时空隐喻的心理现实性:手势和手语的视角

The Psychological Reality of Spatial Metaphors for Time——Evidence form Gesture and Sign Language

早期有关时空隐喻表征心理现实性的研究因囿于有声语言而饱受批评,近年来兴起的手势和手语研究为该问题的证明提供了新的视角和证据。一方面,手势在三个空间维度上均可形成时空隐喻,有力地回应了反对派对概念隐喻理论在语言和概念层面循环论证的质疑;另一方面,手语空间运用的独特性以及文化图式的复杂性,导致其时空隐喻表现形式更为多样,为该领域研究提供了更加丰富的类型学证据。未来研究还应当注意心理学、语言学以及民族学等多学科的交汇融合,建立起概括力更强和系统性更完整的理论框架,将口语、手势和手语同时囊括其中。

Spatial metaphors for time are prevalent in most languages and cultures in the world. According to Conceptual Metaphor Theory （CMT, Lakoff ＆ Johnson, 1980）, metaphor offers a way to understand an abstract domain （e.g. time） by utilizing corresponding knowledge from a better- understood, more concrete experience （e.g. space）. Yet, criticisms from the scholars both within and outside cognitive sciences have never stopped since the birth of CMT, especially for its psychological reality. In other words, the linguistic data （oral speech and written language） is always used as both the predictor of the conceptual mappings and the predicted results. In order to respond to the criticisms of CMT, an emerging synthesis of gesture and signed language has been proposed to address this issue. Human communication can be performed verbally and/or nonverbally. For a long time, gestures have been only considered to be meaningless hand waving, or to bear fixed form and formulaic meanings in a culture from a semiotic perspective. In recent years, gestures and speech are considered to be parts of a single psychological structure and share the same computational and psychological origin. When people talk about time, there are some accompanied hand movements, which are often called temporal gestures. A number of recent studies have focused on temporal gestures in different cultural contexts, showing that temporal gestures are strongly shaped by cultural practices and artifacts. For humans, the ability to communicate and use language is instantiated not only in the vocal modality but also in the visual modality. Sign languages are typically articulated in the three-dimensional space by deaf people. In the case of sign languages, different devices （e.g. lexical expressions, grammatical means and non-manual features） can be used in the expressions of temporal notions, Many studies in sign languages have provided supporting evidence for the existence of time line and its important role in the creation of temporal expressions. It means that signers may automatically activate the mental timeline when processing temporal linguistic information. On one hand, signers can use real space to create temporal references, in which the metaphorical association of locations in space represents different points of time. On the other hand, he or she can also directly use a lexical unit to refer to that temporal dimension without turning to deixis. Compelling evidence has shown that our concept of time is organized metaphorically in terms of space. Recent development brings a welcome widening of the perspective of the time metaphor research and starts to reap the benefits of the broad range of methods available in cognitive science. If one wants to prove that conceptual metaphors are conceptual thinking rather than only linguistic decoration, alternative evidence beyond linguistic data for their psychological reality is required, since both of sign and co-speech gesture exploit richness of the manual-visual modality to spatialize temporal concepts. The study of more signed languages, in relation to the co-speech temporal gestures, can provide rich psychological evidence to clarify the origins and transmission of spatial representations of time.
