Paola has been classically conditioned to fear a red light because it has been paired with a loud noise. If the light is repeatedly presented without the loud noise she will eventually stop being afraid of the light. In this instance, _____ has occurred.
extinction
BF Skinner contribution and experiment
-behaviorism; he was controversial - Elaborated on Thorndike's law of effect -Skinner box/operant chamber with rats: bar and key, one for food and one for water as reinforcers, see how the rat reacts depending on if they are thirsty or hungry and what they want
What are 4 types of partial reinforcement? Explain
1. fixed ratio: reinforcement occurs after a set number of response 2. variable ratio: reinforcement occurs after a unpredictable number of responses 3. fixed interval: reinforcement occurs after a set amount of time 4. variable interval: Reinforcement occurs after a unpredictable amount of time
taste aversion
A classically conditioned dislike for and avoidance of a particular taste that develops when an organism becomes ill after eating the food. John Garcia Adaptive sense

Why can pigeons easily be conditioned to peck to obtain food
Because it is a naturally adaptive behavior. They already naturally peck at things when eating or trying to obtain food

Ivan Pavlov experimental work
Classical conditioning with a dog Attached a tube in the dogs cheek to collect saliva Putting food (US) in a dogs mouth made the dog salivate (UR) Associated the food (US) with a bell (NS) so the bell alone (CS) led to salivation (CR)
Discrimination classical vs operant conditioning
Classical: being able to identify between the the CS (bell) and similar ones (different tones) Operant: being able to distinguish between the behavior that is being reinforced (jumping up and down is awarded with food) compared to similar ones (jumping side to side not awarded)
if Pavlov only presented the food (US) after the bell (CS) but not the tone, tuning fork, or buzzer, the dog would learn to discriminate between the sounds and only drool (CR) to the bell. This is an example of d

Immediacy and delayment of reinforcement and how it impacts behavior
How did Garcia and Koelling's taste aversion studies help disprove Gregory Kimble's early claim that "just about any activity of which the organism is capable can be conditioned . . . to any stimulus that the organism can perceive"?
In cases, not all activity can be conditioned. In some cases, such as taste aversion, only some things can be due to preparedness for animals to associate the food with sickness and avoid it for better survival in's tea dog the sight or sounds with it.
Acquisition
In classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response.
unconditioned response (UR)
In classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food is in the mouth, Pavlov exp
How do cognitive processes affect classical and operant conditioning?
In their dismissal of "mentalistic" concepts such as consciousness, Pavlov and Watson underestimated the importance of the effects of cognitive processes (thoughts, perceptions, expectations)
A reinforcer...the likelihood that the behavior will increase
Increases
positive reinforcement
Increasing behaviors by presenting positive stimuli, such as food. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response.
negative reinforcement
Increasing behaviors by stopping or reducing negative stimuli, such as shock. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. (Note: negative reinforcement is not punishment.)
Isaac: Could you take me to the mall? Dad: (Continues reading paper.) Isaac: Dad, I need to go to the mall. Dad: Uh, yeah, in a few minutes. Isaac: DAAAAD! The mall!! Dad: Show me some manners! Okay, where are my keys . . . Can you identify the behavior and the reinforcement for both Isaac and his Dad?
Isaac: his behavior of wining was reinforced because his father gives in and river him. His behavior was positively reinforced cause now, since rewarded after doing it, is going to likely do it more Dad: his behavior of driving was reinforced because his sons wining stopped. His behavior was negatively reinforced because his is likely to drive his son more because the annoying wining was taken away

Robert Rescorla showed what
Show that an animal can learn the predictability of an event. The more predictable the association, the stronger the condition response. Its as if the animal learns an expectancy, an awareness of how likely it is that the unconditioned stimulus will occur
How does immediacy of the reinforcement impact behavior?
Some animals will need immediate (within 30 seconds for instance) reinforcement in order to tie the reinforcement to the behavior. Human animals respond to delayed reinforcement...even learn to delay gratification as a point of maturity.

John Garcia. What did he discover, what was his experiment
challenged the idea that all associations can be learned equally well Exposed a group of rats to a particular taste, sight, or sounds (NS) and later also to radiation or drugs (US) that led to nausea and vomiting (UR). Even if sickened hours after that flavor, they later avoided the flavor (CS). They had taste aversion but no conditioned aversions to sights or sounds.

Mom is frustrated because 3-year-old Maya has started to spit frequently. She has decided to temporarily put away one of Maya's toys every time she spits. Mom is going to continue this until Maya has stopped spitting. • Explain whether Mom's plan uses reinforcement or punishment. • Explain whether Mom's plan is a positive or negative form of reinforcement or punishment.
~ the plan uses punishment because it is designed to reduce the frequency of spitting. ~ this is negative punishment because toys are being taken away from maya
