Effects of Intervention Content and Timing on Group Task Performance

This study explores the main and interactive effects on group task performance of two types of intervention (interpersonal vs. task focused) administered at two different times (the beginning vs. the temporal midpoint of work). The results show that timing and content of intervention interact to affect group task performance. The discussion draws on qualitative data to expand on these findings and outlines conditions necessary for optimizing group performance on open-ended tasks.
