Recent developments in the information and communication technology have made it possible to provide managers with large amounts of information. Although information technology has been instrumental in improving the access and flow of information, it has also been instrumental in creating an overload of this same information for businesses and organizations.
Consequently, the problem of information overload and ways to manage it have been the focus of a great number of studies in the MIS literature. A large body of the studies that examine the effects of information overload view decision makers as rational actors who process information inputs into decision outputs and whose performance is constrained by their cognitive structure. Recent psychological investigations have shown that affective states such as positive mood can regularly and significantly influence and enhance one’s cognitive structure and flexibility. In the light of these psychological studies, it is reasonable to believe that mood may influence the effects of information overload. That is, it is reasonable to expect that the performance of the people in positive mood will be better than their control counterparts under the conditions of information overload. Thus, this study intends to extend prior work on information overload by establishing mood as an important variable in the existing models.
