Language is a magical human ability to transmit complex thoughts across space and time. Through sounds and air vibrations, our brains transform these into ideas, allowing us to share knowledge and even create novel concepts in others' minds.
With about 7,000 languages globally, each with unique sounds, vocabularies, and structures, the question arises: Does language shape thought? This debate has a long history, with figures like Charlemagne believing language crafts reality, while Shakespeare suggested it doesn't. Recent scientific data from psycholinguistics now offers insights into this age-old question.
The Kuuk Thaayorre people of Australia use cardinal directions (north, south, east, west) for everything instead of 'left' and 'right'. This linguistic practice leads to superior orientation skills, challenging previous notions about human spatial abilities. This demonstrates how language can train humans to achieve remarkable cognitive feats.
The way we organize time is influenced by our language. English speakers might organize time from left to right, while Hebrew or Arabic speakers might go from right to left. For the Kuuk Thaayorre, time is anchored to the landscape (east to west), rather than the individual's body, showcasing a dramatically different cognitive framework for time.
Languages also differ in their numerical systems. Some languages lack exact number words, which impacts speakers' ability to count and keep track of precise quantities. Having count words in a language is a 'linguistic trick' that opens up the entire realm of mathematics.
Languages divide the color spectrum differently. Russian, for instance, distinguishes between light blue ('goluboy') and dark blue ('siniy') with separate words, unlike English. This linguistic distinction makes Russian speakers faster at discriminating between these shades, and their brains show a 'surprised' reaction when crossing the linguistic color boundary, which English speakers do not.
Many languages assign grammatical genders to nouns. These genders influence how speakers perceive objects. For example, German speakers, where 'bridge' is feminine, describe bridges with words like 'beautiful' and 'elegant,' while Spanish speakers, where 'bridge' is masculine, use words like 'strong' or 'long.'
Languages also shape how events are described, particularly accidents. English focuses on the agent ('He broke the vase'), while in Spanish, one might say 'The vase broke itself.' This impacts memory and blame; English speakers remember who did it, while Spanish speakers focus on the accident's intention. This has implications for eyewitness testimony and assigning punishment.
Language profoundly shapes thought in various ways: influencing concepts of space and time, enabling numerical and mathematical understanding, affecting basic perceptual decisions like color discrimination, broadly impacting how we think about anything named by a noun, and even influencing important ideas like blame and punishment.
Linguistic diversity reveals the human mind's ingenuity and flexibility, showcasing 7,000 distinct cognitive universes. However, this diversity is rapidly declining, with one language lost per week. The majority of what we know about the human mind is based on a narrow subset of the population (English-speaking undergraduates), highlighting the need for broader scientific study.
Speakers of different languages think differently, and our own language profoundly shapes our thought processes. This understanding prompts us to question why we think the way we do, how we could think differently, and what thoughts we wish to create.
