Visual attention to faces in intersexual and intrasexual selection
Pátková, Žaneta ; Třebická Fialová, Jitka (advisor) ; Lukavský, Jiří (referee) ; Stirratt, Michael (referee)
This thesis focuses on visual attention towards faces in intersexual and intrasexual selection. It consists of two main parts. The first part begins with a brief overview of the intersexual and intrasexual selection mechanisms. Within the framework of intersexual selection, facial attractiveness is discussed, with its putative link to health and immune system function. Within the framework of intrasexual selection, the thesis focuses on perceived facial dominance and formidability and their connection to actual characteristics. Moreover, specific facial traits and morphological features connected with judgements of attractiveness, dominance, and formidability are described. Given the scarce evidence of direct visual attention towards facial features connected with judgements of facial attractiveness and dominance or formidability, we discuss the eye-tracking method, which can measure direct visual attention. A brief summary of eye-tracking studies focusing on visual attention to faces, especially during attractiveness and dominance assessments, is provided. Finally, the thesis focuses on how individual sensory modalities (visual, olfactory and vocal) relate to each other in the perception of individuals and the detection of cues to an individual's quality. The second part of this thesis includes...

Facial attractiveness and skin color and texture
Kolingerová, Agáta ; Pátková, Žaneta (advisor) ; Pokorný, Šimon (referee)
The main aim of this thesis is, in the form of a literature review and critical evaluation, to summarize the available findings from scientific research on the influence of skin color and texture on facial attractiveness. The first part briefly introduces some of the evolutionary perspectives on attractiveness and then the aspects primarily studied in the past that affect facial attractiveness, i.e., symmetry, averageness and sexually dimorphic features. The main section of this thesis is devoted to other important traits affecting facial attractiveness, that is, skin color and texture. Topics discussed include individual skin color traits (i.e., redness, yellowness, lightness and homogeneity of color), while this thesis tries to describe their association with actual health or physical condition. The influence of culture and gender on the perception of these traits is also included. Regarding skin texture, the topics of acne, scars, radiance and wrinkles and their effect on perceived attractiveness are discussed. Similarly to color traits, potential influences of culture and gender are also presented. Keywords attractiveness, color, texture, skin, perception, health
