The human capacity for understanding and producing actions is thought to be highly relevant to the ability to understand and produce language. Some researchers even claim that language is a special and highly structural case of action. The extent to which a mechanism for processing actions also facilitates processing language is thus an interesting question. This conference aims to create conversation among interdisciplinary scholars to unpick the relationship between the two significant capacities of human beings. This conference will focus on a broad range of topics related to the connection between language and action, including (but not limited to): The mechanism of language acquisition and processing The evolution of language Communicative action and nonverbal communication Joint attention and intention detection Voluntary and involuntary actions Cognitive requirements for language and for non-communicative action Mental representation/knowledge of language Interpersonal analysis of language and action The comparison between human and nonhuman primates Practical reasoning and action understanding Action/Language analysis in Asian tradition
