Researchers from Frontiers in Child and Adolescent Psychiatry studied 124 parent-child pairs to understand how a child's emotional sensitivity and a parent's stress responses interact to shape aggressive behaviour. The question they asked: does a parent's own emotional reactivity influence how their child behaves, particularly around aggression?
The findings reveal that aggression isn't simply about the child's temperament alone. Instead, it emerges from a combination of your child's nervous system and your own emotional responses.
Children who seem unaffected by others' feelings are at highest risk
Children who display callous or unemotional traits—appearing indifferent to others' distress—showed higher rates of both impulsive and planned aggression. Interestingly, this risk increased further when paired with a parent who is highly sensitive to emotional cues. The mismatch between parent sensitivity and child indifference appears to amplify aggressive tendencies.
A fearless child's aggression looks different from a reactive child's
Children with low fear responses tend toward reactive aggression—the impulsive, in-the-moment outbursts during conflicts. This is the child who lashes out without thinking. The study distinguishes this from planned, calculated aggression, which emerges through a different pathway involving how both parent and child process threats.
Your own emotional reactions set the tone for planned aggression
Here's the striking finding: if your child has a strong physiological response to threat but you remain emotionally unmoved when others are distressed, your child is actually less likely to develop planned aggression. However, when both you and your child are highly reactive to emotional stimuli, the risk of calculated aggression increases significantly. Your emotional response doesn't just influence your child's immediate behaviour—it shapes their capacity for deliberate, strategic aggression.
In Singapore's high-pressure environment, where both parents and children experience considerable stress, this matters. The study shows that completely suppressing emotion isn't the answer, despite cultural values around composure. There's a middle ground: acknowledging what you feel while responding in regulated ways. Additionally, this research confirms what many parents sense: children have different nervous systems. One child may need calm reassurance; another needs a parent who stays emotionally steady. Generic advice won't work for every child.
Three steps based on this research
- Notice your own stress response before reacting to your child's behaviour—pause and check whether you're emotionally escalating.
- If your child seems indifferent to others' feelings, be intentional about modelling empathy rather than assuming they'll naturally develop it.
- Recognise whether your child is prone to reactive or planned aggression and adjust your response style accordingly, rather than applying the same strategy to all situations.
