Noun Sequence Statistics Affect Serial Recall and Order Recognition Memory

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Traditional theories posit language comprehension and production aid verbal working memory (VWM) for familiar sequences, but not novel ones.
• Emergent language theories suggest language processes can support VWM even for novel word lists.

Purpose of the Study:

• To investigate whether novel noun sequences resembling natural language patterns enhance VWM.
• To determine if language knowledge influences the recall and order recognition of novel word sequences.

Main Methods:

• Corpus analyses to identify novel two-noun sequences mirroring natural language patterns.
• Three experiments involving college students to assess recall and order recognition of these sequences compared to reversed controls.

Main Results:

• Participants demonstrated significantly better recall for novel noun sequences that approximated natural language patterns compared to their reversed counterparts.
• Improved recognition of the order of these sequences was observed over a longer time scale.
• These findings indicate language knowledge influences memory for novel sequences.

Conclusions:

• Verbal working memory and order recognition are modulated by language knowledge, even for novel stimuli.
• Novel memoranda that approximate natural language patterns are more effectively processed and retained in VWM.
• This supports the role of language processes in supporting memory for novel sequences.
