Which term describes the effect of essential oils on emotions, memories, and instincts?

The term that accurately describes the effect of essential oils on emotions, memories, and instincts is psychological effects. This concept encompasses how essential oils can influence mood, evoke memories, and affect emotional states, often by interacting with the brain's limbic system, which is responsible for emotions and memory.

Essential oils have the ability to trigger responses that can either elevate one's mood, bring back specific memories, or even instigate instinctual reactions. For example, the scent of lavender may promote relaxation and alleviate stress, while citrus scents can invigorate and uplift the spirit. Understanding the psychological effects of essential oils is essential for effectively using aromatherapy to support mental and emotional well-being.

The other terms do not encompass the broad impact that essential oils have on the psychological aspect of a person's experience with scents. While emotional effects might seem relevant, it does not cover the full spectrum of how memories and instincts are involved.
