| Outline of Final Research Achievements |
This research deals with the problem of why it's hard to change unhealthy behavior. Although many people keep trying various weight loss efforts, not many realize that it has effective results and health benefits. In order to examine cognitive biases in dieters, study 1 compared the CRT(Frederick, 2005) scores for 900 dieters and 900 non-dieters( all females in range 15-59 years). No significant difference was seen between two samples, although dieters showed lower scores than non-dieters. Study 2 examined the role of impulsiveness( Dickman, 2000; Fossati et al., 2001) in analytic thinking for another two samples of dieters and non-dieters( each 540 females). Maladaptive impulsivity scores correlated with low CRT scores significantly. Although cognitive biases were not showed directly in dieters, it was showed that impulsiveness has important function to bridge System1 thinking with dieting behavior.
