Showing weight-conscious women pictures of sweet treats actually strengthens their resolve to eat healthily, rather than encouraging them to cheat. To test out this theory, Kroese and her colleagues asked 54 female students to look at a picture of either a slice of chocolate cake or a flower under the guise of a memory test. The researchers then questioned the students about any plans to eat more healthily and offered them a choice between a chocolate or oatmeal cookie. Images of brief cases will make people more competitive. Smell of cleaning makes people feel cleaner.
