Forty Naval Postgraduate School students participated in a verbal discrimination (VD) experiment using ti.ree-word items of different frequency ratios „ Half of the three-word items were composed of similar words and half, dissimilar words. Based on information tneory the words were grouped into two lists, both of equal length and approximately equal information,, Perfoimance by the subjects showed statistical significance for the trial and item similarity main effects and for the test by item similarity interaction. The effect of using different frequency ratios within the separate word lists showed a facilitation of learning only for items with similar words „ Apparently, the differential ratios were not sufficiently apparent in the dissimilar items to permit the use of preexperimental frequency differences as a cue to learning.
