For the unintiaiated, the “marshmallow test” was an experiment conducted with preschool children to establish what their ability to exercise self-control to wait for a larger reward was. In the original experiment, this was one marshmallow (or similar treat) as soon as they wanted, or double this if they waited until an adult returned to the room.
But crucially, the research underpinning The Marshmallow Test is that self-control at a very early age has a strong impact on outcomes throughout life. Those who can delay gratification for 20 minutes for a greater reward at a young age on average achieve better qualifications, save more for retirement and manage more stable relationships.
Mischel then sets out to understand what factors effect self control, from genes through stress levels in infancy, to factors under the control of adults. He tests public policies, parenting techniques and ways to control your thinking process to allow slower thinking to step into decision making. Thinking Fast and Slow was referenced, along with other research into how we control impulsive decision making and step back.
I found this an interesting read, and am glad I picked it up from the library.
