The effect of positive mood on intention to use computerized decision aids

While psychology research has indicated that positive mood enhances cognition and behavior, MIS researchers have largely ignored such potential effects on user acceptance of new IT. Using two cognitive theories on mood and memory, positive mood theory and the affect infusion model (AIM), we developed hypotheses about the contribution of these mood conditions on user acceptance of new IT with two levels of uncertainty. These hypotheses were investigated via an experiment using a computerized decision making aid. We found that positive mood increased acceptance, under both levels of uncertainty. These results held for both induced and naturally occurring positive mood. The results were consistent with positive mood theory but not with the AIM.
