Naming fluency and reading development

In two ESRC funded projects we sought to shed light on the link between children’s performance on “Rapid Automatized Naming” (RAN) tasks and reading. RAN tasks involve children naming sets of very familiar things (objects, colours, letters or numbers) as quickly as they can. Poor performance on RAN tasks has been linked to reading difficulties, though the underlying cause of the RAN-reading link is not fully understood. We therefore carried out a large study contrasting Year 3 and 4 children poor at RAN tasks with a closely matched control group. As predicted, the low RAN group had a modest difficulty with both reading and spelling, which persisted into secondary school. We also identified a difficulty discriminating simple visual stimuli, like oblique lines and curves, as one potential source of their RAN difficulty. We also showed that RAN difficulties seem to particularly impair children’s stored knowledge of the written form of words. In English this knowledge is crucial for reading and spelling words with irregular spellings (like “pint”, or “yacht”).
