What theory did Rescorla and Wagner originate?
The theory of Pavlovian conditioning presented by Robert Rescorla and Allan Wagner in 1972(the Rescorla-Wagner model) has been enormously important in animal learning research. It also has been applied in a variety of areas other than animal learning.
How did Rescorla and Wagner explain blocking?
One of the most important contributions made by the R-W model is that it predicts Blocking and Unblocking. Blocking occurs when a novel stimulus (because it is novel it has no predictive value) is presented together with a well-established CS (whose predictive value Page 2 is essentially equal to λ, that is, 1).
What is the central idea of the Rescorla-Wagner theory?
A central tenet of Rescorla and Wagner’s model of associative learning is that the reinforcement value of a paired trial diminishes as the associative strength between the presented stimuli increases.
What did Rescorla and Wagner show about conditioning quizlet?
Robert Rescorla and Allen Wagner were the first to realize what about classical conditioning? those in a vegetative state showed trace conditioning but those who were unconscious did not.
How does the Rescorla-Wagner model explain overshadowing?
Overshadowing is classical conditioning phenomenon which is explained well by the Rescorla-Wagner Model. For example, if a CS1 and CS2 compound is used to predict a US, it can been seen that CS2 elicits less conditioned response than if it had been paired with the US independently.
How does Rescorla-Wagner explain overshadowing?
What was Little Albert conditioned to be afraid of?
The Little Albert Experiment demonstrated that classical conditioning—the association of a particular stimulus or behavior with an unrelated stimulus or behavior—works in human beings. In this experiment, a previously unafraid baby was conditioned to become afraid of a rat.
What did Rescorla do?
Rescorla was perhaps the greatest pure experimental psychologist of the 20th century. He was the undisputable heir to Ivan Pavlov, the foundational figure in experimental psychology and the person who introduced the phenomenon of the conditioned reflex and provided its first theoretical interpretation.
What did John Garcia find in his studies of taste aversion quizlet?
Terms in this set (23) An animals biology plays a large role. What did John Garcia find in his studies of taste aversion? They showed that an animal can learn the predictability of an event.
What is an example of overshadowing in psychology?
Overshadowing is when the first stimulus has no more stimulus control. An example is a teenager who can study in a classroom, but not in front of the a group of cheerleaders.
