Sixty Naval Postgraduate School students served in a verbal discrimination VD experiment with 2-, 3-, and 4-word items at presentation rates of 12 or 14 bits of information per second. 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 was observed because of the rate factor. Analysis of percent correct responses revealed a significance for the item length main effect which was at variance with the null hypothesis of no difference borne out by the information analysis.
