Question

Quizplus · Accepted Answer

Extinction occurs when a previously conditioned response decreases in frequency when the CS (conditioned stimulus) is presented in the absence of the US (unconditioned stimulus). This is a form of learning where the association between the CS and US is weakened over time. Habituation refers to a decrease in response to a stimulus after repeated exposure, while adaptation refers to the process of adjusting to a new, changing, or different environment. Deconditioning is the process of reversing a conditioned response by gradually exposing the individual to the stimulus without the associated reinforcement.
