In a post-scarcity world, energy intake and excesses therein are mediated by psychological mechanisms, such as implicit inclinations to approach certain foods. We investigated how food deprivation, calorie content and individual food preferences affect this approach bias. Sixty women performed a touchscreen-based approach-avoidance task featuring a wide range of food items, once while satiated and once while food-deprived for 15 h. We found an overall approach bias towards food that was not influenced by food deprivation or calorie density of the food items. Instead, we found that approach bias related to the participants' (lack of) desire to eat specific food items, and to a lesser extent to how much their general desire to eat changed due to food deprivation. Links with food preference were selective to trials in which foods had to be approached, and were absent in trials in which foods had to be avoided, pointing to selectivity to appetitive brain systems and clarifying the nature of the bias. Approach bias was unrelated to overall state or trait food craving. We conclude approach bias for appetitive stimuli may primarily express itself as speeded approach rather than slowed avoidance. Additionally, our results show there is merit in personalizing stimulus selection for approach bias measurement and retraining, as approach bias was concordant with individual food preferences, rather than objective calorie content.

吃特定食物的欲望会缓和食物方法的偏见
在后资源匮乏的世界中,能量摄入和其中的过量是由心理机制调节的,例如接近某些食物的隐性倾向。我们调查了食物匮乏、卡路里含量和个人食物偏好如何影响这种方法偏差。60 名女性执行了一项基于触摸屏的回避任务,其中包括各种食物,一次饱食一次,一次禁食 15 小时。我们发现整体方法偏向于不受食物匮乏或食物卡路里密度影响的食物。相反,我们发现这种方法偏差与参与者(缺乏)吃特定食物的欲望有关,并且在较小程度上与他们因食物匮乏而改变的总体食欲有关。与食物偏好的联系在必须接近食物的试验中是有选择性的,而在必须避免食物的试验中则不存在,这表明对食欲大脑系统的选择性并阐明了偏见的性质。方法偏差与总体状态或特征食物渴望无关。我们得出结论,对食欲刺激的趋近偏差可能主要表现为加速趋近而不是缓慢回避。此外,我们的结果表明,为方法偏差测量和再训练个性化刺激选择是有好处的,因为方法偏差与个人食物偏好一致,而不是与客观卡路里含量一致。方法偏差与总体状态或特征食物渴望无关。我们得出结论,对食欲刺激的趋近偏差可能主要表现为加速趋近而不是缓慢回避。此外,我们的结果表明,为方法偏差测量和再训练个性化刺激选择是有好处的,因为方法偏差与个人食物偏好一致,而不是与客观卡路里含量一致。方法偏差与总体状态或特征食物渴望无关。我们得出结论,对食欲刺激的趋近偏差可能主要表现为加速趋近而不是缓慢回避。此外,我们的结果表明,为方法偏差测量和再训练个性化刺激选择是有好处的,因为方法偏差与个人食物偏好一致,而不是与客观卡路里含量一致。
