Triadic Learned Helplessness Protocol

• Designed to simultaneously run three animals in individual boxes
• Subjects in the escape condition learn to turn the response wheel to terminate the aversive stimulation for themselves and a yoked partner (control subject is not shocked)
• On load:
  • Left = escape
  • Center = control
  • Right = yoke

NOTE: If your system has aversive stimulators in all three positions, the code may be modified to randomly select conditions

Default variables

• Trials to run = 100
• Session time = 360 min
  • NOTE: session is closed if either condition is met
• Maximum aversive stimulation time = 30 sec

Seven columns of data for each trial:

• Trial Number
• Left Response Counts
• Center Response Counts
• Right Response Counts
• Time to Meet FR
• FR Value
• ITI Value
