People use information systems to seek information. Transformative technologies have increased the number of information sources and amount of time people consume interacting with them. However, life is overloaded with unpredictable and uncontrolled information sources, generating anxiety, stress, and uncertainty. While the Management Information Systems field is concerned with understanding how to increase adoption of information systems that represent formal information sources, transformative technologies are selected by users and used to perform work tasks. Given this scenario, we present a new approach to investigate user behavior in this information context. The objective of this research in progress is to investigate information stimulus event, which influences human information behavior in the context of the large number of information sources. We hope to provide a new model to assist the academic community, practitioners, and society to understand this phenomenon, as well as to improve IS design and help individuals to advance their experience and interaction with IS.
