    1. 1. October 23 Thorndike Skinner Reinforcement Cognition and Learning Reading/Class Quiz: Thursday, read/review p. 247-256 Optional Experiment, due Friday
    2. 2. B.F. Skinner
    3. 3. Operant chamber (Skinner Box)
    4. 4. Operant chamber (Skinner Box)
    5. 5. A pigeon turning • SHAPING—an operant conditioning procedure in which successive approximations of a desired outcome are reinforced • SUCCESSIVE APPROXIMATIONS— behaviors that are ordered in terms of increasing similarity or closeness to the desired outcome
    6. 6. Reinforcers: Immediate vs. Delayed?
    7. 7. Immediate vs. Delayed Immediate Reinforcers vs. Delayed Reinforcers: Walter Mischel developed the "Marshmallow Test" in the late 1960's and found children who are able to delay gratification tend to become socially competent and high-achieving adults (1989).

    12. 12. • INTERMITTENT (Partial)—the tendency for a response that is reinforced after some, but not all, correct responses – Fixed ratio—schedule of reinforcement in which the NUMBER OF RESPONSES required for reinforcement is ALWAYS THE SAME – Variable ratio – Fixed interval – Variable interval
    13. 13. • INTERMITTENT (Partial)—the tendency for a response that is reinforced after some, but not all, correct responses – Fixed ratio—schedule of reinforcement in which the NUMBER OF RESPONSES required for reinforcement is ALWAYS THE SAME – Variable ratio—schedule of reinforcement in which the NUMBER OF RESPONSES required for reinforcement is DIFFERENT for each trial or event – Fixed interval – Variable interval
    14. 14. • INTERMITTENT (Partial)—the tendency for a response that is reinforced after some, but not all, correct responses – Fixed ratio—schedule of reinforcement in which the NUMBER OF RESPONSES required for reinforcement is ALWAYS THE SAME – Variable ratio—schedule of reinforcement in which the NUMBER OF RESPONSES required for reinforcement is DIFFERENT for each trial or event – Fixed interval—schedule of reinforcement in which the interval of time that must pass before reinforcement becomes possible is always the same – Variable interval
    15. 15. • INTERMITTENT (Partial)—the tendency for a response that is reinforced after some, but not all, correct responses – Fixed ratio—schedule of reinforcement in which the NUMBER OF RESPONSES required for reinforcement is ALWAYS THE SAME – Variable ratio—schedule of reinforcement in which the NUMBER OF RESPONSES required for reinforcement is DIFFERENT for each trial or event – Fixed interval—schedule of reinforcement in which the interval of time that must pass before reinforcement becomes possible is always the same – Variable interval—schedule of reinforcement in which the interval of time that must pass before reinforcement becomes possible is different for each trial or event
