INFANT AVOIDANCE DURING A TACTILE TASK PREDICTS AUTISM SPECTRUM BEHAVIORS IN TODDLERHOOD

Area of Science:

• Developmental Psychology
• Neurodevelopmental Disorders
• Infant Behavior

Background:

• Tactile experiences are vital for infant social interaction and development.
• Aversion to touch in infants can indicate potential developmental and behavioral challenges.
• Early identification of risks for atypical development is crucial.

Purpose of the Study:

• To investigate the predictive relationship between infant responses to tactile stimuli and later autism spectrum behaviors.
• To differentiate the predictive power of infant avoidance versus negative affect to touch.
• To explore associations with internalizing and externalizing behaviors in toddlers.

Main Methods:

• Observed 561 nine-month-old infants' avoidance and negative affect during a parent-led tactile task.
• Parents completed the Child Behavior Checklist (PDP, Internalizing, Externalizing scales) when infants were 18 months old.
• Statistical analyses examined the predictive links between infant tactile responses and toddler behaviors.

Main Results:

• Infant avoidance and negative affect during the tactile task were correlated.
• Infant avoidance significantly predicted subsequent Pervasive Developmental Problems (PDP) scores.
• Negative affect did not predict any measured toddler behaviors (PDP, internalizing, or externalizing).

Conclusions:

• Infant tactile avoidance is a potential early indicator for autism spectrum behaviors.
• Measuring responses to touch offers a valuable construct for identifying infants at risk for social impairments.
• Negative affect during tactile tasks may not be a specific predictor of later behavioral issues.
