“…An indication that this may nevertheless be a real group difference, yet not linked to task performance, comes from an analysis of data from participants who performed both above and below chance level on the task, which showed a significant interaction. Such a difference is consistent with data from a visual hemifield study by D'Hondt and Leybaert (2003). In that study, deaf and hearing participants were required to make rhyme judgments in response to sequentially presented words.…”

We used electrophysiology to determine the time-course and distribution of neural activation during an English word rhyme task in hearing and congenitally deaf adults. Behavioral performance by hearing participants was at ceiling and their ERP data replicated two robust effects repeatedly observed in the literature. First, a sustained negativity, termed the contingent negative variation (CNV), was elicited following the first stimulus word. This negativity was asymmetric, being more negative over the left than right sites. The second effect we replicated in hearing participants was an enhanced negativity (N450) to non-rhyming second stimulus words. This was largest over medial, parietal regions of the right hemisphere. Accuracy on the rhyme task by the deaf group as a whole was above chance level, yet significantly poorer than hearing participants. We examined only ERP data from deaf participants who performed the task above chance level (n=9). We observed indications of subtle differences in ERP responses between deaf and hearing groups. However, overall the patterns in the deaf group were very similar to that in the hearing group. Deaf participants, just as hearing participants, showed greater negativity to non-rhyming than rhyming words. Furthermore the onset latency of this effect was the same as that observed in hearing participants. Overall, the neural processes supporting explicit phonological judgments are very similar in deaf and hearing people, despite differences in the modality of spoken language experience. This supports the suggestion that phonological processing is to a large degree amodal or supramodal.

“…In contrast, no interactions involving hemisphere approached significance in the deaf group. This pattern is consistent with the results of D’Hondt and Leybaert (2003) who found a left hemisphere (RVF) advantage for hearing participants making rhyme judgments (“yes” responses) but no hemispheric asymmetry for deaf participants who were matched on rhyme ability and reading level. Thus, the existing ERP literature with adult deaf readers suggests a more bilateral neural response to visual words compared to hearing readers, but the factors that lead to reduced left lateralization in this population remain unclear.…”

The N170 ERP component differs in laterality, distribution, and association with continuous reading measures for deaf and hearing readers

et al. 2017

The temporo-occipitally distributed N170 ERP component is hypothesized to reflect print-tuning in skilled readers. This study investigated whether skilled deaf and hearing readers (matched on reading ability, but not phonological awareness) exhibit similar N170 patterns, given their distinct experiences learning to read. Thirty-two deaf and 32 hearing adults viewed words and symbol strings in a familiarity judgment task. In the N170 epoch (120–240 ms) hearing readers produced greater negativity for words than symbols at left hemisphere (LH) temporo-parietal and occipital sites, while deaf readers only showed this asymmetry at occipital sites. Linear mixed effects regression was used to examine the influence of continuous measures of reading, spelling and phonological skills on the N170 (120–240ms). For deaf readers, better reading ability was associated with a larger N170 over the right hemisphere (RH), but for hearing readers better reading ability was associated with a smaller RH N170. Better spelling ability was related to larger occipital N170s in deaf readers, but this relationship was weak in hearing readers. Better phonological awareness was associated with smaller N170s in the LH for hearing readers, but this association was weaker and in the RH for deaf readers. The results support the phonological mapping hypothesis for a left-lateralized temporo-parietal N170 in hearing readers and indicate that skilled reading is characterized by distinct patterns of neural tuning to print in deaf and hearing adults.

“…Left hemisphere lateralization has been described in deaf adults for sign language processing (e.g., Grossi et al, 1996) and in deaf children exposed to cued speech, which is a visual mode of communication using handshapes in combination with the mouth movements of speech, to represent the phonemes of a spoken language. Deaf participants and hearing controls were also shown to display comparable left hemisphere specialization for semantic processing of written language (D'Hondt and Leybaert, 2003), and similar accuracy of phonological representations (Leybaert, 2000), suggesting that semantic and phonological abilities develop independently of the modality (acoustic versus visual) through which language is perceived. Moreover, the production of signs activates regions similar to those implicated in spoken language use, including Broca's area (e. g., Corina et al, 2003;Emmorey et al, 2007).…”

The objective of this review is to obtain a better understanding of the relationship between manual asymmetries and hemispheric specialization by focusing on the development of hand preference and cerebral lateralization of language. We first sought to describe the development of manual asymmetries for different activities (i.e., grasping and manipulating objects vs. communicating through gestures), and the development of cerebral asymmetries, before examining available data on the association between hand preference and HS for language. We also analyzed behavioral studies on the relation between hand preference and language development, as well as more specific studies on the relation between the cerebral control of gestures and language. Finally, we aimed at providing a wider view on functional asymmetries by emphasizing the need to study hemispheric specialization for functions other than language, and in particular for visual attention.
