Summary: Strong adaptive skills in early childhood — including communication, self-care, and social competence — can help shield a child’s developing brain from some of the long-term effects of prenatal stress. Researchers treated Superstorm Sandy as a natural experiment to study mothers who were pregnant during the disaster and followed their children over several years.
The study found that children who developed high adaptive behavior between ages 2 and 6 maintained healthy brain activation in emotional-processing centers at age 8, even when their prenatal environment included significant stress.
Key Facts
- The “Limbic Shield”: fMRI scans at age 8 showed that children with strong early adaptive skills had limbic system activation similar to children not exposed to prenatal stress.
- Resilience in Action: Children who demonstrated lower adaptive skills showed notably reduced activation in brain regions responsible for emotional regulation and sensory processing when their mothers experienced high stress during pregnancy.
- Natural Model: The 2012 Superstorm Sandy cohort provided a clear, time-bound exposure to prenatal stress, allowing researchers to track developmental trajectories across childhood.
- Actionable Interventions: Early childhood programs that build independence and social functioning may not only improve behavior but also support healthy brain responses to stress.

Researchers from the City University of New York (CUNY) Graduate Center and Queens College report that strengthening adaptive skills in early childhood may buffer the developing brain from the harmful effects of prenatal stress.
Adaptive skills are everyday abilities that allow children to function independently and interact effectively with others. These include communication, self-care (such as dressing and hygiene), and social skills like sharing, turn-taking, and responding to peers and adults.
Published in Developmental Neuroscience, the study focused on children whose mothers were pregnant when Superstorm Sandy, a severe post‑tropical cyclone, struck the New York area in October 2012. The storm served as a measurable prenatal stressor with a clearly defined exposure window, allowing investigators to examine how early-life skills influence later brain function.
Behavioral Skills and Brain Development
As part of the Stress in Pregnancy (SIP) Study, researchers conducted yearly behavioral assessments of children between ages 2 and 6. These measures tracked adaptive behaviors—practical skills that support everyday functioning, such as communicating needs, dressing independently, and managing social exchanges.
A subgroup of 34 children later took part in a pilot neuroimaging study at the Advanced Science Research Center at the CUNY Graduate Center. Using functional magnetic resonance imaging (fMRI), investigators measured brain activation while children performed an emotional face processing task that required viewing and matching facial expressions.
The imaging results linked early adaptive skills with how prenatal stress affected activation in limbic regions involved in emotion regulation, sensory processing, and memory. Specifically, children exposed prenatally to the storm who had higher adaptive skills displayed limbic activation patterns comparable to unexposed peers, while those with lower adaptive skills showed blunted activation in key emotional-processing areas.
“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.”
Monika Baldyga, M.A., a researcher at Queens College, added: “The skills children build in everyday life may shape how their brains develop. Seeing that reflected in the imaging data was incredibly meaningful.”
Implications for Interventions
While larger, replicated studies are needed, the findings point to early adaptive skills as potential protective factors against the neural consequences of prenatal stress. As extreme weather events and other stressors associated with climate change become more frequent, more women may face significant stress during pregnancy. Prioritizing interventions that foster communication, self-care, and social competence in young children could therefore support both behavioral and neural resilience.
“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,” said Yoko Nomura, Ph.D., distinguished professor of Psychology at Queens College and the CUNY Graduate Center.
From a neuroimaging perspective, the study highlights the brain’s capacity for resilience. “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,” said A. Duke Shereen, Ph.D., director of the Neuroimaging Core at the CUNY ASRC.
Translating these results into practice will require collaboration between researchers, clinicians, educators, and policymakers to implement programs that protect children’s brain health following prenatal adversity.
Key Questions Answered:
A: Adaptive skills are practical, everyday abilities that allow a child to function independently and engage socially. Examples include communicating needs, basic self-care like dressing and hygiene, and interacting appropriately with peers and adults.
A: The study does not claim these skills reverse all effects of prenatal stress. Instead, it finds that higher adaptive skills appear to buffer or moderate the impact of prenatal stress on limbic brain activation, supporting healthier patterns of neural response during emotional processing.
A: Developing independence and social competence strengthens problem-solving and self-regulation. Those experiences likely reinforce neural pathways that support emotional regulation and stress response, contributing to resilience in brain circuits affected by early adversity.

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 substantial capacity to adapt after early adversity, but it remains unclear which behaviors support neural compensation. Prenatal stress offers a natural model to examine protective factors because it changes neurodevelopment while allowing precise timing of exposure.
This study tested whether early adaptive behaviors — practical skills for daily life such as self-care and communication — buffer against neural consequences of prenatal stress. Natural disasters like Superstorm Sandy provide a distinct exposure that researchers can measure and relate to later outcomes.
Methods: In a pilot quasi-experimental design, researchers compared children with (n = 11) and without (n = 23) prenatal exposure to Superstorm Sandy. They examined how adaptive behavior scores from ages 2–6 moderated the relationship between prenatal stress exposure and brain activation during an emotional processing task at age 8. Adaptive behaviors were measured with the Behavior Assessment System for Children, Second Edition (BASC-2). Functional MRI assessed activation in regions involved in facial emotional processing.
Results: Prenatal stress was associated with trends toward reduced adaptive behaviors over time and lower activation in the right ventral anterior insula. Critically, early adaptive behaviors moderated associations between prenatal stress and later activation in the left amygdala, bilateral hippocampus, ventral anterior insula, and rostral anterior cingulate cortex. Analyses showed prenatal stress linked to significantly reduced activation at low adaptive skill levels, but this effect diminished for children with higher adaptive skills, whose activation resembled unexposed peers.
Conclusion: These preliminary moderation findings suggest that adaptive behaviors may act as a neural buffer against prenatal stress. If replicated in larger samples, early interventions that strengthen adaptive skills could reduce the neural burden of prenatal stress and promote more resilient brain development in at-risk populations.
