Attention-dependent visual capture in double vision.
When the visual image of a body part, such as a finger, is doubled by a prism, the 'felt' position of that body part is captured by one of its visual images. Moving eye fixation from one to the other visual image is accompanied by a quick shift of the felt position. When focal attention is dissociated from foveation, the former determines visual capture. These new observations underline an active role of focal attention in intersensory integration and sensory-motor coordination of body parts.
