本研究旨在探讨斑胸草雀视觉辨别表现的不对称性。成年雄性和雌性斑胸草雀在鹅卵石地板测试中进行了测试，在一段时间的食物剥夺后，受试者必须在单目条件下区分珠子和食物颗粒。左眼的鸟比右眼的和双筒望远镜的鸟啄珠子的次数更多，但这只是在测试的最后一部分。右眼鸟的良好表现可以被理解为大脑左半球对食物进行分类的能力更高，正如已经提出的小鸡和鸽子一样。然而，在任务开始时没有差异支持了不同信息处理模式的假设，比如对新颖性的反应突出涉及右半球。(C) 1998出版Elsevier Science B.V.版权所有
The aim of the study was to investigate the asymmetries of visual discrimination performance in zebra finches. Adult male and female zebra finches were tested on the pebble floor test, where the subjects must distinguish between beads and food grains under monocular conditions after a period of food deprivation. Left-eyed birds pecked at beads more than right-eyed and binoculars, but only during the last part of the test. The better performance of the right-eyed birds can be understood as the higher ability of the left hemisphere of the brain to categorize food, as has been already suggested for chicks and pigeons. Nevertheless, the absence of differences at the beginning of the task support the hypothesis of different modes of information processing, such as a prominent involvement of the right hemisphere in response to novelty.
