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…

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…

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.…

Linguistic descriptions of sign languages are important to the recognition of their linguistic status. These languages are an essential part of the cultural heritage of the communities that create and use them and vital in the education of deaf children. They are also the reference point in language acquisition studies. Ours is exploratory…

Four keynote papers, presented at an international conference on sign language research, discussed general linguistic issues of sign language, psycholinguistics, sociolinguistics, and language acquisition. (CB)

Examines whether specific characteristics of American Sign Language (ASL) syntax affect perceptual processing of the language. Findings support the psychological reality of sentence embedding processes in ASL, further supporting the claim that visually based languages achieve the same functional goals as speech, although with different means. (FL)

Compares the effectiveness of a visual only approach (mouthing and signing) with a simultaneous visual and auditory approach (signing and speaking) in teaching autistic-like children to communicate. Results suggest the simultaneous approach may be superior. In addition, receptive abilities precede expressive. Implications of therapeutic…

Although the linguistic properties of sign languages, and of American Sign Language (ASL) in particular, are beginning to be studied, little work has been done on the functional properties of sign. Four experiments are reported in which signed messages were subjected to varying amounts of disruption using repetitive temporal interruption. Results…

Reviews research on sign language as an instrument of communication and on the psychological validity of sign language. Examines the production of sign language as compared to oral language, perception in sign language, and studies on the role of memory in sign language. (AM)

Psycholinguistic and neurological examination of the use of duality of patterning as a primary criterion for determining if a system is a (signed or spoken) language revealed the existence of duality in processes that facilitate language acquisition. (27 references) (Author/CB)

Explores the operational and conceptual meanings of the iconicity of manual signs and sign languages. Empirical studies related to the operational definition of iconicity in American Sign Language are described, and implications of parallels between iconicity and "stimulus meaningfulness" are discussed in relation to the scientific…

A study tested the hypothesis that manual encoding aids learning in the prelingually deaf. Twenty-four adults who used fingerspelling as their primary means of communication participated in two groups of a paired-associate learning paradigm, using eight study-test trial sequences. Those using fingerspelling showed more recall and a faster learning…

This research focused on the initial stage of language development of a hearing child who was acquiring simultaneously both spoken English and American Sign Language (ASL). The report covers the first phase of the longitudinal research on the child's linguistic development, focusing on early word meanings. The data were collected from the time…

This 24-item annotated bibliography is intended to facilitate introduction to the field of sign language studies. It lists selected published works in English in which sign language is viewed from several different aspects, including: theoretical studies (nos. 1, 5, 6, 19, 20 and 21); works relating Sign to other visual communication systems (nos.…

A framework which considers speech and language as separate entities in a symbiotic relationship is presented, and basic questions are raised concerning how speech and language function together and what their reciprocal effects are. Based on the notion that speech and language are independent, various examples of speech without language and of…
