 In Pavlov’s famous experiment, what did he call the… o unconditioned stimulus (UCS)? The meat powder o unconditioned response (UCR)? Saliva Flow o conditioned stimulus (CS)? Beel Ring o conditioned response (CR)? Mouth Salivation
 * Salivary Response **

 Pavlov demonstrated that the dog had formed a conditioned association between two events. What were those events? What did the dog actually learn? The bell sound with the foood. He learned that food came after the bell sound.
 * A New Salivary Response **

 In the example of a child who fears doctors, what label would you give to the painful injection? _ UCS _ UCR _ CS _ CR  <span style="font-family: 'Times-Roman','sans-serif';">In the example of a child who fears doctors, what label would you give to the presence of the <span style="font-family: 'Times-Roman','sans-serif';">doctor? <span style="font-family: 'Times-Roman','sans-serif';">Painful injection UCS no fear of doctor UCR presence of doctor CS fear of doctor CR
 * <span style="font-family: 'Times-Bold','sans-serif';">Acquisition **

 <span style="font-family: 'Times-Roman','sans-serif';">How could we demonstrate that acquisition had occurred—that is,  <span style="font-family: 'Times-Roman','sans-serif';">What is extinction? Unlearning/ removing a condition association  <span style="font-family: 'Times-Roman','sans-serif';">What is spontaneous recovery? The return of a conitioned assciation/ stimulus
 * <span style="font-family: 'Times-Bold','sans-serif';">Demonstrating Acquisition **
 * <span style="font-family: 'Times-Bold','sans-serif';">The child has acquired the fear of doctors/ needles **
 * <span style="font-family: 'Times-Bold','sans-serif';">Extinction **

 <span style="font-family: 'Times-Roman','sans-serif';">What is generalization? Triggering conditioned response to stimuli similar to the original
 * <span style="font-family: 'Times-Bold','sans-serif';">Generalization **

 <span style="font-family: 'Times-Roman','sans-serif';">What is discrimination? Learning to tell the difference between two similar stimuli
 * <span style="font-family: 'Times-Bold','sans-serif';">Discrimination **

 <span style="font-family: 'Times-Roman','sans-serif';">What is the CR in this example? Eye blink  <span style="font-family: 'Times-Roman','sans-serif';">What is the CS in this example? Beep  <span style="font-family: 'Times-Roman','sans-serif';">What is the UCS in this example? Air pump  <span style="font-family: 'Times-Roman','sans-serif';">What is the UCR in this example? Early eye blink
 * <span style="font-family: 'Times-Bold','sans-serif';">Conditioning an Eye Blink **

 <span style="font-family: 'Times-Roman','sans-serif';">Why are we interested only in the blinks that occur before the puff of air? <span style="font-family: 'Times-Roman','sans-serif';">Because that is the conditioned response to the tone. We want to know if the tone is effective.
 * <span style="font-family: 'Times-Bold','sans-serif';">Experiment Simulation **

 <span style="font-family: 'Times-Roman','sans-serif';">How would you interpret these graphs? Did your subject show evidence of stimulus generalization, or stimulus discrimination, or both?
 * <span style="font-family: 'Times-Bold','sans-serif';">Discrimination Trials **

<span style="font-family: 'Times-Roman','sans-serif';">There was a little of both discrimination and generalization. But eventually they were able to distinguish between the different tones.


 * <span style="font-family: 'Times-Bold','sans-serif';">Extinction Trials **

 <span style="font-family: 'Times-Roman','sans-serif';">How would you interpret these results? Has the conditioned response been extinguished in your subject? What would happen if we continued immediately with more trials? What would happen if we brought her back to the laboratory tomorrow for more trials?

<span style="font-family: 'Times-Roman','sans-serif';">We could state that the conditioned response has not been fully extinguished and could be brought back upon expereince. If we continued with more trials, the response would probably be reinforced, but with more time of trying.
