Effect of olfactory stimulus on simultaneous learning of conflicting motor tasks

Human motor learning research suggests that contextual cues such as visual and/or auditory stimuli contribute to reduce motor interference between conflicting motor tasks. In this study, we investigate whether an olfactory stimulus is able to reduce the motor interference in a motor learning paradigm (ABA). As a result, we confirmed that the group with different olfactory condition for Task A and B showed less motor interference. It suggests that olfactory stimulus works as a contextual cue for reducing the motor interference of conflicting motor tasks.
