Answer:
b. events that it does not control.
Step-by-step explanation:
Classical conditioning can be defined as a learning process which involves repeatedly pairing two stimuli: conditioned stimulus and unconditioned stimulus. In classical conditioning, a response which is at first brought forth by the second stimulus is later brought forth by the first stimulus alone.
Basically, it is a process through which a living organism learns to associate stimuli and as a result anticipating events. Therefore, it is a learning procedure that helps us to understand when a neutral stimulus is paired with a conditioned response.
Hence, in classical conditioning, an organism forms associations between events that it does not control.
An example is the process of salivating in response to the aroma of a meal being prepared in the kitchen.
