Flexible parenting rewires mental brains in sensitive infants

Summary: Around 1 in 5 babies are born with a sensitive, unregulated temperament that may raise their risk for anxiety and emotional challenges. A new study shows that contingent responsive parenting—caregivers who accurately respond to a baby’s cues—can reshape early brain activity in ways that support emotional regulation.

Infants who received this kind of caregiving showed calmer reactions to fear and more empathy, while those who didn’t showed brain patterns linked to emotional difficulties. The findings suggest that early, attuned parenting can be a powerful protective factor, especially for high-reactivity babies.

Key Facts:

  • Temperament Risk: 20% of infants have a temperament linked to later emotional challenges.
  • Brain Change: Responsive parenting reshapes infants’ brain activity to support regulation.
  • Behavioral Outcome: These babies show calmer reactions and early signs of empathy.

Approximately 20% of babies are born with a turbulent and unregulated temperament, characterized by high sensitivity to new stimuli, a tendency to cry excessively, and difficulty calming down once emotionally aroused.

Previous studies have identified this temperament as a potential risk factor for challenges in social-emotional development, particularly for the emergence of anxiety disorders.

The current study found that contingent responsive parenting — that is, consistently and accurately responding to the baby’s cues and rhythms — can shape patterns of brain activity in ways that strengthen the child’s capacity for emotional regulation and reduce the likelihood of developing emotional difficulties later in life.

In the study, the researchers followed 51 mother-infant pairs over the course of the babies’ first year.

At four months of age, observations were conducted to assess the infants’ temperament and to evaluate the degree of contingent responsiveness in the mothers’ interactions —how accurately and sensitively they responded to their babies’ cues.

At one year of age, the researchers measured the infants’ brain activity using EEG and examined their reactions to fear and to witnessing others in pain.

The findings show that early parenting influences the baby’s brain activity, which in turn supports their emotional and social behavior. 

Infants with turbulent temperaments who did not experience parental contingent responsiveness developed a pattern of brain activity associated with emotional regulation difficulties, and showed heightened fear in unfamiliar situations and less prosocial behavior.

In contrast, babies with similar temperaments who received contingent responsive parenting did not develop the brain activity associated with emotional difficulties.

Instead, their brain activity supported more adaptive behavior: they responded more calmly to fearful situations and even demonstrated the beginnings of empathy and prosocial behavior in response to the pain of others.

Dr. Tahli Frenkel, Baruch Ivcher School of Psychology, Reichman University: “These findings highlight the critical role of early parenting as a protective factor, especially for infants with more reactive or sensitive temperaments. Such temperaments can be very difficult for both the baby and the parents.

“The study’s findings are encouraging, as they indicate that challenging temperaments can be shaped with the help of an responsive caregiving environment. Babies with more intense temperaments need an environment that helps them regulate their emotions.

“When parents are attuned to the baby’s rhythm, and especially to signals indicating whether the baby is ready to tolerate new stimuli from the environment, they support the development of emotional regulation and build resilience that will help the child cope with the challenges posed by his or her innate temperament.

“Raising awareness among parents, offering them emotional support, and providing them with the knowledge and tools to deal with the natural challenges involved in parenting a baby with a turbulent temperament can have significant and long-term effects on the parenting experience, on the child, and on the parent-child relationship.”

The study, published in the prestigious journal Developmental Psychology as part of a special issue in memory of Jerome Kagan, a pioneer in the study of infant temperament, reinforces the importance of early emotional connections in shaping a healthy developmental trajectory.

Greater awareness, early detection, and tailored interventions have the potential to make a significant and lasting impact on children’s lives.

Maternal Contingent Responsiveness Moderates Temperamental Risk to Support Adaptive Infant Brain and Socioemotional Development Across the First Year of Life” by Tahli Frenkel et al. Developmental Psychology


Abstract

Maternal Contingent Responsiveness Moderates Temperamental Risk to Support Adaptive Infant Brain and Socioemotional Development Across the First Year of Life

In the first few months of life, infants display intriguing individual differences in how they react to novel stimuli in their environment. Infant “negative reactive” tendencies have been robustly linked to resting brain activity profiles that confer risk for maladaptive socioemotional outcomes.

The present study examines whether and how caregiver behavior in early infancy may interact with infant negative reactivity to alter the extent to which such tendencies predict risk-related brain activity profiles.

In the present study, 51 mothers (all White; age M = 32 years, SD = 3; 70.8% monthly household income > 3,400 U.S. dollars) and their infants (39.2% female at birth) participated.

We measured infant negative reactivity and maternal contingent responsiveness to infant’s gaze during mother–infant interactions at age 4 months.

At 10–11 months, we assessed infants’ resting electroencephalographic (EEG) 6–9 Hz frontal asymmetry (a marker of risk for maladaptive regulatory behaviors and withdrawal), infant fearful withdrawal, and infant empathic behavior.

We found that maternal contingent responsiveness to 4-month-old infant’s gaze in naturalistic interactions moderated the relation between 4-month infant negative reactivity and 11-month resting EEG asymmetry.

Results suggest that maternal contingent responsiveness alters the extent to which early reactive tendencies end up “embedded” in infant brain activity profiles.

Exploratory analyses revealed that the interaction between maternal contingent responsiveness and infant reactivity predicting infant resting EEG asymmetry, in turn predicted infants’ fearful withdrawal and empathic behaviors also assessed at 10–11 months.

Findings demonstrate the critical buffering role of maternal contingent responsive behaviors in reducing potential maladaptive neural and socioemotional outcomes.
