In the work, the psychophysical model of the signal detection theory with the nine outcomes (PMSDT9) for a quantitative description of the solution of the sensory problem of detecting an alternating differential signal was proposed. Unlike the classical model, PMSDT9 has the three probability density functions of the subjective intensity and the sign of the differential signal (instead of the two), the two criteria of displacement (instead of the one), and the nine outcomes (instead of the four). The proposed PMSDT9 model generalizes the application of the classical model of the signal detection theory for the less‐equal‐more task. The modified model provides for the existence of the two criteria (the left and the right) and such outcomes as inversion. The obtained experimental results are consistent with the ideas about the noise in sensory systems.

少等多任务的经典信号检测理论的推广

在工作中，提出了具有九种结果的信号检测理论的心理物理模型（PMSDT9），用于定量描述检测交替差分信号的感觉问题的解决方案。与经典模型不同，PMSDT9具有主观强度和差分信号符号（而不是两个）的三个概率密度函数，位移的两个标准（而不是一个）和九个结果（而不是三个）。四）。所提出的PMSDT9模型将信号检测理论的经典模型的应用推广到少等多任务。修改后的模型提供了两个条件（左和右）的存在以及诸如反演的结果。
