To determine the frequency of occurrence of closure difficulty, figure-size expansion, and figure-size constriction, 240 university students were administered the Graham-Kendall Memory-For-Designs test. Subjects were volunteers enrolled in undergraduate psychology courses and were between 18 and 23 yr. of age, male or female, and U.S. citizens. The purpose was to define a sampling of drawing styles exhibited in a normal group on this test. Each drawing style, or factor, was treated as an independent variable, and the frequency of occurence of each level (dependent variable) was compared via chi square. It was noted that a significant number of subjects exhibited some degree of closure difficulty with the designs (X2 = 101.72, p less than .01). Figure-size expansion was noted as extremely rare for this sample (X2 = 444.78, p less than .01). Finally, extreme figure-size constriction occurred significantly more often than either moderate or no contriction of the designs (X2 = 62.58, p less than .01).
为了确定闭合困难、图形大小扩张和图形大小收缩的出现频率,对240名大学生进行了格雷厄姆 - 肯德尔图形记忆测试。受试者为本科心理学课程的志愿者,年龄在18至23岁之间,男女不限,均为美国公民。目的是在此测试中定义一个正常组所表现出的绘图风格样本。每种绘图风格或因素都被视为一个自变量,通过卡方检验比较每个水平(因变量)的出现频率。结果发现,相当数量的受试者在设计图形时表现出一定程度的闭合困难(X2 = 101.72,p < 0.01)。对于该样本,图形大小扩张极为罕见(X2 = 444.78,p < 0.01)。最后,极端的图形大小收缩出现的频率明显高于设计图形的中度收缩或无收缩情况(X2 = 62.58,p < 0.01)。
