Children's knowledge of auditory/articulatory correspondences: phonologic and metaphonologic

Area of Science:

• Child language acquisition
• Speech-language pathology
• Developmental psychology

Background:

• Understanding how children learn speech sound rules is crucial for identifying developmental delays.
• Metaphonologic knowledge, specifically auditory/articulatory correspondences, plays a role in speech development.

Purpose of the Study:

• To investigate the development of metaphonologic knowledge in normally developing children aged 5, 6, and 7.
• To examine the relationship between nonverbal and verbal assessments of auditory/articulatory correspondences.
• To explore the connection between metaphonologic skills and phoneme production accuracy.

Main Methods:

• A study involving 45 normally developing children (15 each at mean ages 5, 6, and 7).
• Participants completed nonverbal tasks (identifying correspondences via video screen) and verbal tasks (explaining cues).
• Phoneme production skills were also assessed.

Main Results:

• Significant developmental increases in correct responses on the nonverbal task were observed.
• Changes in the types of verbal explanations correlated with age.
• No significant link was found between metaphonologic task performance and phoneme production skill.

Conclusions:

• Metaphonologic knowledge of auditory/articulatory correspondences develops significantly between ages 5 and 7.
• Verbal explanations of these correspondences also evolve with age.
• Early metaphonologic awareness may not directly predict phoneme production accuracy in typically developing children.
