Personality and the enactment of emotion

The meaning of personality traits for social interaction was investigated by exploring the personality correlates of abilities to pose emotions. This framework focuses on individual differences in socio-emotional skills. Thirty one males and 37 females were videotaped while attempting to communicate seven basic emotions nonverbally (i.e., using standard content communications), and sending success was measured by showing edited videotapes to judges. Hypothesized relationships between acting ability and scores on the Jackson Personality Research Form and the Eysenck Personality Inventory were then examined. The findings were seen to have implications for predicting individual strengths and weaknesses in social interaction as a function of certain personality traits and for understanding person perception.This research was supported in part by NIMH Grant #RO3MH31453 and Intramural Research Grants from UC Riverside to Howard Friedman, and indirectly by the Biomedical Research Support Program of NIH (#RR077010-11).

Accuracy of the judgment of facial expression of emotions as a function of sex and level of education

The purpose of this study is to examine the recognition of facial expressions of six emotions as a function of sex and level of education (high school, college, university) of the subjects. Three hundred French-speaking citizens of Quebec had to judge which emotion was expressed in various facial stimuli presented on slides. Results show that overall, the recognition of emotions was very good. However, there were significant and strong differences between emotions and sex and levels of education did not have strong effects on the results.This research was supported by grant EQ-1717 from Fonds FCAC (Gouvernment du Quebec).     

Does image size affect judgments of the face?

Whether the video-image of the face was larger than life or about one-fifth life size made no difference in observers' judgments of emotions, attitudes, and personality traits.This research was supported by a grant from NIMH, MH 11976.

Sex differences in nonverbal expressiveness: Emotional expression,personality, and impressions

Sex differences in expressiveness are well documented, but the reasons for and correlates of these important differences are not well studied. A comprehensive set of emotion-relevant personality measures was administered to 40 female and 39 male undergraduate participants, who were also videotaped in three situations: engaging in natural social interaction, describing a past emotional experience, and posing various emotions. Videotapes were judged by sets of naive observers as to emotion communicated and overall impression. Expressive females, who appeared friendly and dominant in social interaction, were found to have a hostile/aggressive personality (but this was not true of males). Expressive females also tended to look angry/disgusted when describing happy and sad experiences. The findings suggest that nonverbally skilled, charismatic women (but not men) may often possess a dominant/aggressive but self-controlled personality, in a new twist on the theory that sex differences in expressiveness result in part from the oppression of women in society.This research was supported in part by an intramural research grant from University of California, Riverside.     

The interrelationships of self-monitoring factors,personality traits,and nonverbal social skills

Following recent developments concerning individual differences in nonverbal social skills, the present study examined the inter-relationships of several standardized measures of nonverbal skills and personality. Particular attention was given to the concept of self-monitoring, thought to be a skill central to social interaction. Based on previous research which suggested that self-monitoring, as measured by the Self-Monitoring Scale (SMS), is a multidimensional construct, it was hypothesized that self-monitoring may actually be comprised of a number of more basic social skills. Correlations between standardized measures of basic social skills and three factors obtained from factor analysis of the SMS (Briggs, Cheek, & Buss, 1980) supported this conception. The elements of self-monitoring appear to be “charisma,” “performance,” and “social sensitivity.”     

Brief Report: Useful Information for Face Perception Is Described with FACS

When we perceive the emotions of other people, we extract much information from the face. The present experiment used FACS (Facial Action Coding System), which is an instrument that measures the magnitude of facial action from a neutral face to a changed, emotional face. Japanese undergraduates judged the emotion in pictures of 66 static Japanese male faces (11 static pictures for each of six basic expressions: happiness, surprise, fear, anger, sadness, and disgust), ranging from neutral faces to maximally expressed emotions. The stimuli had previously been scored with FACS and were presented in random order. A high correlation between the subjects' judgments of facial expressions and the FACS scores was found.     

