Abstract

Using self-determination theory and research on temporal aspects of work (e.g., time of day), this study investigates dynamic effects of task-specific motivation on well-being throughout the workday. We argue that the effects of task-specific intrinsic and extrinsic motivations on well-being outcomes (psychological vitality, job satisfaction) depend on the time of day in which the task is encountered, referred to here as workday accumulation. Our results showed that time of day interacted with intrinsic sources of motivation to predict job satisfaction, such that the relation was strong and positive early in the day and weak and positive later in the day. Time of day did not moderate the relationship of intrinsic task motivation with vitality, which was consistently positive throughout the day. The effects of extrinsic reasons for task pursuit on satisfaction and vitality were moderated by time of day, with extrinsic motivation having positive effects early in the day, but negative effects later in the day.
