Abstract

When learning, it is often necessary to identify important themes to organize key concepts into categories. In value-directed remembering tasks, words are paired with point values to communicate item importance, and participants prioritize high-value words over low-value words, demonstrating selective memory. In the present study, we paired values with words based on category membership to examine whether being selective in this task would lead to a transfer of learning of the "schematic reward structure" of the lists with task experience. Participants studied lists of words paired with numeric values corresponding to the categories the words belonged to and were asked to assign a value to novel exemplars from the studied categories on a final test. In Experiment 1, instructions about the schematic structure of the lists were manipulated between participants to either explicitly inform participants about the list categories or to offer more general instructions about item importance. The presence of a visible value cue during encoding was also manipulated between participants such that participants either studied the words paired with visible value cues or studied them alone. Results revealed a benefit of both explicit schema instructions and visible value cues for learning, and this persisted even after a short delay. In Experiment 2, participants had fewer study trials and received no instructions about the schematic structure of the lists. Results showed that participants could learn the schematic reward structure with fewer study trials, and value cues enhanced adaptation to new themes with task experience.

摘要

在学习过程中,通常需要识别重要主题,将关键概念归类。在有价值导向的记忆任务中,单词与分值配对,以传达项目的重要性,参与者会优先选择高价值单词而不是低价值单词,这表明存在选择性记忆。在本研究中,我们根据类别成员关系将价值与单词配对,以检验在该任务中进行选择是否会导致随着任务经验的增加,对“列表的示意性奖励结构”的学习迁移。参与者学习单词与数值配对的列表,数值对应单词所属的类别,然后在最终测试中要求他们对来自学习类别的新示例进行赋值。在实验 1 中,我们在参与者之间操纵关于列表示意结构的说明,以明确告知参与者列表类别,或提供关于项目重要性的更一般说明。在参与者之间还操纵了编码期间可见值提示的存在,这样参与者可以学习带有可见值提示的单词,或者单独学习它们。结果表明,明确的示意说明和可见的价值提示都对学习有好处,即使在短暂的延迟后也是如此。在实验 2 中,参与者的学习次数减少,并且没有关于列表示意结构的说明。结果表明,参与者可以通过较少的学习次数学习示意性奖励结构,并且价值提示可以增强在任务经验下对新主题的适应能力。
