M-Cell Deficit and Reading Disability: A Preliminary Study of the Effects of Temporal Vision-Processing Therapy

Assessment | Middle School

Summary of Findings:

The study involved 16 seventh-grade students from a New York City school who were defined as moderately disabled readers after being tested on the Gates-MacGinitie Reading Test.

Results showed significant improvement on all post-tests, with the Gates Test (p=0.001) average GE increase to 6.52, and the Coherent Motion Threshold Test (p=0.011) down to 4.98%. The students’ average w.p.m. increased to 160 on the Gray Oral Reading Test (p=0.002) and the students achieved a 11.19 mean scaled score increase on the Woodcock-Johnson Test (p=0.001). This study concludes that through temporal vision therapy, reading disabled students with M-Cell deficit can improve magnocellular processing and reading comprehension skills.

“Eye movements in reading, measured objectively with the Visagraph, can be improved significantly with appropriate therapy.”
