Visuospatial deficits of dyslexic children.

Lipowska M, Czaplewska E, Wysocka A - Med. Sci. Monit. (2011)

Bottom Line: The results show that dyslexics experienced problems with visuospatial functioning, however only while performing difficult tasks.Significant group differences were found for the Clock Drawing Test, Spatial Span - Backward and the precision of figure coping in the Rey-Osterrieth Test.In addition, the results of dyslexic boys were lower than those obtained by all other groups.

ABSTRACT

Background: The visuospatial deficit is recognized as typical for dyslexia only in some definitions. However problems with visuospatial orientation may manifest themselves as difficulties with letter identification or the memorizing and recalling of sign sequences, something frequently experienced by dyslexics.

Material/methods: The experimental group consisted of 62 children with developmental dyslexia. The control group consisted of 67 pupils with no diagnosed deficits, matched to the clinical group in terms of age. We used the Clock Drawing Test (CDT), the Spatial Span subtest from the Wechsler Memory Scale - third edition (WMS - III), the Rey-Osterrieth Complex Figure Test in order to analyze visuospatial functioning.

Results: The results show that dyslexics experienced problems with visuospatial functioning, however only while performing difficult tasks. Significant group differences were found for the Clock Drawing Test, Spatial Span - Backward and the precision of figure coping in the Rey-Osterrieth Test. In addition, the results of dyslexic boys were lower than those obtained by all other groups.

Conclusions: Our findings provide support for the hypothesis concerning visual deficit as characteristic for dyslexia.

f1-medscimonit-17-4-cr216: Comparison of results in the Rey-Osterrieth Complex Figure Test.

Mentions: First of all we compared the results obtained by children with dyslexia and children from the control group in the particular tests which measured the level of visuospatial capacity. According to our expectations concerning the Rey-Osterrieth Complex Figure Test, in which a child had to copy a complex figure, demonstrated on the picture – first when looking at it, and then after memorizing it – children with reading difficulties obtained lower results when copying (t=3.8; p=0.000) (Figure 1).
