据报道，同时学习两个相互矛盾的运动任务（即具有相反力场的任务）是很困难的。奥苏等人。 (2004) [11] 揭示了这种双重学习是通过为每个运动任务分配不同的上下文线索来实现的（例如，在运动任务 A 期间显示红色，在运动任务 B 期间显示蓝色）。基于之前的研究，我们旨在研究嗅觉刺激是否可以作为情境线索。我们进行了行为实验，要求参与者在不熟悉的力场中学习伸臂任务。作为上下文线索，我们使用了柠檬和薰衣草的气味，它们具有相反的功能：柠檬被认为可以增强精神或身体任务的表现，而薰衣草被认为是一种放松剂。我们的结果表明，柠檬气味可以减少学习相互矛盾的运动任务后的错误数量，而薰衣草则不然。这表明特定的嗅觉线索可以作为上下文线索来促进矛盾运动任务的同时学习。
Simultaneous learning of two contradicting motor tasks (i.e. tasks with opposing force fields) has been reported to be difficult. Osu et al. (2004) [11] revealed that such dual learning is achieved by attributing different contextual cues to each motor task (e.g. displaying a red color during motor task A and a blue color during moto task B). Based on this previous study, we aimed to study whether olfactory stimuli can serve as contextual cues. We conducted behavioral experiments in which the participants were required to learn arm-reaching tasks in unfamiliar force fields. As contextual cues, we used odors of lemon and lavender, which have opposing functions: Lemon is believed to enhance mental or physical task performance, while lavender is considered to be a relaxant. Our results showed that lemon odors reduced the number of errors after learning contradicting motor tasks, while lavender did not. This suggests that specific olfactory cues can serve as contextual cues to promote the simultaneous learning of contradicting motor tasks.
