In my review of the book "Why children can't read" (TES, June 11), I mistakenly stated that the author, Dr Diane McGuinness, developed the Phono-Graphix (trademark) materials which she recommends.

In fact, as the book makes clear, Phono-Graphix was developed by Geoffrey and Carmen McGuinness (Diane McGuinness's son and daughter-in-law). Many apologies for my mistake.
