Document Summary

Behaviour: * = biologically significant, one significant, one insignificant, insignificant stimulus becomes significant through association = Cs-us = conditioned excitation; the cs is an exciter (cs+) increases: signal = bell, significant event = receiving food. Notation: us -> ur, us gets paired with cs, cs -> cr. Example 1: alcohol poisoning (us) -> sickness (ur, alcohol poisoning (us) -> gets paired with tequila (cs, tequila (cs) -> sickness (cr) or aversion (cr) Example 2: presentation of food (us) -> salivation (ur, presentation of food (us) -> gets paired with ringing a bell (cs, ringing a bell (cs) -> salivation (cr) Example 3: scary movie (us) -> getting scared (ur, scary movie (us) -> gets paired with scary music (cs, scary music (cs) -> getting scared (cr) Unconditioned response and conditioned response could be the same or. Cognitive conditioning just happens, don"t have to do anything (cid:523)e. g. pavlov"s experiment(cid:524) Cs-no us = conditioned inhibition; the cs is an inhibitor (cs-) .
