Our results indicate, that trustworthiness decisions depend on several facial features, like gaze direction. The Collected Works of Plato, Vol.

Untrustworthy faces might look different from trustworthy faces, but this discrimination is not based only on universal, constant facial cues. Finally, a multiple regression analysis revealed that while several personality and behavior traits cooperative ability, Machiavellianism, sensitivity to norms, sex play a role in the development of prosocial behavior, the possibility of gaining reputation within the group remains a measurable causal factor of charity support.

That is, homosexuals are not against reproduction, on the contrary, they form a biological community together with them. Gaze direction of the target presumably affects judgments about perceived trustworthiness.

Homosexuals preserved this social, moreover, sociocultural, artistic function of theirs in eras when they suffered harassment.

Similarly, males increased their reproductive success through choosing females of the greatest reproductive value: In return, those who were willing to participate in a particular charity activity received a significantly higher score on the scales measuring sympathy and trustworthiness than the others.

People found more trustworthy same race faces, compared to other race faces. Several scholars raised the idea that during most stages of human evolution humans evolved in small groups with frequently repeated interactions and reputation-building mechanisms Fehr and RockenbachJohnson et al.

An experimental paradigm has been set up to test specific hypotheses concerning the role of humor in the context of short-term and long-term relationships and the differences between sexes in this respect. Striking differences between the sexes have been found in many of the measured 42 traits associated with physical attractiveness, financial condition, occupational status, domestic virtues, length of relationship, and marital status.


This is known as the own-race effect. The only solution to overcome homophobia lies in the understanding and acceptance of the biological, social and cultural function, role and necessity of homosexuality, listed above.

In the second study, the costly signaling model is used to examine reputation-building as a result of charity offers to strangers Birkas et al. Individual selection can favour cooperative strategies directed towards recipients that have helped others in the past. Empathy showed a relative independence of situational factors; ssubjects with higher scores of empathy were more likely to engage in yams activities than those of low empathy, regardless of whether they offered help on public or anonymous conditions and what the perceived degree of cost of altruistic behavior was.

An experimental analysis of a real life situation. Enter the email address you signed up with and we’ll email you a reset link. Subjects made more costly offers in public groups, while there was a roughly equal chance of making more and less costly offers in anonymous groups. Atlantisz,12 See Symposium by Plato in Hungarian in: Furthermore, many important aspects of social circumstances and personality traits could not be investigated appropriately under these experimental designs.

The cost of charity correlated with reputation building in the case of charity act judged as the most expensive giving assistance to mentally retarded childrenbut not in the other categories of charity offer.

Average faces with direct gaze were rated as most trustworthy. A robust finding in the cross-cultural literature is that people are able to recognize faces from their own race easier than faces from other races.

Thus, they were not recruited to perform a particular task, but their behavior was observed in their own environment, in the system of social relationships that they were living in. Research and theoretical systems of contemporary evolution science ofand have come to the conclusion that the above bereczkri is mistaken and not true1.

We beereczkei average faces one male and one female looking in 5 different directions direct, left, right, up and down. Similarly, the age and educational differences between spouses were associated with marriage quality.

For a long time, unfortunately, even evplcis regarded themselves to be the dead-end of biology. High-Mach persons were likely to refuse help when the others did not observe them but more willing to give assistance — especially less costly help – if their prosocial behavior occurred with the knowledge of the others.

The reproductive consequences of mate choice were evocis adaptive in a large Hungarian sample: The link between mating preferences and reproductive output may be mediated by marital success as a proximate mechanism.

In these experiments participants played various games such as reciprocity, trust and public goods games. Experimental games sometimes create artificial circumstances that people do not encounter in real situations. Subjects who were willing to participate in a particular charity activity gained significantly higher reputation scores, measured on a sociometry scale, than others did.

On the other hand, within the same race characteristics, judgments were consistent with the level of trustworthiness of the original Caucasian faces. Osiris, Budapest, Bereczkei T.: A theory has been based on the above statistic: The participants of the experiment did not take part in solving one or more tasks in an experimental game but they were induced to respond to an everyday problem while staying within the framework of their own life.

In one of our experiments Bereczkei et al. Other features of humor could have evolved through sexual selection, and may function as courtship tools in the mating process.

This responsiveness to the strategic distinction between the presence and absence of others can be also explained in terms of reputation-gaining and competitive altruism. We have been pursuing a research program that is focusing on the role of humour and laughing in mate choice Tisljar and Bereczkei
