Other learning principles Skinner had:- Shaping => reinforcing successive approximations as desired response. -Used to increase frequency of new behaviors -Examples:- rat in skinner box, roommate behavior. Discrimination => responding differently to different environmental stimuli - When is the pay off happen vs. when it does not - Ex. Pigeons, disk picking, light. - Ex. Kid, questionable T.V shows, different parents Extinction => reduction of responding when reinforcement decreases. - Example. Rat, bar pressing. Attractive server:- - Behaviors that get extinguished, may return spontaneously Two basic types of reinforcement:- 1) Continuous reinforcement => every time response id displayed, reinforcement is given - Pros vs. cons:- - Pros=> will see lots of behavior, behavior is learned quickly
