We developed a video system for real-time detection of a pigeon's orientation and for reinforcement of a "turning response." Using this system, negative behavioral contrast was found across key-peck and turning responses. In addition, turning away from the pecking key was detected by the system just after presentation of the negative discriminative stimulus on the key. The results suggest that avoidance of the discriminative stimulus in the constant component, which has been regarded as a causal factor for negative contrast (additivity theory), is not the primary factor for negative behavioral contrast of pigeons' key pecking, but may account for negative local contrast.
我们开发了一个视频系统，用于实时检测鸽子的方向，并对“转向反应”进行强化。使用该系统，在啄键和转向反应中发现了负性行为对比。此外，在啄键上呈现负鉴别刺激后，系统立即检测到转向远离啄键。结果表明，回避恒常成分中的鉴别刺激（相加理论认为这是负对比的一个因果因素）并不是鸽子啄键负性行为对比的主要因素，但可能解释了负性局部对比。
