对食物线索的注意偏差可能是儿童肥胖的一个危险因素，但很少有范式来衡量幼儿的这种偏差。因此，本研究采用眼动视觉搜索任务来测量幼儿的注意偏向。51名3-6岁儿童玩游戏，在食物（实验条件）或玩具（控制条件）干扰中找到一个目标卡通人物。儿童在两次单独的访问中以随机顺序完成了实验和玩具条件。行为（反应延迟）和眼跟踪措施（初始方向，初始固定，累积固定）的注意食物和玩具线索进行了计算。回归用于测试对食物与玩具线索的注意力偏差，以及对食物线索的注意力偏差是否与当前BMI z分数相关。儿童花更多的累积时间看食物与玩具干扰，并需要更长的时间来确定目标时，通过食物与玩具干扰搜索。与玩具分心物相比，儿童更快地专注于他们的第一个食物与更高的BMI z分数相关。使用基于游戏的范式，采用眼动追踪，我们发现了一个行为的注意偏向，食物与玩具分心幼儿。此外，对食物线索的注意力偏差与当前BMI z评分相关。
Attentional bias to food cues may be a risk factor for childhood obesity, yet there are few paradigms to measure such biases in young children. Therefore, the present work introduces an eye-tracking visual search task to measure attentional bias in young children. Fifty-one 3–6-year-olds played a game to find a target cartoon character among food (experimental condition) or toy (control condition) distractors. Children completed the experimental and toy conditions on two separate visits in randomized order. Behavioral (response latencies) and eye-tracking measures (initial orientation, initial fixation, cumulative fixation) of attention to food and toy cues were computed. Regressions were used to test for attentional bias to food versus toy cues, and whether attentional bias to food cues was related to current BMI z-score. Children spent more cumulative time looking at food versus toy distractors and took longer to locate the target when searching through food versus toy distractors. The faster children fixated on their first food versus toy distractor was associated with higher BMI z-scores. Using a game-based paradigm employing eye-tracking, we found a behavioral attentional bias to food vs. toy distractors in young children. Further, attentional bias to food cues was associated with current BMI z-score.
