Sound-sized segments are significant for Mandarin speakers.

Area of Science:

• Psycholinguistics
• Cognitive Neuroscience
• Phonology

Background:

• Language production models often assume phonemes as fundamental units.
• Evidence primarily stems from alphabetic European languages.
• Non-alphabetic scripts, like Mandarin Chinese, lack explicit phonemic orthography, questioning universal phoneme use.

Purpose of the Study:

• To investigate the role of phonemes in Mandarin Chinese language production.
• To determine if phonemic segments are fundamental processing units for speakers of languages with non-alphabetic scripts.

Main Methods:

• Utilized event-related potentials (ERPs) and behavioral measurements.
• Mandarin native speakers named object-color phrases.
• Stimuli varied in phonemic overlap between color and object names.

Main Results:

• Behavioral naming latencies were not affected by phoneme repetition.
• Event-related potential (ERP) responses showed modulation around 200 ms post-stimulus onset.
• ERP findings indicate phonemic processing even without orthographic support.

Conclusions:

• Phonemic segments are fundamental units of phonological encoding for Mandarin speakers.
• This supports the universality of phonemic processing in human language production.
• Cognitive processes of speech production may be independent of orthographic systems.
