Abstract
THERE have been many experiments in which the limited channel capacity of the human organism has been demonstrated by interference between two simultaneous tasks1. Brown2 used this interference of a secondary task as a measure of the difficulty of a primary perceptual or control task; and in a recent study3 he used a cognitive secoridary task. The experiment described here was devised to investigate the effect of a secondary verbal task on a primary cognitive one.
