Process in Evaluation Index of Intellectual Productivity Based on Work Concentration

K. Uchiyama, K. Oishi, K. Miyagi, H. Ishii, and H. Shimoda
Abstract—The authors have proposed a concentration time ratio (CTR) as a new evaluation index of intellectual productivity, which had been difficult to be quantitatively evaluated, with a concept of concentration on intellectual work. When quantitatively evaluating intellectual productivity with simple cognitive task method, the result is often affected by learning effect. In order to evaluate how office environment affects the CTR when an office environment is changed, a subject experiment was conducted in which the illumination condition of the room was changed. As the result, the performances of cognitive tasks were affected by the learning effect, however it was found that the index was affected not by the learning effect but by changing the illumination conditions.

Index Terms—Intellectual productivity, EM algorithm, cognitive performance, task and ambient light, work concentration.
