Asymmetry of the face and facial expressions in relation to handedness
Hřebcová, Eliška ; Velemínská, Jana (advisor) ; Kožejová Jaklová, Lenka (referee)
Facial asymmetry is developed in every human and has an impact on everyone's life. Research of facial asymmetry is important not only in plastic surgery, aesthetic medicine and orthodontics, but also in forensic sciences, bioarchaeology and sociocultural anthropology. It can be influenced by various factors including the lateralization of cerebral hemispheres for cognitive and motor functions. According to the literature, handedness in humans is one of the most important forms of laterality which is probably related to facial asymmetry. The observed asymmetries differ not only between left-handers and right-handers, but also between men and women. Emotional expressions are also expressed asymmetrically on the face. Differences between positive and negative emotions as well as spontaneous and voluntarily expressions were observed. Different forms of laterality of motoric and cognitive cerebral functions are related to each other and their impact on facial asymmetry is therefore very complex.

Fluctuating asymmetry as a predictor of attractiveness of a human face
LAPEŠOVÁ, Tereza
This bachelor thesis deals with fluctuating asymmetry (FA) and its impact on the attractiveness of a human face. The aim of this bachelor thesis is to create a current overview on how FA affects perceived attractiveness of a human face. There are primarily explained evolutionary mechanisms related to the topic, followed by an overview of the general recourses of the partner choice among people in terms of evolutionary psychology, supplemented by an overview of specific researches and methods used in the research of attractiveness of FA in human faces.

Asymmetry of the human face
Korbelová, Tereza ; Velemínská, Jana (advisor) ; Hoffmannová, Eva (referee)
Facial asymmetry affects human life, especially in relationships with other people. Individuals with pathological asymmetries may have difficulty with integration into the collective, whether in childhood at school or later in adulthood at work. Presence and size of asymmetry reflects the potential quality of an individual's genes. Scientific research focused on measurement and evaluation of facial asymmetry provides valuable knowledge for various branches of medicine mainly for plastic surgery and orthodoncy, but also for forensic science, where it is used for personal identification. Asymmetries develop in the prenatal period and then they envolve and grow by the influence of external and internal factors during lifetime.
