Final answer:
Aromatherapy may improve memory by activating memories that bring back sights, sounds, and even smells of the past.
Step-by-step explanation:
Aromatherapy may improve memory by activating memories that bring back sights, sounds, and even smells of the past. Specific scents are often associated with our memories of places and events. That's because scents are more novel or specific than shapes or other things you might see. So an odor similar to that of your grandmother's kitchen or pantry might be more quickly associated with your memories of that place than a similar sight, which might be more generalized.
