Schedules of Reinforcement
Is there more than association to learning?
How important is control to psychological health?
How can conditioning help us treat psychological disorders?
Can reinforcement be delayed?
But most effective if presented immediately
Notion of operants
Response-reinforcement bond is critical... response that get reinforced are more

Schedules of reinforcement
1. Continuous reinforcement --> CR
Reinforce every correct response
1. Fixed Ratio --> FR
Reinforce every nth correct response
FR5 --> reinforce every 5th correct response ---> FR 1 = CR
1. Variable Ratio --> VR
On average, reinforce every nth correct response
1. Fixed interval --> FI
Reinforce first correct response after a certain time has elapsed
e.g. FI 1 minute, reinforce first correct response after 1 minute
1. Variable interval --> VI
Reinforce first correct response after a certain time has elapsed on average
Partial Reinforcement Effect
Experience with “extinction” maintains responding because reinforcement is
Partial better than continuous
VR or VI are most resistant to exti
