Reduced Face Preference in Infancy: A Developmental Precursor to Callous-Unemotional Traits?

Area of Science:

• Developmental Psychology
• Child Psychiatry
• Neuroscience

Background:

• Callous-unemotional (CU) traits in children may precede adult psychopathy.
• These traits include impaired emotion recognition and lack of empathy.
• Reduced attention to faces, particularly eye regions, is a hypothesized cause, but not previously studied longitudinally from infancy.

Purpose of the Study:

• To investigate if infants' preferential face tracking and maternal sensitivity predict later CU traits.
• To examine early developmental markers for children at risk for CU traits.

Main Methods:

• Longitudinal study of 213 infants and their mothers from a population-based sample.
• Infant face tracking assessed at 5 weeks; maternal sensitivity at 29 weeks.
• CU traits assessed at 2.5 years using weighted linear regression.

Main Results:

• Lower preferential face tracking in infancy predicted higher CU traits (p = .001).
• Higher maternal sensitivity predicted lower CU traits in girls (p = .009), but not boys.
• No significant interaction found between face tracking and maternal sensitivity.

Conclusions:

• This is the first study demonstrating that infant attention to social cues and sensitive parenting predict subsequent CU trait development.
• Early identification of atypical development in face attention and parenting offers potential for parent-mediated interventions in at-risk children.
