Reading, laterality, and the brain: early contributions on reading disabilities by Sara S. Sparrow.

Whitehouse et al. (2014) traced the roots of today’s developmental-disability tests. They told the story of Sara Sparrow’s early work on dyslexia and brain laterality.

The paper is a narrative review, not a new experiment. It shows how Sparrow’s ideas from decades ago still shape the checklists and neuropsych tools you use now.

Sparrow linked reading trouble to how the two sides of the brain work. Her tests for phonology, memory, and lateral bias became seeds for modern assessment batteries.

The review argues that her early focus on brain-based profiles is still useful for spotting kids with autism, ID, or dyslexia today.

Foti et al. (2015) meta-analysis backs Sparrow’s hunch. It found large, broad cognitive gaps in kids with reading disabilities, proving that you must test more than just letter sounds.

Scalzo et al. (2015) extends the idea to children with intellectual disability. They showed that early phonological awareness predicts later reading gains, echoing Sparrow’s push to probe these skills.

Danforth (2011) offers a warning. It shows another pioneer, Kirk, kept changing the definition of learning disability for political reasons. Together the papers say: borrow Sparrow’s tools, but stay critical of the labels.

When you assess a child who struggles to read, sample phonology, memory, and laterality like Sparrow did. Use quick laterality tasks or non-word lists to find the weak channel. Then write goals that shore up that channel instead of drilling sight words alone.
