Language Processing
The cognitive and computational mechanisms involved in understanding, producing, and acquiring language, spanning multiple levels from sound perception to meaning construction.
Overview
Language processing encompasses the complex mental operations that enable humans and machines to comprehend, generate, and manipulate language. This fundamental cognitive capacity involves multiple interconnected systems working across different levels of linguistic structure, from basic phonetics to complex semantics.
Levels of Processing
Phonological Processing
- Sound pattern recognition
- phoneme discrimination
- Prosodic pattern analysis
- Connection to auditory perception
Syntactic Processing
- Parsing grammatical structures
- Application of syntax rules
- Processing of universal grammar principles
- Structural ambiguity resolution
Semantic Processing
- Word meaning extraction
- conceptual representation
- Context integration
- metaphor comprehension
Pragmatic Processing
- Understanding speaker intentions
- social cognition integration
- Cultural context interpretation
- discourse analysis
Neural Basis
The brain's language network includes:
- Broca's area - speech production and syntax
