Neural effects differ for learning highly iconic versus non-iconic signs in hearing adults.

Little is known about the neural changes that accompany sign language learning by hearing adults. We used ERPs and a word-sign matching task to assess how learning impacted the N400 priming effect (reduced negativity for translations compared to unrelated trials). English monolinguals (N = 32) learned 100 ASL signs - half highly iconic (meaning was guessable), half non-iconic.

Orthographic and Phonological Code Activation in Deaf and Hearing Readers.

Grainger et al. (2006) were the first to use ERP masked priming to explore the differing contributions of phonological and orthographic representations to visual word processing. Here we adapted their paradigm to examine word processing in deaf readers.
