Final answer:
Reinforcement for correct responding in a motor imitation trial is usually social.
Step-by-step explanation:
In a motor imitation trial, reinforcement for correct responding is usually social. Reinforcement is the implementation of a consequence to increase a desired behavior. In the context of motor imitation, when a student accurately imitates the motor action, they are typically reinforced with social praise, such as verbal praise, a smile, or a thumbs up. Unlike tangible reinforcement which involves providing physical items like stickers or tokens, social reinforcement is often sufficient for encouraging and reinforcing correct responding in motor imitation trials.
