Abstract

Spatial neglect is a neurocognitive disorder, affecting perception, representation, and/or motor planning. Neglect dyslexia in spatial neglect after right hemisphere damage (RHD) may co-occur with, or be dissociated from, other spatial neglect signs (Arduino, Daini, & Silveri, 2005; Lee et al., 2009; Vallar, Burani, & Arduino, 2010). Previous neglect dyslexia research focused on word-level stimuli and reading errors, primarily identifying letter omissions and substitutions to the left of the word midpoint (Ellis, Flude, & Young, 1987). However, functional materials may be more challenging to read (greater spatial extent of sentences and paragraphs, versus words). Although experimental studies that focus on reading at the single-word level may ask interesting theoretical questions regarding the sources of errors in the reading stages and systems, it is not often in the real-world that people read single words in isolation. We hypothesized that assessment materials with ecological validity such as reading a menu and reading an article would be more reflective of the degree to which reading errors and neglect dyslexia was detected in individuals with RHD than assessments that contained only single words or short phrases, which are rarely read in isolation in everyday life.
