Pigeons pecked at small forms displayed on an oscilloscope screen under computer control. The birds were required to find a small o amid varying numbers of x forms. A photocell glued to the bird's beak provided a signal to the computer when the beak approached a form, and the computer recorded the time and target of the response. As in some similar studies with human subjects, erros and reaction times increased with number of x forms displayed. The method appears promising for further studies of search and of other processes related to perception and information-processing in birds.
鸽子在计算机控制下啄食示波器屏幕上显示的小图形。这些鸟需要在不同数量的x图形中找到一个小o。当鸟喙接近一个图形时,粘在鸟喙上的光电管会向计算机发送信号,计算机记录反应的时间和目标。与一些针对人类受试者的类似研究一样,错误和反应时间随着显示的x图形数量增加而增加。该方法对于进一步研究鸟类的搜索以及与感知和信息处理相关的其他过程似乎很有前景。
