【摘要】：通过改变目标刺激和非目标刺激的编码效力,探讨重复知盲发生的机制。采用RSVP任务,操作目标的重复性与目标的性质(实验1a和实验2)、位置(实验1b)和非目标的字频(实验2),对比不同条件下第二个重复刺激的正确报告率。结果是:(1)非目标为字母、目标是字母时的重复知盲大于目标为电脑符号时的重复知盲。(2)非目标为字母、目标为电脑符号时,目标在1和3位置时出现了重复知盲,而在2和4位置时没有出现重复知盲。(3)当非目标为高频汉字、目标也是高频汉字时的重复知盲大于目标为符号时的重复知盲。(4)当目标为高频汉字、非目标是高频汉字时出现了重复知盲,而非目标是低频汉字时重复知盲消失。实验结果表明,字母和汉字条件下,目标刺激和非目标刺激的编码效力都会对重复知盲产生影响,支持竞争假设。
[Abstract]:By changing the coding effectiveness of target and non-target stimuli, the mechanism of repetition blindness was discussed. Using the RSVP task, the repeatability of the target and the properties of the target (experiment 1a and experiment 2b, position (experiment 1b) and non-target word frequency (experiment 2) were compared with the correct reporting rate of the second repeated stimulus under different conditions. The result is that the non-target is a letter, and the goal is that the repeated knowledge blindness when the letter is a letter is greater than the repeated knowledge blindness when the target is a computer symbol. The non-target is a letter. When the target is a computer symbol, the target has repeated knowledge blindness when the target is in the position of 1 and 3. However, there is no repetition knowing blindness at 2 and 4 positions.) when the non-target is a high-frequency Chinese character, and the target is also a high-frequency Chinese character, the repetition recognition blindness is greater than the repeated knowledge blindness when the target is a symbol.) when the target is a high-frequency Chinese character, the target is a high-frequency Chinese character. When the non-target is high frequency Chinese character, repeated recognition blindness appears, but when non-target is low frequency Chinese character, repeated recognition blindness disappears. The experimental results show that the coding effectiveness of both target and non-target stimuli has an effect on repetition blindness under the condition of alphabetical and Chinese characters, which supports the competitive hypothesis.
