Autobiographical memories often arise involuntarily, that is, with no preceding retrieval effort, as illustrated by the example. However, most research on autobiographical/episodic memory still works under the assumption that conscious recollections of past events normally require a goal-directed and controlled (voluntary) retrieval process. For example, in his seminal book, Tulving (1983) argued that “access to, or actualization from, the episodic memory system tends to be deliberate and usually requires conscious effort” (p. 46). Mandler (1985) observed that episodic retrieval in general is “deliberate and consciously accessed” (p. 94), while acknowledging that “much of everyday memory experiences are in fact non-deliberate” (pp. 102–103). More recently, Davachi and Dobbins (2008) stated, “Occasionally, a memory will just pop into one’s head wholly uninvited. Although we have all had such involuntary recollections, they are arguably not the norm. . .” (p. 115). Here I am going to challenge this view by arguing that involuntary recollections are a basic mode of remembering.

A basic mode of remembering

On the first pages of his groundbreaking book on memory, Ebbinghaus (1885) identified three basic modes of remembering, a voluntary conscious mode, an involuntary conscious mode, and a non-conscious mode. However, since Ebbinghaus, modern cognitive psychologists have generally ignored the category of involuntary conscious memories (see Berntsen, 2009; Hintzman, 2011, for reviews). In contrast, involuntary conscious memories have received substantial attention in the field of clinical psychology, but almost always in relation to emotionally stressful experiences or psychological disorders (e.g., Brewin, Dalgleish, and Joseph, 1996; Ehlers, Hackmann, and Michael, 2004).
