摘要: 本研究通过视觉表象旋转和扫描的眼动实验探讨表象的心理表征方式。实验一结果表明,眼动指标具有与反应时相类似的旋转角度效应。实验二结果显示,表象扫描的反应时和眼动指标都具有与知觉扫描加工一样的距离效应。由此可以认为,表象眼动与知觉眼动模式具有相似性;表象具有相对独立的心理表征方式并有其特殊的加工过程;表象的心理表征可以是形象表征,而非一定是抽象的命题或符号表征

Abstract: Visual mental imagery is one kind of mental imagery. Whether mental imagery can be one special kind of mental representation and has its mental process or not is not only focal in imagery research but also is important in the cognitive psychology. The aim of the present study was to investigate the mental processing of mental rotation and visual imagery scanning through eye movements.
Two experiments were conducted in the present study. There were 22 participants (11 males and 11 females) volunteered to take part in Experiment 1 and another 20 participants (10 males and 10 females) took part in Experiment 2. The Experiment 1 investigated whether mental rotation was based on mental image or abstract proposition with a 2 (picture type: ichnography, mirror image) × 8( rotation angle: 0°, 45°, 90°, 135°, 180°, 225°, 270°and 315°) within-subject design. In the Experiment 2, a 3(scanning distance: 0cm, 7cm, 10.5cm)× 2( cognitive type: perception and imagery) within-subject design was conducted to examine whether imagery could also be scanned and whether the oculomotor behavior during imagery reenacted that which occurred when perceiving the object.
In the Experiment 1, the results indicated that mental rotation time to recognize rotated pictures increased linearly with different angles of rotation, and the RT was the largest when the pictures rotated 180°. Besides, the oculomotor measures had also similar mental rotation effects during the processing. Subjects need to spend more saccade duration, fixation time and more numbers of saccade as well as more numbers of fixation to identify objects when the pictures were rotated from 0° to 180°. The results of Experiment 2 showed that imagery could also be scanned and eye scanpaths during imagery were similar to those during visual perception. That is, the time of scanning increased linearly with increases in distance during the imagery and perception phase. Moreover, regression analysis of the time and number of scanning supported the notion that the oculomotor behavior during imagery reenacted that which occurred when perceiving the object.
The present study demonstrated that mental imagery could be one special kind of mental representation and had its mental process. The mental representation of imagery was mental image but not abstract proposition in some special conditions.
