying compound expressions were recognized was significantly higher than the accuracy with which faces displaying singular expressions were recognized. Possible explanations involving the familiarity, distinctiveness, and salience of the facial expressions are discussed.     

On Specifying Specificity: Facial Expressions at 4 Months

Izard (2004/this issue) clarifies the position of differential emotions theory by proposing a distinction between hard and soft versions of event‐emotion expression relations. We concur that the best design to examine situational specificity in facial expressions is one that utilizes multiple stimulus situations assessed over multiple occasions and ages. However, the problem of how to identify, a priori, a family of stimulus situations remains. We offer an example from our own recent work demonstrating how facial expressions and physiological indexes may converge to indicate the presence of a meaningful family of stimulus situations. Specifically, we found evidence for a family of frustrating, goal‐blocking events that elicited expressions and cortisol responses indicative of anger at 4 months. Yet, individual differences exist in that these situations also elicited expressions and cortisol changes indicative of sadness. Identification of a more comprehensive set of such situations throughout infancy will allow researchers to more systematically examine the degree to which situational specificity of emotions is present.     

Evaluation of Verbal Behavior in Older Adults

Approximately 5% of older adults have a dementia diagnosis, and language deterioration is commonly associated with this disorder (Kempler, 2005). Several instruments have been developed to diagnose dementia and assess language capabilities of elderly adults. However, none of these instruments take a functional approach to language assessment as described by Skinner (1957). The purpose of this study was to develop and evaluate a function-based assessment for language deficits of older adults. Thirty-one participants were categorized into a control group (n  =  15) and a dementia group (n  =  16) based on their score on the Dementia Rating Scale-2. Individuals with dementia performed significantly worse on the tact assessment than those without dementia. Participants from both groups performed better on measures of tacts than intraverbals or mands, even though topographically identical responses were required in these assessments. The data provide support for Skinner''s conceptualization of functionally independent verbal operants.     

Anxiety and Depression: Implications for Older Adults

By the year 2030, it is projected that one in every three Americans will be 55-years-old or older. This age group is by far thefastest growing segment of the population. With the growing number of older adults, the importance of understanding aging and common disorders of laterlife is essential. In particular, anxiety anddepression are among the most common problems in older adults. However, differentiating anxiety and depression at the mood, symptom, and syndromal levels has been a long-standing problem in psychopathology research. In addition to a growing need for research, clinicians will also need to take an active role in the development and implementation of treatment as the population of older adults increases. In particular, mental health service providers must become informed about the economic implications for older adults as the structure of health insurance continues to change.

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.     

Categorical Representation of Facial Expressions in the Infant Brain

Categorical perception, demonstrated as reduced discrimination of within‐category relative to between‐category differences in stimuli, has been found in a variety of perceptual domains in adults. To examine the development of categorical perception in the domain of facial expression processing, we used behavioral and event‐related potential (ERP) methods to assess discrimination of within‐category (happy‐happy) and between‐category (happy‐sad) differences in facial expressions in 7‐month‐old infants. Data from a visual paired‐comparison test and recordings of attention‐sensitive ERPs showed no discrimination of facial expressions in the within‐category condition, whereas reliable discrimination was observed in the between‐category condition. The results also showed that face‐sensitive ERPs over occipital‐temporal scalp (P400) were attenuated in the within‐category condition relative to the between‐category condition, suggesting a potential neural basis for the reduced within‐category sensitivity. Together, these results suggest that the neural systems underlying categorical representation of facial expressions emerge during the early stages of postnatal development, before acquisition of language.     

The Role of the Environment in Sedentary Behavior in Community-Dwelling Older Adults

To compare amounts of sedentary behavior and physical activity in adults residing in planned group residential settings to those residing in private homes, this study recruited 31 older adults who resided in planned group residential settings (n = 13) and in private homes (n = 18). Daily activities were measured using the SenseWear Armband for 7 days. Estimates of the duration of daily activities performed across sedentary, light, and moderate-to-vigorous intensities were captured. It was found that participants in planned group residential settings were older (age 85.9 ± 3.5 vs. 78.3 ± 7.2; p = 0.001) and spent more time in sedentary behaviors (12.7 ± 1.5 vs. 11.3 ± 1.6; p = 0.02) than participants in private homes. The difference was attenuated slightly after controlling for age and wear time (adjusted difference 1.2 ± 0.6 hours, p = 0.06). Thus, adults residing in planned group residential settings, which provide supportive services, were more sedentary than adults residing in private homes. The environment in which older adults live may contribute to sedentary behavior.     

