Linguistics & Cognitive Science Glossary
Essential concepts in applied linguistics, second language acquisition (SLA), and cognitive memory research that guide the design of nthoughts' streak-free speaking workspace.
Fossilisation (Language Acquisition)
The process whereby non-standard linguistic features (grammar errors or pronunciation habits) become permanently established in an adult learner's speech despite continued exposure to the language.
Spaced Repetition System (SRS)
A learning technique that incorporates increasing intervals of time between subsequent review of previously learned material in order to exploit the psychological spacing effect.
Active Recall (Testing Effect)
The principle that actively stimulating memory retrieval during the learning process strengthens neural pathways far more than passive review or rereading.
Code-Switching & Linguistic Interference
The alternating use of two or more languages or linguistic varieties within a single conversation, social setting, or thought process.
CEFR Language Proficiency Framework
The Common European Framework of Reference for Languages, an international standard for describing language ability across six reference levels from A1 (beginner) to C2 (mastery).
Minimal Pairs
Pairs of words that differ by only one single phonological element (sound) and have distinct meanings, used to train phonetic perception and pronunciation accuracy.
Phoneme
The smallest distinct unit of sound in a language that can distinguish one word from another.
Automaticity in Speech Production
The ability to retrieve and produce linguistic structures with minimal conscious cognitive effort, allowing working memory to focus on message content rather than syntax rules.
