Abstract (eng)
Initial perception of an individual highly influences numerous attributes, that are
attached to that person. Hand grip strength (HGS), which represents physical body strength, expresses specific characteristics, such as perceived dominance or masculinity. The survey used in this thesis used images of generated faces, so called morphs, to find out if the male face with the highest HGS value is perceived more attractively and trustworthily. Furthermore it was expected that, during ovulation, women score the morph with highest HGS better. All five morphs were generated by combining 26 German male faces, aged between 18-32 years. The generated faces only differ systematically in assigned HGS. The survey was taken by 151 female students of the University of Vienna. All of them were shown the same faces to evaluate different characteristics like attractiveness using sliders. For both, perceived attractiveness as well as perceived trustworthiness, an inverse
u-shaped relation was proved. Compared to all other morphs, the strongest morph was assessed significantly less attractive as well as significantly less trustworthy. Overall, a positive correlation was found between attractiveness and trustworthiness. Due to an insufficient sample size, the hypothesis with respect to women preferring the strongest morph during ovulation could not be investigated. Perhaps, the strongest morph reminds of a „Babyface“ and his round face could be associated with a high BMI, which results in less attractive perception. As all morphs display a neutral facial expression, they are supposed to appear less trustworthily,
especially compared to a smiling face.
