SENSING&RESPONDING: pavlovian learning Flashcards
simultaneous conditioning
conditional and unconditional stimuli presented at the same time
delay conditioning
conditional stimulus starts first, after a period of time the unconditional stimulus starts and they continue together
trace conditioning
condițional stimulus presented first but stops, delay before unconditional stimulus presented
backward conditioning
unconditional stimulus presented before conditional stimulus
describe the blocking effect
conditional response does not occur in response to a newly introduced conditional stimulus due to prior training with a different conditional stimulus
what does the blocking effect show evidence for?
in order for response to a US, there must be no prior learning to produce CRs to any other conditional stimuli
what is the CS pre exposure effect?
pre exposing animals to a conditional stimulus which will be used later in a procedure
what is the CS pre exposure effect evidence for?
it is more difficult to learn to respond in a new way to familiar stimuli than to new ones
what is high order conditioning?
a conditioning procedure that employs an acquired behaviour rather than innate
describe the process of high order conditioning
- innate stimulus elicited behaviour is carried out until a CR is acquired
- the acquired CR is conditioned to a new CS
describe the anticipation in eye blink conditioning
- delay procedure
- eyelid movement recorded
- CS delivered, delay and then US delivered
- eye response starts after US delivery in the first trial
- in later trials, the response starts before the US delivery
define pavlovian learning
learning to predict or anticipate something based on a preceding occurrence
- discovering what stimuli signal what events
what is the anticipated thing?
unconditional stimulus
what is the preceding thing?
condițional stimulus
describe CS US belongingness
organisms learn to respond to CS if the CS belongs to the US - if it does not belong, they respond slowly or not at all
describe drug intolerance in reference to compensatory CRs
over repeated administrations lead to reduced effects of the drug
- larger doses needed to produce same effect
- as CR increases over repeated administration, tolerance develops
