For decades, studies have shown that children able to resist temptation鈥攐pting to wait for two marshmallows later rather than take one now鈥攖end to do better on measures of health and success later in life.

But 50 years after the seminal 鈥渕arshmallow test鈥� suggested this, a fresh, multicultural approach to the test adds a missing piece of the story: What kids are willing to wait for depends largely on their cultural upbringing.

The 抖阴短视频 Boulder-led study, published in the journal , found that children in Kyoto, Japan, waited three times longer for food than for gifts, whereas children in Boulder, Colorado, waited nearly four times longer for gifts than for food.

鈥淲e found that the ability to delay gratification, which predicts many important life outcomes, is not just about variations in genes or brain development but also about habits supported by culture,鈥� said senior author Yuko Munakata, a research affiliate with the Department of Psychology and Neuroscience at 抖阴短视频 Boulder.

The findings provide good news to parents, showing that fostering simple, culturally appropriate habits in young children may influence their development in ways that make it easier for them to delay gratification later.

But it also calls into question decades of social science research, suggesting that some children deemed lacking in self-control may have instead just had different cultural values around waiting.

鈥淚t calls into question: How much of our scientific conclusions are shaped by the cultural lens we, as researchers, bring to our work?鈥� said Munakata.

Marshmallow test redux

First conducted in the early 1970s by psychologist Walter Mischel, the marshmallow test worked like this: A preschooler was placed in a room with a marshmallow, told they could eat the marshmallow now or wait and get two later, then left alone while the clock ticked and a video camera rolled.听

While research is mixed, many studies found that preschoolers who waited longer did better on academic test scores, were less likely to exhibit problem behavior and had a healthier body mass index and better relationships later in life. Some studies also found that these same study subjects were less likely to end up in jail and made more money.

Early on, researchers focused on inherent and cognitive explanations.

鈥淭here was this idea that some kids simply have more self-control, and some kids have less,鈥� said Munakata, now also a professor of psychology at University of California, Davis.听

Munakata, who has Japanese heritage but grew up in the U.S., conceived of the idea of the new study while on sabbatical in Kyoto. On the first day of school, as her two young children tore into their lunchboxes, their peers quickly set them straight, telling them that in Japan no one ate until everyone sat down.

In contrast, while her children were used to waiting to open their gifts on birthdays and Christmas, their Japanese peers tended to open them the moment they got them, whether the gift-giver was present or not.

How much does culture influence what we鈥檒l wait for?

To find out, she teamed up with Professor Satoru Saito at the Graduate School of Education in Japan and Kaichi Yanaoka, then a graduate student at University of Tokyo.

They recruited 144 children from Boulder and Kyoto, randomly assigning each to a test involving either a marshmallow or a wrapped present. Researchers and parents looked on through a video feed.

鈥淥ne counted the dots on the ceiling. Another drew his name on the desk. Another paced around the room,鈥� said co-author Grace Dostart, a professional research assistant with the听
Ren茅e Crown Wellness Institute, who helped run the Boulder study.

鈥淚t was fascinating to see the self-soothing techniques these kids engaged in.鈥�

The power of politeness

The children in Japan were overwhelmingly better at waiting for the marshmallow, with a median wait time of 15 minutes.

鈥淚f we had just looked at their behavior with the sweets, it would have looked like Japanese kids have better self-control,鈥� said Munakata. 鈥淏ut that was not the end of the story.鈥�

In Japan, kids waited less than five minutes to open the present.

The reverse was true in the U.S., with kids waiting almost 15 minutes to open the present vs. less than four to gobble the marshmallow.

Notably, kids who had a habit of waiting for meals at home and elsewhere waited longer to eat the marshmallow. And, across cultures, children who were more attuned to social conventions (as measured by surveys of children) waited longer.

鈥淭his suggests that the way you grow up, the social conventions you are raised around and how much you pay attention to them, are all important,鈥� said Dostart.听

Munakata said the study does not debunk the marshmallow test鈥檚 central finding: That the ability to resist here-and-now rewards is linked to success in long-term goals. And she acknowledges that genetics, neurocognitive factors and social factors play some role in how much willpower a child exhibits. (Her own 2018 study found that when other preschoolers in their 鈥渋n-group鈥� opt to wait for the second marshmallow, they tend to also).

But there are things parents and caregivers can do to reap the benefits of better self-control.

鈥淐ultivating habits of waiting for others could be doing much more than supporting politeness,鈥� said Munakata, noting that such habits may change brain systems in ways that make delaying gratification more automatic. 鈥淚t could make it easier for kids to succeed in future life situations without having to work so hard.鈥�
