The idea

“If an animal acts differently after something happens over and over, that's habituation.”

Habituation needs repetition, and so do a lot of other kinds of learning. So the one word gets stretched over every change.

The short version

The mistake: If an animal acts differently after something happens over and over, that's habituation.

What's actually true: Habituation is only a response fading because a harmless stimulus keeps repeating.

  1. Habituation is a drop in response to a stimulus that keeps repeating and brings nothing good or bad. The animal stops spending energy on it.
  2. In associative learning, an animal links a cue or an action with an outcome. That covers learning to seek a reward and learning to avoid harm.

On the exam: Call it habituation only if a response faded and the repeated stimulus was harmless.
