Datasets are provided by the University of Illinois at Urbana-Champaign (UIUC) via funding provided by the Intelligence Advanced Research Projects Activity (IARPA) under the Strengthening Human Adaptive Reasoning and Problem-solving (SHARP) program.  Please complete the form below to request access to the datasets.

Study Design

The provided data comes from a broader intervention-based longitudinal study, designed to test the efficacy of interventions designed to enhance fluid intelligence. This specific intervention involved 48 training sessions of an adaptive visuo-spatial and change detection task. We provided both behavioral measures and neuroimaging data at both pre-intervention and post-intervention.  We also provided summary and session-level descriptions of the training data collected during the intervention.

Behavior

We provided pre- and post-test measures of two standardized tests of fluid intelligence:  Figure Series, and the analogical reasoning portion of the Law School Admissions Test. For both tests, we provided item level accuracy (coded as 1=correct, 0=incorrect) and reaction time (seconds).  Behavioral measures at each timepoint are provided in a *.csv file, where the 25 rows represent participants and the 25 columns (for LSAT) or 30 columns (for Figure Series) represent test items.  We also included three measures of processing speed: Letter Comparison, Pattern Comparison, and the Digit Symbol Substitution Task. We also included basic demographics, such as age, sex and years of education.

Training

We provided intervention training data from three versions each of a Visuospatial and Change Detection task. These data are provided in a *.csv file, containing the average difficulty level across 48 training sessions for each version of the tasks.

Brain Imaging

We provided three types of neuroimaging data for each participant.  First, we provided the structural T1 scan, a high-resolution image of the brain. Each *.nii.gz file is about 13MB in size, with a 0.9mm resolution.  Second, we provided functional neuroimaging data acquired at rest.  Resting state data are provided in the form of a processed functional connectome, a *.csv format file containing pairwise functional connectivity values from 256 cortical regions. We also provided the pre-processed and filtered resting state scans in *.nii.gz files, about 350MB in size each. Finally, we provided probabilistic tensor and tractography data from a Diffusion Tensor Imaging (DTI) scan.  For each subject, we provided *.csv files describing the probabilistic fiber paths of white-matter structural connectomes between 68 cortical regions. We also provided *.nii.gz files, about 1MB in size each, containing probabilistic tensor components describing anisotropic diffusion in the brain. All files are provided at pre- and post-intervention.

The full dataset is 11.29GB. The dataset can be downloaded in full, or in more manageable chunks separated as:

• Behavioral and analyzed fMRI/DTI data
• Structural T1 images
• Raw resting-state fMRI data (divided in 5 file groups)
• Raw DTI data

NEW STANDALONE FILE UPLOADED ON NOV 8, 2017 (TestingDataAllSubs.csv) - This spreadsheet summarizes the educational attainment and behavior data for each subject. The education level is identified as follows:  'No high school', '1', 'Some high school', '2', 'High school graduate', '3','Some college', '4', 'College graduate', '5', 'Some post-graduate', '6', 'Master''s degree or higher', '7' .

TERMS OF USE:

Participants must use the data, and any solution derived from the data solely for the purpose and duration of the Competition, including but not limited to privately sharing data outside of teams or for publication, unless provided express permission by UIUC and the IEEE Brain Initiative. If permission is granted to publish or release data in any capacity, acknowledgment must be given to UIUC and the IEEE Brain Initiative in terms provided by them.
