RR(10) means that the average winning responses over a large amount of responses should be 1 in 10 but can occur unpredictably where as by VR there is a predetermined upper limit
Can you actually give me an example?? I don't get how in RR, the responses occur "independantly of each other"
Okay, so for a Variable Ratio, there has to be an average that reinforcement is given in. So, if the ratio is set at 1 x Reinforcement for an average of 50 responses and you do one response and get the reinforcement straight away, you might try another 99 responses before you get more reinforcement, which would mean you got 2 x Reinforcement for the 100 responses. Thus, the average is 50. In this scenario, the reinforcement is dependent on previous reinforcement. Eg, if on your first response you got reinforcement, and you're about to do your 98th response, then there is an extremely high likelihood that you will get reinforcement for the next response, as the average of 50 has to be kept, and there hasn't been reinforcement for the previous responses. So = dependent.
A Random Ratio is literally random. There is no average reinforcement to meet. So, if there is a 1 out of 1,000,000 chance that you will get reinforcement for a response, then that does not mean that if you give that response 1,000,000 times then you will receive reinforcement. Because for EACH INDIVIDUAL RESPONSE, the chances are the same and not
dependent on anything else, so they are
independent of each other.
