Provides a comprehensive system for composing stimuli and managing stimulus sets. The stimulus management screen (Figure 1) contains the following segments:
Click on the stimulus set drop-down list (Figure 2) and select Create new set...
.
Click on the stimulus set drop-down list (Figure 2) and select Copy an existing set...
.
Click on the stimulus set drop-down list (Figure 2) and select Import from library...
.
Click on the stimulus set drop-down list (Figure 2) and select your desired set from Existing sets
. You will now be in the stimulus set root (Figure 3).
In stimulus set root (Figure 3), click Delete stimulus set
WARNING: Deleting the stimulus set will also remove:
The stimulus set tree (Figure 1:4) provides a hierarchical view of your stimulus set and is comprised of:
Items can be navigated by selection and rearranged by drag and drop. You can also collapse and expand branches by clicking and
respectively.
The view panel is where all your work is done. Select an item in the stimulus set tree (Figure 1:4) to work on that item.
Presents the logical design of the stimulus set. Click Preview stimuli... to run a deep analysis on the composition of your stimulus set. Where problems are discovered, they're reported and fixes proposed. Component group blending and composition strategies will be used in the creation of stimuli for preview.
Stimulus selection strategy (i.e. the order of stimuli selected for presentation) is determined by settings in your trials timeline and is not reflected in the preview. Stimulus variable resolution, style (e.g. font color and size), screen position of items, display timing, etc. is determined by settings in trials timeline, trials screen and trials logic and is not reflected in the preview.
The structure of a preview stimulus component is a reflection of the composition in the stimulus set tree (Figure 3). Shown in (Figure 4), are the first two stimuli in an example preview. Each stimulus comprises a single component called Sentences
. The first component contains two component groups (CRB
and CGRB
) reflecting that the component contains a counterbalanced group of two groups. The second component contains a single component group CNB
