6～12岁儿童Flanker任务下的冲突适应效应

The Conflict Adaptation Effect in 6～12 Years Old Children:Evidence from Flanker Task

为了探讨6～12岁儿童冲突适应能力的发展,本研究使用经典的Flanker任务,考察了181名一至六年级小学生在冲突任务中的成绩。结果发现,冲突效应在各个年龄段都显著,但是冲突效应大小在不同年龄段之间没有显著差异;对于冲突适应效应,在反应时和准确率上都发现了冲突适应的证据,表现为不一致试次后的冲突效应减小和错误率降低,并且,冲突适应效应的大小在各个年龄段也没有差异。以上结果表明,对于6～12岁左右的小学生,冲突适应效应已经稳定存在,并且,不存在年龄差异。

The main aim of the present study was to explore whether the conflict adaptation effect existed in the 6 12 years old children. In the present study, we used the classic flanker task to explore whether the conflict adaptation effect exists in a sample of 181 children （6 -12 years old）. For the conflict effect, the present results revealed that the conflict effect was manifested in each age group and have no difference between different groups. For the conflict adaptation effect, the present results indicated that the conflict adaptation effect was also manifested in each age group and has no difference among different groups. Specially, for the RT data, the RT for the incongruent trial was faster when following an incongruent trial than following a congruent trial. The present results indicated the conflict adaptation effect was a stable conflict-induced behavioral adjustment process in the 6 - 12 years old children and has no significant age difference.
