D) Deconditioning

Question

Quizplus · Accepted Answer

Extinction occurs when a previously conditioned response decreases in frequency when the conditioned stimulus (CS) is presented in the absence of the unconditioned stimulus (US). This happens because the association between the CS and the US is weakened over time, leading to a reduction in the conditioned response. Habituation is a form of non-associative learning where the response to a stimulus decreases with repeated exposure, but it is not related to classical conditioning. Adaptation refers to a general process by which organisms adjust to changes in their environment. Deconditioning refers to the process of reversing a previously established association between a CS and a US.
