The RW model is essentially
the difference between the maximum possible learning and the amount already learned
How does the RW model explain blocking and how does the RW model fail to explain spontaneous recovery?
...
In a blocking experiment presenting a compound stimulus for the first time with shock will mean that each stimulus will elicit a CR
true
The RW model states that you learn the most
in the first trials
What is the first term delta-V in the RW model is defined a
the change in a associative strenght
Let's say you come home to your lovable dog that waits for you every day. Initially whenever you come into the room he barks and wags his tail in excitement to see you after a day at work. Pretty soon you begin to notice that he barks and is excited upon hearing the garage door open. What is the CS?
the garage door after coming home many times
In the Rescorla Wagner (RW) model, the alpha and beta are coefficients related to the (select all that apply)
- learning rate
- intensity of the US
- saliency of the CS
What would happen if the garage door opened and closed without you there many times?
Barking and waging would begin to extinguish
What is the UCR?
The barking
Initially, you place "free" food pellets in the hopper without the animal doing anything. The food is the
unconditioned stimulus
You then try to entice the rat to press the lever by taping a food pellet onto the right lever so that you can have animal press the right lever. You are
instrumentally conditioned
You then change the code in the program so that the animal has to wait on average 3 seconds after pressing the lever and then has to press the lever again. This schedule of reinforcement has changed from
CRF to VI3
In each trial where the VI3 has been reached and a pellet drops into the food dispenser, a cue light comes on while the animal is eating. The cue light is a
conditioned stimulus
Half of the animals you train to press the left lever and half of the animals you train to press the right lever for food. You are
counterbalancing the lever
After the animal shows an asymptotic response in a given trial, you change the code of your program so that the light does not come on, and pressing the lever does not result in a food pellet. The animals will go through
extinction
After the animal has decreased responding to about 10% of their baseline responding, you present the cue again and notice the animal starts to respond again even without the US. This is
cue-induced reinstatement
What is classical conditioning?
learning that occurs when a neutral stimulus (e.g., a tone) becomes associated with a stimulus (e.g., food) that naturally produces a behavior
What is spontaneous recovery?
the increase in responding to the CS following a pause after the extinction
What is renewal?
acquisition in context A, extinction in context B, and the response that happens in context A
What is generalization?
presenting untrained stimuli that are similar to the conditioned stimulus that elicits a conditioned response
In one of Pavlov’s studies, for instance, he first conditioned the dogs to salivate to a sound, and then repeatedly paired a new CS, a black square, with the sound. This is an example of
2nd order conditioning
The similarity between positive and negative reinforcement is that
They both strengthen a response
A child who is given a timeout after fighting with a sibling is an example of
Positive punishment
Someone who consumes drugs to take away their pain is an example of
negative reinforcement
Kohler's experiments with chimpanzees showed the principle of
insight learning
learning that is not reinforced and not demonstrated until there is motivation to do so is called
latent learning
The Bobo doll experiment shows the principles of
observational learning takes place whether the child sees a live, film, or cartoon version of events
