Sa. Brandt et Lw. Stark, SPONTANEOUS EYE-MOVEMENTS DURING VISUAL-IMAGERY REFLECT THE CONTENT OF THE VISUAL SCENE, Journal of cognitive neuroscience, 9(1), 1997, pp. 27-38
In nine naive subjects eye movements were recorded while subjects view
ed and visualized four irregularly-checkered diagrams. Scanpaths, defi
ned as repetitive sequences of fixations and saccades were found durin
g visual imagery and viewing. Positions of fixations were distributed
according to the spatial arrangement of subfeatures in the diagrams. F
or a particular imagined diagrammatic picture, eye movements were clos
ely correlated with the eye movements recorded while viewing the same
picture. Thus eye movements during imagery are not random but reflect
the content: of the visualized scene. The question is discussed whethe
r scanpath eye movements play a significant functional role in the pro
cess of visual imagery.
