Object Exploration and Manipulation in Infants at Typical vs. Elevated Likelihood for ASD: A Review

Area of Science:

• Neurodevelopmental disorders
• Pediatric motor development
• Autism Spectrum Disorder (ASD) research

Background:

• Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition.
• Early identification of ASD is crucial for timely intervention.
• Fine motor skills in infancy are emerging as potential early markers for ASD risk.

Purpose of the Study:

• To review the literature on fine motor skills in infants with elevated genetic likelihood (EL) for ASD.
• To identify potential motor markers for earlier and more accurate ASD identification.
• To discuss the predictive value of infant fine motor skills for later ASD diagnosis.

Main Methods:

• Review of existing scientific literature on fine motor skills in EL infants.
• Analysis of studies using standardized assessments, observational measures, and technological tools.
• Examination of developmental trajectories and exploratory behaviors in EL infants.

Main Results:

• Infants with EL for ASD exhibit distinct developmental trajectories in fine motor skills compared to typically developing infants.
• Differences in fine motor skills and exploratory behaviors are observed in EL infants.
• Fine motor skill development in infancy shows potential as an early indicator of ASD risk.

Conclusions:

• Fine motor skills represent a significant area for early ASD risk identification in infants.
• Further research is needed to fully understand the predictive value and underlying mechanisms of these motor markers.
• Identifying early motor markers can facilitate earlier diagnosis and intervention for ASD.
