Note: Standard scores are based on a mean of 100 and a standard deviation (SD) of 15. Note: Acronyms are as follows: WRMT for Woodcock Reading Mastery Test – Revised NU; TOWRE for Test of Word Reading Efficiency. Note: Participants completed either the Kaufman Brief Intelligence Test (KBIT) (8 control; 8 dyslexic) or the Wechsler Abbreviated Scale of Intelligence (WASI) (5 control; 3 dyslexic) for Performance IQ; and either the CTOPP Rapid Letter Naming (10 control; 7 dyslexic) or the RAN/RAS Letter subtest (3 control; 4 dyslexic) [108] . Rapid Letter Naming scores are based on z scores to allow for comparison between different subtests used.
