A psychophysical procedure was developed to test the olfactory capacities of the pigeon. The procedure employs symmetrical response contingencies, involves the confinement of the pigeon's head in the stimulus air stream and relies solely on positive reinforcement for the development and maintenance of discriminative responding. The absolute sensitivity of three pigeons to amyl acetate in air was measured. Thresholds for all three pigeons were between 10(-3.4) and 10(-3.6) of vapor saturation.
开发了一种心理物理学程序来测试鸽子的嗅觉能力。该程序采用对称的反应条件，将鸽子的头部限制在刺激气流中，并且仅依靠正强化来发展和维持辨别反应。测量了三只鸽子对空气中乙酸戊酯的绝对敏感性。所有三只鸽子的阈值在蒸汽饱和度的10（-3.4）至10（-3.6）之间。
