The tabletop computer interface has the potential to support idea generation by a group using the brainstorming technique. This paper describes the design and implementation of a tabletop brainstorming system. To gain insights into its effectiveness, we conducted a user study which compared our system against a more conventional approach. We analysed the processes and results with the goal of g...

Divergent thinking tasks are a popular basis for research on group creative problem solving, or brainstorming. The brainstorming literature has been dominated by research that investigates group performance by measuring the total number of generated ideas using the original rules put forth by Osborn (1953). This review of empirical literature on brainstorming suggests that Osborn was right abou...

Collaborative brainstorming is often followed by a convergence activity where teams extract the most promising ideas on a useful level of detail from the brainstorming results. Contrary to the wealth of research on electronic brainstorming, there is a dearth of research on convergence. We used experimental methods for an in-depth exploration of two facilitation-based interventions in a converge...

In a recent article in Information Systems Research, Pinsonneault et al. (1999) present a thorough and compelling summary of theoretical factors that act to enhance and impair productivity in electronic brainstorming (EBS) groups as contrasted with traditional verbal brainstorming groups and nominal group brainstorming. They assume that all theoretical factors are equally important and remain c...

Previous research has shown that some groups using electronic brainstorming generate more unique ideas than groups using nominal group brainstorming, while others do not. This study examined two factors through which group size may affect brainstorming performance: synergy and social loafing. Groups brainstormed using three techniques to manipulate synergy and two group sizes to manipulate soci...

This “Perspectives” is the first “panel of a triptych,” in which I attempt to examine and cast a shadow on 3 activities commonly occurring in neuroradiology, radiology, and medicine in general. This one deals with group thinking, the second will examine the way we teach and learn radiology, and the last, how we do research. Some years ago, I used to ask my division members to sit down and have ...

Idea Generation has been a topic of creativity research for centuries. A wealth of creative processes has been devised to overcome difficulties at the perceptual, emotional, and cultural levels. Brainstorming in particular has grown to become synonymous with idea generation. This paper discusses our preliminary study on current conception of brainstorming and calls for future studies that help ...

Early studies of brainstorming showed that individuals tend to generate more and better ideas than groups. But recent studies depict a more complex picture, reinforcing the need to better understand the interplay between individual and group ideation. Group influence can be one way to address the complex interplay between ideas in brainstorming. We define group influence as the degree to which ...
