Summary: Building strong adaptive skills in early childhood, such as communication and self-care, can shield a child’s brain from the long-term impact of prenatal stress. Researchers used Superstorm Sandy as a “natural experiment” to study mothers who were pregnant during the disaster.
The study found that children who developed high adaptive behavior between ages 2 and 6 maintained healthy brain activity in their emotional-processing centers, even if they were exposed to significant stress in the womb.
Key Facts
- The “Limbic Shield”: Brain scans (fMRI) at age 8 showed that children with strong early-life adaptive skills had limbic system activation comparable to children who weren’t exposed to prenatal stress.
- Resilience in Action: Children with lower adaptive skills showed significantly reduced brain activation in regions responsible for emotional regulation and sensory processing if their mothers faced high stress during pregnancy.
- Natural Model: By studying the 2012 Superstorm Sandy cohort, researchers were able to isolate the effects of environmental stress during pregnancy and track the children’s development over a six-year period.
- Actionable Interventions: The study suggests that early childhood programs focusing on independent functioning and social skills don’t just help behavior—they literally protect the brain’s physical response to stress.

Researchers from the City University of New York (CUNY) Graduate Center and Queens College suggest that building strong adaptive skills in early childhood may serve as a buffer against the detrimental effects of prenatal stress on a child’s developing brain.
Adaptive skills refer to everyday abilities that help children function independently and interact effectively with others, such as communication, social skills, and the ability to manage daily tasks like self-care.
The study, published in Developmental Neuroscience, examined children whose mothers were pregnant during Superstorm Sandy, a powerful and devastating Category 3 hurricane that struck New York City and surrounding areas as a post-tropical cyclone in October 2012.
Researchers used the storm as a natural model of prenatal stress exposure to explore how the development of adaptive skills across early childhood years may help to maintain neural responsiveness in exposed children.
Behavioral Skills and Brain Development
As a part of the Stress in Pregnancy (SIP) Study, mothers and their children completed yearly behavioral visits between ages 2 and 6. These assessments measured children’s adaptive behaviors, everyday developmental skills that help them function independently, including self-care, communication, and social interaction.
Later in childhood, at around age 8, a subgroup of 34 children also participated in a pilot brain imaging study at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC).
Researchers used functional magnetic resonance imaging (fMRI) scans to measure the children’s brain activation while they completed a task that required them to view and select matching emotional facial expressions.
The brain scans revealed that early adaptive skills influenced how prenatal stress later affected brain activation in emotional-processing regions of the limbic system, which is involved in emotional regulation, sensory processing, and memory formation.
“The brain scans showed something striking,” said Donato DeIngeniis, M.A., a Ph.D. candidate in the CUNY Graduate Center’s Psychology program. “Children exposed to prenatal stress but who developed stronger adaptive skills early in childhood showed brain activation patterns comparable to their unexposed peers. This suggests that what happens in those early developmental years really matters for how the brain responds later.”
Children with lower adaptive skills in early childhood showed significantly reduced limbic brain activation if they were exposed to prenatal stress. However, children with stronger adaptive skills showed brain activation patterns like those of children not exposed to prenatal stress, which suggests that these everyday skills may help protect brain function.
“This research grew out of my master’s thesis, and what drew me to this question was the idea that children are not passive recipients of early adversity,” said Monika Baldyga, M.A., a researcher at Queens College. “The skills they build in everyday life may shape how their brains develop. Seeing that reflected in the imaging data was incredibly meaningful.”
Implications for Interventions
Although replicated studies with larger samples are needed, the current findings suggest that building adaptive skills in early childhood may serve as a safeguard against the harmful effects of exposure to stress during pregnancy.
“As natural disasters intensify with climate change, more women will face significant stress during pregnancy,” said the study’s principal investigator Yoko Nomura, Ph.D., distinguished professor of Psychology at Queens College and the CUNY Graduate Center.
