o CR (conditioned response) “spreads” to similar stimuli Dogs moving to another location and thinking that maybe a school bell is the bell for their food Stimulus Discrimination o Occurs when an organism that has learned a response to a specific stimulus does not respond in the same way to new stimuli that are to the original stimulus. o CR is restricted to a specific stimuli Dogs adjust and realize which bell is for their food Acquisition – The initial stage of learning something; form a new CR Extinction – The gradual weakening and disappearance of a conditioned response tendency; banish a CR Spontaneous Recovery – The reappearance of an extinguished response after a period of no exposure to the conditioned stimulus; CR reappears after extinction and non-exposure Drug Abuse and Sign Tracking- Physical and or psychological dependence on the drug. Operant Conditioning Skinner o Is a form of learning in which responses come to be controlled by their consequences. o Classical conditioning regulated reflexive, involuntary responses, whereas operant conditioning governed voluntary responses.

o Reinforcement: occurs when an event following a response increases an organism’s tendency to make that response. (A response is strengthened because it leads to rewarding consequences. o Delayed reinforcement Learning at a slower pace o Primary reinforcement Events that are inherently reinforcing because they satisfy biological needs. Something reinforcing right from birth (Ex. Food, water) o Secondary reinforcement (Conditioned) are events that acquire reinforcing qualities by being associated with primary reinforces. Learned association from primary reinforces (Ex. Money, college degree) Skinner Box o Or operant chamber: is a small enclosure in which an animal can make a specific response that is recorded while the consequences of the response are systematically controlled. o Shaping – rewarding successive approximations of a desired behavior. (Giving a dog a treat when they learn a trick) Consists of the reinforcement of closer and closer approximations of a desire response o Reinforcement contingencies: are the circumstances or rules that determine whether responses lead to the presentation of reinforces. Skinners Contribution to WWII- used pigeons tracking behavior. Sent targets location when the beak was touched to the screen. Reinforcement schedules o Specific patterns that determine when a behavior will be reinforced / rewarded o Schedule of reinforcement: determines which occurrences of a specific response result in the presentation of reinforcement. o Once an animal has learned a response, would continuous reward or intermittent continue to maintain someone’s behavior?
