Greater BOLD Variability in Older Compared with Younger Adults during Audiovisual Speech Perception

The data for Baum, SH, and Beauchamp, MS. "Greater BOLD Variability in Older Compared with Younger Adults during Audiovisual Speech Perception" (PLOS ONE, in press) can be found here: https://dl.dropboxusercontent.com/u/70081110/BOLDVariabilityData.zip or here http://figshare.com/articles/Greater_BOLD_Variability_in_Older_Compared_with_Younger_Adults_during_Audiovisual_Speech_Perception/1181943

The dataset is organized according to the OpenfMRI organization scheme. Each subject's folder contains the anonymized hi res anatomical images (under the anatomy folder), and the raw .nii files for the localizer scan (BOLD/task001_run001) and task scans (BOLD/task002_run001 and run002). Regressor files in the 3 column FSL format are included for each participant (see paper for details on small differences between scan series in some participants). Information on the demographics of the participants is also included. If you have any questions, please contact Sarah Baum (sarah.h.baum@vanderbilt.edu).

Causal inference of asynchronous audiovisual speech

  1. Experiment 1
  2. Experiment 2

The data are stored as a vector of counts for each subject. Each row is one subject. The trial types are described in the first row. There are 15 levels of asynchrony, 2 levels of visual reliability, and 2 visual intelligibility levels (60 columns in total). Experiment 1 had 12 trials per trial type (3 blocks with 4 trials each) and Experiment 2 had 4 trials (1 block).
