【摘要】：以真实情景图片为材料,探讨局部亮度与语义关系对情景识别的影响,以及情景背景线索和语义关系的获得。实验一结果显示,被试对有无语义关系情景图片的识别反应时存在显著差异,且对拼接图片的识别正确率更高,反应时更短。实验二探讨了局部亮度与呈现时间变化条件下情景背景线索和语义关系的获得。结果发现,情景语义关系和背景信息的获得受到局部亮度变化和呈现时间的影响。这表明,语义关系和呈现时间对情景识别存在显著影响,而且这种影响与情景背景线索和语义关系的获得有关。呈现时间越长,越易获得情景语义关系。局部亮度变化越小,背景线索越易获得,呈现时间的影响越小。
[Abstract]:The influence of local luminance and semantic relationship on scene recognition and the acquisition of background clues and semantic relations were discussed based on the real scene images. The results of experiment 1 showed that there was significant difference in the recognition time of the images with or without semantic relation, and the correct recognition rate and the reaction time of the stitched images were higher and shorter. In the second experiment, the relationship between the background clues and the semantic relationship between the local luminance and the presentation time is discussed. The results show that the semantic relationship and the acquisition of background information are affected by local luminance change and presentation time. This indicates that semantic relationship and presentation time have significant effects on scene recognition, and this effect is related to the acquisition of contextual cues and semantic relationships. The longer the presentation time, the easier it is to obtain situational semantic relationships. The smaller the change of local brightness, the easier to obtain the background clues and the less the influence of presentation time.
