Modeling one-choice discrete-continuous dual task

Abstract

Performing two tasks simultaneously has been always a challenging issue. The effect of difficulty factor has investigated on discrete-continuous motor-cognitive dual-task (DT) using manual tracking task and auditory discrete stimuli. 25 participants that took part in this experiment were asked to track the target while responding to auditory stimuli at the same time. Two different levels of difficulty for tracking tasks were applied to the experiment. The effect of different difficulties was investigated via several factors as error rate, the response time (RT) using the Drift Diffusion Model (DDM) method. The results show that with different drift rates the model is consistent with RT of different difficulty levels.
