How are memories transformed over time to enable anticipation of the future?

With consolidation, multistep anticipation becomes more efficient but less perceptually detailed.

Proud of Hannah Tarder-Stoll for leading this collaboration w/ @ChrisBaldassano!

EDITED: For those who haven't heard Mariam Aly of Columbia Psychology announced that she would not be promoted to Associate Professor w/o tenure, and she would not be put up for tenure. See her tweet:
Today I learned that
@Columbia
will not be promoting me or putting me up for tenure. I have multiple active grants (including an R01 and a CAREER award) plenty of publications, a teaching award, and a history of DEI advocacy. Open to all opportunities in and out of academia.

We can think of decision points in navigation like event boundaries--points of uncertainty when you want to rapidly form highly pattern separated, context dependent memories https://t.co/noSLevZ2ci

A neural network model of when to retrieve and encode episodic memories

A neural network showed better prediction of upcoming states when it was selective in when it encoded and retrieved episodic memories, thereby explaining why humans show this selectivity in studies of naturalistic memory.

I'm so happy to see
this paper from Jordan Crivelli-Decker's dissertation finally out!
Our results go in the opposite direction of the "vanilla" successor representation. Modeling suggests that people selectively encode the relevant information at decision point (i.e., event boundary) and deploy these memories during navigation. https://t.co/Ia37PXwctl
Goal-oriented representations in the human hippocampus during planning and navigation - Nature Communications

Several lines of evidence suggest the hippocampus plays a key role in navigation. Here, the authors show that during navigation hippocampal patterns represent context-specific, goal-oriented information.
