The Four Schedules of Reinforcement in Behaviorism

This video describes the four reinforcement schedules from behavior therapy. The terms fixed (every n times or n amount or time) and variable (variable number of responses or variable amount of time) are combined with ratio (based on the number of responses) and interval (based on time) to generate the four schedules. A Fixed Ratio system of reinforcement schedule reinforces every nth response. Fixed Ratio schedules are ideal for optimizing quantity over quality. A Fixed Interval reinforces every n amount of time. Fixed Interval schedules are ideal for optimizing quality over quantity. Variable Ratio schedules reinforce at a varying number of responses. Variable Interval schedules reinforce at varying amounts of time. Fixed schedules are easy to extinguish and easy to learn. Variable schedules taking longer to learn and are more resistant to extinction.

I got a clear understanding of the reinforcement schedules. The examples brought more clarity

Nice clear explanation of reinforcement schedules. I especially appreciate the examples as they help to conceptualize the abstract ideas.

This was far better than reading my textbook

[@virginiamurrey9139]

I had not quite grasped this concept previously when reading a textbook. This video was very helpful on explaining this concept.

Love the life examples used for all reinforcement schedules. Made the video easy to understand.

I appreciate the examples provided for the explanation of each schedule.

Hi. Dr. Grande! I'm a Ph.d student from South Korea. I have a question on one of your past videos regarding statistics but I was worried if you might not see the comment there. I apologize for commenting on an irrelevant video. I found your video on two-way repeated anova really helpful. But I was hoping to ask you if applying a series of t-tests after 2 way repeated anova violates the Type 1 error. Is it just...okay for repeated two way anova? if so, could you explain why? T_T... Is it possibly the case that post hoc tests for repeated 2way anova do simply not exist ? or it exists but repeated paired-samples t-tests provide a richer information or something? Thank you!

Thanks!

Great Lesson. Got a T-shirt :)

[@DrGrande]

Thank you so much :)

Not much to add, other than this was a clear summation of reinforcement schedules.
