Document Summary

Inborn predispositions (instinct) to learn were demonstrated with respect to: the separation in time between the cs and us is a crucial determinant of conditioning. Learning is unlikely to take place at delays of more than few seconds: e(cid:395)uipote(cid:374)tiality(cid:863) p(cid:396)e(cid:373)ise it does not matter what stimuli are used in conditioning. Cs will be equally good in all contexts: everything has the same potential to become a cs.

Exposed rate to x-rays gastrointestinal disturbance + nausea: sickness is the us. Tested drinking of the two waters after x-ray exposure. Control experiment with foot-shock: nausea could not be conditioned to light-noise, nor fear could be conditioned to a taste, taste-aversion conditioning occurs at delays of over 1 hour.
