Success in tasks requiring categorization of pictorial stimuli does not prove that a subject understands what the pictures stand for. The ability to achieve representational insight is by no means a trivial one because it exceeds mere detection of 2-D features present in both the pictorial images and their referents. So far, evidence for such an ability in nonhuman species is weak and inconclusive. Here, the authors report evidence of representational insight in pigeons. After being trained on pictures of incomplete human figures, the birds responded significantly more to pictures of the previously missing parts than to nonrepresentative stimuli, which demonstrates that they actually recognized the pictures' representational content.
在需要对图片刺激进行分类的任务中取得成功，并不能证明受试者理解图片所代表的含义。获得表象洞察力的能力绝非微不足道，因为它不仅仅是检测图片图像及其所指对象中都存在的二维特征。到目前为止，非人类物种具有这种能力的证据薄弱且尚无定论。在此，作者报告了鸽子具有表象洞察力的证据。在对不完整人体图片进行训练后，这些鸟类对先前缺失部分的图片的反应明显比对非代表性刺激的反应更多，这表明它们实际上识别出了图片的表象内容。
