What is the gumball that you receive from the machine called? • Positive Reinforcement
You go back to the gumball machine several times and it is empty each time. Why will you eventually quit going? • Extinction
What would you call your behavior if the dispenser was refilled and you bought a gumball again. • Spontaneous recovery
Why would you be able to operate this particular gumball dispenser, even if you had never seen this exact dispenser before? • generalization
Why would you choose to work a full dispenser instead of an empty one? (ok, I know it seems obvious, but what is the psychological term ) • discrimination Vs.
What would be happening if you put the quarter in the dispenser, but didn’t get your gumball until an hour later? • Delayed reinforcement • Is this effective? No.
Every second time you turn the dial on the gumball machine you get a gumball. In other words, you know that two turns of the dial= receipt of a gumball. This is called: • Fixed-ratio schedule.It always occurs at the same rate. Produces strong learning, but learning extinguishes quickly after the reinforcement schedule goes away.
If you didn’t get a gumball every time you put money in, and instead sometimes got the gum after three tries, some times after eight, and it was very unpredictable this would be: • Variable ratio schedule. Takes longer to condition a response, but learning is resistant to extinction. (Slot machines are a good example)
You walk by the gumball machine at 10:00 one morning and it says “Free Gumballs”. You walk by at 2:00 and the sign is gone, but the next morning at 10:00 the “Free” sign is back. This is an example of • Fixed interval schedule.
You pass by the gumball machine every day, and the “Free” sign is always random. You never know when it is going to be there. This is • Variable interval schedule. (Good example would be a teacher who gives “pop quizzes”.
You give up. You feel like you will never get a gumball and quit trying. This is called • Learned helplessness.
Reinforcement STRENGTHENS a behavior. What is the difference between a positive reinforcer and a negative reinforcer. • Positive reinforcer ______ a pleasurable stimulus or reward after a desired behavior. • Negative reinforcer _______ an undesirable stimulus.
So… which is positive, which is negative? • Your coach says “well done” after you make a big play. • You take an aspirin to get rid of a headache. • You hurry home in the winter to get out of the cold. • Your mom lets you stay out a ½ hour later because you received all A’s. • Saying “uncle” to stop your older brother from wrestling with you. • Faking a headache to get out of practice.
In contrast, punishment REMOVES a behavior by giving an unwanted consequence • Because the consequence is unwanted, the fear of this decreased the behavior. • Example: getting a spanking when you try to cross the street without looking. • Positive punishment: addition of something unpleasant. Ex: giving a speeding ticket. • Negative punishment: taking something desirable away… “omission”. • Problem with physical and/or positive punishment: does not teach correct behavior all of the time. For this “omission” is more effective… (Example: time out in daycare, “when you learn the correct attitude you can come back and play”).
