動物心理学における再現可能性の問題
Reproducibility in animal psychology
【論文PDF】

Reproducibility and reliability of research are fundamental points in science, as well as in animal psychology. In the field of animal psychology, researchers have used various species in various tasks and settings, so that the different considerations about reproducibility are need compared to the human research. Besides using the appropriate statistical analysis and improving experimental design, concrete theoretical background underlying each research seems to be important not only for improving the reproducibility between experiments that the same species were used but also in the situation where the different species were used. Because it is sometimes difficult to standardize the tasks and settings among researches in animal psychology, theoretical consideration would help to improve reproducibility of research as well as validity of interpretation of obtained results. Those efforts would also contribute to reduce unnecessary animal use from point of view of animal welfare.

Key words: reproducibility, animal psychology, comparative psychology, comparative cognition, inter-species replication, intra-species replication

研究の再現可能性や信頼性は科学にとって極めて重要であり,動物心理学にとっても同様である。動物心理学の領域においては,研究者は異なる動物種について異なる実験状況,実験課題を扱うため,ヒトを用いる研究とは異なる問題が生じうる。適切な統計解析の使用や実験計画の改善に加えて,同一種間・複数種間を問わず再現可能性を高めるためには,研究の理論的背景が重要である。動物心理学においては実験課題や実験状況の標準化が難しい場合があるため,理論的背景の存在は研究の再現可能性や解釈の妥当性を高めることに寄与する。こうした努力は,動物福祉的な観点から見ても,不必要な動物の使用を削減することに重要であると考えられる。
