How does habituation differ from extinction?

1. Habituation occurs when we learn not to respond to a stimulus that is presented repeatedly without change. 2. Only one stimulus is involved, and the change is a loss of attention to it, as with television noise that you stop noticing over time. 3. Extinction involves two stimuli: the conditioned stimulus is presented without the unconditioned stimulus, so the learned link between them weakens. 4. Option D therefore describes extinction, and option C describes spontaneous recovery. 5. Both processes reduce responding, which is why they are confused, but only extinction undoes a previously learned association. _Source: OpenStax Psychology (1st ed., CC BY 4.0), Ch 6 "Learning", §6.2 Classical Conditioning_
