摘要: 以 7岁、9岁、12岁小学生和成人大学生为被试 ,让他们在 5种实验任务中进行期望值判断 ,以探讨儿童期望值判断的发展。结果表明 :(1) 7岁儿童就能够在简单任务中进行概率推理和正确判断事件的期望值 ;(2 )儿童对概率和价值两个维度相乘关系的认知呈现发展趋势 ,但其乘法规则的运用仍逊于成人水平。而成人期望值判断的成绩有较大的个体差异。 (3)在期望值相同的情况下 ,儿童更注重事件发生的概率而相对忽视价值

关键词: 儿童, 概率, 期望值

Abstract: The study was to explore children's development of judgment of expected value in Chinese primary school Subjects from grade 1, grade 3 , grade 6 and college students participated in the study They were asked to give judgment of expected value in 5 kinds of tasks The results showed: (1) Even 7 year old children could make probability inference and have correct judgment of expected value in simple tasks; (2) Children's judgment of expected value developed with age, they consider both probability and value dimensions, and gradually find their relation of multiplication, but their level of use of multiplication rule is lower than adults (3) Under the condition that expected value is equal, children pay more attention to probability than to value

Key words: children, probability, expected value
