在心理物理学选择的情况下，Piglitarian辨别刺激持续时间。在呈现一组短持续时间（11至15秒）中的任何持续时间后，对红色键的反应间歇性地得到加强。在呈现一组长持续时间（16至22秒）中的任何持续时间后，对绿色键的反应间歇性地得到加强。相对强化率操纵跨条件的选择反应。由于相对强化率各不相同，心理测量功能显示在所有持续时间的绿键反应的变化。信号检测分析表明，敏感性保持大致恒定的条件，而响应偏差的变化作为一个函数的相对强化率的变化。相对错误率往往与相对强化率相匹配。
Pigeons discriminated stimulus duration in a psychophysical choice situation. Following presentation of any duration from a set of short duration (11 to 15 sec), responses on a red key were reinforced intermittently. Following presentation of any duration from a set of long durations (16 to 22 sec), responses on a green key were reinforced intermittently. Relative reinforcement rates were manipulated for choice responses across conditions. As relative reinforcement rates were varied, psychometric functions showed shifts in green-key responses at all durations. A signal-detection analysis showed that sensitivity remained roughly constant across conditions while response bias changed as a function of changes in relative reinforcement rate. Relative error rates tended to match relative reinforcement rates.
