Evidence for a visual bias when recalling complex narratives

Abstract

Although it is understood that episodic memories of everyday events involve encoding a wide array of perceptual and non-perceptual information, it is unclear how these distinct types of information are recalled. To address this knowledge gap, we examine how perceptual (visual versus auditory) and non-perceptual details described within a narrative, a proxy for everyday event memories, were retrieved. Based on previous work indicating a bias for visual content, we hypothesized that participants would be most accurate at recalling visually described details and would tend to falsely recall non-visual details with visual descriptors. In Study 1, participants watched videos of a protagonist telling narratives of everyday events under three conditions: with visual, auditory, or audiovisual details. All narratives contained the same non-perceptual content. Participants’ free recall of these narratives under each condition were scored for the type of details recalled (perceptual, non-perceptual) and whether the detail was recalled with gist or verbatim memory. We found that participants were more accurate at gist and verbatim recall for visual perceptual details. This visual bias was also evident when we examined the errors made during recall such that participants tended to incorrectly recall details with visual information, but not with auditory information. Study 2 tested for this pattern of results when the narratives were presented in auditory only format. Results conceptually replicated Study 1 in that there was still a persistent visual bias in what was recollected from the complex narratives. Together, these findings indicate a bias for recruiting visualizable content to construct complex multi-detail memories.

The role of surface and structural similarities in the retrieval of dynamic perceptually rich events.

“…Interestingly, researchers within the field of episodic memory retrieval have found a promising way to experimentally study the determinants of retrieval without sacrificing the dynamic and perceptual nature of the situations processed by the participants (Baldassano et al, 2018;Congleton & Berntsen, 2020;Zacks, 2020;Scheurich et al, 2021). The fact that the perceptual richness of the stimuli was preserved in this research area may not come as a surprise, given the particular interest allocated to the determinant of the so-called "Proustian involuntary memories", whereby sensory / perceptual cues are responsible for triggering a memory (Berntsen, 2007;Mace, 2007).…”
