心理学准实验技术的回顾与反思

Review And Reflection of Quasi-experiment Techniques in Psychology

实验法作为心理学研究中的重要研究方法,在研究中存在人为性较强、与现实情景相距太远的缺陷。准实验设计在自然情景中进行实验,能较好的反映现实环境和体现研究的生态效度。而准实验设计的松散,实验控制的不严格对实验结果的影响也难以避免,现代研究工具的发展和统计技术的进步正在增进和改变着这一现状。在心理学对其研究质量不断提升的进程中,研究方法上的多元化成为必然趋势。

Experiment is a very important method in psychology study. Its human factors make it far different from real world. While the method of quasi-experiment is designed in natural environment, it can reflect real things and has good zoology validity. Quasi-experiment design is usually not as rigorous as experiment design, but modem equipment and statistical techniques can help improve it.
