“…Ekman & Friesen reasoned that deliberately made facial expressions, such as false smiles, would require more cortical involvement and thereby be more likely to show asymmetry because of cerebral specialization than uncontrolled, spontaneous, felt emotional expressions. The early work by Lynn & Lynn (1938, 1943 on facial asymmetries supports the finding that asymmetries are rare for spontaneous smiles. Ekman, Hager, & Friesen (1981) verified this difference in symmetry.…”

Malingering occupies a range on a continuum from biased self-perception to conscious, deliberate, serious lies. One aspect of this continuum is the element of self-conscious or deliberate control. Suggestions from Darwin's writings concerning the role of voluntary and involuntary activation of the facial muscles are examined and illustrated with data from a 40 year program of research on deception. The impact of the voluntary-involuntary distinction on the appearance, timing, symmetry and cohesion of facial expressions of emotion is explained. Data relevant to changes in vocal and gestural aspects of demeanor in honest and deceptive behavior are also reviewed. The relevance of these laboratory-based findings on the voluntary control of nonverbal behavior in assessing some types of malingering is discussed.

“…Thus, the right hemiface of a familiar face could be perceived as showing more emotion, even though the left hemiface might in fact be exhibiting a greater degree of movement relative to some neutral baseline expression (Borod et al, 1983). The use of direct measurement to assess asymmetries in the expressiveness of the two sides of the face assumes that there is a causal connection between amount of muscle movement and degree of expressiveness (Borod et al, 1983;Ekman et al, 1981;Lynn & Lynn, 1938, 1943. However, the type of movement may be as important as the amount, and the effect of both may be modified by other factors such as how familiar the face is (as suggested by the present results), how genuine the expression looks, or even how asymmetric the face is.…”

Two experiments were carried out to determine whether configural information about the left-right organization of a face is represented in memory. In Experiment 1, subjects consistently chose normal (correct) photographs as better likenesses of familiar faces than mirror-reversed photographs. This effect was stronger for more familiar faces, and did not depend on the presence of asymmetric hairstyles or single, asymmetrically located features (e.g., moles, warts). In Experiment 2, subjects were asked to decide which ofthe left and right composite faces was a better likeness of the person. The left composite is normally considered a better likeness in perceptual matching tasks where the normal photograph is present. Left composites were regarded as better likenesses than right composites, despite the fact that this bias appeared to compete with one in favor of the more realistic of the two composites. The results of Experiments 1 and 2 suggest that configural information about the left-right organization of faces is represented in memory. The right hemiface of a familiarface was considered more expressive than the left hemiface. This is opposite to the normal result for unfamiliar faces. The implications of the results for models of face representations and for future research directions are discussed.Despite the similarity of faces as visual patterns, we are able to discriminate between and remember many faces for long periods of time (Bahrick, Bahrick, & Wittlinger, 1975). Bahrick et al. showed that people could recognize pictures of classmates at a 90% correct performance level, independent of class size, for up to 35 years after graduation. Our ability to remember faces, often over an extended period of time, may be essentially unlimited under natural conditions of learning with repeated, long duration exposures to a face. Even a single, brief exposure may be sufficient to encode a face in memory. Faces signal identity and emotional state, both of which are important predictors of behavior. Therefore, there has probably been strong selection pressure for the ability to encode faces quickly and to remember them for long periods of time.Our capacity for encoding and remembering faces is not yet understood, and theories of facial representation are not well developed. Past research has emphasized the importance of individual features, such as the eyes, nose, and mouth, for discriminating between and remembering faces. Changing these features impairs discrimination and recognition performance (for a comprehensive review,

“…They also indicated that the results in relation to negative emotions were similar but the results could not be generalized because the numbers of data were small. As with most other studies, Lynn and Lynn argued that there was also no difference in asymmetry between the two sides of the face [40,41].…”

Facial Feature Movements Caused by Various Emotions: Differences According to Sex

Facial muscle micro movements for eight emotions were induced via visual and auditory stimuli and were verified according to sex. Thirty-one main facial features were chosen from the Kinect API out of 121 initially obtained facial features; the average change of pixel value was measured after image alignment. The proposed method is advantageous as it allows for comparisons. Facial micro-expressions are analyzed in real time using 31 facial feature points. The amount of micro-expressions for the various emotion stimuli was comparatively analyzed for differences according to sex. Men's facial movements were similar for each emotion, whereas women's facial movements were different for each emotion. The six feature positions were significantly different according to sex; in particular, the inner eyebrow of the right eye had a confidence level of p < 0.01. Consequently, discriminative power showed that men's ability to separate one emotion from the others was lower compared to women's ability in terms of facial expression, despite men's average movements being higher compared to women's. Additionally, the asymmetric phenomena around the left eye region of women appeared more strongly in cases of positive emotions.
