Dual-task interference causes many accidents. Working memory (WM) training has the potential to reduce dual-task interference. However, an effective method of WM training for reducing dual-task interference has not been established. This study aimed to examine whether WM training using auditory stimuli (auditory WM training) or visual stimuli (visual WM training) would more effectively reduce dual-task interference. Twenty-two young adults performed an N-back task with auditory or visual stimuli for auditory or visual WM training, for 2 weeks. The authors assessed dual-task interference before and after each training. The authors used a hierarchic multilevel model for these assessment parameters. As a result, visual WM training might be more effective for reducing dual-task interference than auditory WM training.

听觉或视觉工作记忆训练对双任务干扰的影响。

双任务干扰会导致许多事故。工作记忆（WM）培训具有减少双任务干扰的潜力。但是，尚未建立一种有效的WM训练方法来减少双任务干扰。这项研究旨在检查使用听觉刺激（听觉WM训练）或视觉刺激（视觉WM训练）的WM训练是否会更有效地减少双任务干扰。22名年轻人接受了听觉或视觉刺激的N背训练，进行了听觉或视觉WM训练，为期2周。作者评估了每次训练前后的双重任务干扰。作者对这些评估参数使用了分层的多级模型。结果，视觉WM训练可能比听觉WM训练更有效地减少双任务干扰。
