learning
“ relatively enduring change in behavior resulting from experience. Learning occurs when an animal benefits from experience so that it is better adapted to its environment and more prepared to deal with it in the future”

three types of learning
nonassociative
associative
social
social learning
“involves acquiring behaviors and predictive associations between stimuli or events through interactions with others.

associative learning
Habituation
“leads to a decrease in a behavioral response after repeated exposure to a stimulus. ”

“The increase in a response because of a change in something familiar is ”
dishabituation
“ much of what psychologists have learned about nonassociative learning has come from studying simple invertebrates such as
“Aplysia, a type of marine snail”
“Habituation can be demonstrated quite easily by touching the animal repeatedly, which initially causes it to withdraw its gills. After about 10 touches, it stops responding, and this lack of response lasts about 2 to 3 hours. Repeated habituation trials can lead to a state of habituation that lasts several weeks.”
.
Sensitization
“leads to an increase in a behavioural response after exposure to a stimulus.”
“The stimuli that most often lead to sensitization are those that are
meaningful to the animal
“What is the primary difference between habituation and sensitization?”
“Habituation decreases a behavioral response, whereas sensitization increases a behavioral response.

“classical conditioning, also known as
Pavlovian conditioning
“Ivan Pavlov, a Russian physiologist, was interested in
salivary reflex
neutral stimulus
“unrelated to the salivary reflex, such as the clicking of a metronome, is presented along with a stimulus that reliably produces the reflex, such as food. The neutral stimulus can be anything that the animal can see or hear as long as it is not something that is usually associated with being fed”
conditioning trial
the pairing of a neutral stimulus
unconditioned response
it is unlearned
(salvation by food)
unconditioned stimulus
the food - without training, the food leads to salivation (UR)
conditioned stimulus
“the stimulus that elicits a learned reaction”

“However, the CR and the UR are not always identical:
The CR usually is weaker than the UR. In other words, the metronome sound produces less saliva than the food does

“An unconditioned stimulus elicits an involuntary (unconditioned) response without learning. A conditioned stimulus comes to elicit an involuntary (conditioned) response by being associated with the unconditioned stimulus.”

Acquisition
“is the formation of an association between a conditioned stimulus (here, a metronome) and an unconditioned stimulus ”
extinction
“The conditioned response is extinguished when the conditioned stimulus no longer predicts the unconditioned stimulus ”

“that extinction replaces the associative bond but does not eliminate that bond. Extinction is a form of new learning that overwrites the previous association: The animal learns that the original association no longer holds true”

mental processes that underlie conditioning (2)
“ (1) Classical conditioning is a way that animals come to predict the occurrence of events, and
(2) the strength or likelihood of a CR is determined by how accurately the CS predicts the US. ”

“The Rescorla-Wagner model states ”
“ that an animal learns to expect that some predictors (potential CSs) are better than others”

“according to the Rescorla-Wagner model, whether a conditioned association is acquired, maintained, strengthened, or extinguished is determined by”

“the extent to which a US, or its absence, is unexpected or surprising. Learning theorists refer to the difference between the expected and actual outcomes as prediction error.”

prediction error is considered a positive prediction error happens when
something unexpected happens or to a further extent
negative prediction weakens the
CS-US association
Rescorla-Wagner model
“A cognitive model of classical conditioning; it holds that learning is determined by the extent to which an unconditioned stimulus is unexpected or surprising.”

“ Stimulus generalization occurs when
“ Stimulus generalization occurs when stimuli similar but not identical to the CS produce the CR (FIGURE 6.11a). Generalization is adaptive because in nature the CS is seldom experienced repeatedly in an identical way”
.
“Stimulus discrimination occurs whenn
“an animal learns to differentiate between two similar stimuli if one is consistently associated with the US and the other is not”

micheal jordan example
“Through classical conditioning Michael Jordan (the CS) came to evoke positive feelings (the CR) because of his athletic achievements (the US). Once he acquired these qualities, Air Jordans (the new CS) also became popular (the CR) because they were paired with Michael Jordan (the old CS).
