This paper presents considerations on altruism and prosocial behaviour formulated on the basis of some experiments with the ultimatum game. In the first part it will discuss relations between expected utility theories, the characteristics of homo oeconomicus and a modern understanding of altruism. It will focus in particular on conceptual differences, indicating that we can find more than one definition of altruism in modern literature. The second part of the text will provide an overview of selected behavioural theories of prosocial (...) behaviour. It will also present the manner in which needs, social determinants, norms, and individual psychological features affect the propensity to behave in a prosocial fashion. (shrink)

The main goal of the paper was to obtain insights into how gender measures can be incorporated into quantitative research on risk-related behaviour. We explored relations between the measures (short versions of Bem Sex Role Inventory (BSRI), Personal Attributes Questionnaire (PAQ), and Traditional Masculinity-Femininity (TMF) scale) and their explanatory power in relation to risky behaviours (Decision Outcome Inventory, DOI). The sample consisted of 470 adults (238 men). The corresponding BSRI and PAQ subscales correlated significantly, while TMF correlated positively with the (...) femininity subscales. All the instruments demonstrated good internal consistency and the measures explained a significant portion of risky behaviour. The results suggest that, although sex is a proxy of behaviour, using a measure of the gender-related aspects of identity could enhance understanding of risk-related behaviour. Finally, men and women viewed themselves as equally masculine, indicating that gender stereotypes about desirability of agentic characteristics change. (shrink)
