Using signal detection theory, we investigated whether human participants represent time linearly or logarithmically in a bisection task. Participants saw a stimulus 1.0 to 1.5 s in duration, and then judged whether the stimulus duration was closer to 1.0 s or to 1.5 s, and how sure they were of their response. Whereas the mean of the subjective stimulus duration was a linear function of the objective stimulus duration, participants produced remarkably different psychophysical functions-linear for some participants, concave for others, and convex for still others. Hence, the appropriate question might not be whether humans encode time linearly or logarithmically, but for which participants and under which conditions is time encoded linearly, logarithmically, or even exponentially.

运用信号检测理论，我们研究了人类参与者在二分任务中对时间的表征是呈线性还是对数形式。参与者观看持续时间为1.0至1.5秒的刺激，然后判断刺激持续时间更接近1.0秒还是1.5秒，以及他们对自己的回答有多确定。虽然主观刺激持续时间的平均值是客观刺激持续时间的线性函数，但参与者产生了显著不同的心理物理函数——一些参与者呈线性，另一些呈凹形，还有一些呈凸形。因此，恰当的问题可能不是人类是否以线性或对数形式编码时间，而是对于哪些参与者以及在哪些条件下时间是以线性、对数形式甚至指数形式编码的。（《心理学文摘数据库记录》（c）2018美国心理学会，保留所有权利）
