lecture 6 Flashcards
why is trace conditioning the most effective for learning?
the CS predicts the onset of the US
in stimulus intensity in the Pavlovian experiment, what was the process?
group A and B get the same intensity of US paired with a CS for 90 trials. after 90 trials, the intensity of the US is reduced for group B
are conditioned responses always permanent?
not always
extinction:
the gradual weakening and disappearance of a conditioned response
spontaneous recovery:
the reappearance of an extinguished response after a period of non exposure to the CS
stimulus generalization:
occurs when an organism that has a learned response to a specific stimulus responds in the same way to new stimuli that are similar to original stimulus
phobia:
irrational fears of specific objects or situations
stimulus discrimination occurs when:
an organism that has learned a response to a specific stimulus does not respond in the same way to new stimuli that are similar to the original
complex classical conditioning includes:
- second order conditioning
- sensory preconditioning
- blocking
- latent inhibition
- contextual conditioning
first order conditioning:
conditioning that involves a direct association between CS and US
second order conditioning:
when first order conditioned response is associated with a new CS by pairing the new CS with the old CS
sensory preconditioning:
two CS are paired together before an conditioning to a US occurs
blocking occurs when:
previous conditioning interferes with the ability to achieve new conditioning
latent inhibition:
when you repeatedly expose a neutral stimulus, it can make conditioning the neutral stimulus to a CS challenging. the neutral stimulus is already associated with no response
contextual conditioning:
when the CS and US association becomes intertwined with the environmental context
