Dyslexia Reframed
Does struggling to read necessarily mean something is wrong with how the brain works?
Reading is a recent invention, and it co-opts much older brain systems evolved for other purposes entirely. So a difficulty with it may be telling us less about a fault than about how those systems are organised differently from one person to the next.
In people with dyslexia, differences in how the brain develops and functions can make reading difficult. Those differences are usually understood as deficits. But could they instead reflect a brain configured differently? That is the possibility this research set out to investigate.
Dr Taylor’s research proposes that people with dyslexia are specialised towards learning through more global exploration. This involves, for example, taking in the whole rather than the parts, understanding how the pieces of a complex problem relate and anticipating how a situation will unfold. This specialisation comes with trade-offs in processes that reading and spelling draw on heavily, such as handling the precise sequences of letters and sounds, and making those processes automatic.
The difficulties and capabilities can be understood as two sides of the same specialisation. Dyslexia appears to be a deficit because the trade-off is what we have noticed first, particularly since it affects a skill often bound up with how we judge intelligence.
Look at the whole picture and the very specialisation that makes reading hard is what lets someone come at a problem from an unexpected angle, or see deeper patterns others miss.
A specialisation in exploration
This specialisation is part of the wider theory of Complementary Cognition. This proposes that humans evolved complementary ways of processing information, along a continuum from global exploration through local exploration to what has been termed exploitation: applying what is already known. Through language and collaboration, these complementary specialisations combine to generate knowledge and solutions beyond the reach of any individual.
This makes us interdependent: our capacity to learn and adapt relies on people with complementary specialisations working together. Seen this way, dyslexia is one expression of the exploratory specialisation that contributes to our species’ ability to adapt. Many people now being diagnosed with ADHD likely also sit towards the more exploratory end of the continuum – a possibility discussed in Dr Taylor’s published research.
Part of something bigger
If people with dyslexia have a specialisation rather than a deficit, the questions we ask about education and work change.
Most schooling rewards accurately reproducing what is already known. That plays to the refining-and-applying end of the continuum and leaves the exploratory end with little room to show what it can do. People specialised towards exploration are then judged almost entirely on the processes they find hardest, and rarely on the kinds of insights their brains are suited to provide.
This does not mean dropping support for reading, writing and the difficulties that come with them. That support is important. But it is only half of what is needed. Exploratory thinking also needs room to develop and be recognised: chances to investigate, to make connections, to approach a problem in an unfamiliar way.
The stakes are collective, not just individual. If our human capacity to adapt depends on combining complementary specialisations, then making room for more exploratory strategies is not a kindness we extend to some people, but a condition for the kind of problem-solving we all rely on.
