A small number of behavioural studies, spread over four decades, report that non-human animals such as bees and pigeons, but also macaques, baboons, and chimpanzees, struggle to reverse the associations that they learned in one direction.

Does that mean that chimps who learn to sign have to learn everything twice (once to understand the signs used by others, and again to produce the signs themselves)?
