40 subjects' facial electromyographic (EMG) activity at the corrugator and zygomatic muscle regions were recorded while they were viewing pleasant and unpleasant photographs. Analysis showed that the EMG activity at the left zygomatic muscle region generated the highest power, followed by the right zygomatic, left corrugator, and right corrugator muscle regions, while viewing pleasant photographs. The EMG activity at the left corrugator muscle region generated the highest power, followed by the… Expand

Sex Differences Found in Facial EMG Activity Provoked by Viewing Pleasant and Unpleasant Photographs
Analysis showed that compared to men, women reported relatively higher feelings of pleasantness and generated significantly higher EMG ratios at the zygomatic muscle region while viewing Pleasant photographs and women reported significantly less feelings ofpleasantness and generate significantly lower EMG ratio at the corrugator muscle region While viewing Unpleasant photographs.

Study of Posed Emotion in Facial EMG Asymmetry
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.

Simultaneous recording of EEG and facial muscle reactions during spontaneous emotional mimicry
The combined EEG-EMG results suggest that early visual processing of face expression may determine the magnitude of subsequent facial imitation, with dissociable effects for P1 and N170. Expand

The effect of stimulus valence and arousal on facial electromyographic (EMG) asymmetry was investigated to inform the debate about two contrasting hypotheses of emotion: the right hemisphereExpand
Undifferentiated facial electromyography responses to dynamic, audio-visual emotion displays in individuals with autism spectrum disorders.
Evidence that fEMG responses in ASD are undifferentiated with respect to the valence of the stimulus is discussed in light of potential underlying neurobiological mechanisms. Expand
Effects of viewing affective pictures on sEMG activity of masticatory and postural muscles
The results show that emotional inputs seems not influence the activity of masticatory and postural muscles, recorded by sEMG. Expand

The present study investigated the effects of facial EMG changes in mean instantaneous mean frequency (IMNF) captured over corrugator supercilii and zygomaticus major for differentiating core affects, and indicated that low valence/high arousal affective state can be discriminated by corrugators from neutralvalence/low arousal.

Asymmetry of Facial Expressions of Emotion
The purpose of this chapter is to review the various theories of facial emotion lateralization and to provide an examination of the research conducted to date that addresses these theories, drawingExpand
Single Trial Evoked Potentials Study during an Emotional Processing Based on Wavelet Transform
The results indicated the effectiveness of the wavelet transform-based approach in ERP single-trial extraction and further supported the view that emotional stimuli are processed more intensely. Expand

Laterlized facial muscle response to positive and negative emotional stimuli.
The results are consistent with the hypothesized specialization of the left and right cerebral hemispheres for the mediation of positive and negative emotions, respectively. Expand
Facial muscle patterning and subjective experience during affective imagery: sex differences.
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
Age-Invariance in the Asymmetry of Stimulus-Evoked Emotional Facial Muscle Activity
This study examined possible effects of aging on the lateralization of stimulus-evoked emotional facial muscle activity. Older participants (mean age 68.4 years) and younger participants (mean ageExpand
Electromyographic activity over facial muscle regions can differentiate the valence and intensity of affective reactions.
Physiological measures have traditionally been viewed in social psychology as useful only in assessing general arousal and therefore as incapable of distinguishing between positive and negativeExpand
Electromyographic activity over facial muscle regions can differentiate the valence and intensity of affective reactions.
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
Facial reactions to happy and angry facial expressions: evidence for right hemisphere dominance.
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
Specific forms of facial EMG response index emotions during an interview: from Darwin to the continuous flow hypothesis affect-laden information processing.
Facial electromyographic and audiovisual recordings were obtained while individuals were interviewed about themselves and individuals were asked to describe what they had been thinking of during specific segments of the interview marked by distinctive electromyography responses over the brow region in the context of ongoing but stable levels of activity elsewhere in the face.

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
The facial muscle patterning of posed and imagery-induced expressions of emotion by expressive and nonexpressive posers
Much research on emotional facial expression employs posed expressions and expressive subjects. To test the generalizability of this research to more spontaneous expressions of both expressive andExpand
Effects of positive and negative affect on electromyographic activity over zygomaticus major and corrugator supercilii.
Results revealed a stronger linear effect of valence on activity over corrugator supercilii versus zygomaticus major, and positive and negative affect ratings indicated that positive andnegative affect have reciprocal effects on activityover corrugators, but not zyg automaticus major. Expand
