我们提出了一个神经认知模型的长期对象的记忆。我们认为知觉启动和情景再认是基于三种不同表征的现象。我们将这些表示标记为类型和标记。类型是对象标识所需的原型表示。在重复识别的过程中，物体分类所需的非任意特征网络变得尖锐，这种效应我们称之为类型痕迹，并导致知觉启动。另一方面，令牌支持情景识别。边缘结构被提出来将内在的对象内特征绑定到对象令牌中，该对象令牌可以被认为是一个合并的感知对象文件。海马结构将对象信息与上下文信息整合在一个情节标记中。假设对象标记的恢复产生熟悉感，而回忆发生在情景标记的恢复发生时。检索模式和检索方向动态调节访问这些表示。在这篇综述中，我们将该模型应用于最近的实证研究（行为，功能磁共振成像和ERP数据），包括我们自己的实验室的一系列研究。我们特别强调了感觉特征及其学习测试匹配对熟悉性的影响。类型标记方法适合数据，并为分析单元化和关联恢复等概念提供了一个框架。
We present a neurocognitive model of long-term object memory. We propose that perceptual priming and episodic recognition are phenomena based on three distinct kinds of representations. We label these representations types and tokens. Types are prototypical representations needed for object identification. The network of non-arbitrary features necessary for object categorization is sharpened in the course of repeated identification, an effect that we call type trace and which causes perceptual priming. Tokens, on the other hand, support episodic recognition. Perirhinal structures are proposed to bind intrinsic within-object features into an object token that can be thought of as a consolidated perceptual object file. Hippocampal structures integrate object- with contextual information in an episodic token. The reinstatement of an object token is assumed to generate a feeling of familiarity, whereas recollection occurs when the reinstatement of an episodic token occurs. Retrieval mode and retrieval orientation dynamically modulate access to these representations. In this review, we apply the model to recent empirical research (behavioral, fMRI, and ERP data) including a series of studies from our own lab. We put specific emphasis on the effects that sensory features and their study–test match have on familiarity. The type–token approach fits the data and additionally provides a framework for the analysis of concepts like unitization and associative reinstatement.
