據(jù)外媒報(bào)道，狗被稱為人類的最佳朋友,，但原來未必只對人類忠心,。
《動(dòng)物認(rèn)知》期刊刊登的研究報(bào)告指，若機(jī)器人表現(xiàn)友善,，并成功幫助狗只找出隱藏的食物,，它們會將機(jī)器人當(dāng)真人看待，證明只要有食物,，狗能效忠任何有人類特征的東西,。
實(shí)驗(yàn)中，一部看似健身儀器,，但兩邊支架戴上白色手套的機(jī)器人,，用“手”指向收藏食物的地方，研究員則在旁記錄狗只的反應(yīng),。機(jī)器人最初只發(fā)出嗶嗶聲與狗兒溝通,，后來計(jì)算機(jī)屏幕顯示出人臉，結(jié)果狗兒會跟從指示找到食物的成功率較高,。
其后，狗主入房與機(jī)器人握手談話,，機(jī)器人再播出預(yù)錄的人聲說出狗狗的名稱,，指向食物。結(jié)果狗狗不但服從指示,，更上前嗅機(jī)器人的手套,，凝視屏幕上的人臉，當(dāng)它是個(gè)奇怪的“人類”,。 （生物谷Bioon.com）

Sensing sociality in dogs： what may make an interactive robot social,？

This study investigated whether dogs would engage in social interactions with an unfamiliar robot,， utilize the communicative signals it provides and to examine whether the level of sociality shown by the robot affects the dogs’ performance. We hypothesized that dogs would react to the communicative signals of a robot more successfully if the robot showed interactive social behaviour in general (towards both humans and dogs) than if it behaved in a machinelike， asocial way. The experiment consisted of an interactive phase followed by a pointing session,， both with a human and a robotic experimenter. In the interaction phase,， dogs witnessed a 6-min interaction episode between the owner and a human experimenter and another 6-min interaction episode between the owner and the robot. Each interaction episode was followed by the pointing phase in which the human/robot experimenter indicated the location of hidden food by using pointing gestures (two-way choice test). The results showed that in the interaction phase， the dogs’ behaviour towards the robot was affected by the differential exposure. Dogs spent more time staying near the robot experimenter as compared to the human experimenter,， with this difference being even more pronounced when the robot behaved socially. Similarly,， dogs spent more time gazing at the head of the robot experimenter when the situation was social. Dogs achieved a significantly lower level of performance (finding the hidden food) with the pointing robot than with the pointing human； however,， separate analysis of the robot sessions suggested that gestures of the socially behaving robot were easier for the dogs to comprehend than gestures of the asocially behaving robot. Thus,， the level of sociality shown by the robot was not enough to elicit the same set of social behaviours from the dogs as was possible with humans， although sociality had a positive effect on dog–robot interactions.
