[Exploring joint attention processes in young children with autism spectrum disorder]

Area of Science:

• Developmental Psychology
• Neurodevelopmental Disorders
• Clinical Psychology

Background:

• Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by early-onset symptoms, including communication impairments.
• Joint attention, the ability to share attention, is a key social communicative skill often impaired in ASD.
• Early identification of factors influencing joint attention in infants is crucial for timely intervention.

Purpose of the Study:

• To investigate the role of visual regulation, attentional engagement, and social motivation in joint attention in young children with ASD.
• To examine the mediating role of motivation in the relationship between visual regulation and joint attention.
• To develop and validate a clinical measure for motivation behaviors in children with ASD.

Main Methods:

• A cohort of 50 children with ASD (21-50 months) underwent clinical assessments.
• Evaluations included developmental and symptom assessments, auditory/visual regulation scales, and motivation behavior quantification.
• Joint attention was measured using the Early Communication Scale for Children (ECSC), and attentional disengagement was assessed.

Main Results:

• Visual regulation demonstrated a significant effect on joint attention.
• Motivation partially mediated the relationship between visual regulation and joint attention.
• Attentional disengagement was also found to be associated with joint attention.

Conclusions:

• A mediation model highlights motivation's influence on the mechanisms underlying joint attention in ASD.
• Early measurement of motivation and attentional disengagement can inform intervention strategies.
• The developed clinical measure for motivation behaviors is applicable in clinical settings for ASD diagnosis and intervention.
