The person's attention to a surface appearance is followed by creating an image of a secondary effect on the surface appearance.
A primary effect may be imagined first because the secondary effect is usually a consequence of the primary effect. Anticipating the consequences of wet floors or icy roads have primary effects of sliding and secondary effects of injuries. Creating images of effects that are not perceived requires the presence of unchanged material objects, such as a wet floor.
The pauses to create images may be accompanied by movements of the pupils of their eyes.
