To fully acquire a language, children absorb roughly 12.5 million bits of information by the time they're 18, assistant psychology professor Steven Piantadosi and his former graduate student Frank Mollica at the University of Rochester have calculated. The study challenges theories that language acquisition occurs effortlessly, due to hardwiring, as well as notions that robots could easily master it. "A lot of research on language learning focuses on syntax, like word order," Professor Piantadosi says. "But our study shows that syntax represents just a tiny piece of language learning, and that the main difficulty has got to be in learning what so many words mean. ... When you think about a child having to remember millions of zeroes and ones -- in language -- that says they must have really pretty impressive learning mechanisms."
