我们通过使用优先观察技术，探索了婴儿识别日常食物（包括草莓和西红柿）气味的能力。实验1是在草莓上市季节（3月至6月）进行的，目的是提高参与者在实验室外接触草莓的频率。 37 名 6-8 个月大的婴儿接受了由两张并排放置的草莓和西红柿照片组成的刺激进行测试，并伴有草莓气味、西红柿气味或无气味。当婴儿闻到相同的气味时，他们会表现出对草莓图片的偏好，但对番茄图片则没有这种偏好。这些结果表明，即使是年幼的婴儿也能识别嗅觉-视觉的一致性。我们在草莓淡季（7月至9月）期间进行了实验2，以减少参与者在日常生活中接触草莓的机会。对 26 名 6-8 个月大的婴儿进行了测试，刺激物由两张并排放置的草莓和西红柿照片组成，并伴有草莓气味或没有气味。在实验2中，嗅觉-视觉结合效应消失了。这意味着视觉-嗅觉结合是由观察者的经验触发的。
We explored the ability of infants to recognize the smell of daily foods, including strawberries and tomatoes, by using a preferential-looking-technique. Experiment 1 was conducted while strawberries were in season (from March to June) in order to enhance the frequency of participant exposure to strawberries outside of the laboratory. Thirty-seven infants aged 6–8months were tested with a stimulus composed of a pair of photos of strawberries and tomatoes placed side by side and accompanied by a strawberry odor, a tomato odor, or no odors. Infants showed a preference for the strawberry picture when they smelled the congruent odor, but no such preference for the tomato picture. These results suggest that even young infants can recognize olfactory–visual congruency. We conducted Experiment 2 while strawberries were out of season (from July to September) to reduce participant exposure to strawberries in their daily life. Twenty-six infants aged 6–8months were tested with a stimulus composed of a pair of photos of strawberries and tomatoes placed side by side and accompanied by a strawberry odor, or no odors. In Experiment 2, the olfactory–visual binding effect disappeared. This implies that visual–olfactory binding is triggered by an observer’s experience.
