Brainstiming with a GSS: exploring over time the effects of causal thinking on idea generation and synergy

Group support systems (GSS) development benefits from the theories methodologies, and findings of areas such as cognitive, learning, and group psychology but it also is often capable of contributing new insights into these areas that would not be attainable with any other technology or environment. Two studies are presented here that illustrate this capability. Both deal with idea generation in groups and they shed some light on how cognitive processes such as problem solving and learning are affected by different levels of interaction. The first study illustrates how a GSS tool can help us map the cognitive dynamics of idea generation over time in noncomputer supported and computer supported groups. The study also the GSS´s capability to show how increasing the causal thinking of the participants prior to brainstorming can increase their productivity. The second study shows how the GSS can help us document the amount of collaborative and synergistic problem solving that goes on in these types of sessions.
