Auditory rhythm facilitates perception and action in children at risk for developmental coordination disorder

Area of Science:

• Neuroscience
• Developmental Psychology
• Auditory Perception

Background:

• Developmental Coordination Disorder (DCD) is a common neurodevelopmental disorder affecting motor skills in children.
• Deficits in rhythmic tracking and auditory-motor synchronization are observed in various motor disorders.
• Auditory rhythms are increasingly used in rehabilitation programs for motor impairments.

Purpose of the Study:

• To investigate auditory-motor deficits in children at risk for DCD.
• To determine if auditory rhythmic regularity benefits auditory perception and motor coordination in these children.
• To explore the link between auditory-motor performance and standardized motor assessments.

Main Methods:

• A speech recognition task with rhythmic modulation was administered to children at risk for DCD and typically developing (TD) children.
• Auditory-motor tapping tasks were performed with and without rhythmic cues (metronome, music).
• Standardized motor assessments were used to evaluate motor coordination.

Main Results:

• Children at risk for DCD performed worse on the speech recognition task when speech rhythm was modulated compared to TD children.
• While children at risk for DCD generally showed less consistent tapping, rhythmic cues improved their tapping temporal consistency.
• Accuracy in speech rhythm recognition and tapping consistency correlated with motor assessment performance.

Conclusions:

• Children at risk for DCD exhibit specific auditory-motor deficits.
• Auditory rhythmic regularity enhances both auditory perception and auditory-motor coordination in children with DCD.
• These findings support the development of interventions based on auditory-motor rhythmic coordination for DCD.
