以空白单元格定位为实验任务,操纵序列点阵的分布,考察视觉短时记忆与视知觉的信息整合机制。实验一发现任务正确率与点阵1的圆点数呈近似U形关系。实验二发现在拐点前后被试的眼动模式从偏向于注视圆点位置转为偏向于注视空格位置。因此,视觉信息的分布模式调节整合策略,当处于视觉短时记忆中的圆点数在其容量之内时,采用图像—知觉整合策略,反之,则采用转换—比较策略。
Blank cell positioning for the experimental task, manipulating the distribution of the sequence lattice to investigate visual short-term memory and visual perception of information integration mechanism. The first experiment found that the correct rate of tasks and the dots of dot matrix 1 are approximately U-shaped. Experiment 2 found that the eye movement patterns of subjects before and after the inflection point turned from the biased position of the gaze dot to the biased position of the gaze space. Therefore, the distribution pattern of visual information regulates the integration strategy. When the number of dots in visual short-term memory is within its capacity, the image-perception integration strategy is adopted, otherwise, the conversion-comparison strategy is adopted.
