Document Summary

More learning in the beginning than the end. Inverse relationship or negatively accelerated, approaching 0 but never touches. In backward, the bell would end the meal. Shine light before ring bell before give food. Pair primary cs with another neutral stimulus (secondary cs) Some extinction trials are very long, such as phobia/fear, takes hundreds or thousands of trials, yet it still presents. Longer it takes to extinct, stronger the cs is. Even if extinction happens, if learning takes place the second time, it takes shorter. Extinction happens, yet cs can trigger cr randomly later. Degree of responding stimuli similar to training stimulus. High level of strength occurs to similar level (quality) stimulus. Ex. snake phobias, if people are afraid of rattle snakes, they still get scared when looking at pictures, or different types of snakes such as a cobra. White learned very sharply that 7 is the stimulus. S-r bond is strengthened by reinforcement, weakened by punishment.
