Lecture 2: Gesture’s Role in Creating and Learning Language
Imagine a child who has never seen or heard any language at all. Would such a child be able to invent a language on her own? Despite what one might guess, the answer to this question is “yes”. I describe children who are congenitally deaf and cannot learn the spoken language that surrounds them. In addition, they have not yet been exposed to sign language, either by their hearing parents or their oral schools. Nevertheless, the children use their hands to communicate––they gesture––and those gestures take on many of the forms and functions of language. The properties of language that we find in the deaf children’s gestures are just those properties that do not need to be handed down from generation to generation, but can be reinvented by a child de novo. They are the resilient properties of language, properties that all children, deaf or hearing, come to language-learning ready to develop.
In contrast to these deaf children who are inventing a language with their hands, hearing children are learning language from a linguistic model. But they too produce gestures. Indeed, young hearing children often use gesture to communicate before they use words. Interestingly, changes in a child’s gestures not only predate but also predict changes in the child’s early language, suggesting that gesture may be playing a role in the language-learning process. For example, gesture could influence language-learning by eliciting from adults the kinds of words and sentences that the child needs to hear in order to take the next linguistic step. Gesture thus not only reflects the language-learning stages through which a young child passes––it may play a role in language-learning itself.
第二講:手勢與語言創造和語言學習
想像從未接觸過或聽過任何語言的孩子,他們能夠自己創造語言嗎?這問題的答案是肯定的。這次演講談論先天耳聾而無法學習周遭口語的孩子,這些孩童未曾透過有聽力的父母或者口語學校接觸過手語,但他們會用雙手來溝通——他們使用手勢,而這些手勢具有許多語言的形式和功能。聾啞兒童的手勢所呈現的語言特性正是那些不需要代代相傳的特性,經由孩子重塑而展現語言的適應力,是所有兒童,無論聾啞還是具有聽力,準備語言學習而需發展的特性。
相較於用手創造語言的聾啞孩子,有聽力的兒童是從語言模型中學習語言,而他們也使用手勢。年幼的聽覺兒童確實在使用詞彙之前經常使用手勢進行溝通,有趣的是孩童手勢的變化不僅早於語言並且預測早期的語言發展,顯示手勢在語言學習過程中可具有影響,例如手勢可從大人引出孩子需要聽到的單字和句子,再進行接下來的語言產出。因此,手勢不僅反映了幼兒所經歷的語言學習階段,也影響語言學習。
