Abstract
We are developing a computer-based visual display system for behavioral experiments with pigeons. This system consisted of a 14 inch color CRT monitor and an experimental chamber with three clear response keys mounted on the transparent key panel. Three color circles were presented on the screen of the monitor, which corresponded to each of the three response keys. The monitor was placed behind the front panel of the chamber so that each stimulus presented on the screen of the monitor could be viewed from any position through the transparent key panel. In this system, a keypecking response was successfully shaped by the method of successive approximations and the pecking response could be well maintained under various procedures such as successive discrimination and delayed matching-to-sample tasks.
