Hi there! I'm trying to understand a text on the evolution of language. I have some difficulty to get the meaning of the terms 'computational' and 'computational requirements' The context is the following one: It is important to distinguish between questions concerning language as a communicative system and questions concerning the computations underlying this system. [...] There is however an emerging consensus that [...] human and animals share a diversity of important computational and perceptual resources. We need a clear explication of the computational requirements for language. If you have any explanation that can help, i'll be a happier person ;-) Many thanks in advance!
