The world is full of uncertainty, often requiring decisions that involve unknown outcomes. Responses to uncertainty, or risk, have been widely studied, revealing both species-level and individual differences. Risk studies have focused on a ...
Is it weird in here and does comparative cognition suffer from main-character syndrome? [0.03%]

Comparative cognition can make itself more relevant to those who care largely (or entirely) about humans by making itself less WEIRD and less focused on humans. That feels nonintuitive, I know, but psychology has long wanted to find itself ...
Cross-cultural and cross-species comparisons of mutual gaze and infant emotion: Challenging Western, Educated, Industrialized, Rich, and Democratic (WEIRD) and Barren, Institutional, Zoo, And other Rare Rearing Environments (BIZARRE) assumptions [0.03%]
跨文化与跨物种的相互凝视和婴儿情绪对比：挑战西方、受过教育、工业化、富裕和民主（WEIRD）以及荒凉、机构化、动物园及其他罕见成长环境（BIZARRE）假设

In this study of mutual gaze (MG) and emotion, using multiple groups of chimpanzee infants to compare with multiple groups of human infants, we provide a methodology to assess two deeply rooted assumptions: (1) Psychological outcomes in chi...
Changes in exploratory behavior in male Lister-Hooded rats in early and late adulthood [0.03%]

Exploration encompasses a range of behaviors aimed at gathering information about the environment, which is then encoded and stored in memory. Memory processes support exploration by retaining past experiences, facilitating habituation to n...
Inside the parrot beak-and-tongue apparatus: Unlocking a model system for dexterity research [0.03%]
揭秘鹦鹉的鸟喙与舌头装置：解锁灵巧操作研究模型系统

Dexterity, the flexible and precise control of objects, requires the integration of cognitive abilities, motor coordination, and anatomical specializations. Due to the evolutionary significance of the opposable thumb, dexterity research has...
The state and expectations of interrater reliability in nonhuman personality research [0.03%]
非人动物人格研究中的互评可靠性的现状与期望

Establishing interobserver reliability is a key step for asserting concordance in personality ratings. Yet, typical measures of reliability-such as intraclass correlation coefficients (ICCs)-are not just reflective of whether raters agree o...
Species-dependent gazing behavior of emotional facial expressions in dogs (Canis familiaris) and adult humans (Homo sapiens) [0.03%]
狗（Canis familiaris）和成人（Homo sapiens）对情绪面部表情的注视行为取决于物种
Heini Törnqvist,Gray S Atherton,Liam Cross et al.
Heini Törnqvist et al.
Emotional expressions play an important part in social communication of dogs and humans, but comparative studies between dogs and humans are rare. In addition, little is known about how emotions are perceived across species and how attentio...
How search images limit competition: The role of attention in collective foraging [0.03%]
搜索图片如何限制竞争：注意力在集体觅食中的作用
Keren Ighalo,Noam Miller
Keren Ighalo
Many species forage collectively, and this will shape how they search for prey. However, theories of visual attention and search image formation have not considered social foraging, and studies of collective foraging rarely consider cogniti...
Gibbons (Nomascus leucogenys), siamangs (Symphalangus syndactylus), and chimpanzees (Pan troglodytes) account for proportional probabilities in a two-choice task [0.03%]
白掌长臂猿（Nomascus leucogenys）、西猩猩（Symphalangus syndactylus）和黑猩猩（Pan troglodytes）在二择任务中表现出概率匹配行为

Jessica Crimston et al.
Probabilistic reasoning-the ability to predict outcomes based on the likelihood of different possibilities-is a key component of numerical cognition and is critical for navigating uncertain environments. However, it is unclear whether this ...
Learning to discriminate between shapes generalizes to novel stimuli in North American river otters (Lontra canadensis): A preliminary study on perceptual categorization [0.03%]
北美水獭（Lontra canadensis）区分形状的辨别学习能泛化到新颖刺激：关于感知分类的一项初步研究
Jessica J Wegman,Catina Wright,Kenneth Tyler Wilcox et al.
Jessica J Wegman et al.
Perceptual categorization is grouping objects based on similar physical features. Otters may use categorization to classify predators, prey, and conspecifics. This study was the first to examine whether North American river otters (Lontra c...
