Abstract

Some people exhibit impressive memory for a wide array of semantic knowledge. What makes these trivia experts better able to learn and retain novel facts? We hypothesized that new semantic knowledge may be more strongly linked to its episodic context in trivia experts. We designed a novel online task in which 132 participants varying in trivia expertise encoded "exhibits" of naturalistic facts with related photos in one of two "museums." Afterward, participants were tested on cued recall of facts and recognition of the associated photo and museum. Greater trivia expertise predicted higher cued recall for novel facts. Critically, trivia experts but not non-experts showed superior fact recall when they remembered both features (photo and museum) of the encoding context. These findings illustrate enhanced links between episodic memory and new semantic learning in trivia experts, and show the value of studying trivia experts as a special population that can shed light on the mechanisms of memory.

1000美元的外显-语义联系:琐事专家的新语义知识与外显记忆的结合更紧密。
有些人对大量语义知识的记忆力令人印象深刻。是什么让这些琐事专家能够更好地学习和保留新事实呢?我们假设,在琐事专家身上,新的语义知识可能与其情节背景有更紧密的联系。我们设计了一个新颖的在线任务,让 132 名琐事专长不同的参与者在两个 "博物馆 "中选择一个,对自然事实的 "展品 "和相关照片进行编码。之后,我们测试了参与者对事实的提示性回忆以及对相关照片和博物馆的识别能力。琐事专业知识越强,对新事实的提示回忆能力就越强。重要的是,当琐事专家(而非专家)记住编码情境的两个特征(照片和博物馆)时,他们的事实回忆能力更强。这些研究结果表明,琐事专家的外显记忆和新语义学习之间的联系得到了加强,并显示了将琐事专家作为特殊人群进行研究的价值,可以揭示记忆的机制。

期刊介绍: The journal provides coverage spanning a broad spectrum of topics in all areas of experimental psychology. The journal is primarily dedicated to the publication of theory and review articles and brief reports of outstanding experimental work. Areas of coverage include cognitive psychology broadly construed, including but not limited to action, perception, & attention, language, learning & memory, reasoning & decision making, and social cognition. We welcome submissions that approach these issues from a variety of perspectives such as behavioral measurements, comparative psychology, development, evolutionary psychology, genetics, neuroscience, and quantitative/computational modeling. We particularly encourage integrative research that crosses traditional content and methodological boundaries.
