Effects of Temporal Sequencing and Auditory Discrimination on Children's Memory Patterns for Tones, Numbers, and Nonsense Words

Abstract

The purpose of this study was to determine whether children's recall of tones, numbers, and words was supported by a common temporal sequencing mechanism; whether children's patterns of memory for tones, numbers, and nonsense words were the same despite differences in symbol systems; and whether children's recall of tones, numbers, and nonsense words was related to their aural discrimination ability. Participants ( N = 74) were children enrolled in grades 1 through 3, drawn from an urban magnet school. On the basis of U-shaped performance profiles, the authors concluded that a common temporal sequencing mechanism may undergird children's recall of tones and nonsense words; thus, these domains may be linked at some basic level. Based on intraclass correlations that compared children's patterns of memory for tones, numbers, and nonsense words, the authors found that children's memory for information varied by symbol system and according to the characteristics of patterns within each symbol system. Finally, they found that aural discrimination skill contributed to children's recall despite differences in symbol systems.
