Variable interval vs Variable ratio - extinction

[vashappenin]

Extinction-
V.R
F.R
V.I
F.I

For establishing response
F.R
V.R
F.I
V.I


But all in all the main thing really is the first ones
Variable ratio is always going to be least resistant to extinction and highest rate or responding

Do you mean most resistant?
What are you referring to when you say 'establishing response'  (acquisition or rate of responding?)?

Well as Variable ratio is an effective means of delivering punishment is it likely that undesirable  behaviour will decrease. Its bassically just a punishment question

Oh sorry how stupid of me yep most resistant.
Yep acquisition

The schedules are only valid for reinforcement, not punishment, aren't they?

What about this one.. I interpreted it as continuous, but solutions say variable-ratio OR variable-interval...

A waiter who receives a share of tips left by diners is being reinforced according a ______________ reinforcement schedule.

 

[Oliver_123]

Well anyway A is only logical answer as it is punishment

[Oliver_123]

Its not guaranteed that customers will leave tips every time is it? So it is variable, as it would fluctuate in respect to both time and number of people is you get me?

Question 16
Tam punishes her cat's scratching of the sofa on a variable-ratio schedule.
Which of the following is least likely?
A. The frequency of the cat's undesirable behaviour will decrease.
B. The frequency of the cat's undesirable behaviour will increase.
C. The cat will become frightened whenever Tam comes near.
D. The cat will stop scratching the sofa but will start to scratch the carpet.

The answer is A.

Well anyway A is only logical answer as it is punishment

But..the question said Which of the following is least likely? :/

The solutions make sense. A waiter isn't usually left tips from every time a diner comes in, so it wouldn't be continuous.

Edit: Oops, my answer came too late. See above

Yeah I didn't think it through at the time, thanks

They are just for reinforcement.

Why would Fixed-ratio be the second most resistant to extinction, as two of the posts on the first page seem to suggest? Surely a response under fixed-ratio would extinguish quickly.

INITIALLY, it's the most resistant to extinction, before its overtaken by variable ratio. I can't think of a reason why ~ that's just how it is (what the textbooks say).

But after that then I thought it had little resistance to extinction, with variable interval being slower to extinguish. (I assume I got this information from Grivas).

Been to lectures, and from past exams as learning has been on exams for ages, variable ratio is deffinitely most resistant to extinction