Effects of alcohol on the nonverbal communication of anxiety: The impact of beliefs on nonverbal behavior

Three male and three female raters were shown videotapes of 29 male subjects who were speaking to a silent female confederate. Raters were asked to make 10 judgments about the subjects' behavior. The subjects had been assigned to one of two expectancy conditions in which they were led to believe the drink they consumed prior to meeting the confederate contained alcohol and tonic or tonic only. Actually, half of the subjects in each expectancy condition received alcohol and half received tonic only. Judgments of the female raters viewing the videotapes were congruent with physiological measures of the subjects' anxiety. Those subjects who believed they received alcohol were perceived by female raters as more relaxed, less anxious, less inhibited, and more dominant than subjects who believed they received tonic. The actual content of the drink had no significant effects on the raters' judgements of the subjects' behavior. Male raters were unable to discriminate among the experimental conditions. Implications for possible gender of rater effects in behavioral assessment procedures as well as for the impact of beliefs on nonverbal communication are discussed.     

Research Orientations and Sources of Influence: Agricultural Scientists in the U.S. Land‐Grant System*

Abstract This research builds on the work of Busch and Lacy, who have written extensively about the sources of influence on the choice of research problems in the agricultural sciences at land‐grant universities. Employing data from a 1995–1996 nationwide survey of land‐grant agricultural scientists, I use multiple regression techniques to investigate the relative importance of 19 sources of influence on agricultural scientists engaged in six research areas: productionist‐oriented, sustainable agriculture, environmental, basic, consumer‐oriented, and rural community‐oriented. The first objective of this paper is to revisit and assess many of Busch and Lacy's findings about the influences on land‐grant agricultural scientists. I find that different types of land‐grant research are influenced by distinct combinations of factors. The second major objective is to extend Busch and Lacy's work by spotlighting the significant influences on sustainable agriculture research. My multivariate findings show that this research appears to exhibit influences that reflect its dual productionist and environmental character.     

The role of social skills in encoding posed and spontaneous facial expressions

The purpose of this study was to determine the relationships between social skills and the abilities to express emotions intentionally and spontaneously. Students were videotaped during two tasks: a) while watching a series of emotionally arousing slides; and b) while posing emotional facial expressions. Judges viewing the videotapes determined how accurately the subjects could express emotions. Results suggested that certain social skills do underlie the ability to express emotions. Specifically, the ability to be emotionally expressive, but not ability to control emotions, is related to spontaneous sending ability. Expressive ability, coupled with role-playing skills, is related to posed sending ability. Additionally, the abilities to express emotions intentionally and spontaneously are positively related, suggesting that these two abilities involve some common, underlying social skill components.The authors would like to thank Charles Salinas for his assistance in the data collection.     

Preschool children's ability to identify and label emotions

The present study examined preschoolers' and adults' ability to identify and label the emotions of happiness, sadness, and anger when presented through either the face channel alone, the voice channel alone, or the face and voice channels together. Subjects were also asked to rate the intensity of the expression. The results revealed that children aged 3 to 5 years are able to accurately identify and label emotions of happy, sad, and angry regardless of channel presentation. Similar results were obtained for the adult group. While younger children (33 to 53 months of age) were equally accurate in identifying the three emotions, older children (54 to 68 months of age) and adults made more incorrect responses when identifying expressions of sadness. Intensity ratings also differed according to the age of the subject and the emotion being rated.Support for this research was from a grant by the National Science Foundation (#BNS8317229) to Nathan A. Fox. The research was also supported by a grant awarded to Nathan Fox from the National Institutes of Health (#R01MH/HD17899). The authors would like to thank Professor A.

