Starved For Knowledge: The Effect Of Language Deprivation And “Mainstream” Education On Deaf Accessibility To The United States Education System, Katherine Arpino
Starved For Knowledge: The Effect Of Language Deprivation And “Mainstream” Education On Deaf Accessibility To The United States Education System, Katherine Arpino
Honors Scholar Theses
The prevalence of language deprivation in deaf and hard of hearing youth makes the United States public education system fundamentally inaccessible to that portion of the population. Previous research has demonstrated that depriving prelingually deaf children of an accessible, visual language during the critical language acquisition period has long-term effects on their reading comprehension, mental health, social development, and cognitive development (Friedman and Rusoe, 2015; Hall et al., 2019; Cheng et al., 2019; Hall, 2017). Furthermore, the lack of bilingual-bimodal education (or purely signed education) in the United States public education system sets deaf children up for failure, as they …

Previous studies with deaf adults reported reduced N170 waveform asymmetry to visual words, a finding attributed to reduced phonological mapping in left-hemisphere temporal regions compared to hearing adults. An open question remains whether this pattern indeed results from reduced phonological processing or from general neurobiological adaptations in visual processing of deaf individuals. Deaf ASL signers and hearing nonsigners performed a same-different discrimination task with visually presented words, faces, or cars, while scalp EEG time-locked to the onset of the first item in each pair was recorded. For word recognition, the typical left-lateralized N170 in hearing participants and reduced left-sided asymmetry …
