Figure 3.

A typical view of the stimulus with target and pointer as the observers experience it during specific trials of a session. Although target and pointer are relatively unobtrusive (pictorial space is hardly affected by their presence), they are easily noticeable. The observer is in control of the spatial attitude of the pointer. This introduces a dynamic aspect that cannot be illustrated in the paper, but is quite important. It increases the experiential difference between the pointer and the (rigid) pictorial content, and increases the three dimensionality of the pointer, which extends all the way over the beeline implicated by the pointer. The coincidence or noncoincidence of the target with the beeline induced by the pointer becomes a vivid element of visual awareness. In the picture we have increased the sizes of pointer and target for the sake of clarity (see methods). Pointer and target have the same sizes, no matter where they appear in the picture.
