Subjects set the extremities of a horizontal rod to appear equidistant from a central reference point, with or without central fixation. On either side, the contrast (salience) of the rod against the background was high or low. Extents to the left were set smaller than those to the right, an effect (LSU) which was stronger with central fixation, indicating that both hemispatial and anatomical pathway factors contribute. Reduced salience on the left increased rather than decreased the LSU, indicating the importance of attentional factors.
受试者将水平杆的两端设置为看起来与中心参考点等距，有无中心注视均可。在两侧，杆与背景的对比度（显著性）有高有低。左侧的范围设置得比右侧小，这种效应（左视野优势，LSU）在中心注视时更强，表明半空间和解剖通路因素都起作用。左侧显著性降低会增加而非降低LSU，这表明注意力因素的重要性。
