We examined the impact of two different personality measures on creativity. From the Five Factor Model (FFM), we predicted that openness to experience would positively impact creativity. From revised Reinforcement Sensitivity Theory (r-RST), we predicted revised Behavioural Activation System (r-BAS) would positively impact creativity and revised Fight/Flight/Freezing (r-FFFs) would negatively impact creativity. We hypothesised that r-FFFs would continue to predict creativity with openness to experience controlled. Consistent with Elliot and Thrash (2010), we predicted that mastery would mediate the impact of r-BAS on creativity. Results found support or all partial support for all hypotheses. Originality (one aspect of creativity) was negatively impacted by r-FFFs when openness to experience was controlled. An indirect effect rather than full-mediation was found for the effect of r-BAS on creativity through mastery. Future research should examine measures beyond the FFM to improve understanding of personality and behaviour. Workplace environments should aim to minimise fear in employees to gain creativity benefits. Managers should also aim to enhance goals and direction in employees to increase the impact of employees’ r-BAS drives on creativity.
