Does Vocabulary Help Structure the Mind?

Abstract

Does language reflect the categories of our mind or does it help create them? On one widespread view (cognitive priority), learning a language involves mapping words onto pre-existing categories, leaving little room for language to change the structure of conceptual content. On another view (linguistic priority), conceptual structure is shaped by experience with and use of language. We argue for the latter perspective and present experimental findings showing that nameability – the ease with which a feature can be named – influences problem-solving, category learning, and geometric reasoning. Even subtle manipulations affecting the availability of verbal labels can impact the categories people discover and use. Words do not simply reflect joints of nature, but are used to flexibly carve joints into nature.
