信息加工阶段发展变化的机制

MECHANISM OF DEVELOPMENTAL CHANGE IN INFORMATION PROCESSING STAGES

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．

Children and adolescence (120) from 9 to 19 years of age were theied on four speeded tasks including simple reaction time, choice reaction time, figure matching and sentence- figure matching. Results show that the age increasing can not be followed by the time changing of 'square above or below round' sentence and 'square not above or below round' sentence, and it is almost constant. The other processing stages speded gradually with age. The variable characteristic of the agerelated time in the altering, reacting stages and translating stage of square wold is described well by exponential functions with a common rate of change, but not better in translating stages of round word, 'square above round' sentence and 'square not above round' sentence. The substance and mechanism issues of information process speed development are discussed.
