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…

When spoken language (unimodal) bilinguals switch between languages, they must simultaneously inhibit 1 language and activate the other language. Because American Sign Language (ASL)-English (bimodal) bilinguals can switch into and out of code-blends (simultaneous production of a sign and a word), we can tease apart the cost of inhibition (turning…

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…

The purpose of this literature review is to present the arguments in support of conceptualizing deaf children as 'English Learners', to explore the educational implications of such conceptualizations, and to suggest directions for future inquiry. Three ways of interpreting the label 'English Learner' in relationship to deaf children are explored:…

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…

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…

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…

This article presents an analysis of the relationship between sign structure and iconicity in American Sign Language. Historically, linguists have been pressured to downplay the role of form-meaning relationships (iconicity) in signed languages. However, recent inquiries into the role of traditional phonological parameters of signs (handshape,…

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…

This dissertation explores the hypothesis that language processing proceeds in "windows" that correspond to representational units, where sensory signals are integrated according to time-scales that correspond to the rate of the input. To investigate universal mechanisms, a comparison of signed and spoken languages is necessary. Underlying the…
