Training 'rule-of-<E>' : further investigation of a previously successful intervention for a spelling rule in developmental mixed dysgraphia

This paper reports a single case treatment study conducted with R.F.L., a young man with developmental mixed dysgraphia. The intervention focused on teaching spelling rules and was a replication of a previous successful study. The results of the present study provided further insights into the mechanism that operates to update faulty lexical representations for regular words. We argue that the level of spelling accuracy in combination with the error types present before the intervention are important to consider when choosing intervention methods.22 page(s
