A language-based learning difference affecting up to 20% of the population. Not a failure of intelligence — a different architecture of the reading brain.
Dyslexia is a language-based learning disability characterised by difficulties with accurate and fluent word recognition, poor spelling, and impaired decoding. The core deficit lies in phonological processing — the ability to map written letters to their corresponding sounds.
It is not caused by low intelligence, poor motivation, or insufficient teaching. Brain imaging consistently reveals differences in the activation patterns of left-hemisphere language regions. These are variations in brain wiring, not signs of damage.
Classified as a Specific Learning Disorder under DSM-5 and ICD-11, dyslexia is the most common learning disability — estimates suggest 15–20% of the population displays some degree of its symptoms.

The most consistently documented deficit in dyslexia is phonological processing — perceiving, identifying, and manipulating individual sounds (phonemes) within words. Select a mode to observe how this deficit disrupts reading.
fMRI research (Shaywitz et al., Yale) shows consistent differences in language-area activation patterns. Toggle between reader profiles to compare. Hover a brain region for detail.

No simulation can replicate the full cognitive load of reading with dyslexia. This approximates some of the perceptual noise that may accompany the process. Toggle effects and adjust intensity.
Clinical observation and research suggest many individuals with dyslexia demonstrate pronounced abilities in areas relying on right-hemisphere and holistic processing. Explore the constellation — hover a star to reveal a strength.
Elevated 3D thinking and mental rotation; linked to differential right-hemisphere spatial processing.
Strong capacity for big-picture, systems-level thinking and detecting patterns across domains.
Non-linear reasoning frequently manifests as original, unconventional approaches to challenges.
Many individuals develop highly fluent spoken language and narrative skills as compensatory strengths.
Disproportionately high representation among entrepreneurs and creative professionals is documented.
Some research indicates wider peripheral visual attention — useful in art, design, and navigation.
