When 'slime' becomes 'smile': Developmental letter position dyslexia in English

► This study presents the first three cases of letter position dyslexia in English. ► Cardinal symptom: migration of letters within the word (reading slime as 'smile'). ► Letter position dyslexia (LPD) is caused by a deficit in letter position coding. ► Migration errors are not caused by poor phonological processing or a lexical deficit. ► The performance in English LPD resembles the patterns found for Hebrew and Arabic.
