The task-based fMRI scans require special stimulus presentation and response collection equipment and software. All ABCD fMRI tasks are currently programmed in E-Prime Professional 2.0 versions 126.96.36.1996 or later and work reliably for PC Windows 8.1 or earlier.
The tasks and stimuli are available for download here and are free to be used by others for their own research projects. When referencing these tasks be sure to use the provided citations. By downloading these tools you agree to using them for educational and research purposes only.
