以３００名２０－７９岁成人为被试，并以１０岁段划分为６个年龄组，完成了非字词作业速度的随龄减慢及其与汉字作业的比较研究。结果表明：（１）数字鉴别、数字旋转、心算、符号数字和图形空间定位五项非字词作业速度均随增龄而显著减慢；（２）元分析结果表明３０－３９岁组到７０－７９岁组５个年龄组上述非字词作业反应时均为２０－２９岁组的平方函数，而且，非字词作业速度减慢的程度在６０岁后明显增大；（３）符号数字和数字鉴别两项非字词作业速度的随龄减慢均较相对应的汉字数字和汉字鉴别汉字作业更为明显。 Using 300 adults aged 20-79 as subjects and 10 age groups as 6 age groups, the age-appropriate slowing down of non-word work and its comparative study with Chinese assignments were completed. The results show that: (1) Five non-word job speeds of digital identification, digital rotation, mental arithmetic, symbolic figures and graphic spatial positioning slow down significantly with increasing age; (2) Meta-analysis shows that among 30-39 age groups, 70 The age group of -79 years old in the non-word job response are the square function of 20-29 years old group, and non-word work slowed down after the age of 60 significantly increased; (3) the number of symbols And digital identification of two non-word operating speed slower with age than the corresponding Chinese characters and Chinese characters identify the more obvious Chinese operations.
