Knowledge of Language Transfers From Speech to Sign: Evidence From Doubling.

Does knowledge of language transfer across language modalities? For example, can speakers who have had no sign language experience spontaneously project grammatical principles of English to American Sign Language (ASL) signs? To address this question, here, we explore a grammatical illusion. Using spoken language, we first show that a single word with doubling (e.g.

ANCHORING is amodal: Evidence from a signed language.

Across languages, certain linguistic forms are systematically preferred to others (e.g. bla > lba).

The double identity of doubling: Evidence for the phonology-morphology split.

Duality of patterning, is, by hypothesis, a universal design feature of language. Every language constructs words from meaningful units (morphemes), which, in turn, are comprised of meaningless phonological elements (e.g.

The double identity of linguistic doubling.

Does knowledge of language consist of abstract principles, or is it fully embodied in the sensorimotor system? To address this question, we investigate the double identity of doubling (e.g., slaflaf, or generally, XX; where X stands for a phonological constituent).
