Stereotypic head twirls, but not pacing, are related to a 'pessimistic'-like judgment bias among captive tufted capuchins (Cebus apella).

异常刻板行为在圈养的非人灵长类动物中普遍存在，通常与危害福祉有关。然而，将所有这些重复、一成不变和显然没有作用的行为都视为同等重要，可能会产生误导，因为有些行为可能比其他行为更能反映压力。以往的研究表明，个体的情感状态可以从其对环境中中性刺激的评价偏差中推断出来。因此，在本研究中，为了评估刻板印象的个人的情绪状态，16个圈养的簇绒卷尾猴（Cebus apella）进行了测试的判断偏差范例和他们的粪便皮质激素水平进行了测量，以评估情绪状态的强度。与头部旋转水平较低的受试者相比，具有较高刻板头部旋转水平的卷尾猴在判断模糊刺激时表现出负偏差，并且粪便皮质激素水平较高。然而，刻板的步伐水平与猴子的情绪状态无关。这项研究是第一个揭示了刻板行为水平和“悲观”的判断偏见在非人类灵长类动物采用最近开发的认知方法之间的正相关关系。将评估动物情感效价（积极或消极）的认知测试与提供情感状态强度信息的激素测量相结合，有助于更好地理解动物的情感状态，从而更好地理解它们的幸福感。
Abnormal stereotypic behaviour is widespread among captive non-human primates and is generally associated with jeopardized well-being. However, attributing the same significance to all of these repetitive, unvarying and apparently functionless behaviours may be misleading, as some behaviours may be better indicators of stress than others. Previous studies have demonstrated that the affective state of the individual can be inferred from its bias in appraising neutral stimuli in its environment. Therefore, in the present study, in order to assess the emotional state of stereotyping individuals, 16 captive tufted capuchins (Cebus apella) were tested on a judgment bias paradigm and their faecal corticoid levels were measured in order to assess the intensity of the emotional state. Capuchins with higher levels of stereotypic head twirls exhibited a negative bias while judging ambiguous stimuli and had higher levels of faecal corticoids compared to subjects with lower levels of head twirls. Levels of stereotypic pacing, however, were not correlated with the monkeys’ emotional state. This study is the first to reveal a positive correlation between levels of stereotypic behaviour and a ‘pessimistic’-like judgment bias in a non-human primate by employing a recently developed cognitive approach. Combining cognitive tests that evaluate the animals’ affective valence (positive or negative) with hormonal measurements that provide information on the strength of the emotional state conduces to a better understanding of the animals’ affective state and therefore to their well-being.
