Sensory systems are essential for perceiving and conceptualizing our semantic knowledge about the world and the way we interact with it. Despite studies reporting neural changes to compensate for the absence of a given sensory modality, studies focusing on the assessment of semantic processing reveal poor performances by deaf individuals when compared with hearing individuals. However, the majority of those studies were not performed in the linguistic modality considered the most adequate to their sensory capabilities (i.e., sign language). Therefore, this exploratory study was developed focusing on linguistic modality effects during semantic retrieval in deaf individuals in comparison with their hearing peers through a category fluency task. Results show a difference in performance between the two linguistic modalities by deaf individuals as well as in the type of linguistic clusters most chosen by participants, suggesting a complex clustering tendency by deaf individuals.

Sign Language Recognition System for Deaf Patients: Protocol for a Systematic Review.
JMIR Res Protoc
January 2025
Department of Computer Science, Universidade Federal de Minas Gerais, Belo Horizonte, Brazil.
Background: Individuals with hearing impairments may face hindrances in health care assistance, which may significantly impact the prognosis and the incidence of complications and iatrogenic events. Therefore, the development of automatic communication systems to assist the interaction between this population and health care workers is paramount.
Objective: This study aims to systematically review the evidence on communication systems using human-computer interaction techniques developed for deaf people who communicate through sign language that are already in use or proposed for use in health care contexts and have been tested with human users or videos of human users.
Production of real signs but not pseudosigns affected by age of acquisition in American Sign Language.

Research shows that insufficient language access in early childhood significantly affects language processing. While the majority of this work focuses on syntax, phonology also appears to be affected, though it is unclear exactly how. Here we investigated phonological production across age of acquisition of American Sign Language (ASL).

BMJ Open
January 2025
The Lundquist Institute for Biomedical Innovation, Torrance, California, USA.
Objective: Investigate whether deaf or hard of hearing (D/HH) patients with COVID-19 exhibited different hospitalisation outcomes compared with hearing patients with COVID-19.
Design: Cohort study SETTING: Statewide Inpatient Databases for Florida, Maryland, New York and Washington, for the year 2020.
Participants: Records of patients aged 18-64 years with COVID-19 PRIMARY OUTCOMES AND MEASURES: Differences in in-hospital death, 90-day readmission, length of stay, hospitalisation cost, hospitalisation cost per day, intensive care unit (ICU) or coronary care unit (CCU) utilisation and ventilation use were evaluated.
South African parents' views on oral, signing, and bilingual communication for Deaf or hard-of-hearing children.

Department of Audiology, Faculty of Human and Community Development, University of the Witwatersrand, Braamfontein, South Africa.
Background: Parents of Deaf or hard-of-hearing (DHH) children are faced with a plethora of overwhelming decisions concerning their children, particularly during the early stages of development. Among these decisions are those concerning assistive devices and the modes of communication for their child.
Objectives: The aim of this study was to explore the perceptions of parents of DHH children towards the various modes of communication for their children within the South African context.
Individual Differences in the Recognition of Spectrally Degraded Speech: Associations With Neurocognitive Functions in Adult Cochlear Implant Users and With Noise-Vocoded Simulations.

Department of Otolaryngology - Head & Neck Surgery, Vanderbilt University Medical Center, Nashville, TN, USA.
When listening to speech under adverse conditions, listeners compensate using neurocognitive resources. A clinically relevant form of adverse listening is listening through a cochlear implant (CI), which provides a spectrally degraded signal. CI listening is often simulated through noise-vocoding.
