飞行场景中表征动量的地标吸引效应和排斥效应

设置了安全和危险两种地标, 采用诱导运动范式考察了飞行场景中运动目标和关联地标的相对关系、目标运动方向及关联地标的意义特征和呈现时间对运动目标位置判断的影响。结果显示: (1)飞行场景中飞机的表征动量较强; (2) 趋近安全地标的表征动量大于远离安全地标的表征动量, 趋近危险地标的表征动量小于远离危险地标的表征动量, 安全地标呈现出地标吸引效应, 而危险地标呈现出地标排斥效应; (3) 高关联的安全和危险地标使飞机的表征动量不受运动方向影响; (4) 保持间隔期间呈现的安全和危险地标使飞机的表征动量增加。结论 :表征动量的地标效应受制于地标意义特征, 表征动量受到目标和地标之间的因果关系和情景意义的影响。

Landmark attraction effect and landmark repulsion effect on representational momentum in airplane movement scene

The term representational momentum has been used to describe a forward displacement of the final position of a moving target and also as an explanatory mechanism for that forward displacement. Landmark attraction effect refers to the remembered orientation of a target shifted towards the orientation of a surrounding context object. Previous studies on moving targets and landmarks have been limited to the effects of physical properties, such as the size of the stimulus, or the speed of movement, on the displacement of another object. The present study focused on the effects of the situational significance, the relative relationship between the moving target and the relevant landmark, the movement directions of the target and the presentation time of the landmarks on the judgment of the moving target position.
