Tutorial 4 Flashcards
Allergist task: are causal ratings for compounded foods higher or lower?
lower - this is likened to an overshadowing effect
What is the cue competition effect
cues presented in compound compete for a limited amount of associative strength with an outcome.
Allergist task: A+ in multiple trials, then AB+ and CD+. How does B relate to C or D?
B has a lower causal rating than C or D due to blocking by A
Associationist explanation of causal reasoning?
people decide the extent to whether a cue causes an outcome to the extent that the cue BRINGS TO MIND the outcome
Explain the predictive model?
Causal model constructed that ENCOURAGES blocking. Cues are the CAUSES of the outcome meaning they must COMPETE if in compound!
Explain the diagnostic model?
Causal model constructed that DISCOURAGES blocking. Cues are the EFFECTS of the outcome meaning they don’t have to compete when in compound.
Would a predictive or diagnostic model lead to more blocking ?
predictive.
What difference does it make if a subject is thinking critically and not intuitively?
They will be more sensitive to the causal model
How does blocking rect to cognitive reflection?
it is higher for lower cognitive reflection in the predictive model
What is Value Modulated Attentional Capture
stimuli that predict high value outcomes capture more attention than low ones
How would you extinguish the VMAC to drug related stimuli to extinguish addiction?
exposure to drug related cues but don’t administer the drug. Effect does not extinguish if subject explicitly believes the contingency is still in operation, if you know that you are in a context in which you wont get high then it is not effective
Strength of US is decreased in inhibitory learning from L=1 to L=0.5, what asymptote does Va decrease to?
The new lower asymptote at 0.5, it was previously at 1 but now slowly approaches 0.5, NOT 0
What happens if you have a zero contingency and then add in another CS2 to intertrial intervals where the US was previously presented alone?
Durlach 1983 you get better conditioning to the original CS. It ‘rescues’ learning about CS1
