On the role of sign order and morphological structure in memory for American Sign Language sentences

Temas

Detalles

Sentence processing in a visual—gestural language was investigated by testing signers recognition for American Sign Language (ASL) sentences. Using a continuous recognition paradigm, sign order and structural changes that altered the meaning of a sentence were noticed at both immediate and delayed (45 seconds) test intervals. Sign order and structural changes that resulted in a paraphrase of an earlier-occurring sentence were noticed only with immediate testing. These results indicate that signers decompose a complex sign into its lexical and inflectional components during sentence comprehension and remember the meaning expressed by these components rather than remembering the exact sign structure.
