eli5: Why are certain sensory inputs pleasing, and some aren’t?

636 views

Beautiful paintings are pleasant to look at. Harmonised chords are pleasant to listen too. Fluffy fur is pleasant to touch. Without going into how we process these specific inputs (not 100% sure but think i know that bit) is there a more general/zoomed out reason why these please us on a fundamental level?

Also pls add psychology flair 🙂

Because certain electrical signals register to the brain as certain feelings, and some outside stimuli produce things that are harmful, so human brains evolved to register those things as painful or just a generally uncomfortable feeling. Other things can be helpful and send electrical signals that register as nice or comfortable.

Generally our senses are tuned to detecting patterns. Noise is thusly considered obnoxious. Complex patterns are pleasing and intriguing.
