Brain scans reveal developmental shifts in phonological processing. As children age, their brains rely less on auditory memory and more on articulation for word tasks, showing changes in brain region connectivity.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Cognitive Science

Background:

  • Phonological processing is crucial for reading development.
  • Understanding how brain networks supporting phonological tasks mature is key to explaining reading acquisition.
  • Previous research suggests age-related changes in brain activation during language tasks.

Purpose of the Study:

  • To investigate developmental changes in brain activation and effective connectivity during a phonological processing task.
  • To examine how functional brain networks reorganize during childhood and adolescence for word-based tasks.
  • To differentiate between changes in regional activation and network interactions during cognitive maturation.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was used to scan participants aged 9-15.

  • Participants performed a rhyming judgment task on visually presented word pairs.
  • Orthographic and phonological similarity were independently manipulated to isolate phonological processing.

    • Main Results:

    • Increased activation in the dorsal left inferior frontal gyrus (IFG) and decreased activation in the dorsal left superior temporal gyrus (STG) with age.
    • Increased functional coupling of the dorsal IFG with other brain regions involved in phonological decisions.
    • Decreased functional coupling of the STG with age, and increased activation in the left posterior parietal cortex without altered connectivity.

    Conclusions:

    • Developmental changes in phonological processing involve a shift from sensory-based to articulation-based strategies.
    • Brain maturation includes both changes in regional activity and the strengthening or weakening of network connections.
    • Maturation of cognitive functions may involve increased efficiency within regions rather than solely increased inter-regional communication.
