Visual attention for food is likely to play an important role for overeating. The attentional bias for visual food stimuli was investigated with respect to self-reported restrained, external and emotional eating style. Using a Rapid Serial Visual Presentation task (N = 103), the effects of visual food stimuli in the context of the attentional blink were examined. Food targets enhanced the attentional blink when presented as first targets in a rapid stream of pictures and impaired the identification of preceding non-food targets in terms of a backward interference when presented as second targets. Task irrelevant food distractors interfered with the identification of subsequent non-food targets. The effects provide evidence for a prioritisation of food stimuli in the allocation of attentional resources. The attentional bias for food emerged as a universal phenomenon irrespective of personal eating style. Therefore, enhanced attention for visual food stimuli seems to play no direct causal role in eating styles associated with overeating.
视觉注意力对食物的关注很可能在暴饮暴食中起着重要作用。本研究旨在调查视觉食物刺激的注意力偏向与自我报告的约束型、外显性和情绪性进食风格之间的关系。研究采用快速序列视觉呈现任务（N=103），考察了在注意瞬脱背景下视觉食物刺激的影响。当食物目标作为快速呈现图片流中的第一个目标时，它们会增强注意瞬脱；当作为第二个目标时，它们会以前置非食物目标的反向干扰方式损害对其的识别，即产生后向干扰。任务无关的食物分心物会干扰对后续非食物目标的识别。这些结果为注意力资源分配中食物刺激的优先化提供了证据。无论个人的进食风格如何，对食物的注意力偏向都是一种普遍现象。因此，对视觉食物刺激的注意力增强似乎与暴饮暴食相关的进食风格没有直接的因果关系。
