Study Notes
Taste Aversion Learning
- Conditioning can occur with long intervals between conditioned stimulus (CS) and unconditioned stimulus (US).
- Certain stimuli, such as flavors associated with toxins, are more readily linked in learning.
- Evolution may have favored mechanisms that help animals avoid slow-acting poisons through taste aversion.
One-Trial Learning
- Taste aversion requires only one pairing to form, leading to rapid learning.
- Extinction of aversion occurs, with no aversion present the next day, but recovery may happen after 28 days.
- Salient conditioned stimuli (CS) are learned quickly, indicating taste aversion is not unique among learning processes.
Long-Delay Learning
- In the presence of stimulus relevance, rats can encounter interfering stimuli during delay periods affecting conditioning.
- This form of learning does not set taste aversion learning apart from other types of conditioning.
Learned Safety
- Rats exposed to sucrose paired with lithium chloride develop strong aversion, while those exposed to sucrose with saline do not develop aversion, demonstrating the role of inhibitors.
- Simple prior exposure does not guarantee learned safety; preexposure to an inhibitory substance can actually impede the ability to learn conditioned inhibition.
Hedonic Shift
- Hedonic shift alters the perception of pleasure derived from specific foods, leading rats to develop negative responses to formerly preferred flavors like sucrose.
- A two-phase experiment showed that even after habituating to the unconditioned stimulus (US), the conditioned stimulus (CS) still evoked a negative reaction, suggesting CS palatability changes are distinctive in taste aversion.
Compound Potentiation
- In an experiment involving odor and taste, rats conditioned with both developed strong aversions to the odor when tested later, despite the flavor being absent.
- The salience of the potentiated cue is critical in establishing this aversion; however, the phenomenon of potentiation is not specific to taste aversion, as it can occur across other conditioning forms.
