Four-sight in hindsight: The existence of magical numbers in vision
Published online by Cambridge University Press: 30 October 2001
Abstract
The capacity of visual attention/STM can be determined by change-detection experiments. Detecting the presence of change leads to an estimate of 4 items, while detecting the absence of change leads to an estimate of 1 item. Thus, there are two magical numbers in vision: 4 and 1. The underlying limits, however, are not necessarily those of central STM.
