Mixed Lateral Dominance as a Predictive Factor of Learning Disability.
Powers, P. J.; Putnam, Jon
This report discusses the outcomes of a study of 147 children (ages 7-10) with learning disabilities that investigated the extent to which students legally classified with learning disabilities concurrently manifested mixed lateral dominance (MLD). The study was conducted to determine if MLD was a possible predictive factor for early identification of learning disabilities. The learning disability classification of the subjects included individual performance, verbal, and full-scaled IQ scores. Also included were performance, visual, and Sigma-scaled raw scores. MLD was then measured using the Dennision Laterality Test in all subjects to determine if subjects manifested their perceptual motor or neurological characteristics concurrently with learning disabilities. Results of the study appear to support the heterogeneity of learning disabilities, especially in the pursuit of a simple predictive factor that was significantly associated with early, simple screening and identification of learning disabilities.
