Shaping | guides behavior toward closer and closer approximations of the desired behavior |
Discriminative Stimulus | Telling the difference between similar (but not identical) stimuli |
Continuous | Reinforce a behavior every time it occurs/ Learning occurs rapidly/ Extinction also occurs rapidly |
Partial | Reinforce a behavior some of the time/ More realistic/ Slower learning, slower extinction |
Fixed ratio schedules | reinforcement occurs after a set number of responses |
Fixed interval schedules | reinforcement occurs after a set length of time |
Variable ratio schedules | reinforcement occurs after an unpredictable number of responses |
Variable interval schedules | reinforcement occurs after an unpredictable length of time |
Fixed ratio schedules example | one free coffee after every 10 purchased |
