Abstract

Impediments to lexical processing – concreteness effect and neighbourhood interference – were prioritised in the revision of a word list for individuals with surface or deep dyslexia. Psycholinguistic techniques were employed to recategorize 220 Dolch list words according to concreteness via function and content word categories, while including the associated orthographic, auditory and semantic neighbors of each word. We termed this revised word list as the High Frequency List of Similar Neighbors (HFLSN). One-way analysis of variance (ANOVA), Bonferroni post hoc test and Levene’s test of variance homogeneity were conducted. The HFLSN contains a total of 1057 neighbors across 5 function and content word categories, with effective delineation of concreteness value clusters between categories of lower variability.