A cross-cultural comparison of impressions created by age-related variations in gait

Cross-cultural similarities and differences in impressions of age-related gait qualities were investigated. Specifically, Korean subjects' perceptions of the age, sex, and traits of 5 to 70 year old American men and women, whose gaits were depicted in point-light displays, were compared with American subjects' perceptions documented by Montepare and Zebrowitz-McArthur (1988). Substantial cross-cultural agreement was found for perceptions of the walkers' age and sex. Moreover, with walkers' perceived age and sex controlled, both American and Korean ratings of the walkers' strength and happiness showed a linear decrease with age, and ratings of their sexiness showed a curvilinear relationship to age. Whereas American ratings of dominance showed a linear decrease with walkers' age, no such relationship was observed for Korean ratings. The findings supported both the ecological theory of social perception and an interactionist model of cross-cultural perception, which suggest that some reactions to gait information are universal while others are determined by culturally specific values which may influence the movements of younger and older individuals and the meanings perceivers associate with these movements.This research was supported in part by BRSG S07 RR07044 awarded by the Brandeis Research Support Grant Program, Division of Research Resources, NIH.

Cohabitation before marriage

This study compares 159 married couples who had or had not lived together previous to marriage with respect to a number of demographic and personality variables. There were few differences between the two groups on background variables but many on personality traits. Males who had cohabited perceived themselves as more androgynous, attractive, and less religious than males who did not cohabit. Females who cohabited saw themselves as more interested in art, attractive, extroverted, intelligent, liberal, androgynous, and having more leadership qualities; while being less religious, clothes-conscious, and law-abiding than women who did not cohabit. Couples who cohabited showed significantly greater sexual experimentation and self-perception accuracy than the couples who did not cohabit. Cohabitors revealed some background and trait within-group differences as a function of the length of their cohabital experiences. The majority of differences between the groups were in terms of variables assessed on the females. Theoretical implications of these findings are discussed.

Accuracy of nonverbal communication as determinant of interpersonal expectancy effects

The person perception paradigm was used to address the effects of experimenters' ability to encode nonverbal cues and subjects' ability to decode nonverbal cues on magnitude of expectancy effects. Greater expectancy effects were obtained when experimenters were better encoders and subjects were better decoders of nonverbal cues and the separate contributions of experimenter's and subject's nonverbal skills were of similar magnitudes.The authors wish to express their thanks to Rena Baskin for her help.Preparation of this article and the research described was facilitated by a grant [GS-3942] from the Division of Social Sciences of the National Science Foundation to Robert Rosenthal.     

Moving Beyond Basic Emotions in Aging Research

There is consistent evidence that older adults have difficulties in perceiving emotions. However, emotion perception measures to date have focused on one particular type of assessment: using standard photographs of facial expressions posing six basic emotions. We argue that it is important in future research to explore adult age differences in understanding more complex, social and blended emotions. Using stimuli which are dynamic records of the emotions expressed by people of all ages, and the use of genuine rather than posed emotions, would also improve the ecological validity of future research into age differences in emotion perception. Important questions remain about possible links between difficulties in perceiving emotional signals and the implications that this has for the everyday interpersonal functioning of older adults.     

A New Test to Measure Emotion Recognition Ability: Matsumoto and Ekman's Japanese and Caucasian Brief Affect Recognition Test (JACBART)

In this article, we report the development of a new test designed to measure individual differences in emotion recognition ability (ERA), five studies examining the reliability and validity of the scores produced using this test, and the first evidence for a correlation between ERA measured by a standardized test and personality. Utilizing Matsumoto and Ekman's (1988) Japanese and Caucasian Facial Expressions of Emotion (JACFEE) and Neutral Faces (JACNeuF), we call this measure the Japanese and Caucasian Brief Affect Recognition Test (JACBART). The JACBART improves on previous measures of ERA by (1) using expressions that have substantial validity and reliability data associated with them, (2) including posers of two visibly different races (3) balanced across seven universal emotions (4) with equal distribution of poser race and sex across emotions (5) in a format that eliminates afterimages associated with fast exposures. Scores derived using the JACBART are reliable, and three studies demonstrated a correlation between ERA and the personality constructs of Openness and Conscientiousness, while one study reports a correlation with Extraversion and Neuroticism.     

