“学-测经验”对前摄干扰监控及行为的修正作用

先前的学习与记忆对后继学习项目的削弱作用,称为前摄干扰。前摄干扰监控是指对前摄干扰造成的记忆成绩的削弱所进行的监督和调整。前摄干扰的监测偏差是指学习者对被干扰项目做出的监测判断比控制项目的判断等级高。研究考察"学-测经验"对前摄干扰监测、控制及干扰行为的修正作用。采用前摄干扰经典的A-B-D实验范式,利用三个实验分别考察前摄干扰监测偏差是否存在;考察增加"学-测经验"之后被试能否意识到前摄干扰的存在;以及增加"学-测经验"之后被试是否可以对前摄干扰进行修正。结果发现:(1)被试对前摄干扰存在监测偏差,且延迟判断的偏差更大。(2)在延迟判断条件下,通过增加"学-测经验",可以修正监测偏差。(3)通过增加"学-测经验",被试可以自主调控学习过程;用时较多的被试在自主调控学习过程之后能够完全克服前摄干扰。这一研究结果说明,"学-测经验"能够修正被试对前摄干扰的监控偏差;而当给予被试充分的学习时间,被试能够克服前摄干扰作用。研究为揭示前摄干扰的元记忆监控的规律、探索制约前摄干扰的因素及修正前摄干扰具有一定启示作用。

Influence of Acupuncture-moxibustion Treatment on Cognition Disorder

Objective： To observe the influence of acupuncture-moxibustion treatment on patients with mild cognition disorder. Methods： Sixty patients with mild cognition disorder were randomly divided into a treatment group and a control group, with 30 cases in each group. Acupuncture-moxibustion treatment was used in the treatment group, while Western medicine was taken by the patients in the control group. The differences of intra-group and inter-group comparisons were assessed by 3 measurement scales including Mini-mental State Examination （MMSE）, Activity of Daily Living （ADL） and Montreal Cognitive Assessment （MoCA）. Results： After treatment, the MMSE, MoCA and ADL scores of both groups were higher than those before treatment （P〈0.05）. The MMSE, MoCA and ADL scores of the treatment group have more noticeable improvement than those of the control group （P〈0.05）. Conclusion： Acupuncture-moxibustion treatment can effectively improve cognitive function of the patients with mild cognitive impairment.
