摘要：Language is usually considered as a set of arbitrary symbols that convey subjacent internal concepts. According to this traditional approach words are only words, mere external signals of internal processes. In contrast, we propose that Words are social Tools (WAT). This view allows us address one of the critical problems embodied views face, the problem of how abstract words are acquired and represented. Indeed, we argue that the role of sensorimotor engagement varies depending on the considered domain. In the case of the acquisition of concrete word meanings, categories are grounded primarily in perception and action systems, and linguistic labels contribute in constraining the boundaries of grounded categories. In the use of abstract words, the opposite mechanism might be adopted. Abstract words are more difficult to learn because they activate a much more complex set of situations, objects, human activities and so on. The linguistic labels help us group and assemble this variety of experiences. In addition, diversity of languages has more of an impact on abstract words as opposed to concrete word meaning.
