This study investigated visual statistical learning (VSL) in 24 deaf signers and 24 hearing non-signers. Previous research with hearing individuals suggests that SL mechanisms support literacy. Our first goal was to assess whether VSL was associated with reading ability in deaf individuals, and whether this relation was sustained by a link between…

Cumulating evidence suggests that the establishment of high-quality phonological representations is the "cognitive precursor" that facilitates the acquisition of language (spoken, signed, and written). The authors present two studies that contrast the nature of bilingual profoundly deaf children's phonological representations derived…

Purpose: The purpose of this study was to report how "verbal rehearsal speed" (VRS), a form of covert speech used to maintain verbal information in working memory, and another verbal processing speed measure, perceptual encoding speed, are related to 3 domains of executive function (EF) at risk in cochlear implant (CI) users: verbal…

Effective literacy education in deaf students calls for psycholinguistic research revealing the cognitive and neural mechanisms underlying their written language processing. When learning a written language, deaf students are often instructed to sign out printed text. The present fMRI study was intended to reveal the neural substrates associated…

Lexical access is concerned with how the spoken or visual input of language is projected onto the mental representations of lexical forms. To date, most theories of lexical access have been based almost exclusively on studies of spoken languages and/or orthographic representations of spoken languages. Relatively few studies have examined how…

It is known that in American Sign Language (ASL) span is shorter than in English, but this discrepancy has never been systematically investigated using other pairs of signed and spoken languages. This finding is at odds with results showing that short-term memory (STM) for signs has an internal organization similar to STM for words. Moreover, some…

The working memory model for Ease of Language Understanding (ELU) predicts that processing differences between language modalities emerge when cognitive demands are explicit. This prediction was tested in three working memory experiments with participants who were Deaf Signers (DS), Hearing Signers (HS), or Hearing Nonsigners (HN). Easily nameable…

The placement of laughter in the speech of hearing individuals is not random but "punctuates" speech, occurring during pauses and at phrase boundaries where punctuation would be placed in a transcript of a conversation. For speakers, language is dominant in the competition for the vocal tract since laughter seldom interrupts spoken phrases. For…

The study involving 56 hearing and 24 deaf children (9-11 years old) sought evidence of language knowledge in deaf children extending beyond formal instruction, and consequently suggestive of a functional generative language system. (Author/SBH)

This paper discusses the results of a study of 27 college students with deafness that investigated whether cognitive processes are modality dependent in individuals with deafness. The experiment included two separate parts, one composed of shape trials and the other composed of word trials. An initial stimulus was shown on a computer screen for…

Six stages of a total communication intervention strategy to improve question comprehension skills in a profoundly hearing impaired subject (age 12) are described: (1) enhancing emergent skills; (2) manipulating wh-question forms; (3) increasing flexibility in wh-question responses; (4) developing questions in conversational context; (5) prompting…

Two experiments were conducted on the influence of language mode (print or sign) and syntax (English or American Sign Language) on recall, preference, and comprehension. Prelingual deaf individuals' visual orientation produced a sign-based encoding system that responded to American Sign Language as a familiar language. (Author/BS)

To determine if imagery mediates memory for signs and words, 80 sign-language-fluent Ss -- half of whom were congenitally deaf and half of whom were normal-hearing -- were tested by varying the imagery values of stimuli. The relative efficacy of word and sign codes in processing and retrieving information was studied by systematically varying the…
