Changes in temporal cues elicit rhythmic discrimination in rats (Rattus norvegicus) [0.03%]
时间线索的变化引起大鼠(Rattus norvegicus)的节奏辨别能力变化

Humans are capable of recognizing the temporal organization of a rhythm by perceiving its metrical structure even when it is evoked only by temporal alterations. There is also plenty of data suggesting that several animal species can track ...
Form over function: Striped skunks (mephitis mephitis) learn arbitrary visual patterns to solve the slat-pulling task [0.03%]
形式重于功能：臭鼬（mephitis mephitis）学会了解决拉板任务的任意视觉模式

Striped skunks are omnivorous generalists with patchily distributed food-two selection pressures that are purported to drive the evolution of cognition. Despite this, the cognitive abilities of skunks have rarely been tested. Using the slat...
Melodic and harmonic chromatic interval processing by pigeons (Columba livia) [0.03%]

Music is a ubiquitous feature of human behavior. Yet the origins of human musicality remain poorly understood. One attractive approach has investigated the distribution and components of musicality among nonhuman animals. Here I tested four...
One smell, two smells, intermixed, combined, or queued smells: What training procedure promotes the best generalization of odor detection by dogs? [0.03%]
一种气味，两种气味，混合、结合或排队的气味：哪种训练程序促进犬对气味检测的最佳泛化？

Drugs, bomb materials, fruits, and even medical conditions such as cancer are all stimuli that a dog's nose can be trained to detect, and the dog then can report reliable information about those stimuli in terms of presence or absence. This...
Sensitivity to immature skill deficits. Food sharing experiments in squirrel monkeys (Saimiri boliviensis) and common marmosets (Callithrix jacchus) [0.03%]
对不成熟技能缺陷的敏感性。普通狨猴和僧面猴的食物分享实验

Sandro Sehner et al.
Sharing food with immature individuals is costly and should therefore only occur when the benefits outweigh the costs. Accordingly, sharing typically decreases when immature individuals get older and become more proficient independent forag...

Photophobia, aversion for brightly lit environments, is commonly observed in laboratory nocturnal rodents such as mice and rats, as indicated, for example, by the light-dark box test. The universality of photophobia in laboratory nocturnal ...
Serial pattern learning: Pigeons (Columba livia) prefer an improving schedule over an initially easier fixed ratio schedule [0.03%]
序列模式学习： pigeons偏爱渐进改善的强化模式多于最初容易但最终难度超过渐进改善模式的固定比率强化模式

Serial pattern learning describes behavior in which a subject anticipates not only the time and effort needed for the next reinforcer but also the pattern of time and effort to reinforcers after the first. Chandel et al. (2021) found that p...
What is it like to hear quantities? Testing dolphins on classic number estimation using a sonar setup [0.03%]

The featured article by Sakurai and Tomonaga (2024) in this issue has set out to test to what extent dolphins can estimate relative differences between pairs of object numbers by echolocation. For this they used three consecutive experiment...
The effect of delta-9 tetrahydrocannabinol and methamphetamine on sustained attention in the jumping spider (Trite planiceps) [0.03%]
大麻酚和甲基苯丙胺对游走壁虎持续注意力的影响研究

Decreasing responsiveness to repeated visual stimuli (i.e., the inability to sustain attention) in jumping spiders (Salticidae) parallels that found in humans. In humans, drugs affect vigilance, and previous work on salticids has shown that...
Cyclical variations in acoustic features within the song sessions of humpback whales (Megaptera novaeangliae) [0.03%]
座头鲸歌声时段中声学特征的周期性变化

Song sessions produced by humpback whales recorded off the coasts of Hawaii and Colombia show recurrent patterns of acoustic variation across consecutive songs. Analyses of intra-individual variations within continuous song sessions reveale...
