چکیده

-Are there consistent differences between the emotions attributed to the right and left hemiface? Six studies investigated this old question, using a new technique of computerized image reconstruction that eliminates several confounding factors common in previous studies. Findings suggest that there are no consistent differences between the emotions and personality attributed to the right and the left hemiface. Nevertheless, when the two hemifaces were simultaneously compared on intensity, the left hemiface showed greater intensity in posed smiles. As a whole, the present study suggests the possibility of a slight inference of brain laterality in posed expressions, but not in resting faces.

Asymmetry of the face in orthodontic patients.

OBJECTIVE To investigate the laterality of the normal asymmetry of the human face, examining differences in laterality in relation to sex, growth stage, and skeletal classification. MATERIALS AND METHODS A total of 1800 Japanese subjects (651 males and 1149 females; mean age, 15 years 3 months; range, 4 years 2 months to 59 years 11 months) were selected. Individuals in the sample were catego...

Facial hair whorls (trichoglyphs) and the incidence of motor laterality in the horse.

Several species demonstrate obvious motor laterality (sidedness, handedness) in their motor function. Motor laterality in the horse affects locomotion and subsequently equine performance during training and may have inherent safety implications for equitation. Some of the most commonly used identification features in the horse are hair whorls (trichoglyphs), since their specific location and ch...

Laterality of Facial Expressions of Emotion: Universal and Culture-Specific Influences

Recent research indicates that (a) the perception and expression of facial emotion are lateralized to a great extent in the right hemisphere, and, (b) whereas facial expressions of emotion embody universal signals, culture-specific learning moderates the expression and interpretation of these emotions. In the present article, we review the literature on laterality and universality, and propose ...

The role of structural facial asymmetry in asymmetry of peak facial expressions.

Asymmetric facial expression is generally attributed to asymmetry in movement, but structural asymmetry in the face may also affect asymmetry of expression. Asymmetry in posed expressions was measured using image-based approaches in digitised sequences of facial expression in 55 individuals, N=16 men, N=39 women. Structural asymmetry (at neutral expression) was higher in men than women and acco...

Prevalence of facial asymmetry in Tirupati population: A posteroanterior cephalometric and photographic study

AIMS AND OBJECTIVE The human face is the most prominent aspect in human social interactions, and therefore, it seems reasonable opting for orthodontic treatment is to overcome psychosocial difficulties relating to facial and dental appearance and enhance the quality of life in doing so. MATERIALS AND METHODS Posteroanterior cephalograms and frontal photographs of 100 participants (50 males an...

Cerebral lateralisation for facial processing: gender-related cognitive styles determined using Fourier analysis of mean cerebral blood flow velocity in the middle cerebral arteries.

Facial processing was studied in 16 (eight men and eight women) right-handed healthy participants using a new functional transcranial Doppler technique called functional transcranial Doppler spectroscopy (fTCDS). MFV was recorded simultaneously in both right and left middle cerebral arteries in dark condition and during visual processing of object and facial tasks. fTCDS used Fourier analysis o...
