Sentence processing in American Sign Language (ASL) was investigated as a function of age of first language acquisition with a timed grammatical judgement task. Participants were 30 adults who were born deaf and first exposed to a fully perceptible language between the ages of birth and 13 years. Stimuli were grammatical and ungrammatical examples of six ASL syntactic structures: simple, negative, agreement verb, wh-question, relative clause and classifier sentences. As delay in exposure to a… 

Age of sign language acquisition has lifelong effect on syntactic preferences in sign language users

Grammatical acceptability ratings and reaction time measures in a group of Deaf signers with early (0–3 years) or later (4–7 years) acquisition of sign language in childhood were examined, whereby the direction of the effect depended on the specific linguistic structure.

Syntactic Priming in American Sign Language

Despite the profound differences between spoken and signed languages in terms of how they are produced and perceived, the psychological representation of sentence structure (as assessed by syntactic priming) operates similarly in sign and speech.

Do Adults Show an Effect of Delayed First Language Acquisition When Calculating Scalar Implicatures?

Comparisons of deaf adults who had either early or late first exposure to their first language (ASL) indicate an overall high performance by late learners, especially when implicatures are not based on conventionalized items, and the creation of a scale based on lexical items can lead to ease in alternative creation that may be advantageously learned early in life.

American Sign Language syntactic and narrative comprehension in skilled and less skilled readers: Bilingual and bimodal evidence for the linguistic basis of reading

ABSTRACT We tested the hypothesis that syntactic and narrative comprehension of a natural sign language can serve as the linguistic basis for skilled reading. Thirty-one adults who were deaf from

Comparing Semantic Fluency in American Sign Language and English.

It is concluded that semantic fluency is sensitive to language dominance and that performance can be compared across the spoken and signed modality, but fingerspelled responses should be included in ASL fluency scores.

The Development of Sensitivity to Grammatical Violations in American Sign Language: Native Versus Nonnative Signers

Factors influencing native and nonnative signers’ syntactic judgment ability in American Sign Language (ASL) were explored for 421 deaf students aged 7;6–18;5. Predictors for syntactic knowledge were

Assessing American Sign Language

This chapter presents an historical account of the progress in the development of measures for assessing first language abilities in ASL and emphasizes that it is important for the purpose of developing assessment to be cognizant of the modality difference between signed and spoken languages.

Acquiring a first language in adolescence: the case of basic word order in American Sign Language

The early syntactic development of adolescent first language learners is studied by examining word order patterns in ASL, suggesting that adolescent L1 learners go through stages similar to child native learners, although this process also appears to be prolonged.

The performance of the subjects who acquired ASL as a first language declined in association with increasing age of acquisition, and effects were most apparent for sentence processing skills related to lexical identification, grammatical acceptability, and memory for sentence meaning.

Looking through phonological shape to lexical meaning: The bottleneck of non-native sign language processing

It is suggested that native signers process lexical structure automatically, such that they can attend to and remember lexical and sentential meaning, in contrast, non-native signers appear to allocate more attention to the task of identifying phonological shapesuch that they have less attention available for retrieval and memory of lexical meaning.
