利用“学习-迁移”的任务范式和单一特征类别判断技术,探讨了分类和推理两种类别学习模式的结果,比较了两种学习模式的效果和策略。研究表明:两种学习模式产生了不同的结果,分类学习的结果是样例,推理学习的结果是原型;在学习效果方面,分类学习比推理学习在达标比例上更高,但在进度上差异不显著;在策略运用方面,分类学习比推理学习更快地使用单维度策略,而在高水平策略的运用上,两者差异不显著。
In this paper, we compare classification learning with another mean of learning categories, inference learning. In inference task, participants predict the value of a missing feature of an item given its category label and other feature values. In the classification task, participants predict the category label of an item given its feature values. Yamauchi and Markman ( 1998, 2000, 2002) showed that these two types of learning do not result in the learning of equivalent knowledge. Categories defined by a family resemblance structure were more easily learned by inference learning than by classification learning, whereas categories defined by a nonlinearly separable structure were more easily learned by classification learning than by inference learning. Chin-Parker and Ross (2002, 2004) found that Classification learners were highly sensitive to diagnostic features but not sensitive to nondiagnostic, but prototypical, features. Inference learners were less sensitive to the diagnostic features than were classification learners and were also sensitive to the nondiagnostic, prototypical, features. The "5 -4" category structure from Medin and Schaffer (1978) has played an important role in the recent dominance of exemplar/instance-based category representation over prototype/centraltendency based representation. Yamauchi and Markman (1998) argued that the type of category representation subjects use, prototypes or exemplars, depends on how they learn the categories, but they did not strongly support this claim with formal models of the representations. This study contrasts the learning results of training subjects on the 5 -4 category structure using either standard classification or feature inference. The research further systematically explores the two learning tasks that might lead to differential learning efficiency, strategy and outcome. Chin-Parker & Ross (2002,2004) pointed out Yamauchi & Markman's two precursory studies that 1998 's ignored irrelative transfer effects and 2002?
