While a substantial body of work has suggested that deafness brings about an increased allocation of visual attention to the periphery there has been much less work on how using a signed language may also influence this attentional allocation. Signed languages are visual-gestural and produced using the body and perceived via the human visual system. Signers fixate upon the face of interlocutors and do not directly look at the hands moving in the inferior visual field. It is therefore reasonable to predict that signed languages require a redistribution of covert visual attention to the inferior visual field. Here we report a prospective and statistically powered assessment of the spatial distribution of attention to inferior and superior visual fields in signers – both deaf and hearing – in a visual search task. Using a Bayesian Hierarchical Drift Diffusion Model, we estimated decision making parameters for the superior and inferior visual field in deaf signers, hearing signers and hearing non-signers. Results indicated a greater attentional redistribution toward the inferior visual field in adult signers (both deaf and hearing) than in hearing sign-naïve adults. The effect was smaller for hearing signers than for deaf signers, suggestive of either a role for extent of exposure or greater plasticity of the visual system in the deaf. The data provide support for a process by which the demands of linguistic processing can influence the human attentional system.

Abstract Deaf people’s lives are predicated to some extent on working with sign language interpreters. The self is translated on a regular basis and is a long-term state of being. Identity becomes known and performed through the translated self in many interactions, especially at work. (Hearing) others’ experience of deaf people, largely formed indirectly through the use of sign language interpreters, is rarely understood as intercultural or from a sociocultural linguistic perspective. This study positions itself at the cross-roads of translation studies, sociolinguistics and deaf studies, to specifically discuss findings from a scoping study that sought, for the first time, to explore whether the experience of being ‘known’ through translation is a pertinent issue for deaf signers. Through interviews with three deaf signers, we examine how they draw upon their linguistic repertoires and adopt bimodal translanguaging strategies in their work to assert or maintain their professional identity, including bypassing their representation through interpreters. This group we refer to as ‘Deaf Contextual Speakers’ (DCS). The DCS revealed the tensions they experienced as deaf signers in reinforcing, contravening or perpetuating language ideologies, with respect to assumptions that hearing people make about them as deaf people, their language use in differing contexts; the status of sign language; as well as the perceptions of other deaf signers about their translanguaging choices. This preliminary discussion of DCS’ engagement with translation, translanguaging and professional identity(ies) will contribute to theoretical discussions of translanguaging through the examination of how this group of deaf people draw upon their multilingual and multimodal repertoires, contingent and situational influences on these choices, and extend our understanding of the relationship between language use, power, identity, translation and representation.

Prior studies investigating cortical processing in Deaf signers suggest that life-long experience with sign language and/or auditory deprivation may alter the brain’s anatomical structure and the function of brain regions typically recruited for auditory processing (Emmorey et al., 2010; Pénicaud, et al., 2012 inter alia). We report the first investigation of the task-negative network in Deaf signers and its functional connectivity – the temporal correlations among spatially remote neurophysiological events. We show that Deaf signers manifest increased functional connectivity between posterior cingulate/precuneus and left medial temporal gyrus (MTG), but also inferior parietal lobe and medial temporal gyrus in the right hemisphere- areas that have been found to show functional recruitment specifically during sign language processing. These findings suggest that the organization of the brain at the level of inter-network connectivity is likely affected by experience with processing visual language, although sensory deprivation could be another source of the difference. We hypothesize that connectivity alterations in the task negative network reflect predictive/automatized processing of the visual signal.

AbstractThis study used ERPs to a) assess the neural correlates of cross-linguistic, cross-modal translation priming in hearing beginning learners of American Sign Language (ASL) and deaf highly proficient signers and b) examine whether sign iconicity modulates these priming effects. Hearing learners exhibited translation priming for ASL signs preceded by English words (greater negativity for unrelated than translation primes) later in the ERP waveform than deaf signers and exhibited earlier and greater priming for iconic than non-iconic signs. Iconicity did not modulate translation priming effects either behaviorally or in the ERPs for deaf signers (except in a 800–1000 ms time window). Because deaf signers showed early translation priming effects (beginning at 400ms-600ms), we suggest that iconicity did not facilitate lexical access, but deaf signers may have recognized sign iconicity later in processing. Overall, the results indicate that iconicity speeds lexical access for L2 sign language learners, but not for proficient signers.

In this study the sign-based perceptual abilities of 59 deaf children are investigated. Like many hearing speaking children, deaf signing children appear to perceive isolated lexical items based on the formational parameters of those items. Also, deaf signers show trends similar to those exhibited by hearing speakers for the development of the perceptual ability necessary to distinguish between minimal pairs within their respective language systems.
