Document Summary

Second order conditioning: first-order cs = tone. Test: tone induces salivation: second-order cs = light. Test: light induces salivation (*note: light is never paired with. Sensory preconditioning the food: sensory pre-conditioning = tone light. Test: tone induces salivation; light induces salivation as well. Multiple level responses: blinking etc. ) behaviour: autonomic (increases in heart rate; salivation; sweating, motivational (emotions, changes in affect) fuel, energy towards, somatic (movement toward/ away stimulus) An index used to measure the reduction responding for food during the presentation of a cs associated with an aversive us. Suppression ratio index = b/(a+b: b = # of responses during the cs, a = # of responses before the presentation of the cs. If no fear, a=b and sr=0. 5; if much fear, b=0 and sr=0. Laws of association: frequency of cs-us association, intensity and novelty of cs and of us.
