In two experiments, rats received minimal (16) pairings of one auditory conditioned stimulus (CS) cue with a sucrose reinforcer, and extensive (112) pairings of another auditory CS with that reinforcer. After sucrose was devalued by pairing...
Extinction and latent inhibition of within-event learning are context specific [0.03%]
消亡和潜在抑制作用在事件内学习中具有情境特异性

Exposure to a solution composed of an odor (almond) and a taste (salt) produced a context-independent preference when rats were subsequently tested with almond under a salt appetite. Postcompound exposure to either the almond or the salt al...

Rats (rattus norvegicus) anticipated the arrival of a food pellet unconditioned stimulus (US) even when the conditioned stimulus (CS) signaled no overall change or a substantial decrease in the overall rate of US occurrence. Pellet USs were...
Simultaneous and sequential choice as a function of reward delay and magnitude: normative, descriptive and process-based models tested in the European starling (Sturnus vulgaris) [0.03%]
奖励延迟和大小对同时选择与顺序选择的影响:欧洲乌鸦(Sturnus vulgaris)中的规范,描述及过程化模型的测试

The authors analyze prevalent theoretical and empirical quantitative models of choice using data from European starlings (Sturnus vulgaris). The different models originate from diverse lines of thinking, including optimal foraging theory, d...

Despite many demonstrations of numerical competence in nonhuman animals, little is known about how well animals enumerate moving stimuli. In this series of experiments, rhesus monkeys (Macaca mulatta) and capuchin monkeys (Cebus apella) per...
Task constraints mask great apes' ability to solve the trap-table task [0.03%]

Researchers have investigated animals' causal knowledge with a task requiring subjects to use a tool to bring a reward within reach whilst avoiding a trap. Previous studies have suggested limitations in the ability of several species to avo...

Previous work from our laboratory has demonstrated that rats display a preference for directional responding over true place navigation in the Morris water task. The present study evaluated the range of situations in which this preference i...
The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas [0.03%]
全景图像的信息内容(二):非矩形实验竞技场中的视图-based导航

Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M....
The information content of panoramic images I: The rotational errors and the similarity of views in rectangular experimental arenas [0.03%]
全景图像的信息量(I):矩形实验竞技场中的旋转误差和视角相似性

Wolfgang Stürzl et al.
Animals relocating a target corner in a rectangular space often make rotational errors searching not only at the target corner but also at the diagonally opposite corner. The authors tested whether view-based navigation can explain rotation...
Spatial memory of domestic dogs (Canis familiaris) for hidden objects in a detour task [0.03%]
狗(家犬)在绕道任务中对隐藏物体的空间记忆

Sylvain Fiset et al.
Spatial memory of domestic dogs (Canis familiaris) for hidden objects was investigated via a visible displacement problem of object permanence with a detour paradigm. Experiment 1 showed that dogs were able to spontaneously locate a disappe...
