Conditioned excitation: food = unconditioned stimulus (us, bell = conditioned stimulus (cs, salivation = unconditioned response (ur, salivation with bell = conditioned response (cr) Conditioned inhibition: two ways, it is conditioning but you supress the response, differentia inhibition 2 stimuli cs1 = phone, cs2 = pen. When you see the phone you get food, when you see the pen you get nothing. Pen = no unconditioned stimulus: conditioned inhibition 2 steps. Step 1 normal classical conditioning see phone get food. Us = puff of air to the eye. Cr = eye blink: fear conditioning. Cr = autonomic arnd somatic responses . Video of rat give shock of varying intensities not aversive because painful, but unexpected then you condition with buzzer cs us cs us (about 5 times ) Put them in chamber and give cs the animal stops and does(cid:374)"t (cid:373)o(cid:448)e scared of sound: place conditioning.
