Perception-action coupling and imitation in autism spectrum disorder

Area of Science:

• Developmental Psychology
• Neuroscience
• Pediatrics

Background:

• Imitation plays a vital role in motor and social development.
• It is fundamental for typically developing infants and children with autism spectrum disorder (ASD).
• Imitation's capacity for plasticity and growth supports its role as a developmental cornerstone.

Purpose of the Study:

• To highlight the significance of imitation in infant development.
• To explore imitation's role in children with autism spectrum disorder (ASD).
• To propose imitation as a potential cornerstone for various neurodevelopmental disorders.

Main Methods:

• Review of existing literature on imitation and developmental psychology.
• Analysis of the mechanisms underlying imitation, including motor pattern matching.
• Examination of imitation's role in learning and communication.

Main Results:

• Imitation requires matching perceived motor patterns to one's own repertoire.
• Newborns can imitate actions within their motor scope, demonstrating early imitation abilities.
• Imitation is a 'use it or lose it' skill, enhancing plasticity and repertoire growth.

Conclusions:

• Imitation is essential for both learning and communication, with two facets: imitating and being imitated.
• Interactive imitation involves coordinated bottom-up and top-down processes, as shown in neuroimaging studies.
• Imitation serves as a developmental booster, beneficial for children with neurodevelopmental disorders, including ASD.
