潜伏期操作特性（latency operating characteristic，简称RT-OP）是反应时（reaction time，RT）和辨别准确度之间的权衡关系，被认为是RT任务中对决策策略变化不变性的感知过程的一种度量。根据混淆矩阵计算了RT，混淆矩阵是由RT在给定范围内的试验集构建的。的收敛有效性的支持，速度和准确性之间的强有力的和一致的关系，是不变的刺激和响应概率的变化下的调查结果。几个模型的基本感知过程进行了讨论，导致一个很好的描述，由一组直线的。
The latency operating characteristic (LOG), denned as the trade-off relation between reaction time (RT) and discrimination accuracy, is proposed as a measure of the perceptual process that is invariant over changes in decision strategies in RT tasks. The LOC was computed from confusion matrices constructed from sets of trials on which the RT fell within a given range. The convergent validity of the LOC was supported by findings of a strong and consistent relation between speed and accuracy that was invariant under changes in stimulus and response probability. Several models of the underlying perceptual processes are discussed which lead to a good description of LOC by a set of straight lines.
