시간 압박이 시각 탐색 전략에 미치는 영향 모델링

Abstract

The previous Adaptive Control of Thought-Rational (ACT-R) cognitive architecture model has a limitation in that it cannot accurately predict human visual search strategy, because time effect, one of important human cognitive features, is not considered. Thus, the present study proposes ACT-R cognitive modeling that contains the impact of time using a revised utility system in the ACT-R model. Then, the validation of the model is performed by comparing results of the model with eye-tracking experimental data and SEEV-T (SEEV-Time; SEEV model which considers time effect) model in “Where’s Wally” game. The results demonstrate that the model data fit fairly well with the eye-tracking data (  = 0.91) and SEEV-T model (  = 0.93). Therefore, themodeling method which considers time effect using a revised utility system should be used in predicting the human visual search paradigm when the available time is limited.
