The ability to detect food plays an indispensable role in our survival and wellbeing. Previous psychological studies have revealed that food is detected more rapidly than non-food items. However, whether the detection of food could be modulated by cultural factors remains unknown. We investigated this issue in the present study using a visual search paradigm with Polish and Japanese participants. Photographs of international fast food, domestic Japanese food, or kitchen tools were presented alongside images of non-food distractors (cars). Participants were asked to judge whether the stimuli were all identical or not. The reaction time data showed that participants from both cultures detected food more rapidly than kitchen tools. Japanese participants detected fast food more rapidly than Japanese food, whereas Polish participants did not display such differences between food types. These results suggest that rapid detection of food is universal, but is modulated by cultural experiences.
食物觉察能力在我们的生存和健康中起着不可或缺的作用。先前的心理学研究表明，食物比非食物物品更快被觉察到。然而，食物的觉察是否可以被文化因素所调节尚不清楚。本研究采用视觉搜索范式，使用波兰和日本参与者，对这一问题进行了研究。参与者需要判断呈现的刺激是否全部相同，刺激包括国际快餐、日本国内食物或厨房工具的照片，以及非食物干扰物（汽车）的图像。反应时间数据显示，来自两种文化的参与者都比厨房工具更快地觉察到食物。日本参与者比日本食物更快地觉察到快餐，而波兰参与者则没有显示出食物类型之间的这种差异。这些结果表明，快速觉察食物是普遍的，但受到文化经验的调节。
