作者评估了年轻人样本中速度、记忆力和视觉扫描对数字符号得分的相对贡献(N = 87)。速度(符号复制)解释了 35% 的数字符号差异;其中只有一半归因于书写运动速度(姓名打印),这意味着感知速度的作用。视觉扫描测试(例如符号扫描)(平均)解释了 34% 的数字符号方差,其中大部分与感知运动速度无关,确立了视觉扫描效率在数字符号性能中的重要作用。相比之下,记忆测试(平均)只能解释 4% 到 5% 的数字符号方差:统计上显着,但显然是次要的,尽管视觉记忆复合材料与数字符号的相关性更强。然而,数字符号附带学习程序确实与其他记忆测量有一定的相关性,这表明它们是有效的记忆筛选设备。
The authors evaluated the relative contributions of speed, memory, and visual scanning to Digit Symbol score in a sample of young adults (N = 87). Speed (Symbol Copy) explained 35% of Digit Symbol variance; only half of this was attributable to graphomotor speed (Name Printing), implying a role for perceptual speed. Visual-scanning tests (e.g., Symbol Scan) explained (on average) 34% of Digit Symbol variance, much of which was independent of perceptual-motor speed, establishing an important role for visual-scanning efficiency in Digit Symbol performance. By contrast, memory tests (on average) explained only 4% to 5% of Digit Symbol variance: statistically significant but clearly subsidiary, although a visual memory composite correlated more strongly with Digit Symbol. The Digit Symbol incidental learning procedures did, however, correlate moderately with other memory measures, suggesting that they are valid memory screening devices.
