想象空间中物体搜索的阶段模型的证实

EXPERIMENT PROOF OF TWO-STAGE MODEL IN SEARCHING IMAGINED SPACE

用因素实验证明，在故事阅读产生的想象场景中，位于其中的观察者对身体四周物体的搜索分为两个阶段：第一阶段是目标方位的判断，认知加工时间的模式是前＜后＜左＝右；第二阶段是注意指向目标方位，从而辨别目标物体，认知加工时间的模式是注意点＜注意点对面＜注意点左侧＝注意点右侧。这两个阶段没有交互作用。反应时依赖于被试的视点。

Subjects read narratives describing directions of objects around an upright observer, who was periodically reoriented, and given a description of the objects in different positions around his body.Two-factor experiment supported that there were two stages in identifying which object was currentlylocated at the observer's front, back, right, and left. The first stage was identifying the directionassigned to the spatial relation by the relevant axis of the reference frame. The pattern of process timewas front < back < right = left, the second stage was identifying the object in the probed directions.The pattern of process time was focus < opposition to focus < left to focus = right to focus. The twostages were serial.
