Contrasts used to characterize tasks effects in our database.

We used CogPO categories for task-related description, and add necessary terms from Cognitive Atlas to describe higher-level cognitive aspect. Here we report only terms that were present in more than one study –aside from the “left foot”, which maps in the analysis as maps in “feet” task category, but not “right foot”. The task categories group terms typically used as conditions and their controls to test a hypothesis. The stimulus modality category stands for CogPO and task categories. Some terms do not belong to any task category and are referred to as such. The arithmetics task category spans across the response modality and instructions CogPO categories.
