The author's purpose was to examine children's recognition of emotional facial expressions, by comparing two types of stimulus: photographs and drawings. The author aimed to investigate whether drawings could be considered as a more evocative material than photographs, as a function of age and emotion. Five- and 7-year-old children were presented with photographs and drawings displaying facial expressions of 4 basic emotions (i.e., happiness, sadness, anger, and fear) and were asked to perform a matching task by pointing to the face corresponding to the target emotion labeled by the experimenter. The photographs we used were selected from the Radboud Faces Database and the drawings were designed on the basis of both the facial components involved in the expression of these emotions and the graphic cues children tend to use when asked to depict these emotions in their own drawings. Our results show that drawings are better recognized than photographs, for sadness, anger, and fear (with no difference for happiness, due to a ceiling effect). And that the difference between the 2 types of stimuli tends to be more important for 5-year-olds compared to 7-year-olds. These results are discussed in view of their implications, both for future research and for practical application.
照片和图画，来研究儿童对情感面部表情的识别。作者旨在调查图画是否能被视为比照片更具启发性的材料，这取决于年龄和情感。向5岁和7岁的儿童展示呈现4种基本情绪（即快乐、悲伤、愤怒和恐惧）面部表情的照片和图画，并要求他们通过指向与实验者标记的目标情绪相对应的面孔来完成匹配任务。我们使用的照片选自拉德堡德面部数据库，图画是根据表达这些情绪所涉及的面部成分以及儿童在被要求在自己的图画中描绘这些情绪时倾向使用的图形线索设计的。我们的结果表明，对于悲伤、愤怒和恐惧，图画比照片更容易被识别（对于快乐没有差异，由于天花板效应）。而且与7岁儿童相比，两种刺激类型之间的差异对5岁儿童来说往往更显著。鉴于这些结果对未来研究和实际应用的影响，我们对其进行了讨论。
