在视觉信息的选择加工过程中 ,只有很少信息能够通过注意系统得到进一步的认知加工 ,其中视觉搜索起着十分重要的作用。本研究基于动态视觉信息注意追踪的研究 ,采用 3× 2× 2的实验设计 ,从如下三方面对注意追踪的规律进行了探讨 :(1)分心物数量 (1,5和 9)的变化对多目标注意追踪的影响 ;(2 )目标的显著性 (特征变化和特征不变 )对多目标注意追踪的影响 ;(3)目标运动形式 (目标随机运动和目标运动形式不变 )对多目标注意追踪的影响。研究结果表明 :(1)分心物数量的增加对目标的注意识别没有抑制作用 ;(2 )特征变化目标的注意识别速度显著高于特征不变的目标 ;(3)运动形式不变的目标较运动形式变化目标的注意识别速度快。
In the visual information processing, only a small amount of information can be further cognitive processing through the attention system, of which visual search plays a very important role. Based on the study of dynamic visual information attention tracking, this study explored the rules of attention tracking using the 3 × 2 × 2 experimental design in the following three aspects: (1) Changes in the number of distractions (1, 5 and 9) (2) the significance of the target (the characteristic change and the characteristic invariant) on the multi-target attention tracking effect; (3) the target movement form (the target random movement and the target movement form unchanged) Goal Watch the impact of tracking. The results show that: (1) the increase of the number of distractions has no effect on the attention recognition of the target; (2) the attention recognition speed of the feature change target is significantly higher than that of the invariant feature; (3) More attention than moving objects in the target recognition speed recognition.
