Operant conditioning: Schedules of reinforcement | Behavior | MCAT | Khan Academy 

this video broke down the meanings of fixed Ratio, Fixed interval, Variable Ratio and Variable interval. Fixed Ratio is pretty much when a response is reinforced only after a specified number of responses. Fixed interval pretty much means being rewarded only after a specified amount of time has elapsed. Variable Ratio is reinforce after an unpredictable number of responses and Variable Interval is an inconsistent schedule (slot machine)

2:23 is where it starts if you're in a rush and just trying to get the MCAT definitions.

You do the most amazing job teaching the subject that I was confused about as a new potential RBT and pretty soon and March 2024 I will be taking the final RBT exam before I receive my job offer and I was confused and you did an excellent job breaking down. Explain it slowly and clearly piece by piece. Thank you.

thanks for helping me understand the schedules of reinforcement better

Thank u for this 💕

Great! So easy when you say it like this!

you really cleared this up for me it was frustrating af but now it's so easy Very helpful

I passed a quiz 10.79/15 but I was so mad because my professor did a horrible job at teaching this and the quiz mostly had questions that pertained to this. I wish I would have looked at this video before.

Thank great job

thanks thanks thanks

Jeffrey, thanks for the extremely helpful videos. Without wishing to offend, I'd like to point out something you do. Apparently, you haven't been adequately reinforced on the difference between 'number' and 'amount'. Incidentally, I accept the grammar rule only because it makes logical sense. For objects that can be counted, the term to refer to the quantity is 'number'; whereas, for objects that are not separable, and therefore not countable, the term is 'amount'. Whenever the object ends in an 's', the term 'number' is the appropriate one to use. I notice that you've used 'number' (standard) for the quantity of cars but 'amount' (nonstandard) for the quantity of responses. Since responses are separable into individual responses and can be counted 'response 1', 'response 2', 'response 3', etc., the term according to the standard grammar is 'number'. Think about how illogical it is to use the phrase "amount of responses" the way you'd use "amount of milk", and likewise how illogical to speak of "a number of water". The only way in which we might satisfy those calling themselves "descriptive grammarians" and "accept how people actually speak the language" would be to eliminate the word 'number' or accept 'number' and 'amount' as equivalent, the latter option resulting in redundancy. Accepting the first option, we might then speak of pi as an "amount that indicates the ratio of the amount of diameters to the amount of units in a circle" or of the "natural amount system of integers" or some such nonsense.

sadflksdf YOU MADE IT SO EASY!!!! THANKYOU!!!!!

Is that guy Donald trump KEK

at least talk with more enthusiasm please....

I was so confused after my professor taught this. But you've completely cleared it up. Thank you so much! Very helpful!!!

I've learned this several times over 2 years of a psych degree and it hasn't fully sunk in. My learning is set at a variable ratio level. If I keep attempting to learn, eventually I will hit the jackpot and the knowledge will remain in my head.

damn brother , you really cleared this up for me it was frustrating af but now it's so easy . thanks alot

He has no feet, he cannot engage with customers if he cannot walk, and doesn't have crutches or a wheelchair.

You messed up the interval schedule explanation. The response has to happen AFTER the interval has passed. If it happens before, no reinforcer is delivered.

This video is short and filled with key points. Thank you Khan Academy. You've made my informal education perfect.

Have an exam on this in 2 hours and these videos are absolutely awesome. Thank you so much for posting!!

I have an exam tomorrow about this topic, and your video really helps me to understand this topic. Thank you so much. 💗

pov i learn more in a 7 minute free video than i did all semester in a $2000 course

I have no feet and I must scream! (But I put on a smirky smile instead) I think your examples are inconsistent. Why did the condition change from selling cars to talking to customers? You should use accurately the same conditions in every model for the examples to be consistent.

I'm at the gym and remembered this for some reason

Fixed ratio- 1 behavior earns 1 treat Variable ratio- 3 behaviors is 1 treat, 2 behaviors is 3 treats 5 behaviors is 1 treat (casino effect) (most effective way to train any animal) Fixed interval- dog does the down for 10 mins and gets a treat exactly at 10 mins. Not ideal for dog training because the animal is more anxious as the amount of time passes. Variable interval- 3 mins of down is a treat, then 1 min of down is treat, then 5 min of down is a treat, then 20 seconds of down is a treat. (Ideal for training stay)

W khan academy for clearing this up.

Your example of a fixed-interval schedule is incorrect. In a fixed interval schedule, a fixed amount of time has to pass (in this case two weeks) AND THEN a response has to occur in order for reinforcement to be delivered. The amount of behaviour during that two-weeks time has no effect on whether the reinforcer is delivered. It is depended on time and then a response after the time. For this example to be true, the salesman would need to sell a car after the two weeks has passed in order to receive his paycheck. OR you could rectify this example by just using the paycheck without the cars being sold. Two weeks has to pass by, at the end of the two weeks, the paycheck becomes available at his/her place of employment. The behaviour is them picking up their check, but their paycheck will be in their hands after they pick it up and they can pick up the paycheck at any point after the two weeks. They can try to pick up their paycheck after 1 week, 9 days, 10 days, or 13 days, but the paycheck will not be given to them and these attempts do not alter whether the paycheck will be available.

Here is an example for Variable Interval; your car needs to get repaired but you don't know when exactly its going to be ready.

Amazing, this is so helpful. Thank you!

I'm a bit confused is this the same as continuous and partial reinforcement or completely different.

Thank you for this informative discussion, it really helps me a lot in my preparation for the upcoming March LET 2023. God bless and stay safe.

How would I go about writing this in in a paper ? My professior didn't explain :/

I'm still confused on variable interval reinforcement. Is it basically just random?

Great explanation!

Thanks Jeff, this definitely helped a lot!

One hour before my psych final 😅

I learned this to train dogs and just needed a little refresher. This was perfect

Really helpful first time I understand it, it is confuse sometimes 😢Thank you very much!! 😊

You guys explain everything SO well!! I wish my professor watched these videos before coming to class so she could teach these concepts much better!!

Why does he sound like he's in a dungeon

This is so helpful and explains the schedules way better than my textbook. Thank you!!

Mesej yang jelas, struktur yang jelas, mudah difahami, terima kasih

This has saved me! They all blurred into one until I watched this video... I am starting to finally get it! Thank you!

Thank you SO MUCH

can someone explain the difference between partial and continuous reinforcement ? i'm a little confused making it out

Useful👍 Tysm😃

tnx I understand the topic very well now stay blessed

Thanks you cleared it up for me

thank you so much I was very confused but now I understand it better!!!

Wow he even does psychology He really does know everything

SO helpful, thank you!

Thank you finally understood very helpful video ❤️

Thanks a lot !

cool video, bro!

thank you

Very helpful! Thanks

lucid

This was so helpful! Thank you!!

thx bro

Thank you !

Thankyou!

the avatar looks kinda like trump. he could do with some conditioning

I can confirm. Women train me on a variable interval schedule. Sometimes anecdotal evidence is data. :(

wow, really understood! thanks so much
