Abstract
Sixty Naval Postgraduate School students served in a
verbal discrimination (VD) experiment with 2-, 3-, and
4-word items and presentation rates per item of 1.5 or 3.0
seconds. Half the items had similar and half, dissimilar
words. Based on information theory, lists of different
lengths were prepared for 2-, 3-, and 4-word items. The
lists were equated for overall load at 20 bits of information.
Performance was consistent with the equal-load
hypothesis and a differential of two in the amount of
information transferred was observed because of the rate
factor. Analysis of variance of correct responses revealed
significant effects for item length, presentation time,
similarity, and trials.
