A strategy used in the marshmallow test was the focus on "hot" and "cool" features of an object. The children were encouraged to think about the marshmallow's "cool features" such as its shape and texture, possibly comparing it to a cotton ball or a cloud. The "hot features" of the marshmallow would be its sweet, sticky tastiness. These hot features make it more difficult to delay gratification. By focusing on the cool features, the mind is adverted from the appealing aspects of the marshmallow, and self-control is more plausible.
