Lecture 2 Flashcards
types of associative learning
classical conditioning and operant conditioning
free energy principle
The brain would like to remain equilibrium whilst minimising entropy (surprise)
3 stages of classical conditioning
habituation, acquisition, extinction
4 things in classical conditioning
Conditioned stimulus (CS), Unconditioned stimulus (US), Conditioned response (CR), Unconditioned response (UR)
Interstimulus interval (delay conditioning)
Short delay
present CS for a small time by itself then US together with the CS
Long delay
same as short delay but present CS by itself for a little longer
ISI trace conditioning
present CS before US with an interval inbetween both
ISI simultaneously
present both CS and US at the exact same time for the exact same length
ISI backward conditioning
present US before CS
ISI temporal conditioning
refers to a specific time the CS is presented, is delay conditioning
Excitatory vs Inhibitory
Excitatory CS is one that will always predict the presence of the US
Inhibitory CS is one that will always predict the absence of the US. Inhibitor must pass the retardation and summation test to be true inhibitor
Retardation test
make a CS become inhibitory
then train a neutral stimulus to become excitatory
then train inhibitor to become excitatory, inhibitor should still have slower learning than neutral stimulus
Summation test
make an inhibitory CS
then make a neutral stimulus excitatory, then pair the neutral excitatory with the inhibitory, the neutral should have higher learning than when paired with the ex inhibitory
Spontaneous recovery
after extinction, have a break and then presenting the CS will have spontaneous recovery of the CR
Renewal
refers to context, extinction may not be the same when CS is presented in new environment. Spontaneous recovery refers to time where as renewal refers to context
Reinstatement (reminder effect)
have a break after extinction, during break only present US by itself. then there may be spontaneous recovery of the CR
