In this study, we hypothesized that overweight/obese persons have an exaggerated approach tendency toward high calorie foods. Testing this hypothesis, a stimulus response compatibility (SRC) task was used to assess approach-avoidance tendencies toward food in both overweight/obese participants (n=42), and normal weight controls (n=46). The SRC task is a reaction time task measuring how fast one approaches and avoids pictures of food and non-foods according to given instructions. It was found that overweight/obese men are slower at avoiding particularly high calorie snack foods. But this does not appear to be the case for overweight/obese women who showed nearly as fast avoidance as approach toward the high calorie food cues. It is concluded that overweight/obese women, rather than men, are ambivalent toward high calorie foods, which is the likely result of high dietary restraint.
在这项研究中，我们假设超重/肥胖者对高热量食物有过度的趋近倾向。为了验证这一假设，我们使用了一种刺激反应相容性（SRC）任务来评估超重/肥胖参与者（n=42）和正常体重对照组（n=46）对食物的趋近-回避倾向。SRC 任务是一种反应时任务，用于根据给定的指令测量一个人对食物和非食物图片的趋近和回避速度。结果发现，超重/肥胖男性在回避特别高热量的零食时反应较慢。但这似乎不适用于超重/肥胖女性，她们对高热量食物线索的回避速度几乎与趋近速度一样快。研究得出结论，超重/肥胖女性对高热量食物犹豫不决，而不是男性，这可能是由于高饮食抑制所致。
