A matter of emphasis: Linguistic stress habits modulate serial recall.

Taylor JC, Macken B, Jones DM - Mem Cognit (2015)

Bottom Line: Models of short-term memory for sequential information rely on item-level, feature-based descriptions to account for errors in serial recall.However, in two experiments, we demonstrated that the characteristics of the sequence are what determine the fates of items, rather than the properties ascribed to the items themselves.Performance in alternating sequences is determined by the way that the sequences themselves induce particular prosodic rehearsal patterns, and not by the nature of the items per se.

ABSTRACT
Models of short-term memory for sequential information rely on item-level, feature-based descriptions to account for errors in serial recall. Transposition errors within alternating similar/dissimilar letter sequences derive from interactions between overlapping features. However, in two experiments, we demonstrated that the characteristics of the sequence are what determine the fates of items, rather than the properties ascribed to the items themselves. Performance in alternating sequences is determined by the way that the sequences themselves induce particular prosodic rehearsal patterns, and not by the nature of the items per se. In a serial recall task, the shapes of the canonical "saw-tooth" serial position curves and transposition error probabilities at successive input-output distances were modulated by subvocal rehearsal strategies, despite all item-based parameters being held constant. We replicated this finding using nonalternating lists, thus demonstrating that transpositions are substantially influenced by prosodic features-such as stress-that emerge during subvocal rehearsal.

Mentions: These impressions were confirmed statistically. Transposition errors were collapsed across input–output positions, allowing for the comparison of errors rates as a function of transposition distance (Fig. 9).Fig. 9
