Short-term storage of repetitions of two items

Correct choice of the more frequent of two items presented in random sequence appears to be a function of the absolute, rather than the relative difference in number of repetitions of the items. When the absolute difference was held constant at one or five repetitions, proportions of correct choices remained constant as sequence length increased (and relative difference decreased), and was greater for an absolute difference of five than one. This suggests that such choice may depend on evaluation of the relative values of independent short-term traces for each item.
