五种无尾类蝌蚪在镜子中检查自己的视觉图像时，测试了眼睛使用的偏好。当在一个有几个小镜子的水箱中进行测试时，五种不同物种的蝌蚪（蟾蜍、绿蟾蜍、蛙、蛙、铃蟾）优先接近并定位自己，镜子位于他们的左侧，从而用左眼的单眼视野观看图像。用R.在一项简单的任务中，他们必须选择靠近位于他们左右两侧的两个大镜子中的一个。控制实验表明，行为的不对称性是由于电机的喜好，它是独立的形态不对称的位置的气门。这是第一次演示的功能性视觉偏侧幼年两栖动物在变态前。(C)2002 Elsevier Science B.V.保留所有权利。
Tadpoles of five anuran species were tested for preferences in the use of the eyes during inspection of their own visual image in a mirror. When tested in a tank with several small mirrors, tadpoles of five different species (Bufo bufo, Bufo viridis, Rana temporaria, Rana esculenta, Bombina variegata) preferentially approached and positioned themselves with the mirror located on their left side, thus looking at the image with the monocular field of their left eye. Similar results were obtained with tadpoles of R. temporaria tested in a simple task in which they had to choose approaching one or other of two large mirrors located on their left and right side. Control experiment showed that the behavioural asymmetry was not due to motor preferences and that it was independent of morphological asymmetries in the positions of the spiracles. This is the first demonstration of a functional visual lateralisation among juvenile amphibia before metamorphosis. (C) 2002 Elsevier Science B.V. All rights reserved.
