Summary
Learning to read is a great challenge for deaf children due to their limited access to the sounds andlimited knowledge of the
language they learn to read. Deaf adults’illiteracy levels aremuch higher than that of their hearing peers, but some deaf
individuals can and do become skilled readers, though in a qualitatively different way than typically observed in hearing
readers. New evidence shows that relative to skilled hearing readers (SKH), deaf readers do not activate phonological
codes, but activate orthographic codes and show greater use of semantic informationduring word reading. Eye movement
data shows that skilled deaf readers (SKD) skip words more often, and refixate words less often than SKHreaders do. In
other words, SKDreaders are more efficient at processing words accurately within a single fixation than SKHreaders are, and
this may be in part explained by 1) faster processing of visual information, 2) more direct connections between orthography
and semantics, or 3) a combination of these two factors. This has been termed the word processing efficiency (WPE)
hypothesis and the hypothesis predicts that SKD readers will show earlier activation of orthographic codes, no phonological
activation, and thus faster access to semantic codes compared to SKH readers. I will test this hypothesis by investigating
and comparing the time-course of word processing in SKDand SKHreaders, by 1) observing participants’ eye movements
during reading to determine the earliest point of activation of parafoveal visual, orthographic, phonological, and semantic
codes, and 2)assessing the neural underpinnings of the WPE hypothesis with respect to the timing and types of codes with
ERP measures. The results will lead to empirically tested solutions for the reading development of deaf children that are not
based on how reading develops in children who can hear and will lead to more effective reading instruction for deaf children
to increase their functional literacy.
