This 1960s research project was led by Prof Walter Mischel, a psychologist from Stanford University. In the 1960’s-1970’s, a psychologist, then Stanford professor named Walter Mischel conducted a series of important psychological studies. [10][11], A 2012 study at the University of Rochester altered the experiment by dividing children into two groups: one group was given a broken promise before the marshmallow test was conducted (the unreliable tester group), and the second group had a fulfilled promise before their marshmallow test (the reliable tester group). Report. Many children generated their own diversions: they talked quietly to themselves, sang, created games with their hands and feet, and even tried to go to sleep during the waiting time. Prior to the Marshmallow Studies at Stanford, Walter Mischel had shown that the child's belief that the promised delayed rewards would actually be delivered is an important determinant of the choice to delay, but his later experiments did not take this factor into account or control for individual variation in beliefs about reliability when reporting correlations with life successes.[13][14][15][16]. Mischel’s overarching paradigm, the Marshmallow Test, found that children have short- [9], A 2011 brain imaging study of a sample from the original Stanford participants when they reached mid-life showed key differences between those with high delay times and those with low delay times in two areas: the prefrontal cortex (more active in high delayers) and the ventral striatum (an area linked to addictions) when they were trying to control their responses to alluring temptations. In over 600 children who took part in the experiment, a minority ate the marshmallow immediately.
