Resumo(s)
This study presents a meta-analytic review of serial rapid automatized naming
(RAN) deficits in individuals with dyslexia relative to typical readers (based on
216 effect sizes comprising 8335 dyslexic readers, 14,083 age-matched controls, and 921 reading-matched controls). A random-effects model analysis
indicated a large impairment in speeded RAN in individuals with dyslexia
compared with age-matched controls (d = 1.19) but a similar performance
when compared with reading-matched controls (d = 0.13). In addition, dyslexic
readers presented a deficit in discrete-naming formats (d = 0.74), although the
deficit in serial RAN was notably larger; hence, adding seriality is particularly
detrimental for these readers. The deficit appears to span all stimulus types
(alphanumeric and nonalphanumeric), indicating that processes beyond letter
processing are responsible for the delays and are independent of set size. Poor
RAN is a long-term and universal symptom of dyslexia, and the transparency of
the writing system does not influence its severit
