Bell Work Identify an Unconditioned Stimulus and the Unconditioned Response it produces.
Organisms relate stimulus to consequences. Operant Conditioning
Thorndike Thorndike's puzzle box Learning happens by “accident” – unsure of outcome of behavior… Cats placed inside box At first, unsure After repeated exposure, learned to press lever
B.F. Skinner Skinner Box : Also called operant chambers Rodents, typically Press button to receive food
Reinforcement Positive Negative Something is added as a reward Most effective way to change behavior Negative An undesirable stimulus is removed to reward behavior The beeping in your car if no seatbelt
Primary and secondary reinforcers Primary = biological Food, drink, pleasure, etc. Secondary = conditioned reinforcers Money, happiness from doing “good”, etc.
Punishment Punishment, especially violence, leads to aggression Must be immediate and consistent Positive Stimulus is added Spanking Negative Stimulus removed Grounded from computers/cell phone
Shaping The form of the response is changed until the desired response is achieved. Circus elephant tricks…
