Question

in the 1990s, singer - songwriter alanis morissette titled a song, \you learn.\ presumably, morissette meant that people:
form associations between stimuli.
acquire new behaviors through experience.
often acquire new behaviors by imitating others.
build mental representations of their surroundings.

Explanation:

Learning in a general sense refers to the process of acquiring new behaviors through experience. Forming associations between stimuli is more related to classical conditioning (a specific type of learning but too narrow). Imitating others is observational learning (a subset of learning through experience). Building mental representations is more cognitive - map related (also a part of learning but not the most general). The title "You Learn" implies the broad concept of acquiring new behaviors through experience.

Answer:

acquire new behaviors through experience.
