Poor spellers with good phonetic skills more likely to be right-handedMay 30th, 2008 - 2:04 pm ICT by admin
Washington, May 30 (ANI): Kids who have good phonetic skills the ability to recognize the individual sounds within words but arent so go when it comes to spelling those words, are more likely to be right-handed than other poor spellers, says a new study.
The three-year study, which has been published in the May 2008 issue of Cortex, was carried out in a cohort of children drawn from normal schools.
The children attended nine different schools regarded as representative of the local education authority, including both town and country districts.
In the first year of study all children in the 9-10 year age group were screened for laterality, literacy and cognitive abilities using short group tests (hand skill, spelling, non-word spelling, drawing shapes and homophonic word discrimination).
Tests requiring individual examination, including reading, were given in Year 2. In the end 414 children were available for the spelling analyses in Year 1, of whom 324 were tested further in Year 2.
The results of the study show that poor spellers with good phonetic equivalent spelling errors (GFEs) included fewer left-handers (2.4percent) than poor spellers without GFEs (24.4 percent). Differences for hand skill were as predicted.
These findings support the right shift theory of handedness and cerebral dominance, which predicts that dyslexics with good phonology would be strongly right-handed, says Marian Annett, researcher at the School of Psychology of Leicester, UK and corresponding author of the paper. (ANI)
