Dyslexia: the role of vision and visual attention

J Stein - Current developmental disorders reports, 2014 - Springer
Dyslexia is more than just difficulty with translating letters into sounds. Many dyslexics have
problems with clearly seeing letters and their order. These difficulties may be caused by …

The psychophysics of glaucoma: improving the structure/function relationship

RS Anderson - Progress in retinal and eye research, 2006 - Elsevier
Perimetry of some kind remains an important tool in the detection, diagnosis and monitoring
of glaucomatous damage to the visual pathway. However, recent studies have served to …

[HTML][HTML] Isolating the M (y)-cell response in dyslexia using the spatial frequency doubling illusion

K Pammer, C Wheatley - Vision research, 2001 - Elsevier
The contribution of M (y)-cell activity within a framework of a magnocellular-deficit theory of
dyslexia is currently unknown. Twenty-one dyslexic readers and 19 control readers were …

Predicting early reading skills from pre-reading measures of dorsal stream functioning

A Kevan, K Pammer - Neuropsychologia, 2009 - Elsevier
It is well documented that good reading skills may be dependent upon adequate dorsal
stream processing. However, the degree to which dorsal stream deficits play a causal role in …
