A stimulus may be composed of one or more components. Stimuli that are composed of multiple components are described as compound stimuli. Components are composed of one or more component groups and component groups themselves may also be compound in nature.
Blended: blended component group contains two or more component groups that need to be blended. Groups may contain different types of items (e.g. image and text).
Counterbalanced: counterbalanced component group contains multiple component groups that need to be counterbalanced.
Discrete: discrete component group contains a list of stimulus items.
WARNING: Removing a component group will also remove:
If components has multiple children (Figure 1), compound stimuli are produced and a composition strategy for building the stimuli needs to be determined. Click Composition: sequential to set the composition strategy.
Sequential: compound stimuli will be composed by selecting items from each group sequentially.
Random: compound stimuli will be composed by selecting items from each group randomly.
Random: recompose: compound stimuli will be composed by selecting items from each group randomly. Stimuli will be recomposed randomly for each set of trails that allocate this stimulus set.
