Memory limitations and chunking are variable and cannot explain language structure

Abstract

Both the Now-or-Never bottleneck and the chunking mechanisms hypothesized to cope with it are more variable than Christiansen & Chater (C&C) suggest. These constructs are, therefore, too weak to support C&C's claims for the nature of language. Key aspects of the hierarchical nature of language instead arise from the nature of sequencing of subgoals during utterance planning in language production.
