AI researchers simulate human aphasias to map language model functions

Researchers have developed a novel method to understand the internal workings of language models by simulating aphasias, which are language impairments caused by brain damage in humans. By selectively disabling parts of a model and observing the resulting language deficits, they identified distinct functional roles for different model components, such as attention and feed-forward layers. While some simulated aphasias showed similarities to human conditions, significant qualitative differences suggest that the specific learning and processing mechanisms within LMs lead to unique organizational patterns compared to the human brain.
