Long-term phonological knowledge supports serial ordering in working memory.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Speech Science

Background:

• Serial ordering mechanisms are crucial for memory and language processing.
• Long-term phonological knowledge significantly impacts serial recall.
• The precise mechanisms underlying serial ordering require further elucidation.

Purpose of the Study:

• To investigate the underlying mechanisms of serial ordering in immediate serial recall.
• To demonstrate novel bielement frequency and position-element frequency effects in Japanese nonwords.
• To provide evidence for minicontext representations and long-term associations between positional and element information.

Main Methods:

• Utilized immediate serial recall tasks with Japanese nonwords.
• Analyzed bielement frequency effects, including retrograde compatibility.
• Examined position-element frequency effects to understand positional influences on recall.

Main Results:

• Demonstrated that bielement frequency affects recall for both preceding and succeeding elements, suggesting minicontext representations.
• Showed that elements appearing frequently in specific positions are recalled better, indicating position-element associations.
• Provided empirical support for the extensive learning hypothesis regarding phonological structure acquisition.

Conclusions:

• Serial ordering relies on learned associations between elements and their positions.
• Minicontext representations of frequent sequences play a role in memory.
• Findings have implications for understanding gradual phonological learning and computational modeling.
