Prefrontal Cortex Responses to Conflicting Information Over time, we form event schemas that guide our expectations, but new related information can require us to re-interpret and update these memories by integrating them into different schemas. In a two....

The effects of beliefs on correcting misinformation in memory We are faced with false information (misinformation) and corrections regularly. Typically, we have no problem correcting misinformation. However, there are individual differences in how effective p...

From one schema to another: How the prefrontal cortex responds to conflicting information Over time, we develop event schemas or scripts that shape our expectations about what typically happens in certain contexts. However, even after forming a memory about a certain event, we are often ex...

Participants actively constructed narratives with systematically manipulated abstract event features to investigate how such abstract event features contribute to updating situation models (2/2)

Of these 3 history-dependent codes, only the schema code correlated (within-participants) with subsequent episodic memory; this provides converging neural support for the idea that schemas act to scaffold memory for unique episodic details. (8/8)

Additionally, we discovered that medial occipital regions code for the preceding ritual in a rotated fashion compared to the current ritual, likely to avoid interference.

We discovered a North-South schema code in the thalamus, pallidum, caudate, posterior medial cortex, hippocampus, parahippocampus, fusiform gyrus, inferior and superior temporal regions, temporal pole, superior frontal regions and a sequence (i.e., path) code in postcentral gyrus. (6/8)

A key feature of the design is that it allowed us to separately measure, on a per-wedding basis, neural codes relating to the North/South schema, specific sequences (paths), the preceding ritual, and the current ritual. (5/8)

Participants had to learn through experience that the transition structure of the ritual sequences was determined by whether the couple was from the North or South of an Island. (4/8)

Participants viewed computer-animated videos of weddings, where the weddings were composed of sequences of made-up rituals. Weddings also included unique episodic details that participants were asked to recall later. (3/8)

In this study, our goal was two-fold: [1] test for various types of history-dependent representation during narrative perception, and [2] look at how these different types of history-dependent representation at encoding relate to subsequent memory for episodic details. (2/8)
