Can the kids wait? Today's youngsters are able to delay gratification longer than those of the 1960s, research finds. Researchers wonder if digital technology, preschool education, parenting may enhance self-control.
- The children of today are able to delay gratification longer than children in the 1960s and 1980s.
- This finding contrasts the notion that today's children have less self-control than previous generations.
- Experts claim that digital technology, preschool education, and parenting may enhance self-control.





The ability to delay gratification in early childhood has been associated with a range of positive outcomes in adolescence and beyond. These include greater academic competence and higher SAT scores, healthier weight, effective coping with stress and frustration, social responsibility and positive relations with peers.
Carlson and her colleagues looked at results from the original marshmallow test, as well as replications conducted in the 1980s and early 2000s. In defiance of expectations, kids who participated in their studies in the 2000s waited an average of two minutes longer (during a 10-minute period) than those from the 1960s, and one minute longer than those tested in the 1980s.
Interestingly, today's adults thought that children nowadays would be more impulsive and less able to wait, Carlson found. She and her associates conducted an online survey of 358 U.S. adults who were asked how long they thought children today would wait for a larger treat compared with kids in the 1960s. Approximately 72 percent thought children today would wait less long, and 75 percent believed that children today would have less self-control.
"Our findings serve as an example of how our intuition can be wrong and how it's important to do research," said co-author Yuichi Shoda, PhD, of the University of Washington. "If we hadn't been systematically collecting data on how long children wait in this type of experiment, and if we hadn't analyzed the data, we would not have found these changes. They pose an interesting and important question for future research to understand: Are the changes we found in our sample unique, or do they apply more broadly to children from more diverse backgrounds? What is causing the change, and what are the mechanisms through which these changes occur?"
The researchers offered several possible explanations for why children in the 2000s waited longer than those in prior decades. They noted a statistically significant increase in IQ scores in the last several decades, which has been linked to rapidly changing technologies, increased globalization and corresponding changes in the economy. At a more psychological level, increases in abstract thought, which are associated with digital technology, may contribute to executive function skills such as delay of gratification, they said.
Parenting style also has changed in ways that help promote the development of executive function, such as being more supportive of children's autonomy and less controlling, the researchers noted.
"We believe that increases in abstract thought, along with rising preschool enrollment, changes in parenting and, paradoxically, cognitive skills associated with screen technologies, may be contributing to generational improvements in the ability to delay gratification," Carlson said. "But our work is far from over. Inequality persists in developmental outcomes for children in poverty."
Walter Mischel, of Columbia University, who also co-authored this paper, noted that "while the results indicate that the sampled children's ability to delay is not diminished on the marshmallow test, the findings do not speak to their willingness to delay gratification when faced with the proliferation of temptations now available in everyday life."
