Abstract

Assessing the time course under which underlying memory representations can be formed is an important question for understanding memory. Several studies assessing item memory have shown that gist representations of items are laid out more rapidly than verbatim representations. However, for associations among items/components, which form the core of episodic memory, it is unclear whether gist representations form more quickly than, or at least in parallel with, verbatim representations, as fuzzy-trace theory predicts, or whether gist is extracted more slowly from inferring the meaning of verbatim representations, as in gist macroprocessor theories. To test these contrasting possibilities, we used a novel associative recognition task in which participants studied face-scene pairs for .75, 1.5, or 4 seconds each, and were later tested on their ability to discriminate intact pairs from foils which varied in how similar they were to originally studied pairs. Across 2 experiments, we found that verbatim memory for associations, measured using a multinomial-processing-tree model, improved from .75 to 1.5 to 4 seconds of presentation time. Paralleling these effects of encoding time on verbatim memory, for gist memory, there were improvements from .75 seconds to 1.5 seconds in both experiment 1 and 2, while improvements from 1.5 seconds to 4 seconds were only evident when the retention interval between study and test was increased (experiment 2). These results provide strong support for the parallel processing framework of fuzzy-trace theory over the slow gist extraction framework of an alternative gist macroprocessor theory.

摘要

评估潜在记忆表现形式形成的时间进程对于理解记忆是一个重要的问题。几项关于项目记忆的研究表明,项目的概要表示比逐字表示更快地呈现。然而,对于构成情节记忆核心的项目/组件之间的关联,尚不清楚概要表示是否比逐字表示更快形成,或者至少与模糊痕迹理论预测的那样平行形成,或者是否从推断逐字表示的意义中提取概要表示更慢,就像概要宏观处理器理论那样。为了检验这些相互矛盾的可能性,我们使用了一种新颖的联想识别任务,参与者研究了人脸-场景对,每个对的呈现时间为 0.75、1.5 或 4 秒,然后测试他们区分完整对和与原始研究对相似程度不同的干扰对的能力。在 2 项实验中,我们发现使用多项处理树模型测量的关联的逐字记忆,从 0.75 秒到 1.5 秒到 4 秒的呈现时间有所提高。与逐字记忆的这些编码时间效应平行,在实验 1 和实验 2 中,概要记忆从 0.75 秒提高到 1.5 秒,而从 1.5 秒提高到 4 秒仅在研究和测试之间的保留间隔增加时才明显(实验 2)。这些结果强烈支持模糊痕迹理论的平行处理框架,而不是替代概要宏观处理器理论的缓慢概要提取框架。(PsycInfo 数据库记录(c)2023 APA,保留所有权利)。
