The idea that memory behavior relies on a gradually-changing internal state has a long history in mathematical psychology. This chapter traces this line of thought from statistical learning theory in the 1950s, through distributed memory models in the latter part of the 20th century and early part of the 21st century through to modern models based on a scale-invariant temporal history. We discuss the neural phenomena consistent with this form of representation and sketch the kinds of cognitive…

A distributed representation of temporal context
TLDR
This work demonstrates that TCM can simultaneously explain recency and contiguity effects across time scales, and provides a principled explanation of the widespread advantage for forward recalls in free and serial recall.
A model for recognition memory: REM—retrieving effectively from memory
A new model of recognition memory is reported. This model is placed within, and introduces, a more elaborate theory that is being developed to predict the phenomena of explicit and implicit, and
Human Episodic Memory Retrieval Is Accompanied by a Neural Contiguity Effect
TLDR
These results constitute the first direct evidence that recovery of an episodic memory in humans is associated with retrieval of a gradually changing state of temporal context, a neural “jump back in time” that parallels the act of remembering.
A Power-Law Model of Psychological Memory Strength in Short- and Long-Term Recognition
TLDR
It is discovered that formal memory-strength parameters from an exemplar-recognition model closely followed a power function of the lag between studied items and a test probe, and alternative models that assumed different functional relations or posited a separate fixed-strength working memory store fared considerably worse than the power-law model in predicting the data.
Compressed timeline of recent experience in monkey lPFC
TLDR
Analysis of single-unit recordings from the macaque lateral prefrontal cortex during performance of a delayed-match-to-category task suggests that working memory is maintained as a compressed timeline, consistent with longstanding cognitive theories of human memory.
Contiguity in episodic memory
TLDR
The broad pattern of data point toward a theory in which contiguity arises from fundamental memory mechanisms that encode and search an approximately time scale invariant representation of temporal distance.
The demise of short-term memory revisited: empirical and computational investigations of recency effects.
TLDR
It is suggested that 2 memory components are needed to account for the recency effects: an episodic contextual system with changing context and an activation-based short-term memory buffer that drives the encoding of item-context associations.
Timing using temporal context
A buffer model of memory encoding and temporal correlations in retrieval.
TLDR
A novel variant of Atkinson and Shiffrin's buffer model within the framework of the retrieving effectively from memory theory (REM) that accounts for findings previously thought to be difficult for such models to explain is described.
From Universal Laws of Cognition to Specific Cognitive Models
TLDR
This article illustrates how principles may be combined to explain specific cognitive processes by using these principles to derive SIMPLE, a formal model of memory for serial order, and briefly mentions some extensions to models of identification and categorization.
