已经提出了各种心理测量程序，以衡量受试者的心理测量功能的观点阈值。 。在计算机模拟中，对其在已知真理的情况下进行大量样本量的性能进行了评估。
Various psychometric procedures have been proposed to measure perceptual thresholds as points on a subject’s psychometric function. Adaptive procedures are generally preferred due to their precision and efficiency. However, different approaches exist with respect to the stimulus adaptation rule and the final estimation of the resulting threshold. In the presented study, the performance of maximum likelihood methods (Best PEST and ZEST) is compared to traditional adaptive methods (Staircase und PEST). All methods are examined with different paradigms of stimulus presentation (Yes/No, 2AFC, 3AFC). The procedures are evaluated in computer simulations with regard to their performance over a large sample size in the case of known truth. Bias, accuracy and efficiency of each method are analysed. The obtained results provide criteria for selecting an appropriate method for a particular application.
