Gesture

手势是一种非言语交际或非言语交际的形式，在这种形式中，可见的身体动作传达特定的信息，或代替言语，或与言语结合。手势包括手、脸或身体其他部位的动作。手势不同于身体上的非语言交流，而身体上的非语言交流并不传达特定的信息，比如纯粹的表达性表达、空间性表达或共同注意力的表达。[1]手势可以让人们交流各种各样的感觉和想法，从轻蔑和敌意到赞同和喜爱，通常还可以在说话的时候加上肢体语言。手势处理发生在大脑的某些区域，如布洛卡区和韦尼克区，这些区域用于语言和手语。事实上，一些学者认为语言是从早期的手势系统进化而来的。[3]中国英语学习网语言是从手势进化而来的理论，称为手势理论，可以追溯到18世纪哲学家兼神父阿贝·德·康狄拉克的著作。1973年，当代人类学家戈登·w·休斯(Gordon W. Hewes)在关于语言起源的讨论中重新提出了这一理论

A gesture is a form of non-verbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Gestures include movement of the hands, face, or other parts of the body. Gestures differ from physical non-verbal communication that does not communicate specific messages, such as purely expressive displays, proxemics, or displays of joint attention.[1] Gestures allow individuals to communicate a variety of feelings and thoughts, from contempt and hostility to approval and affection, often together with body language in addition to words when they speak.Gesture processing takes place in areas of the brain such as Broca's and Wernicke's areas, which are used by speech and sign language.[2] In fact, language is thought by some scholars to have evolved in Homo sapiens from an earlier system consisting of manual gestures.[3] The theory that language evolved from manual gestures, termed Gestural Theory, dates back to the work of 18th-century philosopher and priest Abbé de Condillac, and has been revived by contemporary anthropologist Gordon W. Hewes, in 1973, as part of a discussion on the origin of language
