摘　　要：混合效应模型(Mixed-Effects Model,MEM)将被试和刺激项目同时作为随机变量,有效地分析实验效应和相关的被试(或刺激项目)差异,从而避免了传统方差分析的随机效应固定化问题。基于此,文中构建了混合MEM、独立MEM和速度MEM三个联合模型,并与反应和反应时数据的分开建模(即分开MEM)进行比较。在IAT实验数据分析中,分开MEM的模型拟合与参数估计均不如独立MEM,而混合MEM的模型拟合优于独立MEM和速度MEM。模拟结果显示,分开MEM参数估计的相对偏差普遍大于独立MEM,且具有较高的第I类错误率;而混合MEM比其他联合模型能更好地识别不同模拟情景的参数,并且具有较佳的第I类错误率和统计检验力。因此,在心理实验中,联合建模方法比分开建模具有更大优势。Mixed-Effects Models(MEMs)have become a prominent trend in the analysis of psychological experiment data.MEMs can simultaneously treat both subjects and stimuli as random variables,effectively analyzing experimental effects and the associated differences between subjects(or stimuli).This approach avoids the issue of treating subjects or stimuli as fixed variables and consequently the high incidence of false positives,which is common in analysis of variance(ANOVA).Typically,in psychological experiments,reaction and reaction times are described and modeled separately.However,this separation hinders the full utilization and integration of different data from subjects to exploit maximum information from sample datasets.Current psychometric and cognitive process models attempt to jointly analyze different data sources,providing insights for the joint modeling of psychological experiment data.In psychological experiments,a specific duration is typically set for each stimulus,and subjects are required to make a keystroke response within this period.This setup is similar to time-limited tests,but the tasks in psychological experiments are usually simpler.Based on this,the paper constructs three joint models:mixed MEM,independent MEM,and speed MEM.These models are compared with the separate model of reaction and reaction time data(i.e.,separate MEM)in a series of studies.In the analysis of IAT(Implicit Association Test)experiment data,the separate MEM was found to be inferior to the independent MEM in both data fitting and parameter estimation.The mixed MEM showed better model fit indices than both independent MEM and speed MEM.In the simulation studies,different comparisons were conducted using mixed MEM and speed MEM as benchmark models.The simulation results show that the relative bias in parameter estimation for separate MEM was generally greater than that for independent MEM,and it had a higher Type I error rate.Among the joint models,the independent MEM exhibited significant parameter estimate biases across benchmar
