Drug Discrimination Protocol

Summary

---

• Includes three (3) protocols:
  • Food Shaping
  • Training
  • Testing
• Starts by turning on the left & right stimulus lights and house light
• Trial requires the animal to correctly respond with a lever to receive a reward, then time-out
• The program ends when the maximum number of rewards are earned or when the session time ends
• Totals for the whole program, as well as all data during each trial are collected (NOTE: SoftCR is also recorded)

Food Shaping

• Mimics a Fixed Ratio schedule
• The program starts by turning on the house light and both the left and right stimulus lights
• A trial consists of correctly responding on a lever to receive a reward, followed by a time-out
• The program ends when the maximum number of rewards are earned or when the session time ends, whichever comes first

Training

• Following an acclimation period, the program turns on the house light and both the left and right stimulus lights
• Responses on the correct lever result in a reward and turn off all lights, followed by an inter-trial interval
• Responses on the incorrect lever will reset the current fixed ratio
• The program ends when maximum number of rewards are earned or when the session time ends

Testing

• Following an acclimation period, the program turns on the house light and both the left and right stimulus lights
• Responses on either lever will result in a reward and turn off all lights, followed by an inter-trial interval
• The program ends when maximum number of rewards are earned or when the session time ends

Required Hardware:

• Med Associates operant chamber
