ABSTRACT

In this study, we use a novel, implicit memory paradigm to test forhyper-binding, or older adults’ tendency to form non-target associations. Participants viewed pictures of objects superimposed with text and made speeded categorization judgments about the objects across three blocks varying in binding demand. During the no- and some-binding blocks, participants decided if the pictured object alone could fit inside a drawer while ignoring superimposed non-words and words, respectively. During the full-binding block, participants decided if both items could fit inside a drawer together. At test, participants viewed intact and rearranged pairs from encoding and decided if both items could fit in a drawer together. Across two experiments, older adults responded faster to intact than rearranged pairs from both the some- and full-binding blocks, while young adults showed no difference in RTs. These findings suggest that implicit associative memory is preserved with age and extends to non-target information.

摘要

在这项研究中，我们使用一种新颖的内隐记忆范式来测试超绑定，或老年人形成非目标关联的倾向。参与者查看叠加有文本的对象图片，并在绑定需求不同的三个区块中对对象进行快速分类判断。在无约束力和有约束力的块中，参与者决定单独的图片对象是否可以放入抽屉，同时分别忽略叠加的非单词和单词。在完整装订块中，参与者决定两个物品是否可以一起放在抽屉里。在测试中，参与者通过编码查看完整和重新排列的对，并决定两个项目是否可以一起放入抽屉。在两个实验中，老年人对来自部分和完全结合块的完整配对的反应比重新排列的配对更快，而年轻人在 RT 上没有表现出差异。
