[Correlation of Phonological STM-Performances with Language-Based Dimensions in Children with APD]

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Speech and Language Therapy

Background:

• Phonological short-term memory (PSTM) is crucial for language processing.
• Auditory processing disorders (APD) can impact language development.
• Understanding the relationship between PSTM and auditory processing is important for intervention.

Purpose of the Study:

• To investigate the association between auditory processing dimensions and PSTM performance.
• To compare these associations in children with and without APD.

Main Methods:

• 178 primary school children (2nd-4th grade) participated.
• 91 children had APD, and 87 were typically developing controls.
• Correlation analyses were used to compare PSTM test performance and verbal-acoustic tasks.

Main Results:

• Children with APD showed significant associations between PSTM measures (e.g., non-word repetition) and verbal-acoustic tasks (e.g., phoneme identification, dichotic word recognition).
• These associations were not found in children without APD.
• PSTM performance was linked to verbal-acoustic task performance specifically in children with APD.

Conclusions:

• The role of PSTM in verbal-acoustic tasks is influenced by auditory processing in children with APD.
• These findings highlight the unique interplay between PSTM and auditory skills in children with APD.
• This suggests targeted interventions may be beneficial for this population.
