为了比较各种适应性心理物理程序的有效性和效率，我们开发了一个模拟这些程序的程序，并在三个实验中比较了几种适应性方法：双耳检测、耳间强度识别和耳间时间识别。仿真程序以一个心理测量函数作为输入，该函数指定对任意自适应变量的值作出正确反应的概率。通过根据正在模拟的过程的规则（包括停止和计算阈值估计的规则）选择变量的下一个值来生成阈值。软件生成阈值的分布，并进行统计分析，如所得分布的偏差和方差。该程序已应用于适合于正常听力和听力受损听众的心理测量功能，用于上述三个实验中的每一个，并比较了一些自适应…
In order to compare the efficacy and efficiency of various adaptive psychophysical procedures, a program that simulates these procedures has been developed and used to compare several adaptive methods for three experiments: binaural detection, interaural intensity discrimination, and interaural time discrimination. The simulation program takes as input a psychometric function, which specifies the probability of a correct response for any value of the adapting variable. A threshold is generated by choosing the next value of the variable according to the rules of the procedure being simulated, including the rules for stopping and calculating the threshold estimate. The software generates distributions of thresholds and statistical analyses are performed, such as bias and variance of the obtained distribution. The program has been applied to psychometric functions appropriate for normal‐hearing and hearing‐impaired listeners for each of the three experiments noted above, and has compared a number of adaptive...