Influences on parental involvement of African American adolescent fathers

This study explores several factors related to the parental involvement of African-American adolescent fathers. These factors are identified through empirical literature as exerting influence upon adolescent fathers and their roles as fathers. An exploratory research design was utilized in order to obtain a better understanding of these fathers and how the identified factors affected parental involvement. Findings suggest that these adolescent fathers exhibit a level of parental involvement that is not generally perceived by the public. Additionally, the findings suggest that the identified factors interact to influence different dimensions of parental involvement.This research study was supported with a grant from the Maurice Falk Medical Foundation in Pittsburgh, PA.

Urea to creatinine ratio: a forgotten marker of poor nutritional state in patients undergoing hemodialysis treatment

Abstract

Background: Malnutrition is common in subjects undergoing hemodialysis and is associated with increased morbidity and mortality. Studies investigating factors associated with malnutrition and effect of various interventions to treat these patients are needed. We aimed to screen older and young patients undergoing chronic hemodialysis, for malnutrition, and seek its association with clinical factors including anxiety and depression and laboratory variables including urea/creatinine ratio (UCR).

Methods: Duration of hemodialysis treatment, medications taken, anthropometric measurements and routine laboratory results were recorded. Mini nutritional assessment and Beck anxiety and Beck depression inventories were applied. Study variables between subjects with malnutrition, malnutrition risk and normal nutritional states were compared. Older and younger patients were also compared regarding malnutrition and laboratory results. Linear regression analysis was performed to seek independent factors associated with malnutrition score.

Results: Clinical and laboratory data except for UCR were found to be similar among young and older patients. UCR increased, while albumin, body mass index and weight circumference decreased along with worse nutritional state. Low albumin level, body mass index and UCR and higher hemoglobin level and depression score were independent factors associated with malnutrition.

Conclusion: In addition to routinely used markers of malnutrition UCR may provide additional information regarding malnutrition in this population.     

An analysis of the encoding and decoding of spontaneous and posed smiles: The use of facial electromyography

Twenty subjects judged 80 video segments containing brief episodes of smiling behavior for expression intensity and happiness of the stimulus person. The video records were produced under instructions to (a) pose, (b) experience a happy feeling or (c) to both experience and show a happy feeling. An analysis of the integrated facial electromyogram (EMG), recorded over four muscle regions (zygomaticus major, depressor anguli oris, corrugator supercilii, andmasseter), showed that judgments of happiness and of intensity of expression could be predicted in a multiple regression analysis (multipleR = .64 for perceived happiness and .79 for perceived expression intensity). The perception of happiness was affected by EMG activity in regions other thanzygomaticus major. The use of parameters other than the mean of the integrated EMG, namely variance, skewness, kurtosis and properties of the amplitude distributions across time, provided accurate classification of the elicitation conditions (pose happiness versus experience happiness) in a discriminant analysis. For the discrimination of posed and felt smiles variables describing aspects of facial activity in the temporal domain were more useful than any of the other measures. It is suggested that facial EMG can be a useful tool in the analysis of both the encoding and decoding of expressive behavior. The results indicate the advantage of using multiple-site EMG recordings as well as of using amplitude and temporal characteristics of the facial EMG measures.The research was supported in part by funds associated with the John Sloan Dickey Third Century Professorship (Kleck) and in part by grant BNS-8507600 from the National Science Foundation (Lanzetta).

Emotional and behavioral problems of Asian American adolescents: A comparative study

Social, academic, emotional functioning and social support of 99 ninth-grade Asian American students were investigated using standardized measures. When compared to 404 ninth-grade Caucasian adolescents who had attended the same school, Asian American students exhibited less delinquent behavior and performed better academically. However, they were significantly more isolated, more depressed and anxious, less apt to be involved in after school activities or seek help for their problems, and internalized their social problems. Also, they had fewer role models and less social support, underscoring the psychosocial and emotional plight of Asian American adolescents and the dire need to establish proactive outreach programs.This work was supported by NIMH grant #MH41569-07.
