Studies on primitive and postural reflexes
2001 - A study was undertaken by Goddard Blythe SA which examined Neuro-developmental factors in 54 children who had received an independent diagnosis of dyslexia. All participants displayed evidence of abnormal ATNR and TLR, together with other Neuro-developmental factors.
The Institute for Neuro-Physiological Psychology conducted a study in Ireland and Germany in 2003/4, and found that between 35 and 48 percent of children in regular school programmes and up to 100 percent of children in special education programmes showed signs of primitive reflex retention.
1976 - University of Purdue. Bender examined the effect of one reflex - the STNR on education - and found it present in 75% of a group of learning disabled children but was not present in a comparison group of children with no history of learning disabilities.
1971 - University of Kansas Rider (OT) assessed the prevalence of abnormal reflex responses by comparing normal second grade children to a group of learning disabled children. Children with normal reflexes scored consistently higher on achievement tests than those with abnormal reflexes.
