The current study aimed to examine whether exposure to prosocial content predicts prosocial behaviour and if antisocial content predicts cyber-aggression. Therefore, to explore if social learning occurs in an adult population. To investigate whether more hours spent online would create an online identity, that is aggressive or non-aggressive. A quantitative survey design was employed in which 114 participants were recruited. A correlational, cross-sectional design and convenience and snowballing sampling was used. Hours spent online weekly did not significantly predict online social identity. The current study found that prosocial and antisocial media content did not significantly predict their corresponding behaviours of prosocial behaviour and cyber-aggression. Therefore, there was no significant association between content exposure and behaviour in an adult population. It was discovered that younger participants spent more hours online weekly. Displaying an implication for the young people in the Irish population in terms of mental health (Akin, & Iskender, 2011).
