Each of the SlideState objects shows an asterisk in one of the possible positions. Each has a
unique name, and is listed as level in the StateName attribute in the TrialList. In the Property
pages for the Slide object, the Slide calls one of the four SlideState objects via its ActiveState
property. The ActiveState property determines which SlideState will be presented on each trial.
The Stimulus attribute determines the image to be displayed on each trial (i.e., the arrow
direction). The CorrectAnswer attribute (“1” or “2”) is used to score the input collected in
response to the Stimulus display, and provide feedback via the Feedback object.
Sub-objects are entered on a Slide using the SlideText and SlideImage tool buttons. Click the
appropriate sub-object tool button and click the Slide grid area to create the sub-object.
Each Slide state and sub-object maintains its own property settings. The settings may be
accessed by selecting the appropriate state or sub-object from the drop-down menu on the Slide,
and clicking the Properties button (Figure 1). In the properties for the sub-object selected in the
image below, the value of the Up attribute is resolved at run-time by referring to the TrialList
object. The value of the Up attribute will either be an asterisk (*) or nothing (i.e., will be blank).
The BackStyle property for this sub-object is set to transparent so that drawing time is minimized
(Figure 2).
