Culture affects kids’ ability to delay gratification

Delayed gratification differs between cultures, research with American and Japanese children finds.

Overcoming impulses to enjoy immediate rewards in order to get later benefits is fundamental to achieving goals. Researchers often measure the delaying of gratification with well-known “marshmallow task,” in which children must resist the urge to eat one treat now in order to get more treats later.

Individual differences in this task predict important later life outcomes such as academic success, socioemotional competence, and health, many researchers agree.

As reported in the journal Psychological Science, researchers found that cultural habits around waiting to eat (emphasized in Japan) and waiting to open gifts (emphasized in the United States) shape distinct profiles of delaying gratification.

Japanese children waited three times longer for food than for gifts, whereas US children waited nearly four times longer for gifts than for food.

“Our findings offer new answers as to why delaying gratification predicts life outcomes and suggest new directions for understanding and shaping children’s delay of gratification,” write coauthors Yuko Munakata, professor of psychology, and Jade Yonehiro, a graduate student, both in the psychology department and the Center for Mind and Brain at the University of California, Davis.

In the context of eating food, Japanese people are accustomed to waiting. When having meals, Japanese people typically wait until all individuals are served. Such customs of waiting to eat food are not as prevalent in the daily experiences of children in the United States.

In the context of opening gifts, US children may experience waiting more consistently than Japanese children. Giving gifts is a more special event occurring on specific occasions in the United States, such as birthdays and other holidays, that can involve traditions of waiting. In contrast, gift giving is a regular year-round event for Japanese people that is not consistently associated with traditions of waiting.

In the study, 26 US children and 40 Japanese children were in the food experiment, and 32 US children and 40 Japanese children were in the gift experiment.

The researchers recruited participants in the United States from a database of families in Boulder, Colorado, and surrounding areas who expressed interest in participating in developmental research. They recruited Japanese participants from a database of families in Kyoto, Osaka, and surrounding areas from a research consulting company.

For the Japanese sample, researchers recruited only participants who had eaten a marshmallow before to ensure that all children were familiar with marshmallows.

The experimenter first placed a marshmallow on a plate or a gift box in front of the child, 4 inches from the table’s edge, and told the child if they could wait for the experimenter to get more marshmallows/gifts from another room, they could have two instead. If the child could wait the full 15 minutes without interacting with the marshmallow or the gift in any way they were rewarded with a second marshmallow/gift.

Japanese and US children showed distinct profiles of delaying gratification. As predicted, culture and reward interacted in children’s likelihood of delaying: Japanese children waited longer for delayed rewards in the food condition (median wait time was 15 minutes) than in the gift condition, where the wait time was almost five minutes.

In contrast, US children showed the reversed pattern. They waited longer for delayed rewards in the gift condition than in the food condition.

“Our findings support a novel perspective that delaying gratification is promoted by the strength of habits of waiting for rewards accumulated in an everyday context, not simply reflecting higher level processes that override temptations,” the researchers say.

This perspective raises implications for measurement and interpretation. Delay-of-gratification tasks may measure different psychological processes depending on the rewards and individuals involved. For example, for Japanese children, performance on the classic marshmallow test may mainly reflect the strength of habits of waiting to eat and sensitivity to social conventions. In contrast, their waiting to open a gift might be more influenced by self-control and trustworthiness.

“Our findings also have implications for shaping resistance to temptations,” the report continues. “Groups in each culture have unique social conventions that function to increase cohesion and cooperation. Such conventions require inhibiting behaviors toward personal needs or goals and implementing socially motivated behavior with affiliative functions. In addition, culture-specific parenting values and styles correlate with and may promote children’s delaying of gratification.”
