On the other hand, when the children were given a task which didnt distract them from the treats (group A, asked to think of the treats), having the treats obscured did not increase their delay time as opposed to having them unobscured (as in the second test). They took into account socio-economic variables like whether a child's mother graduated from college, and also looked at how well the kids' memory, problem solving, and verbal communication skills were developing at age two.
