Final answer:
Repeated presentation of a stimulus paired with a response occurs in the Acquisition and Fluency phases of skill building, establishing and solidifying conditioned responses in classical conditioning.
Step-by-step explanation:
The repeated presentation of a single stimulus with a single response typically occurs during the Acquisition and Fluency phases of skill building. During the Acquisition phase, a neutral stimulus is paired with an unconditioned stimulus, developing into a conditioned stimulus that elicits a conditioned response. Over time, as the pairing is repeated, the strength of the conditioned response increases. Similarly, in the Fluency phase, the process involves solidifying that response so that it is strong and automatic.
Other important processes in classical conditioning include extinction, which is the decrease in the conditioned response when the unconditioned stimulus is no longer paired with the conditioned stimulus, and spontaneous recovery, which is the return of a previously extinguished conditioned response after a period of no exposure to the conditioned stimulus.
