when your brain works differently

Learning styles are a myth. Neurodivergence is not, and conflating the two does real harm in both directions. The difference is that one is a preference people report and the other is a difference in how attention, working memory and language processing operate, with accommodations that have evidence behind them.

The distinction that matters: preference versus access.
"I am a visual learner" is a preference, and preferences do not predict outcomes. "I cannot hold six unrelated instructions in working memory" is an access need, and designing around it changes what a person can do. Treating access needs as preferences is how people get told to try harder at something the format made impossible. working memory
ADHD: put working memory outside the head.
The bottleneck is usually not understanding but holding and sequencing. Write the steps down where they stay visible. Break work into units short enough to finish before attention moves. Use interest and urgency deliberately rather than treating them as character flaws, because for this wiring they are the mechanism that engages, not a substitute for one. Body doubling — working alongside someone — is widely reported to help and costs nothing to try. ADHD
Autism: remove ambiguity, then get out of the way.
Much of what looks like difficulty is the overhead of decoding unstated expectations, on top of sensory input the room is imposing. State the goal explicitly, say what done looks like, keep the structure predictable, and let the person control the sensory environment. Monotropism describes the tendency toward deep single-channel attention, and the productive move is to build around that depth rather than interrupt it into a shape that suits everyone else. monotropism
Dyslexia: teach the code explicitly, and stop grading the wrong thing.
Structured literacy — explicit, systematic, cumulative phonics of the Orton-Gillingham lineage — has the strongest evidence base of any intervention here, and it is not what most classrooms do. Separately: text-to-speech and speech-to-text remove a decoding tax that has nothing to do with whether the person understands the material. Marking down reasoning because of spelling measures the wrong variable. structured literacy
Reduce the load the format adds.
Cognitive load theory separates the difficulty inherent in the material from the difficulty your presentation added. Dense slides read aloud, instructions given only verbally, information split across two places the eye must jump between — all of it consumes capacity that was meant for the subject. This costs everyone something and costs some people everything. cognitive load
Design for the edges and the middle comes free.
Captions were built for deaf viewers and are now used by most people in noisy rooms. Curb cuts were built for wheelchairs and carry every suitcase and pushchair in the city. Universal Design for Learning generalises the pattern: multiple means of representation, engagement and expression, decided at design time rather than granted later as an exception someone has to ask for.
