目的：在日常生活中，当我们执行双重任务时，任务绩效普遍降低。由于这些性能的降低（即，双重任务干扰）是造成各种事故的原因，例如福尔斯，双重任务的重复练习（即，双任务训练）经常被实施以减少双任务干扰。然而，各种事故的风险随着双任务训练时间的延长而增加，因为双任务干扰无法避免。因此，在双任务训练中更快地实现训练目标是很重要的。本研究旨在探讨双任务训练与认知任务训练相结合是否会加速训练效果，实验设计包括4组：1）认知任务训练组，2）双任务训练组，3）认知任务和双任务训练组，4）非训练组。我们采用了双任务，包括膝盖伸展和听觉反应，并使用N-back任务作为认知任务。结果两组受试者在两种任务中的双任务干扰均减少。然而，在认知任务和双任务训练组的人数谁实现了双任务成本的减少显着高于其他groups.Conclusion：这些研究结果可能有助于开发一种有效的方法，减少双任务干扰和解决问题所造成的双任务干扰在日常生活中。
Objective: When we perform dual-tasks in daily life, task performance is generally reduced. As these reductions in performance (i.e., dual-task interference) are responsible for various accidents such as falls, the repeated practice of dual-task (i.e., dual-task training) is often implemented to reduce dual-task interference. However, the risk of various accidents increases with longer dual-task training, as dual-task interference cannot be avoided. Therefore, it is important to achieve training goals more rapidly during dual-task training. This study sought to determine whether a combination of dual-task training and cognitive tasks would accelerate training effects.Design: The experimental design included four groups: 1) cognitive task training group, 2) dual-task training group, 3) cognitive task and dual-task training group, and 4) non training group.Method: We assessed single- and dual-task performance before and after the 2-week training sessions. We adopted a dual-task involving knee extension and an auditory reaction, and used N-back task as a cognitive task. On the other hand, dual-task training was the same method to assess dual-task performance.Result Dual-task interference was reduced in all groups in both the tasks. However, the number of participants in the cognitive task and dual-task training group who achieved a reduction in dual-task cost was significantly higher than those in other groups.Conclusion: These findings could contribute to the development of an effective method for reducing dual-task interference and resolving issues caused by dual-task interference in daily life.
