Template:VisualStimulusProperties
enum PresentationMode (rw)
This property determines the way a stimulus is presented. It is one of the following:
- ShowHide
- The stimulus is initially invisible, and visible while being presented.
- Intensify
- During presentation, the contrast of the stimulus is increased.
- Grayscale
- During presentation, the stimulus is displayed in grayscale rather than color.
- Invert
- During presentation, the stimulus appears color-inverted.
- Dim
- During presentation, the contrast of the stimulus is reduced.
- HideShow
- The stimulus is initially visible, and invisible while being presented.
float DimFactor (rw)
Determines the contrast ratio between presentation and non-presentation in Dim and Intensify modes. In Intensify mode, values greater 1 will result in a brighter appearance during presentation; in Dim mode, values greater 1 will result in a darker appearance during presentation. Due to saturation effects, the result may not be as expected.
