3 Avoidance Contingency Before: Sid will hear a click immediately Behavior: Sid maintains an erect posture. After: Sid won’t hear a click immediately

4 Avoidance Contingency Before: You will have an accident soon Behavior: You drive carefully After: You won’t have an accident soon

5 Avoidance Contingency The immediate, response-contingent prevention of an aversive condition resulting in an increased frequency of that response

6 Avoidance Contingency Before: You will soon stumble and fall Behavior: You walk perfectly After: You won’t soon stumble and fall

7 Avoidance of an Aversive Event Example: overcorrection following training on eye contact… Try using reinforcers first Meet ethical standards

8 Avoidance of an Aversive Event Before: Jimmy will have to overcorrect in 2 sec Behavior: Jimmy looks at the instructor After: Jimmy won’t have to overcorrect in 2 sec

9 Avoidance of Loss Contingency The immediate, response-contingent prevention of loss of a reinforcer resulting in an increased frequency of that response.

10 Avoidance of Time-Out Before: The child will soon have to leave the classroom for 3 minutes Behavior: The child works hard After: The child won’t soon have to leave the classroom for 3 minutes

11 Avoidance of Reprimands Reprimands are specific BE careful about the dead man… Interpretation of contingencies

12 Punishment???>>WRONG Before: Joyce receives no reprimands Behavior: Joyce goofs off After: Joyce receives a reprimand

13 Goofs off Large response class Does not pass dead man’s test

14 Avoidance Contingency Before: Joyce will soon receive a reprimand Behavior: Joyce studies After: Joyce won’t receive a reprimand soon

15 Escape vs. Avoidance Prevention vs. removal Avoidance: the response prevents an aversive condition from being received Escape: the response causes an aversive condition to be removed

16 Where does avoidance come from? What happens first?

17 Why is avoidance behavior resistant to change?

18 Avoidance following escape Before: Taste of hot sauce Behavior: Drink water, cough After: Reduce taste of hot sauce Before: You will soon have hot sauce After: You will not have hot sauce soon Escape Avoidance Behavior: “Please, no hot sauce”

19 Cued Avoidance Contingency Before: Buzzer is on Behavior: Rat presses lever After: Buzzer is off Before: Shock will come on in 3 sec After: Shock won’t come on in 3 sec Escape Avoidance

20 Establish a buzzer as a learned aversive condition buzzer No buzzerNo shock shock

21 Buzzer The neutral buzzer becomes a warning stimulus through use of the pairing procedure The pairing procedure brings into play the value altering principle

22 Continuous Response Avoidance Before: Sid will hear a click immediately Behavior: Sid maintains correct posture After: Sid won’t hear a click immediately

23 Noncued Avoidance Before: Shock will come on in twenty seconds Behavior: Rat presses the lever After: Shock will not come on in twenty seconds

24 Avoidance of Loss of a Reinforcer vs. Punishment by Removal of a Reinforcer Avoidance of Loss Contingency Penalty Involves the removal of a reinforcer Yes Removal is contingent on a specific response. NoYes Keeping the reinforcer is contingent on a specific response. YesNo The frequency of the response of interest IncreasesDecreases

25 Avoidance of Loss of a Reinforcer vs. Punishment by Removal of a Reinforcer Avoidance of Loss Contingency Penalty Involves the removal of a reinforcer Removal is contingent on a specific response. Keeping the reinforcer is contingent on a specific response. The frequency of the response of interest

26 Warning Stimulus vs. Discriminative Stimulus Warning stimulus –A stimulus that precedes an aversive condition and thus becomes a learned aversive stimulus Discriminative stimulus –A stimulus in the presence of which a response will be reinforced

27 Sdee Light is on After Shock won’t come on in 3 sec After Buzzer is off Behavior Rat presses lever Before Shock will come on in 3 sec Before (Warning stimulus) buzzer Sdelta Light is off After Shock will come on in 3 sec After Buzzer is on Behavior Rat presses lever Before Shock will come on in 3 sec Before (Warning stimulus) buzzer Escape Avoidance Extinction
