Insights
Early social impairment affects infant responses to distress. Familiarity also plays a role, with infants showing more attention to unfamiliar people and more emotion toward familiar ones.
Area of Science:
- Developmental Psychology
- Social Neuroscience
- Autism Spectrum Disorder (ASD) Research
Background:
- Early social-emotional development is crucial for later functioning.
- Impaired responses to distress can signal social difficulties.
- Understanding factors influencing these responses can aid early intervention for conditions like ASD.
Purpose of the Study:
- To investigate the relationship between social impairment and infant responses to partner distress.
- To examine the influence of partner familiarity on infant distress responses.
- To identify key factors affecting early social engagement with distressed partners.
Main Methods:
- Assessed infants (12 and 15 months) with and without older siblings with ASD.
- Measured social impairment markers and infant responses to simulated maternal and experimenter distress.
- Analyzed attention and affective responses in relation to social impairment and familiarity.
Main Results:
- Greater social impairment correlated with reduced attention and affect at 15 months, but not 12 months.
- Infants showed increased attention toward unfamiliar experimenters versus mothers.
- Infants displayed greater affective responses toward familiar mothers compared to unfamiliar experimenters at 12 months.
Conclusions:
- Social impairment and partner familiarity independently influence infant responses to distress.
- These findings highlight the complex interplay of individual differences and relational context in early social-emotional development.
- Results may inform targeted assessments and interventions for infants at risk for social developmental challenges.
Abstract:
Early impaired response to social partners' distress may negatively impact subsequent social development. Identifying factors contributing to successful responding may inform assessment and intervention. This study explores how: (1) social impairment, and (2) partner familiarity relate to response to partners' distress. Infants with and without older siblings with ASD were assessed at 12 (n = 29) and 15 (n = 35) months for social impairment markers, and responses to mother and experimenter each feigning distress. Infants with more social impairment showed less attention and affect at 15, but not 12 months. Infants attended more to the unfamiliar person, but exhibited greater affect toward the familiar person at 12 months. Results revealed social impairment and familiarity were separately related to infant response to partners' distress.
