A general-purpose variable, used to store experiment parameters, collect results, and mediate the transfer of data between components
Initial value assigned to the variable when the experiment is loaded
Controls the visibility of changes made to the variable’s value.
If a variable has local scope, then changes to its value are visible only within the paradigm component in which the assignment was made. These local changes persist between executions of the paradigm component.
If a variable has global scope, changes to its value are visible everywhere.
Determines when the variable’s value is written to the event stream (and thereby the data file)
YES, then the variable’s value is included in saved variable sets created via MWClient
YES, then the variable’s value is not written to the data file. Other event stream listeners (e.g. MWClient, client- and server-side conduits) continue to receive its value.
Comma-separated list containing the names of groups to which the variable belongs. Variable groups are displayed as expandable sections in MWClient’s variables window.
