Operant conditioning is better than classical conditioning at explaining. alternating, random sequence. Laura accidentally touched a bare wire on an old light fixture, and she flinched when she was shocked by the electrical current. The variable ratio schedule is unpredictable and yields high and steady response rates, with little if any pause after reinforcement (e.g., gambler).
