scape goat effect
Blame nausea from food they normally don't eat
Bias to associate the things we eat with nausea overrides knowledge and that's why we still blame food even though the IV is what it really is
Very strong bias
Blaming chemotherapy induced nausea on novel food
Motivational significance: aversive
Motivational significance: appetitive
auto shaping protocol (Pavlovian)
sign tracking vs goal tracking
sign tracking (autoshaping)
The tendency to approach and interact in biologically relevant ways to those stimuli which signal the availability of food or other US stimuli.
-if you Devalue the outcome (food) - is NOT driven by stimulus outcome association, resistant to the unconditioned stimulus
goal tracking (autoshaping)
movement toward and possibly contact with a stimulus that signals the availability of a positive reinforcer, such as food
Devalue the outcome (food) - stop their behavior towards the food port/lever Less likely to work harder for cocaine
Sign tracking vs goal tracking
Sign-trackers are more likely to develop an addiction to cocaine or something like that See how hard they'll work for cocaine Sign-trackers keep going even when shocks are introduced Goal-trackers stop when shocks are introduced
conditioned flavor preference
Learn sucrose (aka lemon) is associated with sweet - develop preference for it
Very hungry Consume even more of flavor 1 Preference is strong and flavor reminds them of something caloric
Conditioned Flavor Aversion
when consumption or particular taste is associated with bad stuff, it will taste bad in the future
Universal taste responses
Make the mouth movements when something is sweet vs when something is bitter/sour, etc.
Stimulus has acquired the sweet characteristics of mouth movements and body changes the way you respond to the flavor as a result of conditioning
Hedonic vs aversive reactions based on the tastes
The observation that in taste aversion learning, the flavor conditional stimulus actually becomes unpleasant.
Liking vs. Wanting
liking = taste reactivity
wanting = consumption
conditioning where the US is a stimulus that acquired its ability to produce learning from an earlier procedure in which it was used as a CS
second order conditioning example
Tone light food associations Food (US) --> salivate (UR) Light --> food --> salivate Tone (2nd CS) --> light (CS) --> food (US) --> salivate (CR) Tone --> salivate (CR) Tone essentially is like a CS
what does second order conditioning alter?
Second order conditioning alters the liking and wanting of a cue
when one stimulus is conditioned as a CS, another stimulus with which it was previously associated can also become a CS
what does sensory preconditioning alter?
Sensory preconditioning does not change liking, only alters wanting.
