This lesson unpacks the science of operant conditioning — how organisms learn by connecting behaviors to their consequences. From Thorndike's Law of Effect and Skinner's famous conditioning chamber to the dopamine-driven pull of slot machines, Section 6.3 of OpenStax Psychology 2e reveals the hidden mechanics behind why we do what we do. Along the way, the lesson also challenges Skinner's "black box" view of the mind with Tolman's landmark maze experiments on latent learning and cognitive maps. In this video: • Thorndike's Law of Effect and how Spirit the dolphin illustrates behavior shaped by consequences • The math of operant conditioning: why positive/negative mean addition/subtraction, not good/bad • Positive and negative reinforcement explained with seatbelt beeps and horseback riding • Drawbacks of physical punishment and the psychological rules for an effective timeout • Shaping through successive approximations — and how it applies to teaching a toddler to clean their room • The four partial reinforcement schedules and why the variable ratio (gambling) is nearly impossible to extinguish • Tolman's maze experiment, latent learning, and how cognitive maps challenge Skinner's black-box behaviorism #OpenStax #Psychology #OperantConditioning #BehavioralPsychology #LearningScience OpenStax Content adapted from "OpenStax Psychology 2e", by OpenStax licensed under CC BY 4.0.
