ABSTRACT
As more has been understood about dyslexia, with the acknowledgment that the dyslexic pattern varies between individuals, so there has been recognition that there are a number of other developmental differences of which dyslexia is only one. (Some theorists have used the term ‘developmental anomolies’, but we prefer the word ‘differences’ since we regard ‘anomolies’ as question begging.) Moreover, there is often some degree of overlap between them (see note 2.1).
