Approach of Evolutionary Psychology to Research of Human Sexuality and Mate Choice
Binter, Jakub ; Klapilová, Kateřina (advisor) ; Weiss, Petr (referee) ; Konečná, Martina (referee)
This thesis focusses on choice of partner, courtship, and stability of relationship. The emphasized phenomenon within this field are namely evolutionary origins of attractiveness and attraction, endocrine, behavioral, verbal and paraverbal displays. The courtship in this thesis is divided into three major phases - attractivity, proceptivity and receptivity - following suggestion of Beach, Freund and Money. Each of these phases is typical by certain types of behavior and reaction, such as hormonal response, vocal displays as is described in review of literature in the theoretical part. In the second, practical part, consists of four articles that address one specific phenomenon at time. The first article is focused on choice of partners in real world and their presence in sexual fantasy repertoire. The second article addresses vocal modulation when speaking to member of opposite sex who we find attractive or unattractive. The third article introduces hormonal response on possibility of gaining and loss of a potential partner in virtual courtship scenario. And finally, the fourth discusses role of female orgasm in relation to sexual and overall satisfaction in the relationship. The studies are original, and bring innovative insight to human mate-choice and courting, providing further scientific...

Analysis of a human body odour using comprehensive two-dimensional gas chromatography
Bušovská, Radka ; Sobotníková, Jana (advisor) ; Žáček, Petr (referee)
Body odour perception plays an important role in human mate choice, especially in women. It was previously proposed that women select partners whose body odour resembles that of woman's fathers. Yet, this phenomenon has only been confirmed using ethological studies based on subjective perception of body odour similarities. Therefore, the aim of my diploma thesis was to test this hypothesis instrumentally using comprehensive GC×GC-TOFMS and subsequent multidimensional analyses of body odour chemical profiles of male partners and fathers of adult women. Body odour sampling from left and right axilla of fathers and partners of 41 women (altogether 164 samples) was performed using cotton swabs, which were then frozen and extracted into hexane. Typical human volatile substances, such as hydrocarbons, carboxylic acids, esters, alcohols, aldehydes, ketones, sterols and terpenes were detected in all examined samples. Using a newly available "tile-based" chromatographic alignment algorithm, we obtained a set of 341 compounds systematically occurring in male axillary odour. The principal component analysis was used to calculate Euclidean distances for all pairs of the studied male subjects. These estimates of "chemical distances" revealed to be significantly smaller for father-partner pairs of individual...

Relationships among characteristics perceived from photos of faces
Machová, Kamila ; Flegr, Jaroslav (advisor) ; Děchtěrenko, Filip (referee)
Estimating others characteristics from facial cues plays an important role in our everyday lives. People usually agree in these estimates well and many of these estimates correlate. Majority studies consider one or few character- istics only and their respondents usually are in narrow ranges of ages. This study is partly based on rating of 13 characteristics of 80 men's and women's faces by respondents of various ages. These data were originally collected within yet unpublished study of Jaroslav Flegr, Amy E. Blum and Šebastian Kroupa. In this study I most strikingly found out that: i) older respondents of both genders rates photos of women as more attractive, ii) respondents spend more time by rating faces considered by themselves as more attractive or nice, iii) men rate people with different eye color as more attractive and women rate others with the same eye color as nicer, iv) preferences computed by two methods do not differ much. 1
