Assignment 4 Name(s):
1. Shaping:
Working with a family member, roommate, or friend, use shaping to get them to do the following two behaviors.
1. Touch nose with left hand/finger
2. Stand up on a chair/sofa/etc.
The listed behaviours are the “target behaviours,”…you have to decide which approximation of the behaviour you are going to start reinforcing, then apply extinction to see if the extinction burst brings out a behaviour that is even closer to the target behaviour. Document (describe) what happened for each attempt, including behaviours reinforced, the reactions of the other person, whether or not they were successful and how long the process took. In order to shape them, you can use the word “yes” if they are doing the approximation you want, or silence – no additional prompts! It’s harder than it would seem. Make sure you record all behaviours tried and whether you reinforced or extinguished them.
Read these instructions to your friend (after that…no hints! Only yes or silence):
I’m going to try to get you to do a certain behaviour, but can’t tell you what it is. If you are doing something that is close to what I’m looking for, I’ll say yes. If you aren’t close, I will be silent. All I ask is that you do a variety of movements with your body so I can find a place to start reinforcing you.
2. Print out a T-puzzle, cut it using the guidelines into 4 pieces, and go out and find one person to try it . You can give the person the following instructions: Use these four pieces to make a capital letter “T”. Make detailed observations about the following:
a. Describe the first strategy they tried…in as much detail as possible.
b. How many times did they try that strategy, or another strategy, within the first minute of
trying to solve the puzzle?
c. Did the person exhibit any frustration, anger, etc. while solving the puzzle? How can that
emotionality be explained in behavioural terms?
d. Was the person able to solve it? How much time did it take them?
e . Did they do a lot of puzzles in their childhood? Adulthood?
f. Describe the entire event in terms of variation, selection and retention, defining the prepotent response.
