adding a PracticeBlockList, a PracticeMode attribute to track the practice mode, some user-
entered script to score the accuracy, and repeating the practice block if the accuracy criterion is
not met.
2.7.1 Duplicate BlockList in the Browser
We want to have a PracticeBlockList very similar to the BlockList. By duplicating the BlockList we
have a copy that can be modified without affecting the BlockList. In the View menu, select the
Browser option to display the Browser window. In the Browser, select the BlockList object and
right-click to display a context menu. From the context menu, select Copy to make a copy of the
BlockList, and paste the copy (which will be named BlockList1 by default) into the Browser.
Select BlockList1 and right-click to display the context menu once again. Rename BlockList1 to
PracticeBlockList.
The PracticeBlockList object, an exact copy of the BlockList object, will be created in the
Unreferenced E-Objects folder in the Structure view. Open the SessionProc in the Workspace
and drag the PracticeBlockList object to the SessionProc following the Introduction.
2.7.2 Add block level attribute PracticeMode
In order to easily analyze the practice data separately from the main data, add a variable that
codes the information as practice or experimental trials.
2.7.2.1 Modify PracticeBlockList
The PracticeBlockList is an exact copy of the BlockList, so it must be modified to be appropriate
for the practice trials. In the PracticeBlockList, select the first row by clicking on the first row in
the ID column. Click the Remove Levels tool button to delete the selected level.
