Lexico-syntactic constraints influence verbal working memory in sentence-like lists

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Verbal working memory (VWM) is crucial for language processing.
• The language emergent perspective suggests linguistic knowledge influences VWM.
• Lexico-syntactic constraints, like grammar rules, are key to language.

Purpose of the Study:

• To investigate if lexico-syntactic constraints impact VWM item and order memory.
• To test predictions from the language emergent perspective on VWM.

Main Methods:

• Three experiments were conducted using dative-like sentences and lists.
• Participants recalled words after manipulations of part of speech, verb biases, and noun animacy.
• Performance was measured by word recall accuracy in correct positions.

Main Results:

• Recall accuracy improved when verbs were used over nouns in the verb position.
• Dative verbs enhanced recall compared to intransitive verbs.
• Animate nouns in the subject position improved recall over inanimate nouns.

Conclusions:

• Lexico-syntactic constraints significantly influence verbal working memory.
• Linguistic context plays a vital role in both item and order memory.
• Findings support the language emergent perspective on VWM.
