Phonological Similarity and Trace Degradation in the Serial Recall Task: When CAT helps RAT,but not MAN

Phonological similarity is observed to affect serial recall detrimentally when correct-in-position scoring is used. Two experiments investigated the role of item and position accuracy scoring of rhyming, similar nonrhyming, and dissimilar lists under immediate recall conditions; articulatory suppression; or a filled delay. In general, rhyme lists produced the best item recall but position accuracy was highest for dissimilar lists. The results are due to a category cueing effect improving item recall for rhyme lists in conjunction with a detrimental effect of phonological similarity on position accuracy.
