掩蔽视觉分析在单一被试实验研究中的应用

The Application of Masked Visual Analysis in Single-Case Research

视觉分析是单一被试实验研究中主要的数据分析方法,一直以来都被研究者广泛使用。掩蔽视觉分析方法的产生主要是为了解决由单一被试实验过程中的实验操作以及视觉分析方法等因素可能造成的实验结果分析不准确的问题,包括实验进行期和数据分析期。该方法将假设检验加入单一被试实验研究中,提高了实验的内在效度。在实际运用中,与传统的视觉分析相结合,有利于提高对实验结果解释的精确度,同时也有利于研究人员更好地探讨实验中其他可能存在影响的变量。但视觉分析在实验过程中仍然面临着很多的问题,在实际应用时还应加以注意。

Visual analysis is the historic and widely accepted method to interpret data from studies using single-case research designs.The occultation masked visual analysis is mainly used to solve the problem of inaccurate analysis of experimental results caused by the experimental operation in the course of single subject experiment and other factors,such as visual analysis method,including the experimental period and the data analysis period.Masked visual analysis incorporates statistical hypothesis tests into a single-case research,improving the internal validity of the study.In practical application,it can be combined with traditional visual analysis to increase the accuracy of interpretation of the results.It would also allow researchers to better explore other variables in the experiment that might have an impact.However,masked visual analysis still faces many problems in the experimental process,so it should be cautious in its practical application.
