人们普遍认为,更多的注意力有助于学习新任务。然而,使用双任务范式,我们表明,无论次要任务的注意力是否分散,学习速度都是相同的。然而,在后来的测试中,只有当出现类似的分心时,才能记住在分心情况下学习的运动技能。在没有分心任务的情况下进行测试时,表现恢复到未经训练的水平。这个自相矛盾的结果表明,当更多的注意力资源可用时,表现会下降,这表明双任务环境或缺乏双任务环境是学习的重要环境。这种任务上下文相关的“储蓄”是显而易见的,即使当特定的次要任务或感官模态不同的学习和回忆,因此,它是双任务,而不是特定的刺激,提供了上下文。这一新发现表明,如果不考虑任务背景的作用,学习和康复计划的稳定性可能会降低。
It is generally thought that more attention helps when learning a new task. However, using a dual-task paradigm, we showed that the rate of learning was the same regardless of attentional distraction from a secondary task. Yet, when tested later, a motor skill learned under distraction was remembered only when a similar distraction was present. When tested without the distracting task, performance reverted to untrained levels. This paradoxical result, in which performance decreases when more attentional resources are available, suggests that the dual-task context, or the lack thereof, acts as a vital context for learning. This task context-dependent “savings” was evident even when the specific secondary task or sensory modality differed between learning and recall; thus, it is the dual-tasking, rather than the specific stimuli, that provides context. This new discovery suggests that without considering the role of task contexts, the stability of learning and rehabilitation programs may be diminished.
