对四组成年人测量了是非任务的反应标准和两个测试程序的检测阈值：年轻听力正常者、老年听力正常者、年轻听力障碍者和老年听力障碍者。 这两个测试程序是听力程序（不控制反应偏差）和 2IFC 自适应程序（控制偏差）。 该信号是安静呈现的 500 或 4000 Hz 音调。 所有四个小组在“是-否”任务中都表现出同样保守的反应偏差。 此外，年龄和听力损失都不会影响两个阈值测量之间的差异（6.5 dB）。
Response criteria from a yes-no task and detection thresholds from two test procedures were measured for four groups of adults: younger normal-hearing, older normal-hearing, younger hearing-impaired, and older hearing-impaired. The two test procedures were an audiological procedure (which does not control for response bias) and a 2IFC adaptive procedure (which does control for bias). The signal was a 500 or 4000 Hz tone presented in quiet. All four groups showed an equally conservative response bias in the yes-no task. In addition, neither age nor hearing loss affected the difference (6.5 dB) between the two threshold measures.
