Visual perception, visual-spatial cognition and mathematics: Associations and predictions in children with cerebral palsy.
Visual perception and language comprehension drive math success in kids with CP—check both before teaching numbers.
01Research in Context
What this study did
Critten et al. (2018) compared kids with cerebral palsy to typically-developing peers. They looked at how vision, space skills, and language link to math scores.
The team used puzzles, picture tests, and math worksheets. All kids were between 8 and 14 years old.
What they found
Children with CP scored much lower in math and visual-spatial tasks. Visual perception and receptive vocabulary were the strongest predictors of math success in the CP group.
In plain words: if a child could spot small details in pictures and understand spoken words, math went better.
How this fits with other research
Dionne et al. (2024) saw the same pattern in kids with Developmental Coordination Disorder. Visual-perceptual skills again predicted math struggles, showing the link is not just a CP quirk.
Allen et al. (2016) widened the lens. They found that preterm and low-birth-weight children also fall behind in visual-cognitive skills, and this hurt both reading and math. The CP study narrows the focus to math alone.
Kanevski et al. (2023) looked at ADHD plus movement issues. They found weaker visuospatial working memory yet normal math scores. This seems to clash with Valerie’s results, but the difference is the skill measured: working memory versus pure visual perception. Kids may use memory tricks to keep math afloat even when perception is shaky.
Why it matters
Before you teach math to a child with CP, screen visual perception and receptive language first. Quick picture-discrimination tasks and simple vocabulary checks take five minutes and tell you if extra visual supports or language previews are needed. Pair word problems with clear, uncluttered images and check that directions are understood. These small tweaks can prevent later frustration and boost learning speed.

03Original abstract
BACKGROUND: Previous research suggests that children with cerebral palsy (CP) have impairments in visual-spatial and mathematics abilities, although we know very little about the association between these two domains. AIMS: To investigate the extent of visual-spatial and mathematical impairments in children with CP and the associations between these two domains. METHOD AND PROCEDURE: Thirty-two children with predominantly quadriplegic spastic and/or athetoid (dyskinetic) CP (13 years 7 months) and a group of typically developing (TD) children (8 years 6 months) matched by receptive vocabulary were given a battery of visual-spatial and mathematics tasks. Visual-spatial assessments ranged from simple tests of perception to complex reasoning about these stimuli. A standardised test of mathematics ability was administered to both groups. OUTCOMES AND RESULTS: The children with CP had significantly poorer mathematical and visual-spatial abilities than the TD group. For the TD group age was the best predictor of mathematical ability, in the CP group receptive vocabulary and visual perception abilities were the best predictors of mathematical ability. CONCLUSION AND IMPLICATIONS: The CP group had extensive difficulties with visual perception; visual short-term memory; visual reasoning; and mental rotation all of which were associated with their mathematical abilities. These findings have implications for the teaching of visual perception and visual memory skills in young children with CP as these may help the development of mathematical abilities.
