This paper draws attention to the role of nonverbal communication in the process of simultaneous interpreting. The theoretical basis is provided by the phe-nomenon of audiovisual integration: the ability of the human brain to incorporate both verbal and nonverbal signals into comprehension. Referring to previous works by F. Poyatos, S. Viaggio and K. Seeber, the author attempts to distinguish core functions of nonverbal signals in simultaneous interpreting and to analyse the model of cognitive resource footprint by K. Seeber. Additionally, theoretical and practical ramifications of taking nonverbal signals into consideration for the psychology and quality of work of simultaneous interpreters are pinpointed.
