Acquisition
- behaviour is being learned/conditioned
Maintenance
- after it has become well learned
Response Rate
- number of instances of a behaviour – that occur in a period of time
Schedule of reinforcement
- rule specifying which occurrences of a given behaviour will be reinforced
CRF – continuous reinforcement
- each time you turn the tap, you get water
- best while in acquisition stage
- INTERMITTENT is best in the maintenance phase
Operant extinction
- opposite of CRF
Intermittent - BAD for extinguishing a response? But good for Establishing a response.
- advantages of CRF
- reinforcer remains effective longer – satitation takes place more slowly
- takes longer to extinguish
- individuals work more consistently on these schueldes
- more likely to persist in natural environment
4 types of intermittent schuedues
- ratio
- fixed-ratio FR
- occurs each time a fixed number of responses occur
- FR 2 – had to complete 2 math problems
- later 4 – F4

- increased in steps
- ratio strain
- deterioration of responding from increasing an FR too quickly (starting at F1)
- produces high steady rate until reinforcement
- followed by post-reinforcement pause
- the higher the value F 16 (instead of F2) the longer the pause
- piece-rate pay – farm worker paid for specified amount of fruit picked
- variable-ratio VR
- reinforced after certain number of responses
- number of responses changes unpredictably - around an average
- produces no post-reinforcement pause
- progressive-ratio PR
- ratio requirement increased by a specific amount after each reinforcement
- at beginning of each session – ratio requirement starts back at original value
- after a number of sessions – ratio requirement reaches break point - where
individual stops responding completely
- simple interval
- fixed-interval FI
- reinforcer presented following first instance of a response - after a period of time
- size of FI schedule
- the amount of time that must elapse before reinforcement becomes available
- you can respond right away or wait a day – you’ll be reinforced as long as it’s after the
set
time
- don’t always know when the fixed time is but if you generally know – responding increases
closer to
the time
- variable-interval
