摘　　要：采用2种视角条件和2种信息量,以回忆正确率作为绩效测量指标,要求40名被试在不同条件下回忆在计算机屏幕上学习过的静态矩阵图像中的特征信息,考察静态图像的视角和信息量对图像短时记忆的影响。实验结果表明:①信息量对静态图像的短时记忆有显著影响,目标信息量越少,回忆正确率越高;②视角大小对静态图像的短时记忆有显著影响,呈现视角较大的图像的回忆正确率显著较高;③视角和信息量存在交互作用,视角大小的影响主要发生在信息量较大的时候,大视角有利于静态图像的短时记忆。2 × 2 group-within design was used to examine the influence of visual angle and the quantity of the target stimulus on short -term memory of static images. Taking memory accuracy as dependent variable , 40 subjects were asked to remember the location of black panes of 5 ×5 matrix on the 17 computer screens . The results showed that both visual angle and the quantity of the target stimulus affected performance of short - term memory of static images. When the quantity of information was fewer or visual angel was bigger, the subjects＇ performances were better. In addition, there was a significant interaction. Only when the number of the target stimulus was more, the bigger visual angle could promote short-term memory of static images.