Distress in Emerging Adults: Further Evaluation of the Painful Feelings About Divorce Scale

Young adults from divorced families experience clear emotional distress despite most not meeting diagnostic criteria for emotional disorders. Laumann-Billings and Emery (2000) developed the Painful Feelings About Divorce (PFAD) scale to assess the emotional distress emerging adults feel regarding childhood parental divorce. The study sample is undergraduates predominately between the ages of 18 and 22. This study adds to the literature by (a) further demonstrating the PFAD scale reliability and validity, (b) including participants with both divorced and separated but never married parents, and (c) assessing generalizability of the PFAD with a more diverse socioeconomic sample.     

FACSGen: A Tool to Synthesize Emotional Facial Expressions Through Systematic Manipulation of Facial Action Units

To investigate the perception of emotional facial expressions, researchers rely on shared sets of photos or videos, most often generated by actor portrayals. The drawback of such standardized material is a lack of flexibility and controllability, as it does not allow the systematic parametric manipulation of specific features of facial expressions on the one hand, and of more general properties of the facial identity (age, ethnicity, gender) on the other. To remedy this problem, we developed FACSGen: a novel tool that allows the creation of realistic synthetic 3D facial stimuli, both static and dynamic, based on the Facial Action Coding System. FACSGen provides researchers with total control over facial action units, and corresponding informational cues in 3D synthetic faces. We present four studies validating both the software and the general methodology of systematically generating controlled facial expression patterns for stimulus presentation.     

Cross-Cultural Judgments of Spontaneous Facial Expressions of Emotion

We report data concerning cross-cultural judgments of emotion in spontaneously produced facial expressions. Americans, Japanese, British, and International Students in the US reliably attributed emotions to the expressions of Olympic judo athletes at the end of a match for a medal, and at two times during the subsequent medal ceremonies. There were some observer culture differences in absolute attribution agreement rates, but high cross-cultural agreement in differences in attribution rates across expressions (relative agreement rates). Moreover, we operationalized signal clarity and demonstrated that it was associated with agreement rates similarly in all cultures. Finally, we obtained judgments of won-lost match outcomes and medal finish, and demonstrated that the emotion judgments were associated with accuracy in judgments of outcomes. These findings demonstrated that members of different cultures reliably judge spontaneously expressed emotions, and that across observer cultures, lower absolute agreement rates are related to noise produced by non-emotional facial behaviors. Also, the findings suggested that observers of different cultures utilize the same facial cues when judging emotions, and that the signal value of facial expressions is similar across cultures.     

Mimicry and the Judgment of Emotional Facial Expressions

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.     

Recognition of Facial Expressions of Negative Emotions in Romantic Relationships

Previous research has demonstrated that individuals who were accurate at recognizing facial expressions of emotions reported better relationships with family and friends. The purpose of the present study was to test whether the ability to recognize facial expressions of negative emotions predicted greater relationship satisfaction with their romantic relationships and whether this link was mediated by constructive responses to conflict. Participants currently involved in a romantic relationship completed a validated performance measure of recognition of facial expressions and afterwards reported on the responses they engaged in during conflict with their romantic partner and rated their romantic relationship satisfaction. Results showed that accurate recognition of facial expressions of negative emotions (anger, contempt, disgust, fear, and sadness) predicted less conflict engaging behaviors during conflict with their romantic partners (but not positive problem solving and withdrawal), which in turn predicted greater relationship satisfaction. The present study is the first to show that the ability to recognize facial expressions of negative emotions is related to romantic relationship satisfaction and that constructive responses to conflict such as less conflict engaging behaviors, mediate this process.
