"The Impact of Passive Exposure on Learning Efficiency"

A study on mice suggests that passive exposure to stimuli, such as sounds, alongside active training, can significantly enhance the learning process, aligning with prior human research. The findings indicate that passive exposure helps the brain form foundational representations, making active learning more efficient. This insight could have implications for humans learning complex skills like playing a musical instrument or acquiring a second language, and may help in optimizing training schedules that combine passive exposure with active training.
