变化知觉的另一面——变化盲

The Other Side of Change Perception:Change Blindness

人们经常会探测不到事物的变化,这种现象被称为变化盲(change blindness),它和变化觉察是变化知觉的两个面。对变化盲的研究主要集中以下几个方面:对变化盲现象产生的原因辨析以及从刺激属性和注意广度、知识经验、个体差异、文化背景等分析变化盲的影响因素;近几年来内隐变化觉察也引起研究者的争论和重视;此外,对变化盲的多(跨)通道和错误元认知研究也成为一种新的研究动向。同时,变化盲研究在其表征机制、加工方式以及内隐变化觉察等方面尚存在争议,变化盲的错误元认知研究以及变化盲的认知神经心理研究则是此领域的薄弱环节。

People often fail to detect the changes to objects or scenes. This phenomenon is called ＂change blindness＂. It is the other side of change detection. Researches on change blindness mainly focused on several aspects. The reasons of change blindness was one of researchers＇ major concerns, and factors that influenced change blindness was another main subject, which includes properties of stimulus, attention breadth, context knowledge, individual differences between observers and culture backgrounds. Recently, the question of implicit change detection has drew many researchers＇ notice, and great attention is paid to change blindness through multi （cross）-channels and change blindness blindness （CBB） as well. However, disagreements arose about change blindness and its representation mechanisms, processing methods and implicit change detection. Besides, studies on change blindness based on CBB and cognitive neuroscience need to be further explored.
