Age of reading acquisition does not affect visual hemifield asymmetries for naming imageable nouns.
Nouns of high imageability and low or high age of reading acquisition were presented bilaterally to adult subjects, who were asked to name them. Order of report of nouns appearing in the LVF and in the RVF was counterbalanced. RVF nouns were more accurately named, regardless of age of reading acquisition. This result is inconsistent with the hypothesis that the right cerebral hemisphere acquires its 'visual vocabulary' during the early stages of learning to read. Despite being matched to high reading age nouns on frequency and imageability, low reading age nouns were more accurately named.
