1. Schedule of reinforcement

   • Program or rule that determines which occurrence of a response is followed by the reinforcer
     • Ratio Schedule
       • Amount of responses
         • Fixed-ratio
           • Post-reinforcement pause
         • Variable ratio
       • Continuous reinforcement
       • Partial/ intermitent reinforcement
     • Interval Schedule
       • Time passed
         • Fixed interval
           • fixed-interval hop: increase in responding towards the end
         • Variable interval

2. Terms

   • Cumulative record
     • way of presenting repetition of response
   • ratio run
     • high+steady state of responding that completes every state of responding
   • ratio strain
     • w/ratio requirement increased a lot, likely to pause periodically
   • Limited hold
     • Restriction in time to get reinforcer
   • Delay discounting
     • Value of reinforcer declines the more you wait for it
   • Feedback function
     • how responses relate to reinforcement. behaviour only matters at certain times
   • Self-control
     • delaying immediate gratification for a greater reward later

3. Concurrent schedule

   • Two schedules are in effect at the same time & the animal is free to switch from one key to another
     • Relative rate of responding
     • Relative rate of reinforcement
     • The matching law
       • The relative rate of responding on alternative matches the relative rate of reinforcement on that alternative
         • response bias
           • reinforcer is not the same or effort is not the same
       • undermatching
       • Molecular maximizing
         • an organism always chooses the most likely to be reinforced at a given moment
       • Molar maximizing
         • an organism distributes its responses to maximize in the long run
       • Melioration
         • focuses on local rates of responding and reinforcement

4. Concurrent-chain schedule

   • Choice with commitment
     • Choice link
       • choice between 2 schedules
       • no reinforcement
     • Terminal link
       • stuck with that alternative until the end of a trial
