The Organization of Working Memory Networks is Shaped by Early Sensory Experience.

Early deafness results in crossmodal reorganization of the superior temporal cortex (STC). Here, we investigated the effect of deafness on cognitive processing. Specifically, we studied the reorganization, due to deafness and sign language (SL) knowledge, of linguistic and nonlinguistic visual working memory (WM). We conducted an fMRI experiment in groups that differed in their hearing status and SL knowledge: deaf native signers, and hearing native signers, hearing nonsigners. Participants performed a 2-back WM task and a control task. Stimuli were signs from British Sign Language (BSL) or moving nonsense objects in the form of point-light displays. We found characteristic WM activations in fronto-parietal regions in all groups. However, deaf participants also recruited bilateral posterior STC during the WM task, independently of the linguistic content of the stimuli, and showed less activation in fronto-parietal regions. Resting-state connectivity analysis showed increased connectivity between frontal regions and STC in deaf compared to hearing individuals. WM for signs did not elicit differential activations, suggesting that SL WM does not rely on modality-specific linguistic processing. These findings suggest that WM networks are reorganized due to early deafness, and that the organization of cognitive networks is shaped by the nature of the sensory inputs available during development.

Toward an Understanding of the Experiences of Deaf Gay Men: An Interpretative Phenomenological Analysis to an Intersectional View.

Similarities between developing a deaf identity and a sexual minority identity have been postulated upon the parallel experience of oppressed minority positions. Sign language interviews with eight deaf gay British men explored their intersectional understanding of deaf-gay lived experiences, analyzed through Interpretative Phenomenological Analysis. During their adolescence deaf gay men sometimes experienced being in a position where they were trying hard to be something they were not: oral and heterosexual for hearing non-signing others (including heterosexual members of their family of origin). Participants spoke of increasingly being drawn toward a welcoming signing cultural world that supported them against deaf minority stress. Coming out as gay presented not only potential family of origin difficulties, but also threatened connection with the deaf community, leaving participants intensely fearful of gay visibility and stigma. Self-fulfillment and community building was sought through positions that ranged from oralist-heteronormativity through to the deaf-gay community. Along the way these journeys included experiences of pride and success alongside those of struggle. Our findings extend research on intersectionality by presenting a distinct set of obstacles, caveats, and nuances to identity conjunction.
