Preprocessed behavioral data from: Volitional spatial attention is lateralized in crows

Like humans and many other animal species, birds exhibit left-right asymmetries in certain behaviors due to differences in hemispheric brain functions. While the lateralization of sensory and motor functions is well established in birds, the potential lateralization of high-level executive control functions, such as volitional attention, remains unknown. Here, we demonstrate that carrion crows exhibit more pronounced volitional (endogenous) attention for stimuli monocularly viewed with the left eye and thus in the left visual hemifield. We trained four crows on Posner-like spatial cueing tasks using informative cues to evaluate their volitional top-down attention. The crows detected cued targets using either the left or right eye. As a measure of volitional attention, we calculated reaction time differences for detecting targets that were correctly (validly) and incorrectly (invalidly) cued, separately for the left and right visual hemifields. We found that cued targets were detected mo..., , , # Preprocessed behavioral data from: Volitional spatial attention is lateralized in crows [https://doi.org/10.5061/dryad.3j9kd51tm](https://doi.org/10.5061/dryad.3j9kd51tm) ## Description of the data and file structure This dataset contains all preprocessed behavioral data that is presented and analyzed in the corresponding manuscript. We trained four carrion crows (Corvus corone) in an operant conditioning chamber on two versions of a spatial cueing task and measured reaction times (**RT** [ms]) and target detection accuracies (Acc. [% correct]). Throughout the Task, Crows fixated their head position in a predefined area in front of a central monitor where experimental Stimuli were presented. On the side walls of the conditioning chamber, Stimuli were additionally presented on a Right- and a left-side screen. For all Crows, the Basic Task flow was as follows: Crows entered Fixation to start a Trial. Next, a spatial cue was briefly presented for 50 ms on one of the side screens (per...与人类及诸多其他动物类群类似，鸟类因大脑半球功能差异，在部分行为中表现出左右不对称性。尽管鸟类感觉与运动功能的偏侧化（lateralization）已得到充分证实，但高级执行控制功能（如意志性（内源性）注意（volitional (endogenous) attention））的潜在偏侧化仍未明确。本研究证实，小嘴乌鸦（Corvus corone）对左眼单眼观测、即左侧视觉野呈现的刺激，表现出更显著的意志性注意。我们采用提示性线索的波斯纳式空间线索任务，训练4只小嘴乌鸦以评估其意志性自上而下注意。乌鸦通过左眼或右眼检测线索提示的目标。作为意志性注意的衡量指标，我们分别针对左侧与右侧视觉野，计算了有效提示与无效提示目标的检测反应时差异。研究发现，线索提示目标的检测[原文截断]... # 预处理行为数据集来源：《乌鸦的意志性空间注意存在偏侧化》 https://doi.org/10.5061/dryad.3j9kd51tm ## 数据与文件结构说明 本数据集包含对应论文中展示与分析的全部预处理行为学数据。我们在操作条件反射箱中，对4只小嘴乌鸦（Corvus corone）开展了两种版本的空间线索任务实验，记录了反应时（RT [毫秒]）与目标检测准确率（Acc. [%正确率]）。 实验过程中，乌鸦需将头部固定在中央显示器前方的预设区域，实验刺激均呈现在该显示器上。条件反射箱的侧壁分别设有左侧与右侧显示屏，可额外呈现刺激。所有乌鸦的基础任务流程如下：乌鸦进入注视区域以启动试次，随后在其中一块侧屏上短暂呈现时长50ms的空间线索[原文截断]
