Hi, I'm trying to find research which builds on the Quality vs. Quantity paper by Bellotti et al with respect to overload, unresolved tasks and email volume.
In particular, Hogan/Fisher report: "Bellotti et al. [2], examining email as a center for tasks, found that users’ perceptions of overload corresponds to the number of unresolved tasks in the users’ inbox (and not the volume of messages incoming)." (A Scale for Measuring Email Overload).
I am connecting this finding with the Zeigarnik Effect, and hoping that further research has been done in this area.
Thanks
