We discuss the causative-inchoative alternation in Turkish Sign Language (Türk Isaret Dili -- TID), and the age of acquisition effects on multi-predicate, complex constructions that are observed in both causative and inchoative events. We present a picture-description task performed by 24 adult signers, half of which were exposed to TID from birth…

This article discusses the function of a particular feature of sign language--mouth action--as it is expressed in various discourse contexts. Specifically, we examine forms of mouthing and mouth gesture as they are used in signed narrative and expository texts, highlighting the signers' choices during the production of these two text types. We…

This study aimed to explore emotional regulation, alexithymia, and interpersonal relations in a Spanish sample of 146 adult deaf participants and 146 typical hearing participants. For the deaf sample, the associations between type of language used and the above variables were also analyzed. Results showed that deaf participants scored higher on…

Between 30 and 50% of individuals with Autism Spectrum Disorder (ASD) do not develop vocal language deemed functionally acceptable to meet their daily communication needs. As a result, individuals with ASD may require intervention alternatives to vocal speech, such as augmentative and alternative communication (AAC). However, very little is known…

While societies have become increasingly dependent on both internet- and information technology-based knowledge retrieval and applications and as social media has become an inextricable aspect of most people's daily lives, a keen interest has emerged regarding the impact that these technologies have on Deaf people's lives. This article describes…

Background: Staff may encourage individuals with intellectual disabilities to use manual signs by modelling its use, but implementing key word signing during daily activities can be demanding. Method: Staff's use of manual signs was observed in four special schools and four day centres for adults with intellectual disabilities during communicative…

Purpose: This investigation focused on generalization of outcomes for auditory training by examining the effects of task and/or talker overlap between training and at test. Method: Adults with hearing loss completed 12 hr of meaning-oriented auditory training and were placed in a group that trained on either multiple talkers or a single talker. A…

Recent evidence demonstrates that pictures corresponding to iconic signs are named faster than pictures corresponding to non-iconic signs. The present study investigates the locus of the iconicity advantage in hearing bimodal bilinguals. A naming experiment with iconic and non-iconic pictures in Italian Sign Language (LIS) was conducted. Bimodal…

The purpose of the study was to uncover and describe psycholinguistic and sociocognitive factors facilitating effective reading by signing adults who are profoundly deaf and do not use hearing technology. The sample comprised four groups, each consisting of 15 adults, for a total of 60 participants. The four groups were "deaf…

Students acquiring American Sign Language (ASL) as a second language (L2) struggle with fingerspelling comprehension more than skilled signers. These L2 learners might be attempting to perceive and comprehend fingerspelling in a way that is different from native signers, which could negatively impact their ability to comprehend fingerspelling.…

In Scandinavia and some other countries, a bilingual-bicultural approach to deaf education was celebrated in national programs from the mid-1980s until the broad popularity of cochlear implantation in middle 2000s created a shift back to an emphasis on spoken language for many deaf children. At the same time, only a few studies evaluated the…

Facial expressions in sign language carry a variety of communicative features. While emotion can modulate a spoken utterance through changes in intonation, duration and intensity, in sign language specific facial expressions presented concurrently with a manual sign perform this function. When deaf adult signers cannot see facial features, their…

Language acquisition involves learning not only grammatical rules and a lexicon but also what people are intending to convey with their utterances: the semantic/pragmatic component of language. In this article we separate the contributions of linguistic development and cognitive maturity to the acquisition of the semantic/pragmatic component of…

Two studies addressed key theoretical debates in theory of mind (ToM) development by comparing (a) deaf native signers (n = 18), (b) deaf late signers (n = 59), and (c) age-matched hearing persons (n = 74) in childhood (Study 1: n = 81) and adulthood (Study 2: n = 70) on tests of first- and second-order false belief and conversational sarcasm.…

What abilities are entailed in being numerate? Certainly, one is the ability to hold the exact quantity of a set in mind, even as it changes, and even after its members can no longer be perceived. Is counting language necessary to track and reproduce exact quantities? Previous work with speakers of languages that lack number words involved…
