This study aimed to investigate how three groups of people of differing ages, and with differing knowledge of the species, perceived the emotional state of African elephants () managed in captive and semi-captive environments. Fifteen video-clips of 18 elephants, observed during three different daily routines (release from and return to the night ; interactions with visitors), were used for a free choice profiling assessment (FCP) and then analyzed with quantitative methods. A general Procrustes analysis identified two main descriptive dimensions of elephant behavioral expression explaining 27% and 19% of the variability in the children group, 19% and 23.7% in adults, and 21.8% and 17% in the expert group. All the descriptors the observers came up with showed a low level of correlation on the identified dimensions. All three observers' groups showed a degree of separation between captive and semi-captive management. Spearman analyses showed that stereotypic "trunk swirling" behavior correlated negatively with first dimension (free/friendly versus sad/bored) in the children's group; second dimension (agitated/confident versus angry/bored) amongst the adults; and first dimension (active/excited versus agitated/bored) amongst the experts. More studies are needed to investigate other potential differences in assessing elephants' emotional states by visitors of different ages and backgrounds.
本研究旨在调查三组年龄不同、对该物种了解程度不同的人群如何看待圈养和半圈养环境中非洲象的情绪状态。15段包含18头大象的视频片段,这些片段是在三种不同的日常活动(早晚进出圈舍、与游客互动)中观察到的,用于自由选择剖析评估(FCP),然后采用定量方法进行分析。一般普罗克汝斯忒斯分析确定了大象行为表达的两个主要描述维度,在儿童组中分别解释了27%和19%的变异性,在成人组中分别为19%和23.7%,在专家组中分别为21.8%和17%。观察者提出的所有描述符在确定的维度上显示出较低的相关性。所有三个观察者组在圈养管理和半圈养管理之间都表现出一定程度的差异。斯皮尔曼分析表明,刻板的“卷鼻”行为在儿童组中与第一个维度(自由/友好与悲伤/无聊)呈负相关;在成人组中与第二个维度(激动/自信与愤怒/无聊)呈负相关;在专家组中与第一个维度(活跃/兴奋与激动/无聊)呈负相关。需要更多研究来调查不同年龄和背景的游客在评估大象情绪状态方面的其他潜在差异。
