Definition

Paralexia: It is an error made during reading by persons with an acquired reading disorder known as either alexia or acquired dyslexia. Alexia is not a sensory deficit, that is, the deficit is not related to a disturbance in visual acuity or visual field. Types of paralexic errors have been described based on reading models and are associated with the types of peripheral alexia (pure alexia, visual alexia, attentional alexia, neglect alexia) and types of central alexia: phonological alexia, surface alexia, and deep dyslexia (Benson and Ardila 1996; Newcombe and Marshall 1986; Riley and Kendall 2013). Patterns of paralexic errors exist and assist in distinguishing among these alexias. Some general categories of paralexic error types include phonological, semantic, visual, morphologic, and derivational. Phonological paralexias are errors in which the response typically sounds like the target word (e.g., sequins → sequence). Semantic paralexias are errors that are similar in...
