Outline of Final Research Achievements

The present study revealed, (1) Japanese fire-bellied newts, a kind of amphibians, learn food aversion conditioning over various kinds of CS food; (2) Amount of consumed CS foods determines strength of food aversion conditioning in Japanese fire-bellied newts; (3) Social interaction with conspecifics after conditioning do not alleviate food aversion condition in Japanese fire-bellied newts; (4) Japanese fire-bellied newts do not show significant latent inhibition in food aversion conditioning. These findings are first demonstration of food aversion conditioning and its determinants in amphibians.

Academic Significance and Societal Importance of the Research Achievements

食物嫌悪条件づけはトカゲ等の爬虫類では生じるのに対して，カエルやイモリでは生じないことが報告されていた。これに対し，本研究は両生類において食物嫌悪条件づけが生じることや成立要因を初めて明らかにした。アカハライモリの学習や認知を検討するための行動実験法は確立していない。本研究の成果は，両生類であるアカハライモリの学習や認知をほ乳類等と比較するための方法論を提供するとともに，注意や情動といった心的機能の起源を解明するための糸口となるものである。
