The Now-or-Never bottleneck: A fundamental constraint on language

Area of Science:

• Psycholinguistics
• Cognitive Science
• Computational Linguistics

Background:

• The brain faces a constant influx of linguistic information, posing a significant memory challenge.
• Previous material is rapidly overwritten, creating a
• Now-or-Never
• bottleneck for processing.
• Understanding how the brain manages this continuous linguistic input is crucial for cognitive science.

Purpose of the Study:

• To propose a novel framework for understanding language processing, acquisition, and change.
• To explain how the brain overcomes the
• Now-or-Never
• bottleneck in real-time language comprehension.
• To integrate psycholinguistics, language acquisition, and language change theories under a unified model.

Main Methods:

• Theoretical modeling of language processing.
• Analysis of cognitive constraints on linguistic input.
• Conceptual framework development for psycholinguistics.

Main Results:

• Introduction of the
• Chunk-and-Pass
• processing model.
• The model posits that the brain must eagerly compress and recode linguistic input.
• Multilevel linguistic representations and predictive processing are essential for efficient language comprehension.

Conclusions:

• Language acquisition is framed as learning to process, not induce, grammar.
• The
• Chunk-and-Pass
• model provides a cognitive basis for grammaticalization and language evolution.
• This framework bridges psycholinguistics, language acquisition, and linguistic theory.
