Auditory Memory and Visual Memory in Typically Developing Children: Modality Dependence/ Independence.

Abstract

The study aimed to determine whether there was a difference or an association between auditory memory and visual memory in typically developing children. Eighteen children, aged 8 to 12 years, with normal hearing and visual acuity, were evaluated using the Children's Memory Scale (CMS) to determine their auditory and visual memory performance. Using the core subtest battery of the CMS, auditory/verbal (immediate and delayed), visual/nonverbal (immediate and delayed), and general memory index scores were assessed. No significant difference was found between auditory/verbal memory and visual/nonverbal memory scores for both immediate and delayed recall. Likewise, no correlation between auditory/verbal memory and visual/nonverbal memory scores was found. However, there was a significant correlation between immediate and delayed recall scores within each modality. The non-significant difference between the two modalities for both immediate and delayed recall gives the impression that memory is modality independent. However, the lack of any correlation between the two suggests there was no association between them. The absence of a significant difference between modalities can be attributed to the auditory and visual test material used in CMS not being analogous. It can thus be inferred that the auditory and visual modalities are independent. While the visual material evaluates simultaneous/concurrent perception, the auditory material assesses sequential perception.
