【摘要】：背景线索效应是指重复出现的场景中背景所包含的位置信息,关系信息,时间序列信息可以成为更加高效探索目标的提示线索,是视知觉研究领域的热点,对场景知觉的研究具有很重要的意义。本研究介绍了背景线索效应的来源,定义,分类,研究方法和实验逻辑。在此基础上分析了背景线索效应的学习内容、学习实质和学习特点。研究包括三个实验,第一个实验是综合实验,采用视觉搜索任务范式,使用汉字材料分别考察了背景容量,空间布局,背景意义等对空间背景线索的影响,同时拟合背景容量和反应时的函数关系,分析函数图的斜率和截距特点来确定背景效应的加工特点,结果发现以汉字为材料时出现了空间背景线索效应,背景线索效应的加工不包含对汉字语义的加工,这种搜索促进作用主要以注意引导为主,也包含知觉辨认加快的过程。实验二和实验三是在变化觉察任务范式下进行的,也是采用的汉字材料,实验二发现在该条件下一样出现了空间背景线索效应,实验三改变刺激项目的空间布局但保持固定的伴随条件结果发现也存在明显的反应时差异,这说明该条件下出现了客体关系背景线索效应。三个实验的结果表明1.空间线索效应,客体关系线索效应不会因为实验材料,实验任务的改变而消失。2.背景线索效应的加工过程是一个双调节过程,既可以引导注意,又能加快对项目的确认。3.背景线索效应对视觉信息的加工优于对语义信息的加工。4.被试可以灵活的运用空间位置,客体关系等信息加快对目标的确认。
[Abstract]:Background cues effect refers to the location information, relationship information and time series information contained in the background in the repeated scene, which can become a more efficient clue to explore the target, and it is a hot spot in the field of visual perception research. This study introduces the origin, definition, classification, research methods and experimental logic of the background clue effect, and then analyzes the learning content of the background clue effect. The study includes three experiments, the first is a comprehensive experiment, using visual search task paradigm, using Chinese character materials to examine the background capacity, spatial layout, The influence of background meaning on spatial background clue, fitting the function relation between background capacity and reaction time, analyzing the slope and intercept characteristics of function map to determine the processing characteristics of background effect. The results showed that the spatial background clue effect appeared when Chinese characters were used as the material, and the processing of background clue effect did not include the processing of Chinese character semantics. Experiments two and three were conducted under the paradigm of change perception task, and were also Chinese characters materials. Experiment two found that the spatial background clue effect appeared under this condition. Experiment three changed the spatial layout of stimulus items but maintained the fixed concomitant conditions. The results showed that there was also a significant difference in response time. The results of three experiments show that 1. Space cues effect, object relationship clue effect does not result from experimental materials. The processing process of background cues effect is a double regulation process, which can lead to attention. Background cues effect on visual information processing is better than semantic information processing .4. participants can flexibly use spatial position, object relationship and other information to speed up the target confirmation.
