Modeling Time Pressure Effect on Visual Search Strategy

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, the modeling 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. †

Quantitative Measurement of Frustration for Multitasking Environment

“…작업개입은 앞서 언급했듯 작업자가 수행하던 작업을 중지 시키고 다른 작업을 하도록 방해하기 때문에 작업자로 하여금 좌절감(Frustration)을 느끼게 한다 (Berkowitz, 1989). 또한 기존 연구에 따르면 이러한 좌절감의 증가는 작업자의 인지부하 증 가로도 이어질 수 있다 (Mark et al, 2008) (Choi and Myung, 2016;Gunzelmann et al, 2007;Park and Myung, 2014;Ritter et al, 2007) (Berkowitz, 1989;Roseman and Smith, 2001 (Berkowitz, 1989;Czerwinski et al, 2000;Johnson and Rule, 1986;Zillmann and Cantor, 1976). 이는 인지적 종결 욕구 이론에서도 일맥상통하게 설명하고 있는데, 작업이 끝나갈수 록 인지적 종결 욕구가 커져 그 때 작업개입이 들어오면 작업 초기에 비해 충족되지 못한 욕구가 크기 때문에 좌절감의 크 기도 커진다 (Niculescu et al, 2014 Frijda, 2007;Mehrabian, 1996).…”
