Watkins (1977) found memory span was longer when first and second halves of lists contained high- and low-frequency words, respectively, than when low-frequency words preceded high. One of the four experiments reported here failed to replicate this finding and found that articulatory suppression had a greater detrimental effect on span for high- than for low-frequency words. Another experiment showed that high-frequency words similar to those used by Watkins were easier to articulate than low-frequency words. In the third experiment articulatory suppression did not differentially affect delayed recall of high- and low-frequency words. The fourth experiment showed span for high- and low-frequency words was influenced in a similar way when encouraging subjects to maintain words from either early or late serial positions by articulatory rehearsal. It is concluded that differences in the strategies adopted to maintain words in the articulatory rehearsal loop can account for inconsistencies in the results obtained here and in previous experiments.
