Summary: New research indicates that adult risk-taking behavior may be shaped more by the types of resources available during childhood than by an inherent tendency toward risk. In a study using fMRI, people who grew up with strong social support but limited economic means (“socially rich”) and those who grew up with greater economic resources but less social support (“economically rich”) showed similar risk-taking behavior but relied on different neural systems to arrive at those decisions.
Functional brain scans showed that socially rich individuals engaged visual and attention-related brain regions more strongly during risky choices, and that current levels of social support changed how much additional neural effort these individuals needed. The results suggest that distinct childhood socioeconomic experiences can calibrate the brain’s strategies for decision-making, producing similar outcomes through different neural pathways.
Key Facts
- Different resources, similar choices: Participants characterized as socially rich and economically rich took comparable risks but activated different brain circuits.
- Current social support matters: Among socially rich participants, greater present-day social support reduced extra brain activation and related to higher risk-taking and earnings in the task.
- Neural “brake” on risk: Activation in the supramarginal gyrus was associated with more cautious choices across the sample, pointing to a neural mechanism that limits risky behavior.

How risk-averse are you?
Researchers in Cornell’s College of Human Ecology explored whether adult risk preferences reflect how people adapted cognitively and neurologically to the resource environment they experienced growing up. Instead of grouping all forms of adversity together, the team separated social and economic resources to examine their distinct developmental impacts.
Their findings show that people who had relatively stronger social networks but fewer economic resources in childhood and those with the opposite profile behave similarly on a laboratory risk task, yet they recruit different brain regions when making those choices. This suggests early-life resource asymmetry—differences in social versus economic access—shapes the neurocognitive strategies individuals use in adulthood.
The study, published July 4 in Cerebral Cortex, was led by Minwoo Lee, a postdoctoral researcher in the College of Human Ecology and member of the Life History Lab headed by Marlen Z. Gonzalez, an assistant professor of psychology and co-author on the paper.
“Distinct early-life environments may give rise to different resources and strategies for solving common life problems,” Lee said. “Over time, these experiences can shape the cognitive mechanisms and contextual cues people rely on as adults.”
Gonzalez added, “It’s important to consider multiple resource types—social and economic—because both can be used to manage stress and adversity.”
To probe these developmental effects, researchers recruited 43 Cornell students whose backgrounds varied in childhood economic standing and perceived neighborhood quality, alongside current measures of economic status and recent social support. The student sample was seen as a strength because it includes individuals with diverse developmental histories who now share the same campus environment, allowing researchers to examine how prior calibration plays out in a common setting.
During fMRI scanning, participants played a computerized balloon analog risk task. They made repeated choices to pump virtual balloons to earn small monetary rewards per pump, with the option to cash out at any time. Some balloons could explode at random and forfeit earnings, others offered guaranteed rewards, and a neutral type produced no gain or loss. The team focused on neural activity tied to decisions to press the “pump” button despite potential loss.
Survey data on family income during childhood, neighborhood safety and quality, current economic standing, and recent social support were used to classify participants as socially rich or economically rich. Though both groups showed similar average levels of risk-taking, imaging revealed two important neural distinctions.
First, increased activity in the supramarginal gyrus correlated with more cautious behavior across participants, identifying it as a possible neural brake on risk. Second, socially rich participants selectively recruited occipito-parietal regions involved in visual and attentional processing when taking risks. Crucially, higher current social support reduced this extra recruitment: socially rich individuals with stronger present-day networks required less additional neural effort, took more risks, and earned more in the task than those with weaker current support.
“There appears to be a shared mechanism that enables risk-taking across groups,” Lee said. “But the route to that behavior differs. Individuals arrive at similar choices using different neural and contextual strategies shaped by their developmental histories.”
These insights into how childhood social and economic experiences calibrate adult decision-making have practical implications. Tailored supports—through public policy, community investments, or campus services—could help level the playing field. For example, universities might identify students who were socially rich but lack support on campus and focus on strengthening their social networks so they don’t have to expend extra effort to achieve the same outcomes.

“Asymmetric access to social vs. economic resources during development calibrates socio-cognitive pathways to risk-taking in emerging adults” by Minwoo Lee et al. Cerebral Cortex
Abstract
Asymmetric access to social vs. economic resources during development calibrates socio-cognitive pathways to risk-taking in emerging adults
Developmental plasticity allows organisms to adapt to early-life conditions by tuning neurocognitive and behavioral strategies to local risks and available resources. Much prior work treats childhood adversity as a single aggregate, leaving the distinct impact of social versus economic environments on adult brain function and behavior understudied.
This study examined how different childhood socioeconomic contexts—relative access to social or economic resources—shape adult risk-taking and its neural underpinnings. Participants completed a balloon analog risk task during functional MRI, and researchers used computational models to estimate risk-taking tendencies in relation to both developmental and current socioeconomic factors.
Although the groups displayed similar average risk tendencies, socially rich participants showed a negative relationship between current social support and risk-taking. Across participants, risk-taking engaged the supramarginal gyrus. Uniquely, socially rich individuals recruited occipito-parietal cortices during risky decisions, a pattern reduced by higher current social support. Additionally, connectivity between the supramarginal gyrus and prefrontal cortex tracked mismatches between childhood and present resources, suggesting a “sensitized-specialization” of neural networks.
These findings demonstrate that exposure to distinct early-life resource environments produces divergent neural strategies for similar adult behaviors, with implications for designing interventions that consider individuals’ developmental histories.
