Because of inconsistencies in the field of attentional bias to food cues in eating behavior, this study aimed to re-examine the assumption that hungry healthy weight individuals have an attentional bias to food cues, but satiated healthy weight individuals do not. Since attentional engagement and attentional disengagement have been proposed to play a distinct role in behavior, we used a performance measure that is specifically designed to differentiate between these two attentional processes. Participants were healthy weight women who normally eat breakfast. In the satiated condition (n = 54), participants were instructed to have breakfast just before coming to the lab. In the fasted condition (n = 50), participants fasted on average 14 h before coming into the lab. Satiated women showed no stronger attentional engagement or attentional disengagement bias to food cues than to neutral cues. Fasted women did show stronger attentional engagement to food cues than to neutral cues that were shown briefly (100 ms). They showed no bias in attentional engagement to food cues that were shown longer (500 ms) or in attentional disengagement from food cues. These findings are in line with the assumption that healthy weight individuals show an attentional bias to food cues when food stimuli are motivationally salient. Furthermore, the findings point to the importance of differentiating between attentional engagement and attentional disengagement.
由于在进食行为中对食物线索的注意力偏向方面存在不一致,本研究旨在重新检验以下假设,即饥饿的健康体重个体对食物线索存在注意力偏向,而饱腹的健康体重个体则不存在。由于注意力的投入和注意力的脱离被认为在行为中起着不同的作用,我们使用了一种专门设计的绩效指标来区分这两种注意力过程。参与者是正常吃早餐的健康体重女性。在饱腹状态下(n=54),参与者被指示在来实验室之前吃早餐。在禁食状态下(n=50),参与者平均在来实验室前禁食 14 小时。饱腹女性对食物线索的注意力投入或注意力脱离偏向与中性线索没有更强。与短暂(100 毫秒)显示的中性线索相比,禁食女性对食物线索的注意力投入更强。她们对较长时间(500 毫秒)显示的食物线索或对食物线索的注意力脱离没有表现出注意力投入偏向。这些发现与健康体重个体在食物刺激具有动机显著性时对食物线索表现出注意力偏向的假设一致。此外,这些发现指出区分注意力投入和注意力脱离的重要性。
