1 Classical Conditioning

2  Consists of repeated trials in which the CS and US are paired and the CR gradually develops  Most efficient conditioning occurs when:  CS slightly precedes US  CS comes to serve as a cue for the US  (example: flicker lights just before saying “class, we are going to have a pop quiz today”)  HOWEVER, conditioning will still occur if the two stimuli are presented simultaneously.

3  Presentation of the US is discontinued  Immediately following discontinuation of the US the CR will still occur, but will eventually stop.  After the CR stops, the behavior is considered extinct.  Example: If I condition you into thinking that flickering the lights means we will have a pop quiz and then I never give you the pop quiz, you will start to disassociate the meaning.

4  The spontaneous return of a conditioned response followed by extinction.  Example: All summer long, you do not operate under a school bell schedule, but immediately after your arrival back to SAHS, you remember what to do when the bell rings!

5  The process of relearning a conditioned response following extinction—only one or two pairings are needed.  Similar to spontaneous recovery, but the learning process is needed, just for a short period of time. (Maybe upon arriving back to SAHS, you need the entire day to remind you what the bell schedule is all about).

6  The transfer of a learned response to a different, but similar stimuli  Example:  CS= large black dog  CR= fear  Stimulus Generalization: Fear of small black dog or large spotted dog or medium sized brown dog (aka all dogs scare you!)

7  Learning to respond to one stimulus and to inhibit the response to all other stimuli.  Example:  CS= large black dog  CR= Fear  Stimulus Discrimination= No fear of a small brown dog or large white dog (etc). Only large black dogs scare you!

8  The conditioned avoidance of “poisonous” foods  Even if there has been a long interval between eating the food and becoming ill  Or even if there is only one pairing  Examples from your life experiences?

9  Intense irrational fear of a particular thing  Can lead to panic attacks  You have no reasonable explanation as to why you are afraid of this given thing.  Examples?

10  Conditioning technique to gradually reduce anxiety of a particular object or situation  Example: Peter’s fear of rabbits  Usually the therapy gradually exposes you to your fear until you learn there is no harm.
