Abstract

Purpose This study re-analyzes Jung 2012's data using the time interval based analysis to examine if the process of idea generation is in good currency throughout the ideation sessions. In this way, the relationship between extraversion-introversion personality trait and ideation performance in the context of computer-mediated idea generation can be better understood. Design/methodology/approach A $2{\times}4$ factorial design was used, crossing personality differences (extraversion and introversion) with the degree of stimuli (0, 20, 40, and 80 high-quality ideas). Participants were randomly assigned to one of eight treatment conditions. The group simulator is used to measure individual level performance. The number of unique ideas generated by individuals and the exact time stamp when each idea was submitted were analyzed to compare performances. Findings The results show that introverts' performances significantly drops after about the middle stage of the ideation session, whereas extraverts do not seem to feel time constraints throughout the ideation session, resulting in superior divergent thinking, which is a major key to understand creative productivity in the problem-solving process. Since extraverts tend to yield a larger pool of ideas, another interpretation is that group composition with extraverts compared with introverts may create a logically larger group, which is important to improve the performance of idea generation group.

연구목적 컴퓨터 기반의 아이디어 생산 그룹들이 그렇지 않은 그룹들에 비해 여러 면에서 월등한 퍼포먼스를 보여 왔다고 컴퓨터 기반 브레인스토밍 연구들은 주장한다. 하지만 다른 연구들은 컴퓨터 기반 아이디어 생산 중에 발생하는 인지자극 시너지가 노미널 그룹과 비교했을 때 예상치보다 크지 않다고 지적한다. 컴퓨터 환경 하에서는 개인의 성향 차이에 따라 긍정적이고 부정적인 영향력이 다르게 작용한다. 따라서 본 연구는 아이디어가 생산될 때 발생하는 타임 스탬프를 분석하여 개인의 성향 차이가 아이디어 생산과정에서 어떤 영향을 미치는지를 관찰한다. 방법론 외향성/내향성 개인차와 아이디어 자극수위 (0/20/40/80개 아이디어)를 결합한 이원요인계획법을 사용하였다. 각 실험참가자는 무작위로 8개의 실험조건 중 하나에 할당되었다. 그룹시뮬레이터를 이용하여 실험참가자들의 퍼포먼스를 관찰하였다. 데이터베이스에 모아진 아이디어들 가운데 중복되지 않은 아이디어와 각 아이디어의 타임 스템프를 분석에 사용하였다. 결과 실험결과 (1) 내향성 집단은 외향성 집단에 비해 아이디어 세션 중반부 이후 생산성이 현저히 떨어지는 양상을 보인다. (2) 내향성 집단은 외향성 집단에 비해 현저히 적은 범주의 아이디어 생산 양상을 보인다. 따라서 컴퓨터 기반 브레인스토밍은 외향성 집단의 생산성 향상에 더 적합한 방법으로 보여진다.
