2.3.3 Perform Step 1.3: Specify the core experimental
design
2.3.3.1 Create and name the List object
The independent variables, stimuli, and expected responses are generally specified on a List
object. Drag a List object from the Toolbox to the SessionProc timeline. Rename the List1
object to DesignList by clicking on List1, pressing the F2 key (to enter Edit mode) and typing in a
new name for the object. The Structure view appears as the following:
2.3.3.2 Add the attributes for the design
Recall from the abstract that we wanted to implement the following condition table:
Condition Stimulus Correct Response
Word cat 1
NonWord jop 2
To do so, first open the DesignList object (double click on it in the Structure view). Then, click
the Add Multiple Attributes button. Specify that there are 3 attributes to add. Double click each
column header to change the attribute names for Attribute1, Attribute2, and Attribute3 to
Condition, Stimulus and CorrectResponse respectively (Note, no spaces are permitted in the
attribute name).
2.3.3.3 Add the needed rows and fill in the attributes for the
experiment
Implement the simplest version that illustrates the varying aspects of the experiment. This will
require having 2 rows (for Word and Non-Word). Click the Add Level tool button to add one row.
Then fill in the values for the levels of the attributes. Enter the values of the Condition, Stimulus,
and CorrectResponse attributes for two trials as shown in the next figure.
