Universal Restrictions in Reading: What Do French Beginning Readers (Mis)perceive?

Area of Science:

• Psycholinguistics
• Developmental Psychology
• Phonology

Background:

• Statistical properties are traditionally considered crucial for children's visual identification and syllable segmentation.
• Recent research suggests children may not solely rely on statistical information for locating syllable boundaries.
• Phonological sonority, a universal linguistic feature, is proposed as a potential reliable cue for syllable segmentation.

Purpose of the Study:

• To investigate children's sensitivity to the universal phonological sonority-based markedness continuum for syllable segmentation.
• To examine how this sensitivity evolves with reading acquisition in typically developing children.
• To determine if phonological sonority influences syllable segmentation independently of statistical information.

Main Methods:

• A longitudinal study using the illusory conjunction (IC) paradigm with 48 French typically developing children.
• Children were tested at three time points over one year.
• Participants included "good" and "poor" readers, with chronological ages around 81 months at baseline.

Main Results:

• Syllable segmentation abilities were confirmed to develop with reading experience and proficiency.
• A significant Condition × Sonority interaction demonstrated that phonological sonority modulates syllable segmentation.
• This sensitivity to sonority for syllable segmentation is present early and is independent of reading level and statistical cues.

Conclusions:

• Children's syllable segmentation is influenced by phonological sonority, particularly at syllable boundaries.
• This sensitivity emerges early and is not dependent on reading level, suggesting a fundamental phonological processing mechanism.
• Phonological sonority plays a role in syllable segmentation even with minimal statistical information, challenging purely statistical models.
