  • Title: Mental imagery and dyslexia: a deficit in processing multipart visual objects?
    Author: Koenig O, Kosslyn SM, Wolff P.
    Journal: Brain Lang; 1991 Oct; 41(3):381-94. PubMed ID: 1933264.
    Abstract:
    Dyslexic and normal control subjects memorized simple line patterns inside a grid and subsequently judged whether an "X" would have fallen on the pattern had it been present in an empty grid. The patterns were letters and novel shapes. The grids were presented to the left visual field, to the right visual field, or in central vision. Dyslexic subjects had difficulty generating images of multipart patterns, but this deficit was limited to letters. The findings suggest that dyslexics may have selective difficulty integrating visual information stored in long-term memory.
