What is the difference between language and thought and how does this impact LLM's?

Question

Accepted Answer

The difference between language and thought is a nuanced topic explored in the podcast. Language is described as a communication system for conveying meaning, whereas thinking involves the creation of meaning itself ([[01:26:30]]). This distinction emphasizes that language is a tool for expressing thoughts but is not synonymous with thought itself ([[01:26:36]]).

It is noted that language comprehension and thought processes are separate in the brain. For example, certain tasks that do not involve words or word combinations do not activate the language network in the brain, highlighting that thinking can occur without the use of language ([[01:38:07]] to [[01:38:24]]). This is further supported by evidence showing that individuals with language impairments can still perform tasks like math, suggesting that thinking does not rely solely on language ([[01:39:32]] to [[01:39:58]]).

The podcast also delves into the implications for large language models (LLMs). A fascinating point is that certain complex linguistic structures, such as center embeddings, are challenging for both humans and LLMs to produce, which connects to the broader discussion of dependency grammar frameworks in language processing ([[01:53:15]] to [[01:53:28]]).

To summarize:

- **Language vs. Thought**: Language is a tool for communication, whereas thought is the generation of meaning ([[01:26:30]] to [[01:26:36]]).

- **Brain Activity**: Language and thought processes are distinct in the brain; language tasks activate specific networks, whereas non-language tasks do not ([[01:38:07]] to [[01:38:24]], [[01:39:32]] to [[01:39:58]]).

- **Implications for LLMs**: The difficulty LLMs face with certain linguistic structures reflects the complexity of human language processing ([[01:53:15]] to [[01:53:28]]).
