Beyond Brainstorming: Exploring Convergence in Teams.

Area of Science:

• Cognitive Psychology
• Organizational Behavior
• Human-Computer Interaction

Background:

• Collaborative brainstorming generates many ideas, but effective methods for selecting and refining them (convergence) are less studied than idea generation.
• Existing research primarily focuses on electronic brainstorming, leaving a gap in understanding face-to-face convergence processes.

Purpose of the Study:

• To investigate the impact of two facilitation interventions—attention guidance and discussion encouragement—on the quality of collaborative convergence.
• To explore how these interventions influence team processes during idea convergence.

Main Methods:

• Experimental design was employed to test the effects of attention guidance and discussion encouragement during a convergence activity.
• Participants engaged in brainstorming followed by a convergence phase where interventions were applied.

Main Results:

• Both attention guidance and discussion encouragement interventions were positively correlated with higher convergence quality.
• Attention guidance supported coordination, information processing, and goal specification.
• Discussion encouragement enhanced idea clarification and combination.

Conclusions:

• Facilitation-based interventions significantly improve the quality of collaborative idea convergence.
• Discussion encouragement and attention guidance offer distinct but valuable contributions to the convergence process.
• Contrary to prior findings, team satisfaction increased after the convergence phase compared to the brainstorming phase.
