Key Moments Scaffold the Semantic Structure of Narratives

Using spoken recall and annotations from three naturalistic datasets with topic modeling, we ask: which parts of a narrative contribute most to its semantic structure and subsequently memory?

Preprint: osf.io/dcfvw

Excited to share our paper (with @jzacks.bsky.social), now out in JEP:LMC!

Event boundaries sometimes disrupt temporal order memory in list-based paradigms—but what happens in narratives with more complex structures that better resemble real life?

Adaptive episodic memory: how multiple memory representations drive behavior in humans and nonhumans | Physiological Reviews | American Physiological Society Episodic memory is a declarative long-term memory of a specific past experience. As such, it is multifaceted, encompassing both the objective and subjective components of that experience. These components can be flexibly represented at different levels of granularity, from precise, context-specific details to generalized, gistlike representations. In this review, we suggest that 1) multiple representations of an episodic memory at different levels of granularity are simultaneously encoded into a memory trace and 2) the relative weighting of these representations determines the extent to which a memory is reconstructed or reproduced at retrieval. We propose that this representational flexibility drives adaptive behavior by prioritizing reconstruction or reproduction depending on the age of the memory, its relationship to prior knowledge, current attentional goals or task demands, and individual differences. Drawing on research in humans and nonhuman animals, we show a close correspondence between psychological and neural representations of a memory across encoding, consolidation, and retrieval. Specifically, we discuss how hippocampal activity in humans and engram formation and activation in rodents support the reproduction of detailed memory representations, whereas schema formation across species, mediated by the medial prefrontal cortex, facilitates reconstruction and generalization to guide behavior. Finally, we consider how species- and individual-level differences shape episodic memory representations. By integrating findings across species, we illustrate how the correspondence between neural and psychological representations enables multiple memory representations to balance stability and flexibility, ultimately driving adaptive behavior.

How do memories guide behaviour?

Multiple memory representations, from detailed to gist-like, let us flexibly reconstruct or reproduce past experiences to behave adaptively across species.

Hippocampal Drift Rate Reflects the Temporal Organization of Memories When freely recalling past events, individuals tend to successively remember stimuli that were studied close together in time—a phenomenon known as temporal clustering. Temporal clustering is thought ...

How do changes in context influence how we organize our memories in time?

Faster contextual changes are associated with faster drift in hippocampal activity and reduced temporal clustering in recalled memories.

Elegant work led by @lindsayrait.bsky.social!

Temporal dedifferentiation of neural states with age during naturalistic viewing - Communications Biology Movie fMRI data reveals age-related lengthening of neural states in visual and prefrontal regions, reflecting reduced temporal differentiation while preserved alignment with perceived events suggests stable coarse event segmentation.

The brain represents the world around us as a series of neural states - stable patterns of activity that change as we move from one event to the next.

How do the brain’s event representations change as we gain familiarity with an experience?

Brain regions’ representations can become coarser or finer as event familiarity increases. Fine-tuning predicts memory recall.
