The visual-manual modality of sign languages renders them a unique test case for language acquisition and processing theories. In this commentary the authors describe evidence from signed languages, and ask whether it is consistent with Ambridge's proposal. The evidence includes recent research on collocations in American Sign Language that reveal…

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…

Nonsigners viewing sign language are sometimes able to guess the meaning of signs by relying on the overt connection between form and meaning, or iconicity (cf. Ortega, Özyürek, & Peeters, 2020; Strickland et al., 2015). One word class in sign languages that appears to be highly iconic is classifiers: verb-like signs that can refer to location…

The current study investigated the mechanism of language switching in unbalanced visual unimodal bilinguals as well as balanced and unbalanced bimodal bilinguals during a picture naming task. All three groups exhibited significant switch costs across two languages, with symmetrical switch cost in balanced bimodal bilinguals and asymmetrical switch…

Is the right to sign language only the right to a minority language? Holding a capability (not a disability) approach, and building on the psycholinguistic literature on sign language acquisition, I make the point that this right is of a stronger nature, since only sign languages can guarantee that each deaf child will properly develop the…

Understanding how language modality (i.e., signed vs. spoken) affects second language outcomes in hearing adults is important both theoretically and pedagogically, as it can determine the specificity of second language (L2) theory and inform how best to teach a language that uses a new modality. The present study investigated which…

This article expands the study of other-initiated repair in conversation--when one party signals a problem with producing or perceiving another's turn at talk--into the domain of visual bodily behavior. It presents one primary cross-linguistic finding about the timing of visual bodily behavior in repair sequences: if the party who initiates repair…

We used fluency tasks to investigate lexical organisation in Deaf adults who use British sign language (BSL). The number of responses produced to semantic categories did not differ from reports in spoken languages. However, there was considerable variability in the number of responses across phonological categories, and some signers had difficulty…

Bilinguals sometimes outperform age-matched monolinguals on non-language tasks involving cognitive control. But the bilingual advantage is not consistently found in every experiment and may reflect specific attributes of the bilinguals tested. The goal of this dissertation was to determine if the way in which bilinguals use language, specifically…

Language is proposed to have developed atop the human analog of the macaque mirror neuron system for action perception and production [Arbib M.A. 2005. From monkey-like action recognition to human language: An evolutionary framework for neurolinguistics (with commentaries and author's response). "Behavioral and Brain Sciences, 28", 105-167; Arbib…

High illiteracy rates among the Argentine deaf population, even after long years of schooling, point to the need to revise certain approaches to deaf literacy, particularly in school settings. Qualitative change in deaf literacy requires the use of multiple conceptual tools if learners are to be able to tackle its complexity without reductionism…

New positive attitudes towards language interaction in the realm of bilingualism open new horizons for sign bilingual education. Plaza-Pust and Morales-Lopez have innovatively reconceptualised a new cross-disciplinary approach to sign bilingualism, based on both sociolinguistics and psycholinguistics. According to this framework, cross-modal…

Investigates sign learning as a function of sign translucency (ease of relating a sign to its referents) and referential concreteness. Naive sign learners attempted to learn a list of sign-referent pairs. Signs high in translucency and referents high in concreteness facilitated learning; low levels of each variable inhibited learning. (Author/PJM)

Reviews methodologies of sign language studies with chimpanzees and compares major findings of those studies with studies of human children. Considers relevance of input conditions for language acquisition, evidence used to demonstrate linguistic achievements, and application of rigorous testing procedures in developmental psycholinguistics.…

Describes how a laboratory phonologist might investigate three issues in the analysis of the prosody of signed languages: the internal structure, if any, of the signed syllable, the realization of lexical and phrasal prominence, and the marking of edges. Proposes to investigate the internal structure of the syllable by adapting psycholinguistic…
