How achievement motive enactment shapes daily flow experience and work engagement: The interplay of personality systems.

In the present study, we examined how different forms of achievement motive interact to predict daily flow experience and work engagement. In particular, we conducted two diary studies to examine the main and interaction effects of motive enactment via extension memory (a macrosystem that enables holistic and experience-based information processing) and via the object recognition system (an alert-oriented macrosystem). In study 1, in line with personality systems interaction (PSI) theory, we found that motive enactment via extension memory fosters both day-specific flow and work engagement, whereas the conjunction of both forms of motive enactment has beneficial effects on flow and work engagement (two-way interaction). In study 2, we found that role clarity moderates the interaction of the two forms of enactment, indicating that the two-way interaction occurs when role clarity is low. Our results imply that the interplay of different dispositional forms of achievement motive enactment shapes how employees experience flow and engagement.
