This experimental study examined the question as to whether it is more effective to have one pedagogical agent (Mentor) with combined expertise and motivational support or two separate agents – one with expertise (Expert) and one with motivational support (Motivator). It was found that having two separate pedagogical agents representing the two roles had a significantly more positive impact on both learning and the perceived value of the agents. This provides preliminary evidence for a pedagogical agent split-persona effect, suggesting that two separate and agents representing different functional roles may be preferable to one agent representing both of the roles.
