Final answer:
Dr. Robinson, as a strict Skinnerian learning theorist, believes that the consistency in an individual's behavior across situations is shaped by reinforcement history.
Step-by-step explanation:
Based on the information provided, Dr. Robinson, as a strict Skinnerian learning theorist, most likely believes that the consistency in an individual's behavior across situations is shaped by reinforcement history. Skinner proposed that behavior is motivated by the consequences we receive for our actions, and that behaviors that are followed by positive reinforcement are more likely to be repeated. Therefore, Dr. Robinson would attribute the consistency in behavior to the history of reinforcements an individual has experienced.
