Extinction inhibits rather than erases the learned behavior – mainly expressed in context that it is learned Stimulus control – operant behavior is controlled by stimulus that precedes it o Discriminative stimulus – stimulus that signals whether response will be reinforced, sets the occasion o Ex – putting canvas in front of artist sets the occasion for painting to occur but doesn’t elicit painting Response in operant conditioning always requires choosing one behavior over other behaviors o Tendency to perform an action depends on reinforcers earned for it & reinforces earned for alternatives

Quantitative law of effect – effectiveness of reinforcer at strengthening response depends on amount of reinforcement earned for all alternative behaviors o Reinforcer less effective if there is a lot of reinforcement in environment for other behaviors o Reinforcer will be less reinforcing if there are many alternatives reinforces in environment Animals learn about specific consequences of each behavior & will perform a behavior depending on how much they currently want or value its consequences o Reinforcer devaluation – animal will stop performing instrumental response that once led to a reinforcer if reinforcer is separately made aversive or undesirable o Goal-directed behavior – behavior influenced by knowledge of association btwn behavior & consequence Sensitive to reinforcer devaluation effect o Habit – behavior that occurs automatically in presence of stimulus & no longer influences by animal’s knowledge of value of the reinforcer Insensitive to reinforcer devaluation effect Any reinforced or punished operant response is paired w/ an outcome in presence of some stimuli Process of observational learning involves 4 parts o (1) Attention – one must pay attention to what he or she is observing in order to learn o (2) Retention – one must be able to retain behavior he or she is observing in memory o (3) Initiation – one must be able to execute or initiate the learned behavior o (4) Motivation – one must b motivated to engage in observational learning Vicarious reinforcement – learning by observing reinforcement or punishment of another person

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
