Lexical and sublexical analysis of single-word reading and writing errors
|
|
|

Abstract:
Within a dual-route neuropsychological model, two distinct but interrelated pathways are used to read and write, known as the lexical and sublexical routes. Individuals with reading and writing deficits often exhibit impairments in one or both of these routes, and therefore must rely on the combined power of the integrated system in print processing tasks. The resultant errors reflect varying degrees of lexical and sublexical accuracy in a single production. However, no system presently exists to analyze bimodal errors robustly in both routes. The goal of this project was to develop a system that simultaneously, quantitatively, and qualitatively captures lexical and sublexical errors for single-word reading and writing tasks. This system evaluates responses hierarchically in both routes according to proximity to a target. Each response earns a bivariate score [sublexical, lexical], which is plotted along x and y axes. This scoring system was developed using data from a novel treatment study for patients with acquired alexia/agraphia. Repeated-measures multivariate analyses of variance and post hoc analyses revealed a significant treatment effect in both the lexical and sublexical systems. Qualitative analyses were also conducted to evaluate patterns of change in both the trained and untrained modalities, in the sublexical and lexical systems. Overall, the results of this study indicate that treatment-induced evolution of reading/writing responses can be comprehensively represented by this novel scoring system. ; 2018-07-07T00:00:00Z
