Why diets fail?: From a perspective of social cognition

我们探讨了增强自我控制冲突是否会促进目标追求。在实验1中，当参与者被告知不要吃实验者展示的糖果中最诱人的糖果时，我们评估了a-淀粉酶。在实验2中，我们评估了对高/低热量食物的内隐态度。在实验3中，我们操纵了自我控制冲突的强度。如果电脑屏幕上的图片属于食物类别（如沙拉、巧克力），一半的参与者被要求朝他们拉动操纵杆。其余的参与者被要求如果图片属于健康类（如沙拉）就拉操纵杆，如果图片属于美味类（如巧克力）就推操纵杆。在实验1和实验2中，结果表明那些感知到更多冲突的人在自我控制方面取得了成功。但在实验3中，结果表明，那些感受到更多冲突的人自控能力较差。

We explored whether enhancing self-control conflict promotes goal-pursuit. In experiment 1, we assessed a-amylase when participants told not to eat the most attractive candy of the candies which experimenter presented. In experiment 2, we assessed implicit attitudes toward high/ low calorie foods. In experiment 3, we manipulated the strength of self-control conflict. Half of the participants were asked to pull a joystick toward them if picture on computer screen was part of the category of food (e.g., salad, chocolate). The rest of the participants were asked to pull a joystick if the picture was part of the category of healthy (e.g., salad) and to push it if the picture was part of the category of tasty (e.g., chocolate). In experiment 1 & 2, results indicated that those who perceived more conflict succeeded in self-control. But in experiment 3, results indicated that those who perceived more conflict failed self-control.
