Document Summary
An index used to measure the reduction responding for food during the. B = # of responses during the cs. A = # of responses during the presentation of the cs. Suppression ratio presentation of a cs associated with an aversive us. Laws of association: frequency of cs-us association, intensity and novelty of cs and of us, contiguity = cs-us sequence/timing. Delayed conditioning = cs is activated and after a delay the us is turned on and they both turn off at the same time. Trace conditioning = cs turned on then off and then after a period of time the us is turned on. Simultaneous conditioning = cs and us occur on and off at the same time. Backward conditioning = us turned on, turned off and then cs is presented. Which one if best at turning off conditioning? delay conditioning. Delay conditioning give all factors equal will give the most amount of conditioning to a conditioned stimulus.
