摘要: 本研究采用3个实验考察编码强度对字体大小效应的影响, 探讨由于知觉特征而引发的元认知错觉的内在产生机制(实验1)与有效的矫正措施(实验2和实验3)。结果发现:(1)大字体词语的知觉流畅性显著优于小字体, 并且贝叶斯多层中介分析结果表明, 知觉流畅性对字体大小效应起部分中介作用(实验1); (2)随着编码强度的增加, 由字体大小引起的学习判断错觉逐渐消失(实验2和实验3)。以上结果表明, 刺激的知觉特征(字体大小)对个体学习判断的影响, 随编码强度激活线索的增加而逐渐减弱。这一结果为真实教学情境中提高学习者的编码强度, 进而削弱学习判断对知觉特征线索的依赖, 并准确地监测自身的学习进程提供了科学依据。
