摘　　要：通过两个实验探讨了视觉表象任务信息的通达对表象加工眼动的影响。结果表明,在低通达条件下,表象任务的眼动复制了知觉任务的眼动;随着表象任务信息通达水平的提高,眼动的注视点平均持续时间、平均眼跳距离和平均眼跳时间会发生规律性变化;眼动控制与任务信息通达水平对表象眼动的影响存在不同的机制。实验结果佐证了眼动在视觉表象中起机能性作用的观点。Visual imagery is an important visuo-spatial representation, which has the same mental storage characteristics with visual perception （Romke, Kosslyn ＆ Hamel, 1997）, sharing the same brain mechanisms with visual perception （Kosslyn, Thompson ＆ Alpert, 1997; Ganis, Thompson ＆ Kosslyn, 2004）. As is known to all, fixation is the primary source of visual perception information, and eye movement is very important to visual perception. So, does eye movement also play an important role in the visual imagery processing？ There are two contrasting accounts for the phenomenon. The functional account hypothesizes that the encoding of each eye fixation during perception process participates, as an index in the location of the space in the subsequent image generation. In contrast, the epiphenomenal account views eye movements during imagery processing as the passive ＂spill over＂ from covert shifts of attention during the stage of image inspection, subsequently to its generation （Laeng ＆ Teodorescu, 2002）. Early studies （Jacobson, 1932; Lorens ＆ Darrow, 1962） reported increased oculomotor activity during visualization and during mental arithmetic. Recently, researchers found that subjects who fixed their gaze centrally during perception did the same spontaneously during imagery. The subjects who are free to explore during perception, but maintaining central fixation during imagery, showed decreased ability to recall the pattern. They concluded that the eye scan paths during visual imagery reenact those of perception of the same visual scene and eye movements during mental imagery are not epiphenomenal but assist the process of image generation （Brandt ＆ Stark, 1997; Laeng ＆ Teodorescu, 2002）. Actually, whether regular eye movements promote the representation processing relies on the level of eye movement regularity of change that regular change task information accessibility of visual imagery would cause. If task information accessibility level change inevitably leads to eye movement reg
