# Learning Habits

This dataset contains MRI data from 70 participants collected for the Learning Habits study,
led by Hugo Fluhr, Viktor Timokhov, and Stephan Nebe at the Zurich Center for Neuroeconomics,
University of Zurich.

## Study overview

Participants performed a binary choice task during fMRI scanning.
On each trial, participants were shown a pair of stimuli and chose one. They then received feedback about both stimuli (how many points each was worth) during the learning phase. The task was designed to probe the formation of habitual choice behavior across learning.

## MRI acquisition

Scanner: Philips 3T
- Anatomical: T1-weighted (defaced for anonymisation)
- Functional: 3 runs per participant (2 learning runs, 1 test run); TR = 2.33 s, TE = 30 ms,
  40 slices, 3 mm isotropic, 0.5mm gap
- Fieldmaps: phase-magnitude pairs for each functional run

## Dataset structure

- 70 participants, 1 session each (ses-1)
- Tasks: task-learning (run-1, run-2), task-test (run-3)

## Funding

Swiss National Science Foundation grants 207613 and 215002.
