Existing research have investigated the effects of free will belief on aggressive behaviours. So far, studies have shown that when people's free will belief is denied, their motivation of self-control decreases, thereby increasing aggressive behaviours. An alternative and inconsistent account is that people who have strong belief in free will attributes the other party's attack to the actor's intention, which lead them to take revenge. Given that aggressions practically occur within a social interaction, the present study examined the relationship between free will belief and aggression in a social interactive situation. We hypothesized that people who have high free will belief will behave more aggressively when they are attacked by another individual. Based on a sample of 45 undergraduates, we measured free will beliefs and trait aggression as an individual-difference variable. We employed a modification of the Point Subtraction Aggression Paradigm in order to measure participants' aggressive behaviours. As a result, the effects of fatal determinism - a subscale of free will - were found significant. Specifically, when participants were unattacked by their interactive partner, those with low fatal determinism belief behaved less aggressively. Incurring no attack from the partner, participants may have experienced higher responsibility for taking aggressive actions themselves. Under such circumstance, having a low fatal determinism belief, and thus regarding their behaviour as undetermined by nature, may have further increased their sense of responsibility, consequently decreasing aggression. In contrast, when participants were attacked by their partner, aggressive behaviours increased on the whole relative to the non-attacked condition; receiving an attack may have simply provoked participants' motivation to revenge. This study highly suggests the relationship between fatal determinism belief and aggression in social interaction situations, offering a ground for future investigations including parameters to further explain the relationship.

The present research examined the possibility that a victim’s perspective-taking to the perpetrator, which has been argued to be a promotor of the victim’s forgiveness, does not take effect under certain personalities. Based on the finding that perspective-taking positively correlates with two of Big Five personalities (Toto, Man, Blatt, Simmens, & Greenberg, 2015), we examined whether openness and agreeableness moderate the degree of perspective-taking’s effect on forgiveness. In the experiment, we first measured participants’ personality on the Big Five scale and presented them with a vignette describing a situation where one becomes a victim of transgression; participants read the vignette under the manipulation of perspective taking (transgressor perspective or no perspective taking). Lastly, we measured participants’ levels of forgiveness. The results indicated that the participants who took the transgressor’s perspective reported weaker motivations of revenge and avoidance specifically when they were low in openness. Furthermore, perspective-taking mitigated the revenge motivation among people low in agreeableness while not among those high in agreeableness. The results suggest that people either high in agreeableness or in openness are likely to engage in spontaneous perspective-taking while the prompt to do so takes a more strong effect among those low in such personality traits.
