Quantifying the signal and noise of decision processes during dual tasks with an efficient two-dimensional drift-diffusion model
Kyungmi Noh, Yul Kang · Bernstein Conference 2024
Dual-task interference is a widely observed phenomenon where the decision-making becomes less efficient (slower or less accurate) [1]. This inefficiency is proposed to be a potential interference between the two decision-making processes, but the nature and extent of this interference have been debated [2]. For example, when two decisions are required simultaneously, dual-task interference might arise due to lower signals or higher noise available for each decision. Furthermore, the suppression of the signal may be partial or complete. However, the nature and extent of dual-task interference c
