Monitoring one's knowledge during study is susceptible to a foresight bias (Koriat and Bjork, 2005). Judgments of learning (JOLs) are inflated whenever information that is present at study and absent, but solicited, at test, such as the targets in cue-target paired associates, highlights aspects of cues that are less apparent when those cues are presented alone. The present findings demonstrate that foresight bias can be alleviated by study-test experience (Experiment 1), particularly test experience (Experiments 2 and 3), and by delaying JOLs after study (Experiment 4) and that both foresight bias and its alleviation have behavioral consequences, as measured by study time allocation (Experiment 5). Collectively, the findings suggest that overconfidence and misallocation of study time arise from a mismatch that is inherent to education--that the answer is present at study and absent at test--and that alleviating the problem requires creating conditions at study that sensitize learners to retrieval conditions at test.
在学习过程中监测自己的知识容易受到先见偏差的影响(科里亚和比约克,2005年)。每当学习时出现但测试时未出现但被要求的信息(例如线索-目标配对联想中的目标)突出了线索单独呈现时不太明显的方面时,学习判断(JOLs)就会被夸大。目前的研究结果表明,先见偏差可以通过学习-测试经验(实验1),特别是测试经验(实验2和3),以及在学习后延迟JOLs(实验4)来减轻,并且先见偏差及其减轻都有行为后果,如通过学习时间分配来衡量(实验5)。总体而言,这些发现表明,过度自信和学习时间的错误分配源于教育中固有的不匹配——答案在学习时存在而在测试时不存在——并且减轻这个问题需要在学习时创造条件,使学习者对测试时的检索条件敏感。
