25 sixth grade students from diverse socioeconomic backgrounds were administered two Piagetian formal operational tasks (bending rods and balance beam) and a test of field independence. A Pearson product-moment correlation coefficient of .92 (p less than .001) was found between the two formal operational tasks. Correlation between the formal operational tasks and field independence were .81 and .77 (p less than .001) respectively. These values support the hypothesis of a unified stage of formal reasoning and also support the hypothesis that a degree of field independence is required for the development of formal stage reasoning.
来自不同社会经济背景的25名六年级学生接受了两项皮亚杰形式运算任务(弯曲杆和平衡梁)以及一项场独立性测试。两项形式运算任务之间的皮尔逊积矩相关系数为0.92(p小于0.001)。形式运算任务与场独立性之间的相关性分别为0.81和0.77(p小于0.001)。这些值支持了形式推理统一阶段的假设,也支持了形式阶段推理发展需要一定程度场独立性的假设。
