EX (Execute Expression)

The EX trial command executes an expression block and updates all variables as defined in the expression definition.

If this variable is later used as an argument of a trial command, or as variable content of a picture definition, then the new value set by the EX command will be used.

Use this trial command to compute and use dynamic settings during the execution of the experiment depending on the participant’s performance.
