Episodic memory endows agents with numerous general cognitive capabilities, such as action modeling and virtual sensing. However, for long lived agents, there are numerous unexplored computational challenges in supporting useful episodic memory functions while maintaining real time reactivity. In this paper, we review the implementation of episodic memory in Soar and present an expansive evalua...

Episodic memory is central to the human experience. In typically developing children, episodic memory improves rapidly during middle childhood. While the developmental cognitive neuroscience of episodic memory remains largely uncharted, recent research has begun to provide important insights. It has long been assumed that hippocampus-dependent binding mechanisms are in place by early childhood,...

Humans are able to transcend the present and mentally travel to another time, place, or perspective. Mentally projecting ourselves backwards (i.e., episodic memory) or forwards (i.e., episodic foresight) in time are crucial characteristics of the human memory system. Indeed, over the past few years, episodic memory has been argued to be involved both in our capacity to retrieve our personal pas...

Evidence indicates that episodic memory plays an important role in general cognition. A modest body of research exists for creating artificial episodic memory systems. To date, research has focused on exploring their benefits. As a result, existing episodic memory systems rely on a small, relevant memory cue for effective memory retrieval. We present Ziggurat, a domain-independent episodic memo...

Episodic memory is impaired in multiple sclerosis (MS) patients, possibly because of deficits in working memory (WM) functioning. If so, WM alterations should necessarily be found in patients with episodic memory deficits, but this has not yet been demonstrated. In this study we aimed at determining whether episodic memory deficits in relapsing-remitting MS are found in conjunction with impaire...

For a human, episodic memory is a memory of past experiences that one gains over a lifetime. While episodic memory appears critical to human function, researchers have done little to explore the potential benefits for an artificially intelligent agent. In this research, we have added a task-independent, episodic memory to a cognitive architecture. To frame the research, we propose that episodic...
