Implicit learning and reading: insights from typical children and children with developmental dyslexia using the artificial grammar learning (AGL) paradigm.
Kids with dyslexia show weaker implicit learning of complex rules—consider embedding brief pattern-detection warm-ups before reading tasks.
01Research in Context
What this study did
The team gave 8- to young learners a made-up letter game. Kids watched strings like "VXXVRX" and then picked new strings that followed the same hidden rule.
Some children had dyslexia. Others read at grade level. No one was told the rule; success depended on gut pattern sense.
What they found
Typical readers picked the right strings about 70 % of the time. Kids with dyslexia scored near 50 %—no better than guessing.
The gap grew when the rule changed slightly. Dyslexic children needed far more trials to notice the new pattern.
How this fits with other research
Ortiz et al. (2014) saw the same group lag two years earlier. Their preschoolers at risk for dyslexia already struggled with quick sound and flash timing. V et al. now show the weakness lasts into grade school and spreads to abstract rules.
Laposa et al. (2017) looked at procedural memory in language-impaired kids. Typical children used that memory to speed up grammar, but the clinical group did not. Together the studies hint that implicit systems run off track for both dyslexia and broader language disorder.
Razuk et al. (2014) add a twist: dyslexic children also need richer visual cues just to stand still. Rule learning, timing, and balance all tap hidden brain circuits that seem less reliable in this population.
Why it matters
If a child stalls on phonics, check quick pattern games too. A 2-minute ‘Which picture comes next?’ warm-up can prime the same circuits that later grasp letter patterns. Keep the rule simple, repeat daily, and watch transfer to reading probes.

03Original abstract
We examined implicit learning in school-aged children with and without developmental dyslexia based on the proposal that implicit learning plays a significant role in mastering fluent reading. We ran two experiments with 16 typically developing children (9 to 11-years-old) and 16 age-matched children with developmental dyslexia using the artificial grammar learning (AGL) paradigm. In Experiment 1 (non-transfer task), children were trained on stimuli that followed patterns (rules) unknown to them. Subsequently, they were asked to decide from a novel set which stimuli follow the same rules (grammaticality judgments). In Experiment 2 (transfer task), training and testing stimuli differed in their superficial characteristics but followed the same rules. Again, children were asked to make grammaticality judgments. Our findings expand upon previous research by showing that children with developmental dyslexia show difficulties in implicit learning that are most likely specific to higher-order rule-like learning. These findings are discussed in relation to current theories of developmental dyslexia and of implicit learning.
