ASL Simultaneity Grammar
1996 - 2002
The period is characterized by a shift toward integrating manual and nonmanual components as inseparable pillars of American Sign Language grammar, with nonmanual markers, body posture, and discourse cues shaping syntactic structure and meaning, including negation, passives, and contrast. Researchers also emphasize variation and dialect differences across Deaf communities, African American and White signing, and spontaneous sign systems across cultures, highlighting how regional practices influence lexical distribution and sign formation. Acquisition and development studies map how learners acquire handshape, movement, negation, and literacy-related skills, linking ASL development to English literacy, while neural and cognitive processing work compares modalities, working memory, and visual-language processing under varied sensory conditions. The sociocultural and educational dimensions are foregrounded, examining Deaf-World identity, bilingual education frameworks, and cross-cultural sign systems as integral to understanding ASL as language and culture.
• Integrates manual and nonmanual components as core grammar in American Sign Language (ASL), showing nonmanual markers, body posture, and discourse cues shape ASL syntax and meaning, including negation, passives, and contrast [20], [13], [11], [15].
• Explores variation and dialectal differences in American Sign Language (ASL) across communities, including DEAF variation, lexical variation among African American and White signing, and spontaneous sign systems across cultures [3], [8], [16].
• Focuses on acquisition and development in American Sign Language (ASL), mapping how learners acquire handshape, movement, negation, and literacy-related skills, including relationships to English literacy [6], [17], [20], [4].
• Addresses neural and cognitive processing in American Sign Language (ASL), comparing modalities, working memory, neural systems, and visual-language processing under neglect or sensory conditions [7], [19], [18], [10].
• Examines sociocultural and educational dimensions of American Sign Language (ASL) as language and culture, including Deaf-World identity, bilingual education frameworks, and cross-cultural sign systems [2], [5], [4], [16].
