Thorndikes puzzle box: cat in a box, fish outside box, association between lever and door strengthen over time with each serendipitous and intentional occurrence, measure latency in lever pressing. Skinner box: another form of associative learning requiring active response, rat presses lever, rat gets food (or drug) Operant conditioning: re-occurrence of behavior depends on consequence. Positive stimulus: something is added (candy or shock) Negative stimulus: something is removed (withdraw food) (withdraw shock) Drug reward: positive experience associated with drug (cocaine) Drug reinforcement: strengthening of the behavior that leads to drug consumption (lever pressing behavior: reinforcing property of drug is and indication of its abuse potential ( abuse liability ) Two procedures to study drug reward in animal: Drug self administration: more to follow later in notes.
