Gilkey等人[J. Acoust.美国社会78，1207-1219（1985）]在25个可再现噪声样本的每一个中的四个起始相位角的每一个处测量用于检测500-Hz音调的命中比例和虚警比例。在本文中，他们的结果是通过拟合Jeffress [J. Acoust.美国社会48，480-488（1967）]的diotic数据。该模型的最佳拟合配置不对应于能量检测器或包络检测器。由50 Hz宽的单调谐滤波器组成的检测器，然后是半波整流器和积分时间为100至200 ms的积分器，相对较好地拟合了所有四个受试者的数据。中心频率或积分窗口不同的几个检测器的输出的线性组合提供了更好的数据拟合。这些线性组合为某些频率或某些时间间隔分配负权重，表明受试者的决策是基于对刺激的不同光谱或时间部分中的信息的比较。
Gilkey et al. [J. Acoust. Soc. Am. 78, 1207-1219 (1985)] measured hit proportions and false alarm proportions for detecting a 500-Hz tone at each of four starting phase angles in each of 25 reproducible noise samples. In the present paper, their results are modeled by fitting the general form of the electrical analog model of Jeffress [J. Acoust. Soc. Am. 48, 480-488 (1967)] to the diotic data. The best-fitting configurations of this model do not correspond to energy detectors or to envelope detectors. A detector composed of a 50-Hz-wide single-tuned filter, followed by a half-wave rectifier and an integrator with an integration time of 100 to 200 ms fits the data of all four subjects relatively well. Linear combinations of the outputs of several detectors that differ in center frequency or integration window provide even better fits to the data. These linear combinations assign negative weights to some frequencies or to some time intervals, suggesting that a subject's decision is based on a comparison of information in different spectral or temporal portions of the stimulus.
