ABSTRACT
BACKGROUND/AIMS:
There is an increasing recognition that visuocognitive difficulties occur in children with neurodevelopmental problems. We obtained normative data for the performance of primary school children using three tests of visuocognitive function that are practicable in a clinical setting.METHODS:
We tested 214 children aged between 4 and 11â years without known developmental problems, using tests to assess (1) orientation recognition and adaptive movement (postbox task), (2) object recognition (rectangles task) and (3) spatial integration (contours task).RESULTS:
96% could do the postbox task with ease-only 4% (all aged <9â years) exhibited minor difficulties. Errors in the rectangles task decreased with age 33% of children aged 4-5â years had major difficulties but >99% of children aged ≥6â years had no, or minor, difficulties. Median scores for the contours task improved with age, and after age 8â years, 99% could see the contour using long-range spatial integration rather than density.CONCLUSIONS:
These different aspects of children's visuocognitive performance were testable in a field setting. The data provide a benchmark by which to judge performance of children with neurodevelopmental problems and may be useful in assessment with a view to providing effective supportive strategies for children whose visuocognitive skills are lower than the expectation for their age.Palavras-chave
