Corrected subject-level DCM summaries for NARPS

Corrected within-subject PEB summaries for 48 participants in the openly shared mixed-gambles NARPS data. These summaries replace the preliminary package data used before the first-level input correction.

narps_dcm

Format

A list with:

eta

A 48 by 22 matrix of posterior means.

Cp

A named length-48 list of 22 by 22 posterior covariances.

parameter_names

Names of the 22 parameters.

subject

De-identified participant identifiers.

covariates

Task version, gender, and age for each participant.

regions

Corrected DCM summaries derived from the NARPS data described by Botvinik-Nezer et al. (2020), Nature 582, 84–88. doi:10.1038/s41586-020-2314-9

Details

Each participant has 22 parameters: 16 intrinsic connections from a four-region DCM and six task-modulatory connections. The regions are vmPFC, ventral striatum, amygdala, and anterior insula.
