Neural Dissociation within Language: Lexical Memory is Part of Declarative Memory Grammatical Rules are Processed by Procedural System

Declarative/Procedural Theory: High L2 Experience (L1-Like)

Declarative memory system

Lexicon

Memory store: (at least)

all word-specific information:

-simple words (cat)

-irregulars: (dig-dug)

-complements (hit [direct object])

Language

Grammar

Rule-governed hierarchical and sequential (de-)composition

of complex forms:

-syntax (the cat; NP VP)

-morphology (regulars: walk -ed)

Procedural memory system

Second Language


	The declarative/procedural model claims that Lexicon is dependent on temporal lobe strucutres which also subserve declarative memory; memory for events and associative memory
	on the other hand, grammar is dependent on frontal/basal ganglia circuits which also subserve procedural memory- motor skills and sequence computaitons
