Group brainstorming is what the authors believe to be\neffective for idea generation. It resolves the cognitive bottleneck of idea\ngeneration through social means. The collaboration between individuals broadens\nthe knowledge base and allows for aggerated creative effort. Yet, the effectiveness\nof group brainstorming varies by individual differences. This is because empirical\nstudies have shown that too much similarity inside a collaborating group makes\nidea generation worse. Therefore, it is important to ensure enough amount of\ndiversities in terms of concepts in a group. The authors define two type of diversity:\ninternal diversity (refers to background differences between group members that\noriginate from long-term learning and socialization) and external diversity (refers\nto stimulation supplied by external agents). The authors examine how one of\neach of these diversities (cultural difference and picture stimuli) affect the\nproductivity and diversity of ideas generated in group brainstorming. They find\nthat picture support in general enhanced brainstorming outcomes, and that\nintercultural groups especially benefited from this external stimulation. The\nresults suggest that technological design grounded in a systematic\nunderstanding of cultures can play a valuable role in converting cultural\ndiversity into creative outcomes.<\/p>\n\n\n\n
First, I like how the authors implement the picture support.\nAt first, I thought they just script the brainstorming ideas and choose images\non their discretion. Then I will probably question about the validity of the\ncongruence and stimulus pictures because: 1st<\/sup> they could be biased; 2nd<\/sup>\nthey might work differently in the participant\u2019s mind. To have a picture retriever\nand selector based on the user\u2019s choice of words is smart. In this way, conceptually\nthere should not be any bias towards the selection of pictures. On the other\nhand, since the authors did not report it, I am wondering how large is the\nlanguage pool. And how large is the picture pool. Then the authors help\nanswering the second question as well. The t-test suggests the effectiveness of\nthe picture selector. Which is a little bit surprising for me because in my own\nexperience dealing with TF-IDF, the accuracy was not as nearly good as theirs. <\/p>\n\n\n\n Another thing about the paper is the participants. As the\nauthors documented, two of the three questions in their main tasks were \u201cwhat\nif you have an extra thumb or extra eye?\u201d. These two questions have already\nbeen used in other studies before. Were the participants presented\/encountered\nwith these questions before? I think this is important to say because if by any\nchance the participants knew about the questions, the data gathered would\ndefinitely be biased. <\/p>\n\n\n\n When different cultural background is considered, what about\ncultural differences between the same nationalities? For example, participants\nfrom China might be somehow different than participants from HongKong or Taiwan.<\/p>\n","protected":false},"excerpt":{"rendered":" Summary Group brainstorming is what the authors believe to be effective for idea generation.
