The impact of risk communication on risky behaviours has not been well researched, whereby risk communication strategies rely on assumptions that people interpret risk information in a logical and rational way and alter their behaviour to reduce the risk even though existing scientific literature is contrary to this. Furthermore, in psychology there is still an ongoing debate between hereditary and social influences when explaining the role of sex differences in risky behaviour. This study, based on evolutionary explanations of fear and anxiety, the biological model of the continuum of the inevitability of threat and the investigation of relevant physiological structures (especially the amygdala and hippocampus) and the behaviours that these physiological structures cause, raise hypotheses about the impact of specific and clear information about risky behaviour and the role of gender in this context. Using an experimental approach, the effects of gender and clear and specific information about risk on risky behaviour as well as their interaction on a sample (N=70) of voluntary students of the Croatian Catholic University were investigated. Balloon Analogue Risk Task (BART) was used as a measure of the dependent variable of risky behaviour. BART was modified in one of the experimental conditions to include clear and specific risk information. Research results have shown that there is no significant difference between female participants in the condition where risk information is present and female participants in the condition where risk information is absent, and that there is a significant difference between male participants when risk information is present and when risk information is absent, whereby male participants in the condition where risk information is present showed a higher level of risky behaviour than male participants in the condition where risk information is absent. Furthermore, it was determined that in the condition where risk information is present there is a significant difference between men and women, whereby male participants showed a higher level of risky behaviour than female participants. Finally, there was no significant difference between men and women in the condition where risk information was absent.
