Memory and Consciousness—Usually in Tandem but Sometimes Apart

Abstract

Episodic memory, the ability to remember specific events from one's personal past, has been the subject of research for several decades, with a particular emphasis on its relationship with consciousness. In the December 2022 issue of Cognitive and Behavioral Neurology, Budson, Richman, and Kensinger shed new light on this complex topic with a comprehensive exploration of consciousness. In this commentary, I present three propositions about the relationship between episodic memory and consciousness: (1) Episodic memory is usually associated with conscious retrieval; (2) it is possible to have consciousness without episodic memory; and (3) episodic memory can be accessed without conscious retrieval. Drawing from studies conducted with nonhuman animals, I provide evidence to support each of these propositions and discuss how they relate to the theory presented by Budson et al (2000). Although some of my propositions differ from their views, their work has been valuable in stimulating ongoing discussions to advance our understanding of memory.

Memory Can Define Individual Beliefs and Identity—and Shape Society

“…As we gather experiences, we develop decision-making heuristics that guide our choices in various situations (Madan et al, 2021;Mason et al, 2022;Weber & Johnson, 2006). These heuristics are shaped not only by direct memories of past events but also by experiences that influence our beliefs and behaviors, even if we are not consciously able to recollect them (Addis & Tippett, 2004;Guzmán-Vélez et al, 2014;Kunst-Wilson & Zajonc, 1980;Madan, 2020Madan, , 2023Palombo et al, 2021).…”
