The data consist of two task: The ToM localizer task and the RPS task. Data were acquired in a single scanning session using a 3T Philips Achieva scanner. 176 T2*-weighted standard echo planar imaging (EPI) volumes were obtained in each of the RPS task runs, using a 32 channel head coil. Parameters used to achieve whole brain coverage are as follows: TR=2.5s, TE=35ms, acquisition matrix = 80 x 80, flip angle =83°, isotropic voxels 3x3x3 mm3, 42 slices axial acquisition obtained consecutively in a bottom-up sequence. Using the same parameters, 71 EPI volumes were acquired for each run of the localizer task. A T1-weighted scan was then acquired as a single volume at higher spatial resolution as a 3D TFE image (matrix size 288x288, 175 slices, sagittally acquired and reconstructed to 1x1x1 mm3 isotropic voxels. TE =3.8ms. TR = 8.4 ms).
Preprocessing and statistical analyses of the data were performed using the FMRIB software library (FSL version v.5.0.6; FMRIB, Oxford, www.fmrib.ox.ac.uk/fsl). For both experiments, initial preprocessing of the functional data consisted of slice timing correction, and motion correction (MCFLIRT). The blood oxygen level dependent (BOLD) signals were high-pass filtered using a Gaussian weighted filter to remove low-frequency drifts in the bold signal. Spatial smoothing of the BOLD signal was performed using a 5mm full-width-half-maximum kernel. The functional data were registered to their respective structural images and transformed to a standard template based on the Montreal Neurological Institute (MNI) reference brain, using a 6-DoF linear transformation (FLIRT).
The data consist of two clearly labeled folders one containing the data for the ToM localizer task, and one for the RPS tasks. Specific questions about the data can be directed to corresponding authors.
