50 male and 50 female participants' facial electromyographic (EMG) activity at the left corrugator and zygomatic muscle regions and self-reports of emotions were recorded while they were viewing Pleasant and Unpleasant photographs. Analysis showed that the ratio of EMG power between the periods of photograph viewing and baseline at the zygomatic muscle region was significantly higher than that at the corrugator muscle region while viewing Pleasant photographs and that the EMG ratio at the… Expand

Sex Differences in Affective Facial Reactions Are Present in Childhood
TLDR
It is demonstrated that sex differences in the somatic component of affective motor patterns are present also in childhood, with boys showing less ample EMG responses than age-matched girls. Expand
Can you read my pokerface? A study on sex differences in dentophobia
TLDR
Female phobic women showed enhanced disgust-related facial electromyographic activity to dental treatment scenes relative to men, which points to the greater relevance of disgust for the female symptomatology of dentophobia, or it might also be possible that male patients more successfully inhibit disgust reactions during confrontation. Expand
Subtypes of anhedonia and facial electromyography response to negative affective pictures in non-psychiatric adults
TLDR
The relationship between anhedonia and flat affect varied as a function of sex and anhedonian subtype, and may help explain discrepancies in the sparse existing literature examining this relationship in psychiatric populations. Expand
Diminished emotion expressivity but not experience in men and women with schizophrenia.
TLDR
Men and women with schizophrenia did not significantly differ from one another in the frequency of facial expressions, but both groups exhibited fewer expressions than women without schizophrenia. Expand
The effects of appearance and motion of virtual characters on emotional reactivity
TLDR
Both the appearance and the motion of the virtual characters significantly affected participants’ emotional valence in a dynamic pattern and emotional intensity, with reactions to subjectively aversive and/ or active stimuli as more negative than reactions to neutral and/or passive stimuli. Expand
Identifying a subset of fear-evoking pictures from the IAPS on the basis of dimensional and categorical ratings for a German sample.
TLDR
Sex differences for categorical and dimensional ratings were found for a considerable number of IAPS pictures, as well as differences from the US norms, underscore the necessity of using country-specific and sex-specific norms when selecting stimuli. Expand
Feeling Stressed and Ugly? Leave the City and Visit Nature! An Experiment on Self- and Other-Perceived Stress and Attractiveness Levels
TLDR
It is shown that the rather stressful experience of a short-term urban walk mirrors in the face of men and is detectable by women. Expand
Playing a rigged game: inequality’s effect on acute stress responses
PLAYING A RIGGED GAME: INEQUALITY’S EFFECT ON ACUTE STRESS RESPONSES Income and wealth inequality have been consistently increasing around the world. High inequality corresponds with high rates ofExpand
The Emotional Contagion Scale: Factor Structure and Psychometric Properties in a Portuguese Sample
TLDR
The Portuguese version of the Emotional Contagion Scale also had good internal consistency and test-retest reliabilities; thus it is a psychometrically sound measure within a Portuguese population. Expand

Effects of Viewing Pleasant and Unpleasant Photographs on Facial EMG Asymmetry
TLDR
It was concluded that the intensity of facial EMG activity on the left side of the face was stronger than the right side ofThe face during the process of emotional expression. Expand
Facial muscle patterning and subjective experience during affective imagery: sex differences.
TLDR
Facial electromyographic activity was recorded from the zygomatic, corrugator, masse-ter and frontalis muscle regions in 30 male and 30 female subjects to indicate the importance of evaluating gender in psychophysiological studies of emotion. Expand
Imagined Events with Specific Emotional Valence Produce Specific Patterns of Facial EMG Activity
TLDR
It was concluded that the negative self-generated emotions were associated with increased EMG activity of corrugator muscles and positive self-acting emotions with increased EMT activity of zygomatic muscles. Expand
Electromyographic activity over facial muscle regions can differentiate the valence and intensity of affective reactions.
TLDR
It is suggested that gradients of EMG activity over the muscles of facial expression can provide objective and continuous probes of affective processes that are too subtle or fleeting to evoke expressions observable under normal conditions of social interaction. Expand
Study of Posed Emotion in Facial EMG Asymmetry
TLDR
37 subjects' facial electromyographic activity at the corrugator and zygomatic muscle regions were recorded while they were posing with happy and sad facial expressions, indicating that the power of facial EMG activity on the left side of the face was stronger than on the right side ofThe face while posing both happy andSad expressions. Expand
Gender differences in facial reactions to facial expressions
TLDR
The results showed that angry faces evoked increased corrugator activity whereas happy faces evokes increased zygomatic activity, which is consistent with previous findings indicating that females are more facially reactive than are males. Expand
The psychophysiology of disgust: differentiating negative emotional contexts with facial EMG.
  • S. Vrana

  • 1993
TLDR
Heart rate acceleration was greater during disgust, anger, and joy imagery than during pleasant imagery, and the expressive physiology of disgust was occasioned by the action set of active avoidance or rejection of sensory stimulation. Expand
Looking at pictures: affective, facial, visceral, and behavioral reactions.
TLDR
Responsibility specificity, particularly facial expressiveness, supported the view that specific affects have unique patterns of reactivity, and consistency of the dimensional relationships between evaluative judgments and physiological response emphasizes that emotion is fundamentally organized by these motivational parameters. Expand
Gender Differences in Facial Reactions to Fear-Relevant Stimuli
The aim of the present study was to explore whether females are specifically more facially reactive than males, or whether females are more emotionally reactive in general, as reflected even byExpand
Facial reactions to happy and angry facial expressions: evidence for right hemisphere dominance.
TLDR
It is concluded that the present results support the hypothesis that the right brain hemisphere is predominantly involved in the control of spontaneously evoked emotional reactions. Expand
