Among the many traits that define humans, language stands out. For centuries, thinkers like Aristotle have pointed to language as a hallmark of humanity. But as AI models like ChatGPT improve, researchers are digging deeper to see if there are aspects of language that set us apart from machines or other animals.
One area of focus has been the reasoning abilities of language models. Some linguists argue that while these models can mimic language, they lack true understanding. Noted linguist Noam Chomsky expressed this view in a 2023 article, stating that human language is complex and cannot be mastered merely by analyzing large datasets.
However, a recent study challenges this perspective. Researchers Gašper Beguš, Maksymilian Dąbkowski, and Ryan Rhodes put several large language models through a series of linguistic tests. These tests evaluated how well the models could understand and analyze language. Surprisingly, one model outperformed expectations, demonstrating skills similar to a graduate student in linguistics. It was able to parse sentences and deal with complex linguistic features like ambiguity.
This finding is significant. Tom McCoy, a computational linguist at Yale University, noted how crucial it is to understand the capabilities and limitations of these technologies as they become more integrated into our lives. Analyzing language can reveal how closely these models might reason like humans do.
Testing language models is tricky, however. They are trained on vast amounts of text, which can make it easy for them to “cheat.” Researchers designed a special four-part test to evaluate linguistic skills without allowing the models to simply memorize answers. They used techniques like tree diagrams, which break down sentences into components, to assess comprehension effectively.
One of the test’s goals was to evaluate recursion, the ability to embed phrases within sentences. Simple examples include “The sky is blue” and more complex sentences like “Maria wondered if Sam knew that Omar heard that Jane said that the sky is blue.” This skill is a unique feature of human language, opening up endless possibilities for expression.
These ongoing conversations highlight the fine line between human and machine communication. As we move forward, understanding these nuances will be essential in our tech-driven world.
