Marshmallows Predict Future Success?

Marshmallows predict future success? Well, not the marshmallows themselves, but marshmallows were used as an appetitive stimuli in studies of delayed gratification to predict future success. Walter Mischel conducted the original "marshmallow experiment" in 1966, yet the experimental process has been replicated numerous times and continues to be an active topic of research today (Powell, Honey, & Symbaluk, 2013, p. 412). The marshmallow experiment features a preschool-aged child sitting at a table, while a researcher enters and places a marshmallow in front of the child. The researcher tells the child that they can eat the single marshmallow now, or can wait until the researcher returns and receive two marshmallows. Waiting for the second marshmallow, an example of the demonstration of delayed gratification, has been linked to adolescent success and social and cognitive competencies. The children who display delayed gratification, and waiting for the research returned to receive two marshmallows, were shown in adolescence to be more, "academically and socially competent, verbally fluent, rational, attentive, playful, and able to deal with frustration" (Mischel, Shoda, & Peake, 1988). The competencies displayed by children who demonstrate delayed gratification in their preschool years caused for national and international attention, especially in the past ten years, as the concept of delayed gratification was included in parenting texts and news broadcasts. It still is to be discovered the causal explanation for why delayed gratification results in greater future success, yet it teaches us all something about the importance of development during the preschool years and the behaviors that we reinforce for our children during that time.

  1. This read was very interesting and the video was very humorous but its looked like all the older kids who were able to comprehend the word "wait" and "more" were more successful. The two younger girls ate right away, probably too young to follow directions or cared less to wait for more. I think this experiment truly reflects the level of comprehension, and the ability to follow directions as well as making the "right" decision. The kids who waited, knew that there would be a greater reward, and having two marshmallows rather than settling for just one would be worth it in the end. I wonder if the parents of these kids, were shocked with their kids or if they knew exactly the reaction of their child. Perhaps those who waited are use to waiting so this experiment was easier or less stressful, whereas those less impatient were more stressed and had difficult time waiting, are not use to waiting.
