when your pet cat comes home and stands at your feet calling meow, you are likely to understand this message as relating to that immediate time and place. if you ask your cat where it has been and what it was doing, you’ll probably get the same meow response. animal communication seems to be designed exclusively for this moment, here and now. it can’ effectively be used to relate events that are far removed in time and place. when your dog says grrr, it means grrr, right now, because dogs don’t seem to be capable of communicating grrr, last night, over in the park. in contrast, human language users are normally capable of producing messages equal to grrr, last night, over in the park, and then going on to say in fact, i’l be going back tomorrow. humans can refer to past and future time. therefore, language users are able to talk about things and events which aren’t present in the immediate environment.
