Classisal Flashcards
what is non associative learning
habituation
learning about an isolated event
what is associative learning
learning about the predicitive relationship between two events ie this follows this
describe pavlovs dogs
dog salivate to food (ucs = ucr)
dog salivate to food and sound of bell (ucs+ns= ucr)
dog salivate to sound of bell (cs = cr)
what association is learnt in classical conditioning
the association between an otherwise neutral stimulus which does not produce a response, and a biologically important stimulus which produces an innate response
describe the eyeblink in rabbits test
puff air into eye of rabbit as tone plays
when tone plays - rabbit blinks as expects puff of air
describe fear conditioning in rats test
recieve shock when light is turned on
when light presented - heart rate increases
describe autoshaping in pigeons
pair light with food stimulus
when light comes on, peck at it
pairing light with presentation of food so think it is food
describe garcia et al 1960 taste aversion test in rats
1. rats given sacchrine flavoured water pair with light and clicking noise group 1 - shocked group 2 - x rays both avoid water via smell
- sacchrine flaboured water offered either with light and click or without light and click
group 1 - shocked - avoid when with light and click but drink when without light and click
group 2 - x ray - avoid whether or not light and click is present
what does garcia et al suggest about associative learning
associative learning is selective
x ray cause sickness which is internal and shock cause pain which is external
pair the external stimuli with external consequence but not internal stimuli
describe ilene bernstein 1970
patients in chemotherapy have speicifc aversion to icecream when given before session
link food with the nausea and sicknes
how is the amygdala important in classical conditioning
amygdala linked to fear respoinse
involved in the detection of suprising events and learning
coordinates with prefrontal cortex
describe hare et al 2008 and the amygdalas role in classical conditioning
reaction time to fearful faces shorter than for happy and vise versa in prefrontal cortex
fear suggest threat so processed faster
describe sehlmeyer et al 2011 in human fear conditioning
phobics show increased fear response to phobia related stimuli
exagerated responses make more susceptable to develop phobia
aquisition of phobia - response increase from baseline
extinction of phobia - response decrease below baseline
describe phelps et al 2001 in human fear conditioning
expect shock with blue square not yellow
greater response to threat stimulus
increased blood o2 to amygdala
suggests involved in processing instructed fear
what kinds of innate behaviours can be conditioned?
salivating startled jump blinking sweating food consumption or avoidance fear
