Myths about Dyslexia

?

Defining Dyslexia

  • DSM-IV defines it as a reading disorder
  • Rose Report (2009) - characteristics such as disorganisation, mental calculation etc are not themselves markers of dyslexia
  • Good comprehension, poor decoding
  • Discrepency definitions have issues - Children with a low IQ can't have dyslexia? Children who had poor literary teaching can't have dyselxia? Children from a lowere socioeconomic background less likely to have it? It has biological foundations so how would this impact these factors?
  • There are no good definitions, diagnosing it doesn't guide intervention, doesn't allow for causal explanation

Gift of Dyslexia

  • Ronald Davis claims it is a gift as it creates superiority in other aspects of life e.g. creativity, intuition, 
  • Malcolm Gladwell - desirable difficulty, suggests there is a link between entrepeneurs and dyslexia, they have difficult personalities making them better at business, no clear evidence for this
  • Shaywitz (2013) - sea of strengths model

Cures for Dyslexia

  • The DORE programme - focuses on the cerberal deficit hypothesis, physical exercise can cure dyselxia?
  • Coloured lenses
  • Fatty acids
  • Phonics - have actually been found to work, they develop phonological awareness and train relationship between letters and sounds, motivated by phonological deficit hypothesis

Evidence

  • Reynolds (2013) - found support for the DORE programme
  • Dorothy Bishop (2007) - heavily criticised the DORE programme and said it was not a cure
  • Alban, Adi and Hyde (2008) - coloured lenses are not a cure for dyslexia
