Insights
Infants' negative emotionality influences how parent-child relationships affect self-regulation. Highly negative infants thrive in responsive relationships, while others show no effect, supporting the differential susceptibility model.
Area of Science:
- Developmental Psychology
- Child Psychology
- Behavioral Science
Background:
- Parent-child relationships significantly impact child development.
- Mutually responsive orientation (MRO) is a key aspect of positive parent-child interactions.
- Infants' individual differences, such as negative emotionality, may moderate these effects.
Purpose of the Study:
- To investigate if infants' negative emotionality moderates the association between parent-child MRO and children's self-regulation.
- To differentiate between the diathesis-stress and differential susceptibility models in this context.
Main Methods:
- Longitudinal study of 102 infants.
- Negative emotionality assessed at 7 months.
- MRO coded at 15 months.
- Self-regulation measured at 25 months using effortful control tasks and compliance.
Main Results:
- Negative emotionality moderated the mother-child MRO-self-regulation link.
- Highly negative infants showed better self-regulation with high MRO and poorer with low MRO.
- Infants low in negative emotionality did not show a link between MRO and self-regulation.
- No moderation effect was found for father-child MRO.
Conclusions:
- Infants' negative emotionality is a crucial factor in understanding the impact of MRO on self-regulation.
- Findings support the differential susceptibility model, indicating sensitive periods where environmental influences are amplified by individual traits.
- The findings highlight the importance of sensitive parenting for infants prone to negative emotionality.
Abstract:
This study examined infants' negative emotionality as moderating the effect of parent-child mutually responsive orientation (MRO) on children's self-regulation (n=102). Negative emotionality was observed in anger-eliciting episodes and in interactions with parents at 7 months. MRO was coded in naturalistic interactions at 15 months. Self-regulation was measured at 25 months in effortful control battery and as self-regulated compliance to parental requests and prohibitions. Negative emotionality moderated the effects of mother-child, but not father-child, MRO. Highly negative infants were less self-regulated when they were in unresponsive relationships (low MRO), but more self-regulated when in responsive relationships (high MRO). For infants not prone to negative emotionality, there was no link between MRO and self-regulation. The "regions of significance" analysis supported the differential susceptibility model not the diathesis-stress model.

Parenting Styles
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
