摘　　要：通过2个实验来考察学习判断(Judgment of Learning,JOL)中的练习伴随低估(Underconfidence with Practice,UWP)效应,实验1以21名大学生为被试,考察了延迟JOL中的UWP效应,实验2以36名大学生为被试,考察了项目难度对UWP的影响,结果表明:(1)延迟JOL中没有发现UWP效应;(2)容易项目出现UWP效应,而困难项目中没有出现UWP效应。(3)延迟JOL的相对准确性高于即时JOL,出现延迟判断效应。Two experiments were conducted to explore the underconfidence-with-practice effect（UWP） in judgment of learning（JOL）.Twenty-one undergraduate students were investigated for about the UWP effect in delayed-JOL in experiment one;Thirty-six undergraduate students were investigated for the influence of item difficulty on UWP effect in experiment two.The results show that：（1） there was UWP effect in delayed-JOL codition;（2） UWP effect occured in easy items but not in difficult items;（3） the accuracy of immediate-JOL was lower than that of delayed-JOL,and the delayed-JOL effect occured.There are different results about the effects of practice on the relative accuracy of JOLs.
