Are shared ideas used? Despite the pervasive use of electronic media for idea generation and idea sharing, the extent and quality of idea integration and use in electronic brainstorming is relatively understudied. This study empirically examines an attention-based theory of idea integration that underscores the importance of IS user interface design. Building upon Cognitive Network Model of Creativity (CNM) and ability-motivation framework, the attention-based view of idea integration formulates a causal model for idea integration in the context of user interface. The causal model focuses on the effect of idea visibility and prioritization on idea integration and the extent to which those relationships are moderated by information diversity and group size. A full description of the experimental study and its implications are provided in the paper.
