Abstract: | Let > 0 be a measure of the average step size of a stochastic process {pn() }n=1(). Conditions are given under whichpn() is approximately normally distributed whenn is large and is small. This result is applied to a number of learning models where is a learning rate parameter andpn() is the probability that the subject makes a certain response on thenth experimental trial. Both linear and stimulus sampling models are considered. |
