“…Early idea-generation research used quantity as a measure of quality, assuming that if a sufficient number of ideas were produced, the resulting idea pool would be more likely to contain high-quality ideas (Osborn, 1953). This positive correlation has been confirmed in some studies (Diehl and Stroebe, 1987;Gallupe et al, 1992;Valacich et al, 1993), but other research has found that the correlation between quantity and quality is tenuous (MacCrimmon and Wagner, 1994), and still others have posited that there is in fact a negative correlation between quantity and quality (Graham, 1977;Connolly et al, 1990;Gryskiewicz, 1980). Studies that go beyond merely enumerating ideas require researchers to select a definition of one or more of the three constructs that are typically operationalized as the dependent variable(s): 1) idea quality, 2) idea novelty, which is sometimes referred to as rarity or unusualness, and 3) idea creativity.…”

Researchers and practitioners have an abiding interest in improving tools and methods to support idea generation. In studies that go beyond merely enumerating ideas, researchers typically select one or more of the following three constructs, which are often operationalized as the dependent variable(s): 1) idea quality, 2) idea novelty, which is sometimes referred to as rarity or unusualness, and 3) idea creativity. It has been chronically problematic to compare findings across studies because these evaluation constructs have been variously defined and the constructs have been sampled in different ways. For example, some researchers term an idea 'creative' if it is novel, while others consider an idea to be creative only if it is also applicable, effective, and implementable. This paper examines 90 studies on creativity and idea generation. Within the creativity studies considered here, the novelty of ideas was always measured, but in

“…In a more detailed way, Avouris et al remark that larger groups produce better results and generate greater activity, but that this activity is less homogeneously distributed between different members of the group [24]. Valacich et al reported an even more precise finding, observing that the activity rate per member increases with the size of the group when it is composed of members with diverse skills, whereas it decreases when the group is homogeneous [25].…”

This article presents a study concerning the comprehension of interactions in discussion forums. In particular, we approach the role of the complexity of individuals' written expression in the various facets of these interactions, such as the level of activity or the fidelity of the group's members. The study is based on the analysis of traces of activities highlighted by related works in the field of social psychology. Among other things, the results show that the amount of inter-group relations is directly connected to the complexity of individuals' expression.

“…Specifically, the majority of past work compared brainstorming conditions involving both interactive and nominal groups using either EBS or traditional tools (e.g., whiteboards and flip charts) in the following conditions: collocation with specialized process constraints (e.g., participant anonymity or turn-taking input), collocation without verbal communications (e.g., [62]), remote locations with computer-mediated communications, and remote locations in nominal condition. Barki and Pinsonneault provided a review of EBS in these varying settings [3].…”

Collaborative brainstorming can be a challenging but important part of creative group problem solving. Mind-mapping has the potential to enhance the brainstorming process but has its own challenges when used in a group. We introduce GroupMind, a collaborative mind-mapping tool that addresses these challenges and opens new opportunities for creative teamwork, including brainstorming. We present a semi-controlled evaluation of GroupMind and its impact on teamwork, problem solving and collaboration for brainstorming activities. GroupMind performs better than using a traditional whiteboard in both interaction group and nominal group settings for the task involving memory recall. The hierarchical mind-map structure also imposes important framing effects on group dynamics and idea organization during the brainstorming process. We also present design ideas to assist in the development of future tools to support creative problem solving in groups.
