However, an attempt to repeat the experiment suggests there were hidden variables that throw the findings into doubt. The results showed that the longer his 4- and 5-year-olds were able to resist the temptation presented by the first marshmallow, the better they performed in subsequent tests of educational attainment. It has been argued in the past that the test justified things such as delaying gratification, which is a middle- and upper-class value.

Those in group B were asked to think of fun things, as before. The refutation of the findings of the original study is part of a more significant problem in experimental psychology where the results of old experiments cant be replicated. This test differed from the first only in the following ways: The results suggested that children who were given distracting tasks that were also fun (thinking of fun things for group A) waited much longer for their treats than children who were given tasks that either didnt distract them from the treats (group C, asked to think of the treats) or didnt entertain them (group B, asked to think of sad things).
