Today:1) The Experiment
2) Operant Conditioning
3) The 5 Reinforcement Schedules we’ll use
4) Steps to completing the assignment
5) Grade Determination

The Experiment
![Page 4: Sniffy the Virtual Rat Psych 210 Winter Lab Assignment.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649d215503460f949f6923/html5/thumbnails/4.jpg)
Operant Conditioning
Increases the rate of a desired behavior by reinforcing that behavior when it occurs
In our case, we want Sniffy to bar-press
We will reinforce with food pellets
See Chapter 5 (B.F. Skinner) in your textbook
![Page 5: Sniffy the Virtual Rat Psych 210 Winter Lab Assignment.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649d215503460f949f6923/html5/thumbnails/5.jpg)
Operant Vs. Classical Conditioning
Operant (Type R):
Emphasis is on the Response
Use reward to increase a response
Classical (Type S):
Emphasis is on the Stimulus
Get a stimulus to elicit a response not normally paired with it
![Page 6: Sniffy the Virtual Rat Psych 210 Winter Lab Assignment.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649d215503460f949f6923/html5/thumbnails/6.jpg)
Schedules of Reinforcement-
2 Main Types:
Continuous Reinforcement (CRF):
Rewarded every time the desired behavior occurs
Every time Sniffy presses the bar, he will get a food pellet
Partial Reinforcement(PRF):
Rewarded some times when behavior occurs; not every time
e.g. Sniffy might press the bar 5 times and only get rewarded once.

PRF Schedules-Types:
Fixed:Reward happens after a set number of responses
“Fixed Ratio”
OR
after a set amount of time passes
“Fixed Interval”
Variable:Reward happens around a certain average number of responses
“Variable Ratio”
OR
after an average amount of time passes
“Variable Interval”

Fixed Ratio (FR):

Fixed Interval (FI):

Variable Ratio (VR):

Variable Interval (VI):

Saving your Progress:Saving properly is IMPORTANT for this lab!
THINK about what and how you are Saving each time
Always save to your H: Drive
Manual tells you when to Save and when to Print
As you are progressing through one step, save over the same file. So, throughout CRF training, keep saving as “CRF”. Once done, do NOT overwrite again.
![Page 15: Sniffy the Virtual Rat Psych 210 Winter Lab Assignment.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649d215503460f949f6923/html5/thumbnails/15.jpg)
Saving your Progress:You should save and print these files as you go:
“CRF” (documents Steps 1-3) – DO NOT SAVE OVER THIS FILE ONCE DONE THE ORIGINAL TRAINING!
“CRFext” (documents Steps 1-5) –*Print this*
“FR” (documents Step 6 –Training)
“FRext” (documents Steps 6- Training and Extinction) –*Print this*
“FI”, and then “FIext” (Step 7) -*Print this*
“VR”, and then “VRext” (Step 8) - *Print this*
“VI” and then “VIext” (Step 9) -*Print this*
