What is a key consideration when studying language development in sign language users compared to spoken language users?

• A. Underlying processes are similar but measurement must account for modality differences
• B. Sign language development does not involve grammar
• C. Sign language is always easier to learn than spoken language
• D. Sign language users do not exhibit typical milestones

Answer: (B)

The main idea is that language development in sign language users follows the same kinds of cognitive and linguistic processes as in spoken language, but the way we observe and measure progress must fit the visual-manual modality. Sign languages have full grammar—morphology, syntax, and complex systems like sign order, spatial grammar, and nonmanual signals (facial expressions, head and body movements) that carry grammatical meaning. Because of these modality differences, standard assessments and milestones created for spoken language don’t always capture early development in sign language learners. For example, children may show rapid growth in signable vocabulary and in acquiring complex spatial constructions long before equivalent spoken-word milestones appear, and researchers must tailor measures to track signs, classifiers, and nonmanual grammar rather than spoken words alone. The claim that sign language development lacks grammar is incorrect because sign languages demonstrate rich, rule-governed structure just like spoken languages. The idea that sign language is always easier to learn ignores theReality that any language has its own complexities, and sign languages require mastering nonmanual signs and spatial grammar just as spoken languages require mastering auditory phonology and syntax. Finally, sign language users do show typical developmental milestones—though the expressions may look different due to modality—so assuming they don’t is not accurate.
