Abstract

From an evolutionary perspective, this study aimed to identify effects of sex differences and childhood family unpredictability on risk-taking, future discounting and perceptions of exposure to violence among young people. Participants were 233 people (117 men, M = 18.96 years). The group with higher childhood family unpredictability presented higher risk of competition and life expectancy. Men presented higher rates of risk-taking and direct exposure to violence; women presented higher rates of indirect exposure to violence. We concluded that family unpredictability and sex differences did not show linear effects on the variables studied, as predicted from the evolutionary approach. The need to integrate biological, psychological and social theories and to develop appropriate instruments for the Brazilian population is emphasized.
