As information and communication technologies (ICT) become widely available and users gain more experience with them, functionality and usability are not the only expectations of users any more. This study investigates the impacts of individuals’ affective evaluations of ICT on adoption and use decisions at the initial and continued use stages. We clarify distinctions between affective and cognitive evaluations, between object-based and behavior-based evaluations, and between positive and negative evaluations. Two object-based affective evaluation concepts are introduced that are believed to be independent of each other and play different important roles in forming ICT adoption and use decisions: Perception of Positive Affective Quality (PPAQ) and Perception of Negative Affective Quality (PNAQ) of ICT. A longitudinal study on a learning management system use in a mandatory use context confirmed that PPAQ and PNAQ are distinct concepts that have different effects on commonly studied ICT adoption/use factors: perceived usefulness (PU), perceived ease of use (PEOU), and attitude toward using the ICT (ATB). Additional analyses provide more insight into the dynamics of ICT use phenomenon over time.
