Abstract

The controversy in the relationship between item memory and source memory is a focus of episodic memory. Some studies show the trade-off between item memory and source memory, some show the consistency between them, and others show the independence between them. This review attempts to point out the connection-strength model, implying the different types and strengths of the important role of the item–source connections in the relationship between item memory and source memory, which is based on the same essence in the unified framework. The logic of the model is that when item memory and source memory share the same or relevant connection between item and source, they positively connect, or they are independently or negatively connected. This review integrates empirical evidence from the domains of cognition, cognitive neuroscience, and mathematical modeling to validate our hypothesis.

Highlights

Effective retrieval cues play an important role in memory recovery
We suggested that the different types and different strengths of connections between item and source, item and item, and source and source play an important role in the relationship between item and source memory
Source memory can be divided into two types: intrinsic source memory, which is the features of the item itself, and extrinsic source memory, which is the associated features outside the item, including the context and objects that are associated with the item

Summary

INTRODUCTION

The item always connects with different kinds of information, including semantic information, perceptual information, contextual information (spatial or temporal information), affective information, and operative track. The different experiment designs and “processes” will influence the relationship between the item and source memory, which is based on the same or different connections in the model that we propose These models include the “multinomial processing tree,” “receiver operating characteristic analysis,” “context maintenance and retrieval model,” and “bivariate signal detection model.”. The multidimensional signal detection theory states that recognition memory and source memory depend on the projection of the multidimensional configuration onto an appropriate unidimensional axis, which is deployed as evidence to make memory decisions This explanation is consistent with our strength model, which implies that source memory and recognition share the same or different item–source connections; they are based on the same mechanism. Recognition and source memory use the same memory database that employs different information connections
