Children with ASD establish joint attention during free-flowing toy play without face looks

Area of Science:

• Developmental Psychology
• Neurodevelopmental Disorders
• Cognitive Science

Background:

• Joint attention (JA) is crucial for learning and language acquisition in children.
• Traditional views of JA in autism spectrum disorder (ASD) focus narrowly on gaze and pointing.
• Emerging evidence suggests JA can be achieved through multiple pathways beyond direct gaze.

Purpose of the Study:

• To investigate the pathways and characteristics of joint attention (JA) episodes during naturalistic parent-child play.
• To compare JA in children with ASD to typically developing (TD) children using dual eye-tracking.
• To explore how JA influences parent's object naming during play.

Main Methods:

• Utilized dual head-mounted eye tracking to objectively record gaze patterns during free-play interactions.
• Defined joint attention (JA) as simultaneous shared gaze on the same object by parent and child.
• Analyzed gaze behaviors and parent's object naming frequency for jointly attended versus non-jointly attended objects.

Main Results:

• Both ASD and TD children rarely looked at their parent's face during unstructured play.
• Both groups demonstrated high, non-chance rates of joint attention (JA), indicating the use of alternative pathways.
• Alternative JA pathways were similarly utilized across both groups, leading to increased object naming by parents.

Conclusions:

• Joint attention (JA) in children with ASD can be achieved through diverse pathways beyond face-gaze.
• Findings challenge narrow operationalizations of JA impairment in ASD, suggesting broader capabilities.
• The study highlights the importance of considering multiple communicative cues in understanding JA and its role in development.
