Misinformation false memory fMRI (ds004261)
Cross-stage neural pattern similarity in the hippocampus predicts false memory derived from post-event inaccurate information
Task fMRI and T1-weighted brain MRI of 57 healthy Chinese college students who viewed picture stories, later read narratives with misleading details and took a memory test the next day, to study how misinformation creates false memory. Released in BIDS under CC0.
Overview
This OpenNeuro release holds the fMRI experiment of a Beijing Normal University study of the misinformation effect by Xuhao Shao, Bi Zhu, Elizabeth Loftus and colleagues. Participants first viewed eight picture stories of incidents such as a street theft, three hours later read narratives about the same stories in which some details were described wrongly, and the next morning answered a recognition test. The study tracks how hippocampal and cortical activity patterns carry over between these three stages and which of them predict a false or a true memory. Data are in BIDS under CC0, with the analysis code bundled as a zip file.
Composition
57 healthy, right-handed Chinese college students, all in the misinformation condition. The paper reports 29 women and 28 men with a mean age of 22 years. Each subject has three sessions (day1AM original event, day1PM post-event information, day2AM memory test), each with four BOLD runs and a fieldmap. The T1-weighted image is stored in the day1PM session. The participants table gives age, sex and group.
Acquisition
All scans were made on a Siemens Prisma 3 T scanner with a 64-channel head-neck coil at the Beijing Normal University MRI Center. Functional runs use a simultaneous multi-slice EPI with TR 2000 ms, TE 34 ms, 2 mm isotropic voxels, 72 slices and multiband factor 3. The structural image is a 1 mm MPRAGE (TR 2530 ms, TE 2.27 ms). A dual-echo gradient echo fieldmap was recorded for distortion correction.
Annotations
There are no image labels. Event files give onsets, item ids and versions, trial types and, for the memory test, the response, reaction time and response type.
Known limitations
- participants.tsv lists 30 women and 27 men, while the paper reports 29 and 28; the paper's mean age (22) is rounded, the table gives 21.5.
- sub-2063 has no T1-weighted image.
- sub-2035 has two fieldmaps in the day1PM session.
- The two behavioural-only groups of the paper (neutral and consistent information) were not scanned.
- Single site, narrow age range; dataset_description.json still holds template placeholders.
