Abstract

Neophobia and neophilia can be lifesaving as they can facilitate foraging while avoiding predation or intoxication. We investigated the extent to which Goffin's cockatoos (Cacatua goffiniana) exhibit ecollogically relevant and quantifiable neophobic responses toward specific object properties. Twelve cockatoos were presented with 12 novel objects grouped into four distinct categories with unique features: size, color, reflective capacity, and shape. The cockatoos were tested by measuring their latency to approach a high-quality food reward for both novel and control scenarios. Age and sex did not affect the latency to approach food in the presence of a novel object in this species. Additionally, we found no significant differences between the objects of the reflective and color categories. This result is likely due to the plasticity of neophobic behavior related to the benefits and costs of approaching novel stimuli. The cockatoos were significantly slower to approach food in the presence of objects larger than their body size than objects of a similar or smaller size, a phenomenon possibly explained by the increased risk of approaching unknown objects large enough to be a potential predator. They were also significantly more hesitant to approach food in the presence of elongated objects, a phenomenon potentially explained by an ecologically relevant avoidance of snakes. The extent of this neophobia was statistically similar at a group level, indicating that avoidance of elongated and large objects could be an adaptive response aiding survival under natural circumstances and that snakes may impose strong selective pressures on this species.

四种不同物体特性对戈芬凤头鹦鹉(Cacatua goffiniana)接近潜伏期的影响。
恐新症和恋新症可以救命,因为它们可以促进觅食,同时避免捕食或中毒。我们研究了戈芬凤头鹦鹉(Cacatua goffiniana)对特定物体特性表现出的生态学相关的、可量化的恐新反应的程度。研究人员向 12 只鹦鹉展示了 12 个新奇的物体,这些物体被分为具有独特特征的四个不同类别:大小、颜色、反射能力和形状。测试方法是测量鹦鹉在新奇场景和对照场景下接近高质量食物奖励的潜伏期。年龄和性别并不影响该物种在出现新物体时接近食物的潜伏期。此外,我们还发现反光物体和彩色物体之间没有明显差异。这一结果可能是由于恐新行为的可塑性与接近新刺激物的收益和成本有关。当出现比鹦鹉体型大的物体时,鹦鹉接近食物的速度明显慢于接近类似体型或较小体型的物体,这种现象可能是由于接近大到足以成为潜在捕食者的未知物体的风险增加了。此外,在遇到细长物体时,它们也会更加犹豫是否要接近食物,这种现象可能是由于生态学上对蛇的回避。这种恐蛇症的程度在群体水平上具有统计学相似性,表明在自然环境下,避开细长和大型物体可能是一种有助于生存的适应性反应,而且蛇可能会对该物种造成强大的选择性压力。(PsycInfo Database Record (c) 2024 APA, 版权所有)。
