Abstract: Conscious thinking, a mental activity performing reflection on thinking, facilitates the fundamental transformation of human cognition. It characterizes abilities of recalling past events, recollecting something that is not perceptually present, obtaining mental representation associating with the past, and imagining and evaluating possible future. The reflective consciousness of human being endows us with the ability to reflect on mind and form conceptual thinking. The acquisition of this ability ultimately contributes to language emergence. The motivation of language emergence lies in this unique reflective consciousness of human beings.

Key words: reflective consciousness, conceptual thinking, language emergence, motivation

摘要： 能够对思想进行反思的意识思维促进了人类认知的根本转变。这种意识思维具有回忆反思过去，思考位移事物，获取与过去关联的心理表征，想象、比较和评估可能的未来等方面的能力。人类反思意识的存在赋予人类对思想进行反思并形成概念思维的能力，正是这种能力的获得最终促成语言的产生。人类语言产生的理据就在于人类所独有的这种反思意识。
