Ch 3 – non-associative learning

involves only one stimulus at a time; simplest form of learning -habituation -sensitization -priming

learning to associate one stimulus with another or to a new response

lack of response to originally noticeable stimuli: -ex: learning to ignore the hum of the air conditioner

exposure to strong stimulus increases responding to a later stimulus -ex: startle more to loud noise after seeing a scary movie

prior exposure to a stimulus improves the organism's ability to recognize that stimulus later -ex: word stem completion task

-dishabituation: novel stimulus can renew response -allows researchers to determine whether the subject discriminates b/w habituated stimulus and novel stimulus -ex: will infant look longer if new face is presented

experience w/ a set of stimuli improves the organism's ability to distinguish those stimuli -can also occur through discrimination training

simply being exposed to the stimuli results in perceptual learning ex: rats exposed to shapes are better at recognizing shapes later on

perceptual learning can also occur through discrimination training -organism learns to distinguish stimuli via feedback about stimulus class

latent learning of rats in maze

when siphon is touched: -sensory neuron fires -glutamate is released -receptors on motor neuron activated -action potential -muscles retract gill

habituation -SEE DIAGRAM- (p4 last slide)

after shock to tail, stronger withdrawal of gill after light touch of siphon or mantle