“These findings give us reason to focus early intervention efforts on building adaptive skills in young children, not just for their behavioral development, but as a potential safeguard for their brain health.”
“From a neuroimaging standpoint, these findings highlight the brain’s remarkable capacity for resilience,” said Duke Shereen, Ph.D., director of Neuroimaging Core at the CUNY ASRC.
“Even after exposure to significant prenatal stress, children who built strong adaptive skills maintained healthy patterns of limbic activation, which are the very circuits that regulate emotion and stress response.”
Translating these findings into practice will require collaboration among research scientists, clinicians, and policymakers to implement strategies that protect children’s brain health and mental well-being following prenatal adversity.
Key Questions Answered:
A: These are the practical, everyday skills that help a child function independently. Examples include communicating their needs, managing basic self-care (like getting dressed), and knowing how to interact socially with peers and adults.
A: While the study doesn’t claim to “fix” damage, it shows that these skills act as a biological buffer. They help maintain healthy patterns in the limbic system, essentially allowing the brain to bypass the typical “blunting” effect that prenatal stress can have on emotional circuits.
A: It’s about the brain’s capacity for resilience. Building independent skills reinforces neural pathways involved in problem-solving and self-regulation. When a child feels capable and interacts effectively with their world, it appears to support the healthy development of the circuits that regulate their stress response.

Abstract
Adaptive Skills May Moderate the Association Between Prenatal Stress Exposure and Limbic Brain Activation: A Developmental fMRI Study of Superstorm Sandy Exposure
Introduction: The developing brain shows remarkable capacity for adaptation following early adversity, but the behaviors that influence neural compensation mechanisms remain unclear. Prenatal stress exposure provides a natural model for studying these mechanisms, as it alters neurodevelopment while allowing examination of potential protective factors.
However, whether early adaptive behaviors – the skills needed to meet everyday demands such as self-care and communication – can buffer against the neural consequences of prenatal stress has not been established. Natural disasters provide a unique opportunity to examine these mechanisms, as they serve as measurable prenatal stressors with well-defined exposure timing.
Methods: In this pilot study, using a quasi-experimental design, we examined children with (n = 11) and without (n = 23) prenatal exposure to Superstorm Sandy (SS) to investigate how early adaptive behavior (aged 2–6 years) moderates the association between prenatal stress (i.e., exposure to a natural disaster) and later brain activity during emotional processing (age 8 years).
We first examined main effects of SS on both adaptive behaviors over time (aged 2–6 years) and functional brain activation at age 8 years in brain regions responsible for facial emotional processing.
Moderation models subsequently explored whether early-life adaptive behaviors influenced the association between SS and later brain activation. The Behavior Assessment System for Children, Second Edition (BASC-2) measured child adaptive behaviors. Functional magnetic resonance imaging (fMRI) measured regional brain activation using an emotional face processing task.
Results: Prenatal stress exposure was associated with nonsignificant trends toward reduced adaptive behaviors over time and reduced brain activation in the right ventral anterior insula. Critically, early adaptive behaviors moderated the association between prenatal stress and later brain activation in the left amygdala and both hemispheres of the hippocampus, ventral anterior insula, and rostral anterior cingulate cortex.
Simple slope analyses revealed that prenatal stress was associated with significantly reduced brain activation at low adaptive skills. However, this association was attenuated among children that exhibited higher adaptive skills such that activation patterns were comparable to their unexposed peers.
Conclusion: Our preliminary moderation (i.e., interaction) findings provide initial evidence that adaptive behaviors may serve as a neural buffer against prenatal stress. This protective pattern indicates that early adaptive skills may help maintain neural responsiveness following prenatal stress exposure.
If validated in larger, adequately powered samples, interventions targeting adaptive behaviors in early childhood could potentially reduce the neural burden of prenatal stress and support more resilient brain development in at-risk populations. These findings highlight adaptive behaviors as potential targets for early intervention to promote neural resilience following prenatal adversity.
