Researchers often argue for the existence of “captivity bias”: a higher success rate that may be observed for nonhumans tested in captivity compared to those tested in nature, purportedly because the former have certain advantages that the latter lack. Rössler et al. (Scientific Reports 10, 8681, 2020) find that, at least for Goffin’s cockatoos (Cacatua goffiniana), differences exist in motivation, not in problem-solving ability.

囚禁是否会改变高芬美冠鹦鹉的解决问题行为？

研究人员经常争辩说存在“圈养偏见”的存在：在人工圈养下进行测试的非人类患者与在自然条件下进行测试的人类相比，成功率可能更高，据称这是因为前者具有后者缺乏的某些优势。Rössler等。（科学报告10，8681，2020）发现，至少对于戈芬的美冠鹦鹉（Cacatua goffiniana），动机存在差异，而解决问题的能力却存在差异。
