Psychology of Learning (PSYC 210) Reinforcement: Making Stuff Happen Note: This lecture moves quickly. Read ahead and try to keep up.  Background Reinforcement happens!  It happens naturally in the “ REAL WORLD .”  This will involve more than simply presenting stimuli  It will require arranging consequences  Note the photos and who was associated with each method.  Recall the work of Thorndike and the  THE CATS  He called this,  TRIAL AND ERROR LEARNING  because it took the cats several attempts,  with several errors, before they performed consistently and fast  Thorndike’s  LAW OF EFFECT  suggested that responses could be made more probable by  some consequences and less probable by others.  Which experiments best capture “insight” learning?  KOHLER’S CHIMPS These are called,  LEARNING CURVES , time to complete a response, as a function of trials.  Real Life Examples  What are some real-life examples of behavior that might “improve with practice” when latency  is the behavioral  measure?  Disassemble and reassemble a  GUN  Disassemble and reassemble your  COMPUTER  Be sure to take note of my particular examples presented in class (all them including the video  snippets).
