Abstract

Gaze following, orienting one’s gaze in the same direction as another individual, is a key component of social attention across species, and expected to play an important role in group contexts. To investigate its collective dimension, this study tested whether the number of conspecifics providing a gaze cue influences gaze following in pigeons (Columba livia). Using motion capture to track fine-scale head and body movements, we presented attention-getting stimuli to subsets of pigeons (demonstrators), while others (observers) could not see them. Observer pigeons followed the gaze of demonstrators, specifically toward the target object rather than a perceptually similar distractor, and the frequency increased with the number of demonstrators. We found no evidence for nonlinear effects under our experimental conditions. In group-living species like pigeons, multiple individuals looking in the same direction may serve as a more reliable social signal, highlighting the critical role of collective context in animal social cognition.

鸽子的注视跟随随着示威者的数量增加而增加

注视跟随，即将一个人的目光指向与另一个人相同的方向，是跨物种社会注意的关键组成部分，预计在群体环境中发挥重要作用。为了研究其集体维度，本研究测试了提供凝视线索的同种生物的数量是否会影响鸽子（Columba livia）的凝视跟随。我们使用动作捕捉技术来追踪精细的头部和身体运动，向鸽子的子集（演示者）提供吸引注意力的刺激，而其他鸽子（观察者）看不到它们。观察鸽子跟随演示者的目光，特别是朝向目标物体，而不是感知上相似的干扰物，并且频率随着演示者的数量而增加。在我们的实验条件下，我们没有发现非线性效应的证据。在像鸽子这样的群居物种中，多个个体朝同一个方向看可能是一种更可靠的社会信号，这凸显了集体环境在动物社会认知中的关键作用。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
