The term "repair" refers to strategies deployed by language users to resolve breakdowns in communication. In this study, I ask what strategies for conversational repair are deployed, and who takes responsibility for their execution, when a language is used in a small local signing ecology. I focus on signers from a single family within a…

This study undertook iconicity ratings and conducted transparency experiments on Israeli Sign Language (ISL). Experiment 1 compared the iconicity ratings of 520 lexical signs of ten Deaf ISL signers and thirteen hearing non-signers. Ratings were found to be affected by language knowledge, lexical class, and type of iconic mapping, as well as by…

There is a lack of tests available for assessing sign language proficiency among L2 learners. We have therefore developed a sign repetition test, SignRepL2, with a specific focus on the phonological features of signs. This paper describes the two phases of developing this test. In the first phase, content was developed in the form of 50 items with…

Human languages, signed and spoken, can be characterized by the structural patterns they use to associate communicative "forms" with "meanings." One such pattern is paradigmatic morphology, where complex words are built from the systematic use "and re-use" of sub-lexical units. Here, we provide evidence of emergent…

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…

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…

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.…

This study examined facial expressions produced during a British Sign Language (BSL) narrative task (Herman et al., International Journal of Language and Communication Disorders 49(3):343-353, 2014) by typically developing deaf children and deaf children with autism spectrum disorder. The children produced BSL versions of a video story in which…

When learning a second spoken language, cognates, words overlapping in form and meaning with one's native language, help breaking into the language one wishes to acquire. But what happens when the to-be-acquired second language is a sign language? We tested whether hearing nonsigners rely on their gestural repertoire at first exposure to a sign…

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…

Background: Deafness has an adverse impact on children's ability to acquire spoken languages. Signed languages offer a more accessible input for deaf children, but because the vast majority are born to hearing parents who do not sign, their early exposure to sign language is limited. Deaf children as a whole are therefore at high risk of language…

Does spatial language influence how people think about space? To address this question, we observed children who did not know a conventional language, and tested their performance on nonlinguistic spatial tasks. We studied deaf children living in Istanbul whose hearing losses prevented them from acquiring speech and whose hearing parents had not…

This study explores different aspects of the mapping between phonological form and meaning of signs in British Sign Language (BSL) by means of four tasks to measure meaning recognition, form recognition, form recall, and meaning recall. The aim was to investigate whether there is a hierarchy of difficulty for these tasks and, therefore, whether…

Age of acquisition (AoA) effects have been used to support the notion of a critical period for first language acquisition. In this study, we examine AoA effects in deaf British Sign Language (BSL) users via a grammaticality judgment task. When English reading performance and nonverbal IQ are factored out, results show that accuracy of…

In sign language studies, it is generally assumed that a sign can be divided into several phases in time (preparation, stroke, and retraction) and that the stroke contains all of the necessary information. However, this has not been tested empirically. In order to learn where the information truly resides, we present an experiment that…
