Psycholinguistics and neurolinguistics.

Psycholinguistics is the study of the psychological and neural processes involved in the production, perception, and comprehension of language. It encompasses a wide range of topics, including language acquisition, language processing, language production, and language impairment.

Neurolinguistics is a subfield of psycholinguistics that focuses specifically on the neural basis of language processes. It uses techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to study the brain activity associated with language tasks. Researchers in neurolinguistics aim to understand how the brain processes and represents language, and how this relates to other cognitive functions.

Both psycholinguistics and neurolinguistics draw on insights from a variety of disciplines, including psychology, linguistics, neuroscience, and computer science. They are important for understanding the nature of language and how it is used in communication, as well as for developing new approaches to language education and therapy.
