An empirical estimate of how many deaf and hard-of-hearing persons use sign language in the USA was obtained a half-century ago, but no study has measured how many people sign regardless of deafness. This study estimated the number of deaf, hard-of-hearing, and hearing adult signers. Concatenation of the 2010-2018 National Health Interview Surveys…

Objective: Two-thirds of U.S. colleges are near vape shops, where higher rates of underage sales exist. This study examined vape shop compliance with state-mandated age-of-sale signs, the presence of age-of-entry signs and the tobacco industry's "We Card" sign. Participants: Random sample of 614 California vape shops, stratified by…

Recent research has shown that a distinct variety of American Sign Language, known as Black ASL, developed in the segregated schools for deaf African Americans in the US South during the pre-civil rights era. Research has also shown that in some respects Black ASL is closer than most white varieties to the standard taught in ASL classes and found…

The ability to associate different types of number representations referring to the same quantity (symbolic Arabic numerals, signed/spoken number words, and nonsymbolic quantities), is an important predictor of overall mathematical success. This foundational skill--mapping--has not been examined in deaf and hard-of-hearing (DHH) children. To…

Name sign systems have been described in many deaf communities around the world. The most frequent name sign types are associated with an individual's appearance, for example, a signers' hairstyle, clothes, and physical features such as height, weight, etc. However, a recent study that examined name signs in Swedish Sign Language, for example,…

Multiple studies have reported mathematics underachievement for students who are deaf, but the onset, scope, and causes of this phenomenon remain understudied. Early language deprivation might be one factor influencing the acquisition of numbers. In this study, we investigated a basic and fundamental mathematical skill, automatic magnitude…

This dissertation presents the judgment of what is 'correct' American Sign Language (ASL) structure by the younger generation, using the word order strategies that were used in older generation signers, as well as younger generation attitudes towards the ideology of ASL being a SOV language. This study used an on-line survey to evaluate 83…

The role of fingerspelling as to its unique features, its use, and its function in the culture and education of the Saudi Deaf population has not been examined. Specifically, this study focuses on assessing historical and existing attitudes and beliefs of Saudi Deaf people regarding the importance of fingerspelling and situations in which they use…

Naturalistic studies show that children can create language-like communication systems in the absence of conventional language. However, experimental evidence is mixed. We address this discrepancy using an experimental paradigm that simulates naturalistic sign creation. Specifically, we tested if a sample of 6- to 12-year-old children (52 girls…

Using a free-recall paradigm, we explored the effects of age of acquisition and category size on verbal fluency in Turkish Sign Language (Türk Isaret Dili [TID]). We studied the semantic and phonological fluency task performances of deaf native and deaf late adult signers. We measured the number of correct responses and performed a time course…

Among the existing sign language assessment tools, only a small number can be used in clinical settings. This contribution aims at presenting three comprehension assessment tests (two lexical and one syntactic) that offer a solid basis to build tools to assess language impairments in deaf signing adults. We provide the material and guidelines,…

The aim of this study is twofold: To examine if deafness is invariably associated with deficits in executive function (EF) and to investigate the relationship between sign language proficiency and EF in deaf children of deaf parents with early exposure to a sign language. It is also the first study of EF in children acquiring Polish Sign Language.…

Recent evidence suggests that deaf children with CIs exposed to nonnative sign language from hearing parents can attain age-appropriate vocabularies in both sign and spoken language. It remains to be explored whether deaf children with CIs who are exposed to early nonnative sign language, but only up to implantation, also benefit from this input…

Acquisition of natural language has been shown to fundamentally impact both one's ability to use the first language and the ability to learn subsequent languages later in life. Sign languages offer a unique perspective on this issue because Deaf signers receive access to signed input at varying ages. The majority acquires sign language in (early)…

Purpose: This article examines whether syntactic and vocabulary abilities in American Sign Language (ASL) facilitate 6 categories of language-based analogical reasoning. Method: Data for this study were collected from 267 deaf participants, aged 7;6 (years;months) to 18;5. The data were collected from an ongoing study initially funded by the U.S.…
