Pigeons discriminated between stimulus changes dependent on their pecking and stimulus changes occurring independently of their behavior. Their performance was accurate, and when the payoffs for "hits" and "correct rejections" were varied, their response bias varied in a fashion similar to that of human observers detecting signals in a background of noise.
鸽子能够区分取决于其啄击行为的刺激变化和独立于其行为发生的刺激变化。它们的表现是准确的，并且当“击中”和“正确拒斥”的收益发生变化时，它们的反应偏差会以类似于人类观察者在噪声背景中检测信号的方式发生变化。
