A Working Memory Model of Sentence Processing as Binding Morphemes to Syntactic Positions.

Area of Science:

• Cognitive Science
• Psycholinguistics
• Computational Linguistics

Background:

• Sentence processing requires mapping words to their grammatical roles.
• Working memory models explain how this information is temporarily stored and manipulated.
• Existing models account for some memory interference effects in language.

Purpose of the Study:

• To propose a unified model of working memory for linguistic processing.
• To explain the encoding, maintenance, and retrieval of morpheme-position bindings.
• To account for both similarity-based and item distortion interference effects.

Main Methods:

• Developing a computational model based on "serial-order-in-a-box" (SOB) principles.
• Simulating the binding of lexical items to syntactic positions in working memory.
• Analyzing simulation results to identify patterns of memory interference.

Main Results:

• The model successfully captures similarity-based interference effects.
• The model also accounts for item distortion effects in memory recall.
• These findings suggest an associative memory architecture underlies linguistic computation.

Conclusions:

• The proposed model offers a unified explanation for key interference effects in sentence processing.
• It highlights the role of associative memory in managing linguistic information.
• This work advances our understanding of the cognitive mechanisms of language comprehension.
