Extinction Study Flashcards

App Preference Assessment

  1. “[Participant’s Name], here’s an ipad with games, you can take some time to get familiar” (30 seconds) 

  2. “[Participant’s Name], please rank your top 6 preferred apps, with 1 being your highest”

  3. Remove sheet.

Phase 1: (Orange) Button 1 is assigned to HQ4, the TARGET response.          Tally: 

        (Blue) Button 2 is assigned to HQ1, the ALTERNATIVE response.   Tally:

  1. Present two buttons: “If you press this button (b1), you will get [top 2 apps], if you press this button (b2), you will get an ipad with no apps.”

  2. Participant presses a button, and the researcher allows access for about 30 seconds. 

  3. Continue trials until the participant reaches 3 consecutive responses towards the target button.

  1. If the participant does not make a response within 30s, provide the prompt stated in step 1.

  2. If 3 consecutive responses are not made by participant in the first 3 trials, researcher continues phase 1 until:

  • 3 consecutive responses are made OR

  • The participant makes 5 target responses out of 9 trials, and the researcher moves to phase 2.

Phase 2: (Orange) Button 1 is assigned to HQ1, the ALTERNATIVE response.      Tally: 

    (Blue) Button 2 is assigned to HQ4, the TARGET response.             Tally:

  1. Present two buttons: “Okay, something different is going to happen. If you press this button (b1), you will get an ipad with no apps, if you press this button (b2),you will get [top 2 apps].”

  2. Participant presses button, researcher allows access for 30s. 

  3. Researcher repeats steps 1-3 until participant reaches 3 consecutive responses towards the target button. 

    1. If the participant does not make a response within 30s, provide the prompt stated in step 1.

    2. If 3 consecutive responses are not made by participant in the first 3 trials, researcher continues phase 2 until:

  • 3 consecutive responses are made OR

  • The participant makes 5 target responses out of 9 trials, and the researcher concludes assessment.





Forced Choice

B1 Target Response Button = HQ4 and  B2 Alternative Response Button= HQ4

  1. Researcher Presents both buttons and says “Touch this button” and points to it. Participant touches the button. Researcher delivers HQ4 ipad for 30s, “My turn”

  2. Researcher immediately says “Touch this other button” and points to it.Participant touches the button. Researcher delivers HQ4 ipad for 30s, “My turn”.

  3. Researcher moves onto the Quality degradation phase.





Quality Degradation Phase

Researcher will run degradation protocol until the participant goes through all of the quality degradations OR engages with the alternative response for 5 consecutive responses.

Target Response = HQ4 iPad. Tally:   

Alternative Response = FR1+ HQ4 ipad. Tally:

  1. Researcher presents both buttons and says “Pick a button”. 

  1. If the participant does NOT make a response within 30s, provide a prompt again, “Pick a button”. 

  2. If participant picks the target button, participant gets access to HQ4 iPad for 30s.

  3. If participant pick the alternative button, the researcher requires the participant to complete one math problem (FR1) to get access to HQ4 iPad for 30s.

i. Researcher verifies the completion and of participant’s response to math problem.

ii. If the participant does NOT make an accurate response, the researcher says “Try again”.         

-If the participant is still wrong, offer them the correct answer and allow them access to 

The HQ4 iPad.

   2.  Researcher repeats step 1 until participant engages with the same button whether it be 

target or alternative) for 5 consecutive responses, or 5 of 9 trials.

           3. Researcher moves onto the next HQ degradation.

  1. If the participant does NOT make a response within 30s, provide a prompt again, “Pick a button”. 

  2. If participant picks the target button, participant gets access to HQ3 iPad for 30s.

  3. If participant pick the alternative button, the researcher requires the participant to complete one math problem (FR1) to get access to HQ4 iPad for 30s.

i. Researcher verifies the completion and accuracy of participant’s response to math 

problem.

ii.If the participant does NOT make an accurate response, the researcher says “Try 

again”.         

If the participant is still wrong, offer them the correct answer and allow them access to 

the HQ4 iPad.

  1. Researcher repeats step 1 until participant engages with the same button for 5 consecutive responses, or 5 of 9 trials.

  1. If the participant makes 5 consecutive responses to the alternative, the researcher reverses back to Phase A. 

i. Researcher goes through steps in HQ4 phase until complete.

ii. Researcher returns back to HQ3 phase until complete. 

  1. Researcher moves onto Progressive Ratio if participants make 5 consecutive responses to the alternative again. 

  1. If the participant makes 5 consecutive responses to the target, the researcher moves onto the next HQ degradation.

  1. If the participant does NOT make a response within 30s, provide a prompt again, “Pick a button”.

  2. If participant picks the target button, participant gets access to HQ2 iPad for 30s.

  3. If participant pick the alternative button, the researcher requires the participant to complete one math problem (FR1) to get access to HQ4 iPad for 30s.

i. Researcher verifies the completion and accuracy of participant’s response to math problem.
