The Effect Of Discriminative Contrast And Category Similarity On Metacognitive Monitoring In Category Learning

In the category learning,the study found that the classification results under the presentation of mixed samples from different categories were better than the classification results in the same category of presentation(Kang & Pashler,2012).The researchers believe that the former improves the difference between different categories of samples.Contrast,and this comparison is good for classification results.Studies have also shown that differences can only promote category learning when categories are very similar and indistinguishable.The way in which stimulating materials are presented affects learning outcomes,while the extent to which presentation and subsequent presentation affect learning outcomes is different(Mayer,1995;Gerjers,2009;Sweller,1999).Based on this,this study mainly discusses the effects of different contrast conditions and different categories of similarity on metacognitive judgment and classification performance when presenting and presenting materials.This study consists of four experiments: the experiment is divided into two experiments,a and b,which are all designed in a single factor test,and explore the metacognition of different contrast conditions under the conditions of simultaneous presentation and subsequent presentation of experimental materials.There are differences in monitoring and classification scores,and the independent variables are comparative conditions,which are divided into two levels: contrast and no comparison.The experiment is divided into two experiments a and b,all of which are 4(category similarity: consistent,high,medium,low)× 2(contrast conditions: contrast,no contrast)mixed experimental design,respectively,from simultaneous presentation and subsequent presentation Under the conditions,it is necessary to explore whether the metacognitive judgments and classification scores of different categories of similarity and different contrast conditions are different.The four experiments mainly lead to the following conclusions:(1)The individual's learning judgment on the natural concept category learning is not affected by the difference contrast condition.(2)Only when the category similarity is high,the individual's category learning judgment on the natural concept category learning will be affected by the difference contrast condition.(3)The category learning judgment can predict the classification score more accurately than the learning judgment.(4)Only when the category is highly similar,the individual's classification scores for the natural concept category will be affected by the contrast conditions.
