Abstract
Subjects were required to make intuitive estimates of the means of samples of 10 or 20 numbers presented in visual arrays. In Experiment 1 presentation times were varied together with sample size in order to keep the information processing rate constant. In Experiment 2 sample size was kept constant as presentation time varied. Accuracy of Ss’ estimates decreased when either informational load or rate increased.
