From remembering to turn off a light to purchasing an electric car, psychology researchers are examining individuals’ proenvironmental behaviors to gain insight into how people become environmentally responsible citizens.
Building on previous work, researchers Gary W. Evans and Siegmar Otto of Cornell University, and Florian G. Kaiser of Otto von Guericke University, Magdeburg wanted to explore the early contributors that have a lasting influence on proenvironmental behavior into young adulthood.
“Given the central contributions of human decision making and behavior to local, regional, and global environmental challenges,” the researchers explain, “better insight into the early origins of adult environmental behavior is fundamental to understanding and ultimately changing environmentally destructive human activity.”
People who hold progressive political values and attain higher levels of education tend to be more inclined toward proenvironmental behavior. Previous research has also shown that parents’ eco-friendly behaviors, especially easily observable ones such as recycling, have an impact on the environmentally responsible behavior of their children. But what kind of effects do these early experiences have on children’s behaviors and attitudes as they age into adulthood?
Evans and colleagues recruited 99 children and their mothers from a rural and suburban area of the Northeast United States to participate in a 12-year longitudinal study, which tracked the children from ages 6 to 18.
When the children were 6 years old, the researchers assessed both the mothers’ and children’s proenvironmental behaviors and attitudes. Mothers completed the New Environmental Paradigm (NEP), a self-report measure of environmental attitudes, and the General Ecological Behavior (GEB) scale. The 6-year-olds completed modified versions of the NEP and GEB that used interactive games and pictures. The researchers also measured how much time the children spent outdoors and they collected data on mothers’ political ideology and educational attainment.
At age 18, 74 of the children returned to complete the second round of data collection. The young adults completed the same versions of the NEP and GEB scale that their mothers completed 12 years before.
The longitudinal data showed that individuals whose mothers had more proenvironmental attitudes demonstrated more proenvironmental behaviors themselves as young adults. Mothers’ educational attainment was also found to be an influential factor, although the researchers point out that there was low variance in the mothers’ level of education, as most had some post-college education and very few were high school dropouts.
As in past research, children who spent more time outdoors tended to report more environmentally responsible behavior and attitudes as adults. Evans and colleagues suggest that future studies should investigate whether different types of activities, such as fishing in wild nature versus gardening in the domestic outdoors, have divergent effects.
Interestingly, children’s environmental attitudes and behaviors at age 6 did not predict their behavior at 18. This could be due to potential methodological issues with the modified childhood measures, but another possibility, the researchers note, is that it simply takes time for these attitudes and behaviors to become stable.
Evans and colleagues note the significance of the results, explaining that “this is the first study to show that these parental factors matter for the eventual development of an adult’s engagement in proenvironmental behavior.”
Identifying early contributors to later environmentally responsible behaviors is a critical step in creating interventions, policies, and other strategies to improve these behaviors on a local, regional, and global scale.

Meeri Kim: Much of your work focuses on how children’s environment affects their health and well-being — in particular, the ways in which childhood poverty can lead to negative developmental outcomes. What are the components of poverty that tend to hit kids the hardest?
Gary Evans: Throughout my work, I’ve tried to make the point that one of the reasons why poverty is harmful for kids is the chronic stress they experience as a result. One of the things that is unique and unfortunately quite powerful about childhood poverty is this accumulation of stressors, both physical and psychosocial. Physical stressors include housing issues, noise, crowding, and pollution. But the kids also experience psychosocial stressors like crime, family turmoil, and residential instability.
“Parts of the brain may change in children who grow up in poverty, leading to less efficient control and regulation of some cognitive and emotional processes than their wealthier peers.”
MK: How does constant exposure to such stressors impact the developing brain?
GE: The physiological response systems that are designed to handle relatively infrequent environmental stressors become overwhelmed for disadvantaged children. There is good evidence that parts of the brain linked to executive control — involved in coordinating things and keeping everything organized — are sensitive to chronic stress. Structurally as well as functionally, these regions may change in children who grow up in poverty, leading to less efficient control and regulation of some cognitive and emotional processes than their wealthier peers.
At the same time, other parts of the brain tied to automated, quick responses to stress and emergencies like the amygdala become over-developed and over-activated. So you have this bad mix of heightened emotional responses coupled with less regulation and control.
MK: Recently, you published a study on the link between childhood poverty and adult psychological well-being. What did you find?
GE: I looked at the psychological well-being of 24-year-olds in relation to their family income when they were 9 years old, finding relationships with a number of mental health and cognitive outcomes. Childhood poverty is linked to deficits in adult memory, greater psychological/physiological distress, and higher levels of aggression.
Another research interest is how motivation and helplessness differ for those who grew up in an impoverished environment. We have given both children and adults age-appropriate tasks to persist on, and we see consistently less persistence from the disadvantaged. When challenged, they’re much more likely to give up. To me, that unfortunately fits our model — if you grow up with a lot of stressors, your environment sets you up for feeling like you don’t have a sense of mastery or self-efficacy. This is a dynamic, particularly for children, that we need to look more at.
