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 21FC 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.
年轻听力正常者、年长听力正常者、年轻听力受损者和年长听力受损者。这两种测试程序分别是一种听力测试程序（不控制反应偏差）和一种21FC自适应程序（控制偏差）。信号是在安静环境中呈现的500或4000赫兹纯音。所有四组在二选一任务中都表现出同样保守的反应偏差。此外，年龄和听力损失均未影响两种阈值测量之间的差异（6.5分贝）。
