How sign language users learn intonation - 2 views

Lara Cowell on 11 Oct 15A spoken language is more than just words and sounds. Speakers use changes in pitch and rhythm, known as prosody, to provide emphasis, show emotion, and otherwise add meaning to what they say. But a language does not need to be spoken to have prosody: sign languages, such as American Sign Language (ASL), use movements, pauses and facial expressions to achieve the same goals. In a study appearing in the September 2015 issue of Language, three linguists look at intonation (a key part of prosody) in ASL and find that native ASL signers learn intonation in much the same way that users of spoken languages do. Children learning ASL acquired prosodic features in three stages of "appearance, reorganization, and mastery": accurately replicating their use in simpler contexts, attempting unsuccessfully at first to use them in more challenging contexts, then using them accurately in all contexts as they fully learn the rules of prosody. Previous research has shown that native learners of spoken languages acquire intonation following a similar pattern.
