采用眼动研究范式，通过两个实验考察靶刺激变换与情景信息属性对情景再认的影响。实验一结果显示，靶刺激变换对情景再认、靶刺激所属兴趣区的凝视时间均有显著影响，这表明在情景再认过程中，观察者会有意识地搜索靶刺激，靶刺激具有诊断效应；实验二应用了知觉信息与语义信息重合和分离两种情景材料。结果显示，观察者对语义信息的首次注视次数显著多于知觉信息；观察者对知觉信息和语义信息分离条件下语义信息的首次注视时间显著长于重合条件下。这一结果提示，在情景识别过程中，靶刺激具有注意优先性，但其优先性会受到知觉信息启动的干扰。

A scene was defined as a semantically coherent view. The human visual system can gather an incredible amount of information about a scene in a glance. When a rapid sequence of scenes is presented, the subjects can accurately detect a target （Potter, 1975 ）. Why can a human distinguish the target from the distracter？ Friedeman （1979） believes that the scene identity can be inferred from the identification of one or more key objects. Some research pays attention to the characters of key objects. Some evidence supports that a scene can be identified from the scene semantic information. However, others argue that low spatial frequency information may induce scene identification. Torralba ＆ Oliva et al （2006） presented the contextual guidance model that is comprised of two parallel pathways, one pathway computed local saliency and the other computed the global features. The saliency involved a bottom-up factor and processing of the global features was affected by top-down knowledge. The present study included two experiments; some scene materials about human safety and eye movement paradigm were used. Experiment 1 examined whether scene recognition was ＇affected by target objects or not. A 2 （safe scene/dangerous scene） x 3 （substitution/deletion/identical） design was used. A total of 12 participants were asked to learn 18 scenes. And after the learning phase, they were tested for the recognition of changed scene or identical scene. Experiment 2 was designed to examine the influence of information on eye movement during the scene recognition. Experiment 1 showed that the recognition rate of a scene and the dwelling time on interest areas of the target location were significantly different under the three object changing conditions. The results suggested that scene recognition depended on the target objects. Experiment 2 found that semantics information greatly attracted attention, but the first fixation time was longer if semantics information was apart from perception information. So, we conclude that semantic information has attention prioritization, but it may be affected by the priming of perception information.
