Location negative priming effects in children with developmental dyslexia: An event-related potential study.

Ma et al. (2016) watched brain waves while kids ignored distractions. They compared children with dyslexia to same-age peers without reading problems. Everyone played a computer game that required ignoring pictures that had just been in the wrong spot.

The team measured two brain markers: an early wave that shows first filtering and a late wave that shows final checking. Smaller dips in these waves mean weaker inhibition.

Kids with dyslexia showed smaller "negative priming" dips at both time points. This means their brains were slower to tag a distraction as off-limits. The gap showed up in early sensory stages and again in late decision stages.

In plain words, the dyslexic group could not slam the door on irrelevant sights as firmly as the control group.

Schertz et al. (2016) extends these results to adults. They found the same inhibition weakness using questionnaires and lab tasks instead of brain waves. Together the two papers trace one steady trait from childhood to adulthood.

Van Hanegem et al. (2014) seems to contradict the picture. They showed that executive-function scores did not predict later reading or spelling gains after phonics training. The key difference is outcome: Yujun measured real-time distraction blocking, while E et al. measured long-term literacy progress. Weak inhibition exists, but training it does not speed up reading fluency.

Adams et al. (2024) adds another null nail: working-memory drills also failed to boost decoding. The pattern is clear—cognitive exercises alone do not repair reading; direct literacy instruction remains essential.

You now have brain evidence that dyslexic learners are extra vulnerable to visual clutter. Keep therapy rooms tidy, use plain backgrounds on slides, and limit sidebar animations. These small environmental cuts can free brain power for the actual reading task. Pair this support with solid phonics; don't burn session time on generic inhibition games that won't move reading scores.
