Document Summary

All about pairing a signal (s) with a significant event (s*) Cs-us=conditional excitation; the cs is an excitor (cs+) Excitors create the response or behaviour: frequency of the cs-us association, intensity and novelty of the cs and us, contiguity (cs-us sequence/timing) Cs-no us=conditioned inhibition, the cs is an inhibitor (cs-) The light is presented periodically with the burger (though not all the time) Testing for conditioned inhibition: summation test: cs (tone), then the cs2 (light)=cr to tone stops, retardation-of-acquisition test: cs2 (light) difficult to condition to a us. Increase in responding that occurs to a stimulus when it is presented sometimes along with an unconditioned stimulus. Sign vs. goal tracking signals a positive reinforcer stimulus stimulus. Fascinating neurological differences in sign vs. goal tracking. Sign tracking: the movement towards the possibility of contact with a stimulus that ex) a squirrel who uses the leaves of an oak tree to find acorns.
