Abstract
The effects of task and reward interdependence on perceived effort, helping behavior, and group performance were investigated in a laboratory setting. Fifty-seven groups with 3 undergraduate students in each group completed two consecutive copyediting activities. Helping behavior was highest in groups with high task interdependence. However, no support was found for the interactive effects of task and reward interdependence. Differences across time were found for perceived effort, helping behavior, and performance. The implications of these findings suggest that the increased task complexity, introduced through the presence of high levels of task interdependence, can mitigate the positive performance effects of high levels of helping behavior and effort.
