Pormpuraawans, we found, arranged time from east to west. That is, seated facing south, time went left to right. When facing north, right to left. When facing east, toward the body, and so on. Of course, we never told any of our participants which direction they faced. The Pormpuraawans not only knew that already, but they also spontaneously used this spatial orientation to construct their representations of time. And many other ways to organize time exist in the world's languages. In Mandarin, the future can be below and the past above. In Aymara, spoken in South America, the future is behind and the past in front.
In addition to space and time, languages also shape how we understand causality. For example, English likes to describe events in terms of agents doing things. English speakers tend to say things like "John broke the vase" even for accidents. Speakers of Spanish or Japanese would be more likely to say "the vase broke itself." Such differences between languages have profound consequences for how their speakers understand events, construct notions of causality and agency, what they remember as eyewitnesses and how much they blame and punish others.
In studies conducted by Caitlin Fausey at Stanford, speakers of English, Spanish and Japanese watched videos of two people popping balloons, breaking eggs and spilling drinks either intentionally or accidentally. Later everyone got a surprise memory test: For each event, can you remember who did it? She discovered a striking cross-linguistic difference in eyewitness memory. Spanish and Japanese speakers did not remember the agents of accidental events as well as did English speakers. Mind you, they remembered the agents of intentional events (for which their language would mention the agent) just fine. But for accidental events, when one wouldn't normally mention the agent in Spanish or Japanese, they didn't encode or remember the agent as well.This confirms something I've always suspected - though, many, many, MANY more studies need to be done before establishing any conclusions. But who knows, maybe socio-linguistics will take off as a discipline in a few years. Plus, advertising agencies would love to have these sort of language-based, psychological insights into consumers across the globe in order to make marketing that much more effective. So between academia and advertising, I'd say we'll see a lot more time, money, and effort thrown into exploring these ideas.
