Recently, it has been reported that primacy and recency effects are obtained in repetition of individual syllables within nonwords (Gupta, in press). Five experiments examined whether such within-nonword primacy and recency effects are attributable to common sequencing mechanisms that are shared with immediate list recall. Experiments 1 and 2 indicated that the primacy and recency effects are not simply due to greater morphological salience at the beginnings/endings of nonwords, and that the serial position effects generalize to different stimuli and across a variety of stimulus lengths. Experiment 3 indicated that the primacy and recency effects are similar to those obtained in list recall. Experiments 4 and 5 examined alternative hypotheses for the observed serial position effects, concluding that the alternative hypotheses fail to account for the obtained pattern of results. These results provide support for the common sequencing mechanisms hypothesis. The implications of these results are discussed in terms of the relationship between list recall and nonword repetition, and in terms of broader issues in word learning.
