The current research aims to describe general scheduling tendencies, evaluate the impact considering task end-times have on scheduling tendencies, and to assess links between scheduling tendencies and productivity. Throughout four studies, findings indicated that participants consistently preferred to schedule tasks on-the-hour (e.g., 9:00 or 10:00 vs. 9:15 or 10:30). When considering task end-times, this tendency for on-the-hour scheduling was reduced, especially when participants had five tasks or more to schedule. On-the-hour scheduling is likely a form of intermittent scheduling, which has been detrimentally associated with productivity. Although some correlational evidence was uncovered to support the notion that on-the-hour scheduling would be detrimentally linked to productivity (Study 2), replications showed no association between the variables (Study 3). These findings provide valuable information regarding scheduling tendencies, as well as the impact considering task end-times have on scheduling. However, more research is needed to examine links between on-the-hour task scheduling and productivity.
