翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Ecological validity ： ウィキペディア英語版 Ecological validity In research, the ecological validity of a study means that the methods, materials and setting of the study must approximate the real-world that is being examined.〔Brewer, M. (2000). Research Design and Issues of Validity. In Reis, H. and Judd, C. (eds) ''Handbook of Research Methods in Social and Personality Psychology.'' Cambridge:Cambridge University Press.〕 Unlike internal and external validity, ecological validity is not necessary to the overall validity of a study.〔Shadish, W., Cook, T., and Campbell, D. (2002). ''Experimental and Quasi-Experimental Designs for Generalized Causal Inference'' Boston:Houghton Mifflin.〕 ==External validity versus ecological validity== Ecological validity is often confused with external validity (which deals with the ability of a study's results to generalize). While these forms of validity are closely related, they are independent—a study may possess external validity but not ecological validity, and vice versa.〔〔 For example, mock-jury research is designed to study how people might act if they were jurors during a trial, but many mock-jury studies simply provide written transcripts or summaries of trials, and do so in classroom or office settings. Such experiments do not approximate the actual look, feel and procedure of a real courtroom trial, and therefore lack ecological validity. However, the more important concern is that of external validity—if the results from such mock-jury studies generalize to ''real'' trials, then the research is valid as a whole, despite its ecological shortcomings. Nonetheless, improving the ecological validity of an experiment typically improves the external validity as well. The original meaning of 'ecological validity' defines it more narrowly as a property of stimuli in perceptual experiments. The popular use, broadly equivalent to 'realism', has overtaken it, at least in A Level Psychology circles. For the original (and some feel correct) use, see the entry on 'ecological validity - perception' and especially the paper by Hammond, 1998, which is referred to there. This can be accessed at: http://www.albany.edu/cpr/brunswik/notes/essay2.html . 'Representative design' captures the popular usage of ecological validity and can be used in its place. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ecological validity」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
