Description

Visual processing is what the brain does with the input that comes through vision: recognising, ordering and interpreting visual information. It lets learners recognise letters, numbers and symbols, read quickly and accurately, copy and solve problems correctly, and work with diagrams, drawings and geometric shapes; visual-motor integration, the coordination of hand and eye, is part of it and supports handwriting. Learners with dyslexia or dyscalculia may process words and numbers visually in different ways, which the LVN traces in many cases to phonological difficulties that disrupt visual attention during reading. It is measured with visual discrimination and matching tasks, figure-copying and design-copying tests, block design and mental rotation tasks, and computer-based tasks that use non-linguistic symbols so language skills do not affect scores. It overlaps closely with spatial ability, and is distinct from eyesight itself, which access covers.

Implications

Context

  • Cluttered pages, dense layouts and small print add visual load; clear layout and spacing reduce it.
  • Copying from a board or between representations places demands on visual processing and visual-motor integration.
  • Learners with hearing loss may rely more on visual channels, which favours well-designed visual material.

Target Learners

  • Young children learning letters, numbers and handwriting.
  • Learners with dyslexia or dyscalculia, and older adults with declining vision.

Target Learning Objectives

  • Word recognition and reading fluency.
  • Calculation, geometry and working with diagrams.
  • Handwriting and drawing.

Claims

Measures

  • NAB Visual Discrimination Task (Stern & White, 2003): a match-to-sample task measuring adults' visual perception and visual-spatial skill.
  • Woodcock-Johnson Tests of Cognitive Abilities (Schrank et al., 2014): includes visual processing tests such as block rotation and spatial relations.
  • Rey-Osterrieth Complex Figure Test (ROCF) (Rey, 1941): copying and recalling a complex figure, for visual-spatial processing and memory.
  • Computer-Based Vision Tasks (Boros et al., 2016): responding to the position or a visual feature of letters, digits or non-linguistic symbols.
  • Beery-Buktenica Developmental Test of Visual-Motor Integration, 6th edition (Beery et al., 2010): copying increasingly complex geometric designs, with supplementary visual perception and motor coordination tests, for ages 2 to 100.
  • Frostig Developmental Test of Visual Perception (DTVP) (Frostig, 1963): visual processing and visual-motor integration for ages 4 to 8.
  • Block Design subtest (WISC-IV) (Wechsler, 2003): mentally assembling and analysing abstract visual designs, for ages 6 to 16.
  • Children's Mental Transformation Task (CMTT) (Levine et al., 1999): spatial skills in children aged 4 to 7.
  • Access: hearing loss can strengthen reliance on vision, and declining eyesight can weaken visual processing.
  • Attention: visual selective attention depends on visual processing, and in dyslexia attention can disrupt it.
  • Working Memory: visual processing feeds information into visual working memory.
  • Safety: children in unsafe neighbourhoods may become quicker to notice threatening visual cues.
  • Sleep: sleep helps consolidate visual learning, and short sleep goes with weaker visual processing.
  • Number Sense: visual processing supports estimating quantities and is related to mathematics achievement.
  • Operations and Place Value: visual processing and visual-motor integration support accurate calculation.
  • Writing Skills: visual-motor integration underpins handwriting.
  • Sensory Integration: sensory integration difficulties can raise or lower thresholds for visual input.
  • Stereotype Threat: reported gender gaps on spatial tasks may reflect stereotypes rather than ability.
  • Critical Thinking: visuospatial skill supports representing ideas and reasoning about relations.
  • Academic and Critical Literacy: visual processing underlies handwriting, drawing and mathematical thinking.
