Concept:Classical conditioning is a learning process discovered by Ivan Pavlov, a Russian psychologist, in which a neutral stimulus becomes associated with an automatic response.
Explanation:In classical conditioning, an unconditioned stimulus
(UCS) naturally triggers an unconditioned response
(UCR) without prior learning.
When a neutral stimulus is repeatedly paired with the
UCS, it becomes a conditioned stimulus
(CS).
The
CS alone can then produce a conditioned response
(CR).
This response occurs automatically, or reflectively, due to the learned association between the
CS and the
UCS.
Therefore, the key characteristic is that the conditioned response is forced reflectively by the unconditioned stimulus.
Option B is wrong because classical conditioning was not formulated by Skinner; he is associated with operant conditioning.
Options C and D describe operant conditioning, where reinforcement and reward depend on the response made by the organism.
Answer:Option A is correct: The occurrence of conditioned response is forced reflectively by unconditioned stimulus.
