Abstract

According to the Search for Ideas in Associative Memory theory ideas in a brainstorming session do not come one by one but rather in “trains of thought” which are rapid accumulations of semantically related ideas In order to visualize these trains of thought we developed a brainwriting tabletop interface enabling users to link successive ideas together by means of graphical ropes To test the effectiveness of this device 48 participants in groups of four brainstormed for 20 min on the tabletop in one of two conditions either with the trainofthought interface with graphical ropes or without the ropes control condition The results show that visualizing the associations between ideas enabled the participants to produce longer trains of thought We also assessed originality by collecting the unique ideas in the whole corpus of ideas produced by the different groups and observed that the trainofthought condition produced more original ideas than the control one One interpretation of this finding is that visualizing trains of thought increases cognitive stimulation ie improves creativity by making others’ ideas more intelligible to the brainstorming partners in comparison with the classical visualization of ideas as independent items
