Abstract

日常生活におけるイヌの役割の多様化に伴い、ヒトはイヌに様々な訓練を行うようになった。しかし、訓練に用いるコマンド音の特徴的な変化とイヌの行動の関係を評価する研究が少ない。本研究では基礎訓練を終了した成犬4頭に対し、3音素で構成される2種類のコマンド「オイデ」と「ハウス」の子音を変化させて提示し、その音声コマンドに対するイヌの反応を評価した。コマンド「オイデ」の子音変化に対する平均反応スコアは、無処理のコマンドと比較して有意に低下した。さらに、提示されたコマンドに対してイヌが反応を完了させるまでのタイムは、無処理のコマンドと比較して有意に遅かった。コマンド「ハウス」の反応スコアならびにタイムは「オイデ」と類似傾向を示した。これらのことから、コマンドによる差はあるものの、イヌは日本語の3音素のコマンドにおいても音声の微妙な変化を認識できることが示唆された。

Since dogs are used for a wide variety of purposes by humans, it is very important to acquire knowledge about their perceptual and learning abilities. In this study, four dogs (Canis familiaris) were trained to "O-I-De ("come" in English)" and "Ha-U-Su ("house" in English) reliably response to recorded commands. The experimenter (trainer) sat on a chair to restrict body movements, wore black glasses to eliminate eye contact with the dog, and used recorded verbal commands presented via an equipment. Performance was low in all cases compared with the true command condition. The response score to the change of the consonant of command "O-I-De" has decreased compared with the true command. In addition, it was significantly slow at time from the presentation of the command to the completion of the response compared with the true command. A response score of command "Ha-U-Su" showed similar to "O-I-De" a tendency. Moreover, response time was compared with the true command and the consonant change command was slow. The results suggest that dogs might recognise a slight change in a Japanese command of three phonemes as well as the results of English commands.
