New from our lab: your brain doesn’t just remember time - it bends it.

We show that the dopamine system responds to natural breakpoints in experience, and this relates to more stretched memories of time. Blinking also increases, signaling encoding of new memories.

www.biorxiv.org/content/10.1...

Dopaminergic processes predict temporal distortions in event memory

Our memories do not simply keep time - they warp it, bending the past to fit the structure of our experiences. For example, people tend to remember items as occurring farther apart in time if they spa...

Why do we not remember being a baby? One idea is that the hippocampus, which is essential for episodic memory in adults, is too immature to form individual memories in infancy. We tested this using awake infant fMRI, new in @science.org #ScienceResearch www.science.org/doi/10.1126/...

Why do we remember so many details of our experiences even when it is unclear if we will actually ever need them?

In a new preprint, @marcelomattar.bsky.social and I asked whether this property is adaptive, because what will be relevant in the future often (usually?!) isn’t apparent.

Episodic memory facilitates flexible decision making via access to detailed events

Our experiences contain countless details that may be important in the future, yet we rarely know which will matter and which won't. This uncertainty poses a difficult challenge for adaptive decision ...

Our findings suggest that differences in the dynamics of learning can account for age-related changes in structured knowledge acquisition.

Lots more details (and exciting open questions) in the paper!

Kate Nussenbaum @katenuss.bsky.social · Mar 6

The extent to which participants used this more complex form of predictive learning related to — and accounted for age-related improvements in — their explicit knowledge of the task’s underlying structure.

Kate Nussenbaum @katenuss.bsky.social · Mar 6

With increasing age, however, participants engaged a more complex form of state-conditional predictive learning, in which they incrementally constructed an abstracted world model of the temporal relations between states — or, a ‘successor representation’.

Kate Nussenbaum @katenuss.bsky.social · Mar 6

By leveraging a recently developed computational model (www.biorxiv.org/content/10.1...), we found that younger participants primarily engaged in recency-based prediction, such that their expectations for upcoming events are shaped by those they experienced in the recent past.

Trial-by-trial learning of successor representations in human behavior

Here, we show that these developmental differences in explicit knowledge may arise because the predictive learning mechanisms that people engage to make sense of streams of continuous input change from childhood to adulthood.

Kate Nussenbaum @katenuss.bsky.social · Mar 6

While people are excellent statistical learners from early in life, in complex environments, adults sometimes demonstrate greater explicit knowledge of structured relations between states.
