For example, the most common feature of the anger face is the lowered brow. In summary, to date there is little doubt regarding the fact that emotional facial expressions can be recognized across cultures. For more than a century, scientists have wondered whether all humans experience the same basic range of emotions—and if they do, whether they express them in the same way. As predicted, participants were slower to identify dominant faces embedded in angry expressions and affiliative faces embedded in happy expressions than vice versa. Second, the challenge posed by the more ambiguous expressions that most people show in most situations has not been adequately addressed. The facial morphology of women and younger individuals, for example, appears to enhance the cues associated with happiness, whereas those of men and older individuals enhance the cues associated with anger Becker et al. Beliefs about the emotionality of others 6.

For all pairwise comparisons p -values were sidak corrected for multiple comparisons. GMO labeling makes public more likely to trust food companies Jun. Certain relatively static facial features are strongly associated with dominance and affiliation. Emotional expression modulates perceived gaze direction. First, participants see the same expression on several faces and their success in recognition is averaged across these exemplars and second, the expressions that are used are intense to a degree rarely encountered in everyday life. Electromyography recordings were recorded from the corrugator supercilii, zygomaticus major, and orbicularis oculi muscles during passive observation of static and dynamic images of happiness and anger.
FACIAL EXPRESSIONS | Anger
Participants judged the gaze of angry, fearful and neutral faces across a range of gaze directions. View Article Google Scholar 5. Similar to previous studies, neither static [ 28 ] nor dynamic [ 29 ] angry facial expressions evoked any significant response in the EMG activity of the CS. Conversely, the postauricular reflex was potentiated preferentially for female happiness expressions. Signals were rectified, integrated with a moving average filter integrating over 50 ms, resampled to 1 kHz, and tested for artefact.
Further studies are needed to evaluate the role of dynamic emotional expression in the facial mimicry in both sexes as well as with regard to stimulus sex. Our results concerning happiness agree with those of previous EMG studies, in which passive observation of happy facial expressions elicited an expected pattern of ZM and CS muscle activity interpretable as facial mimicry [ 39 , 40 ]. EMG activity of muscles related to happiness during happy video clips predicted increased prosocial behaviour i. These studies also showed that an angry expression is not an automatic reaction. Determining the width of this cone provides a potentially more sensitive measure of perceptual differences than those used in previous studies Lobmaier et al. Sex differences in emotion: Stimuli used in the experimental procedure were a subset of recordings of a larger sample of facial expressions created for a purpose of a different project and as such were not published.
