The ability to prioritize learning some information over others when that information is considered important or valuable is known as value-directed remembering. In these experiments, we investigate how value influences different aspects of memory, including item memory (memory for the to-be-learned materials) and context memory (memory for peripheral details that occurred when studying items) to get a better understanding of how people prioritize learning information. In this investigation, participants encoded words associated with a range of values (binned into higher, medium, and lower value in Experiment 1, and into higher and lower value in Experiment 2) for a subsequent memory test that measured item memory (Is this item old or new?) as well as both objective context memory (memory for an objectively verifiable contextual detail: In which voice was this item spoken?) and subjective context memory (How many visual, auditory, and extraneous thoughts/feelings can you remember associated with this item?). Results indicated that value influenced item memory but had no effect on objective context memory in both Experiments. In Experiment 2, results showed better subjective context memory for multiple episodic details for higher-value relative to lower-value materials. Overall, these findings suggest that value has a strong influence over some aspects of memory, but not others. This work gives a richer understanding of how people prioritize learning more important over less important information.
当信息被认为是重要或有价值时,优先学习某些信息的能力被称为价值导向记忆。在这些实验中,我们研究了价值如何影响记忆的不同方面,包括项目记忆(对要学习的材料的记忆)和上下文记忆(在学习项目时发生的周边细节的记忆),以更好地了解人们如何优先学习信息。在这项研究中,参与者对一系列具有不同价值的单词进行编码(在实验 1 中分为高、中、低价值,在实验 2 中分为高、低价值),以便在随后的记忆测试中测量项目记忆(这个项目是旧的还是新的?)以及客观上下文记忆(记忆一个可以客观验证的上下文细节:这个项目是用哪种声音说的?)和主观上下文记忆(你能记住与这个项目相关的多少视觉、听觉和无关的想法/感觉?)。结果表明,在两个实验中,价值都影响了项目记忆,但对客观上下文记忆没有影响。在实验 2 中,结果显示,对于更高价值的材料,相对于更低价值的材料,对多个情节细节的主观上下文记忆更好。总的来说,这些发现表明,价值对记忆的某些方面有很强的影响,但对其他方面没有影响。这项工作更深入地了解了人们如何优先学习更重要的信息而不是不重要的信息。
