Summary

Right hemisphere damage in children can cause aprosodia, affecting emotional language expression. This study introduces "children aprosodia" for acquired affective-prosodic deficits in pediatric right brain injury.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Linguistics

Background:

  • The right hemisphere is dominant for affective language processing in adults, including prosody and gesturing.
  • Deficits in affective processing due to right brain damage are termed aprosodias, analogous to aphasias from left brain damage.
  • Developmental affective-prosodic deficits have been noted in children with early right hemisphere injury.

Observation:

  • This study reports on two school-aged children with acquired motor-type aprosodias following acute focal right brain injury.
  • Acoustic analysis of affective prosody and singing was performed during acute and recovery phases.

Findings:

  • The two children presented with acquired motor-type aprosodias, indicating a deficit in expressing emotion through speech.
  • Analysis revealed specific acoustic patterns related to their affective prosody and singing abilities.

Implications:

  • The findings support the role of the right hemisphere in affective language development in children.
  • The term "children aprosodia" is proposed to describe these specific acquired deficits.
  • This research highlights the need for recognizing and addressing affective-prosodic deficits in pediatric acquired brain injury.
