The BBC Radio 4 programme Mind Changers has just released an audio podcast, Walter Mischel’s Marshmallow Study. Mischel (left), currently Niven Professor of Humane Letters in Psychology at Columbia University, began his now famous “marshmallow experiments” in the late 1960s and 1970s. In these experiments children were offered a marshmallow or, if they would wait, two marshmallows. Whether a child could resist eating the marshmallow, and the length of time over which they could delay gratification were then recorded. These findings were then analyzed in relation to the child’s future success. The findings from Mischel’s marshmallow experiments have been influential with respect to decision-making, self-control, and “willpower” research. The Mind Changers podcast on Mischel’s research is described as follows:
The psychologist Walter Mischel made his name with his ground-breaking book, Personality and Assessment, in 1968. He followed up with a classic experiment which is still running today.
Seeking to understand how the impulsive behaviour of his own three daughters at age 3 became increasingly regulated and planned by age 4 or 5, Mischel set up his experiment in delayed gratification at the Bing Nursery at Stanford University. Over 6 years he asked more than 300 4-year-olds to decide whether to have one marshmallow right now, or wait and get two, and he examined the cognitive processes which enabled some children to wait.
Hearing by chance how these 4-year olds were getting on in high school years later, Mischel realized that whether or not they’d been able to resist eating one marshmallow in order to get two was now showing a strong correlation with their achievements at school, and even with whether or not they were over-weight. Following the same cohort at 10-year intervals, he’s shown that those who were able to hang on for two marshmallow were less likely to drop out of college, use cocaine, or even go to prison.
