选择9～19岁被试120人，对简单反应、选择反应、图形匹配和句图匹配4项任务进行操作，结果表明，指数函数能较好地描述词“正方形”的转换、选择和反应速度随年龄增长而变化的特性，而不能较好地描述词“圆形”、“之上”句和“不在之上”句的转换速度随年龄增长而变化的特性，双曲线函数都不能较好地描述这些特性．
A total of 120 subjects aged 9 to 19 years old were selected to perform four tasks: simple response, selective response, pattern matching and pattern matching. The results show that the exponential function can better describe the conversion, selection and response speed of the word “square” Hyperbolic function can not be well characterized by the characteristics that change with age, but can not describe the change speed of the sentence “round”, “above” and “not above” with age. Describe these characteristics.
