Predispositions; Determinants of Cr; Conditioning in Humans
Biological Predispositions
Inborn predispositions to learn were demonstrated with respect to:
1. Separation in time between CS and US is a critical determinant of conditioning. Learning is
unlikely to take place at delays of more than few seconds
- Law of association
- Best way to condition is to have the CS occurring and overlapping the presence of US
o If delay between two, conditioning may possibly not occur at all
2. “Equipotentiality” premise- it does not matter what stimuli are used in conditioning. Any CS
will be equally good in all contexts
Taste-aversion learning (John Garcia)
Exposed rats to flavoured water and bright-noisy water
- Another stimuli was presented while drinking water (noisy= extra stimulation)
Exposed rats to X-rays gastrointestinal disturbance and nausea
- Nausea could not be conditioned to a light-noise
Tested drinking of the two waters after x-ray exposure
Control experiment with foot-shock
- nor fear could be conditioned to taste
- taste-aversion conditioning occurs at delays of over 1 hour
Flavor-Illness Associations (Linda Parker)
conditioned taste avoidance
- measured by consumption test
- appetitive and consummatory
- stay away from stimuli
Conditioned disgust
- Measured by taste reactivity test
- Consummatory
- Aversion to stimuli
Taste Reactivity- Measure of conditioned taste reactions
1. Flavoured solution is the CS
- Sucrose tongue protrusions
2. Drug treatment is the US, sickness is the UR
3. Pair CS with US
4. Present CS and measure the CR

Document Summary

Inborn predispositions to learn were demonstrated with respect to: separation in time between cs and us is a critical determinant of conditioning. Learning is unlikely to take place at delays of more than few seconds. Best way to condition is to have the cs occurring and overlapping the presence of us. If delay between two, conditioning may possibly not occur at all: equipotentiality premise- it does not matter what stimuli are used in conditioning. Any cs will be equally good in all contexts. Exposed rats to flavoured water and bright-noisy water. Another stimuli was presented while drinking water (noisy= extra stimulation) Exposed rats to x-rays gastrointestinal disturbance and nausea. Nausea could not be conditioned to a light-noise. Tested drinking of the two waters after x-ray exposure. Nor fear could be conditioned to taste taste-aversion conditioning occurs at delays of over 1 hour. Measured by consumption test appetitive and consummatory stay away from stimuli.
