【摘要】：在视觉搜索中,特定背景与目标位置的多次联合呈现能够促进搜索绩效,这被称为背景提示效应。本研究探讨背景提示效应能否迁移到二维旋转后的视觉场景中去。选择大学生为被试,采用2(场景类型:重复、新异)×7(时间阶段:1~7)×3(旋转角度:0°、45°、60°)的三因素混合实验设计。被试在进行背景提示效应的学习后,随机分为三组分别在旋转了0°、45°、60°的场景中继续执行视觉搜索任务。结果发现:三组被试都习得了背景提示效应,且都迁移到了旋转后的场景中。这表明背景提示效应可能存在更高级的编码方式。
[Abstract]:In visual search, the combination of specific background and target position can promote the performance of search, which is called background prompting effect.The purpose of this study is to investigate whether the background cues effect can be transferred to two-dimensional rotating visual scenes.College students were selected as subjects, and a three-factor mixed experiment design was used for 2 (scene types: repetition, novelty) 脳 7 (time stage: 1: 7) 脳 3 (rotation angle: 0 掳, 45 掳, 60 掳).After learning the background cue effect, the subjects were randomly divided into three groups to continue to perform visual search tasks in a 0 掳/ 45 掳/ 60 掳scene.The results showed that all three groups acquired background cues and migrated to the rotating scene.This suggests that there may be a more advanced encoding method for the background cues effect.