“If you grow up with a lot of stressors, your environment sets you up for feeling like you don’t have a sense of mastery or self-efficacy.”
MK: Given your findings on poverty, what kinds of policy changes could help enhance these children’s lives? Universal basic income?
GE: Various experiments have shown that when you increase the income of families in poverty, you may get better health outcomes, better parenting, and reductions in various negative outcomes. I believe any policy approach has to increase income in a way that is predictable and reliable, coupled with more available and affordable services for these families.
“Because poverty includes a convergence of multiple risk factors and stressors, it really means multiple interventions are necessary.”
Because poverty includes a convergence of multiple risk factors and stressors, it really means multiple interventions are necessary. You can’t just provide housing or job training. You really have to look across the board. A classic example is taking people off of welfare and giving them a low-income job, which is usually right around the minimum wage. However, if there is little or no childcare, the program winds up not being nearly as effective as it ought to be. Good-quality free or heavily subsidized childcare coupled with employment or job training may work better.
A large and growing body of research shows that poor kids grow up to have a host of physical problems as adults.
Now add psychological deficits to the list, Cornell researchers say.
Childhood poverty can cause significant psychological deficits in adulthood, according to a sweeping new study. The research, conducted by tracking participants over a 15-year period, is the first to show this damage occurs over time and in a broad range of ways.
Impoverished children in the study had more psychological distress as adults, including more antisocial conduct like aggression and bullying and more helplessness behavior, than kids from middle-income backgrounds. Poor kids also had more chronic physiological stress and more deficits in short-term spatial memory.
“What this means is, if you’re born poor, you’re on a trajectory to have more of these kinds of psychological problems,” said Gary Evans, the author of the study and the Elizabeth Lee Vincent Professor of Human Ecology, and professor in the departments of design and environmental analysis, and human development.
Why? In a word, stress.
“With poverty, you’re exposed to lots of stress. Everybody has stress, but low-income families, low-income children, have a lot more of it,” Evans said. “And the parents are also under a lot of stress. So for kids, there is a cumulative risk exposure.”
Evans, a child psychologist who specializes in the effects of stress on children, is the author of “Childhood poverty and adult psychological well-being,” published Dec. 12 in the Proceedings of the National Academic of Sciences (PNAS).
The findings are important because kids who grow up in poverty are likely to stay impoverished as adults, Evans said. For example, there’s a 40 percent chance that a son’s income will be the same as his father’s income. That’s because the United States has the least social mobility of any wealthy Western democracy, he said.
“People walk around with this idea in their head that if you work hard, play by the rules, you can get ahead,” Evans said. “And that’s just a myth. It’s just not true.”
In his study, Evans tested 341 participants, all white, at ages 9, 13, 17 and 24.
Short-term spatial memory was tested by asking adult study participants to repeat increasingly complex sequences of lights and sounds by pressing four colored pads in the correct order – similar to the “Simon” game. The adults who grew up in poverty had a diminished ability to recall the sequences, compared to those who did not.
“This is an important result because the ability to retain information in short-term memory is fundamental to a host of basic cognitive skills, including language and achievement,” Evans wrote.
Although the participants were assessed on this measure only when they were adults, this test had the strongest association with childhood poverty of the four measures.
Helplessnesswas assessed by asking the participants to solve an impossible puzzle. Adults who grew up in poverty gave up 8 percent quicker than those who weren’t poor as kids. Previous research has shown chronic exposure to uncontrollable stressors – such as family turmoil and substandard housing – tends to induce helplessness.
Mental healthwas measured with a well-validated, standardized index of mental health with statements including “I argue a lot” and “I am too impatient.” Adults who grew up in poverty were more likely to agree with those questions than adults from a middle-income background.
Chronic physiological stress was tested by measuring the participants’ blood pressure, stress hormones and body mass index. Adults who grew up in poverty had a higher level of chronic physical stress throughout childhood and into adulthood.
The study has two implications, Evans said. First, early intervention to prevent these problems is more efficient and more likely to work.
“If you don’t intervene early, it’s going to be really difficult and is going to cost a lot to intervene later,” he said.
Second, increasing poor families’ incomes is the most efficient way to reduce a child’s exposure to poverty and, in turn, their risk of developing psychological problems. Evans supports the creation of a safety net, similar to Social Security’s supplemental income for the elderly and disabled. If a family is poor and has children, the federal government should provide them with supplementary income sufficient to participate in society, he said.
“It’s not true you can’t do anything about poverty. It’s just whether there’s the political will, and are people willing to reframe the problem, instead of blaming the person who is poor and – even more preposterous – blaming their children,” he said.
“This is a societal issue, and if we decide to reallocate resources like we did with the elderly and Social Security, we could change the kind of data this study is showing,” he said.
“Could we get rid of poverty? Probably not,” Evans said. “But I think we could change it dramatically.”
