Document Summary
Pseudo-conditioning: increased responding to the cs that occurs because of mere exposure to the us. Sensitization: increased responding to the cs that occurs because of mere exposure to the cs. If you devalue the us (by pairing it with a negative, changing it), the cr will go away. First-order conditioning = tone ----------- food: test: tone induces salivation. Second-order conditioning: light -------- tone: test: light induces salivation. Conditioning: tone -------- food: test: tone induces salivation; light induces salivation as well. Eye blink conditioning: us = puf of air to the eye. Ur = eye blink: cs = tone. Fear conditioning (skin conductance response scr: us = foot shock (not a conditioned stimulus because by itself it produces a strong response, not appropriate) Ur = jumping: cs = tone (by itself does not produce a response) Cr = autonomic & somatic responses (lack of movement, fear.
