Study Notes
Neurolinguistics
- Neurolinguistics is the science that studies the parts of the brain directly related to language development and production.
- The field originated from aphasiology studies by Broca (1864) and Wernicke (1874), who identified brain regions associated with language development.
- Broca's area is associated with language production problems, characterized by halting speech and difficulty with function words.
- Wernicke's area is associated with language comprehension problems, characterized by grammatically fluent but semantically inappropriate or incoherent language.
- Modern non-invasive techniques allow neurolinguists to observe the brain in action, tracking brain activity and magnetic fields.
Psycholinguistics
- Psycholinguistics is an interdisciplinary field that studies language-related aspects of brain activity, including L1 and L2 acquisition, language comprehension, and processing.
- The field aims to understand how we manage to speak, understand, read, and write, and how brain activity enables language processing.
- Psycholinguistics draws on insights from psychology, linguistics, neurolinguistics, and other fields.
Metalinguistics
- The prefix 'meta-' originally meant 'what is beyond', but now means 'x about x'.
- Metalinguistics is the study of language and speech as a window to the nature and structure of the human mind.
Pragmatics
- Pragmatics studies how context and previous knowledge influence, determine, and contribute to meaning.
- The field distinguishes between a sentence (an abstract linguistic entity) and an utterance (a complete meaning that takes into account context, speaker's intent, etc.).
