我们提出了一个基于差异测量的阈上感知差异的随机模型。我们开发了一个最大似然差异尺度(MLDS)方法估计其参数和评估的可靠性和分布的鲁棒性的拟合方法。我们还描述了一种方法,用于测试是否差异测量模型是适当的描述人类判断的感知差异,在任何特定的实验环境。
We present a stochastic model of suprathreshold perceptual differences based on difference measurement. We develop a maximum likelihood difference scaling (MLDS) method for estimating its parameters and evaluate the reliability and distributional robustness of the fitting method. We also describe a method for testing whether the difference measurement model is appropriate as a description of human judgment of perceptual differences in any specific experimental context.
