Variable Schedule Protocol Package

Summary

---

• Through a series of LIST statements the user may select between the following schedules to run:
  • Fixed Ratio (FR), Fixed Interval (FI), Variable Ratio (VR), Variable Interval (VI)
• For each trial there is a preCS and a CS (conditioned stimulus) period
  • Both periods are always the same length
  • The correct response(s) on the correct lever during either period gives a reward
  • There is no reward given during the Inter-Trial Interval (ITI) or the pre/post adapt periods
  • Any responses during the preCS period are discarded when the CS period starts
  • Example: If the program is running an FR-10 schedule and the animal has four responses when the program switches to the CS period, the four responses are discarded and the animal must start over to meet the FR-10 schedule. The same schedule is run during the preCS and CS periods

Variable defaults

• Number of Trials = 10
• Pre Adapt Period = 240 sec
• Post Adapt Period = 180 sec
