摘要: There is increasing evidence that individual differences in tendency to overeat relate impulsivity, possibly by reactivity food-related cues the environment. This study tested whether acute exposure food enhanced impulsive and risky responses women classified on overeat, indexed scores three factor eating questionnaire disinhibition (TFEQ-D), restraint (TFEQ-R) hunger scales. Ninety six healthy completed two measures of responding (delayed discounting, DDT a Go No-Go, GNG, task) measure decision making (the balloon analogue risk task, BART) as well behaviour either after looking at series pictures or visually matched controls. Impulsivity (DDT) risk-taking (BART) were both positively associated with TFEQ-D scores, but cases this effect was exacerbated prior cues. No effects found. also related more commission errors while restrained slower neither modified cue exposure. Overall these data suggest act enhance general overeating tentatively an important interaction between for may help explain key underlying overeating.
