Accordingly, sharing typically decreases when immature individuals get older and become more proficient independent foragers. Providers would gain more if they could adjust food sharing not only to immature age but also to their skill level. Such sensitivity to others' skill deficits is expected to be rare, but may be found in species with high prosociality and other-regarding preferences, such as cooperative breeders. Here, we compared the food-sharing patterns of cooperatively breeding common marmosets (Callithrix jacchus) and closely related but independently breeding squirrel monkeys (Saimiri boliviensis) under two conditions. In the baseline condition, food was easily accessible whereas in the experimental condition, individuals had to solve a puzzle to access the food. We found that the cooperatively breeding marmosets, but not the independently breeding squirrel monkeys, shared more when immatures lacked the skill to obtain the food from the apparatuses. Skill sensitivity might be associated with the presence of other-regarding preferences and a strong proclivity to proactively share food during baseline conditions. This proclivity has evolved in marmosets, but not squirrel monkeys, in the context of cooperative breeding and may facilitate the emergence of skill recognition, information donation, and teaching.

Several species hunt mobile prey, placing demands on working memory and selecting for sociocognitive abilities such as predicting prey behavior. The mechanisms by which apes overcome foraging and hunting challenges are difficult to elucidate. Field investigations provide rich data sets but lack experimental control, limiting the gamut of questions they can answer, while experiments with captive subjects offer lower generalizability to real-world situations. Virtual environments (VEs) present a compromise, combining experimental specificity with proxies of realistic situations. In this study, chimpanzees and bonobos moved through a three-dimensional VE using a touchscreen. All subjects learned to chase and catch moving rabbits, some exhibiting high success rates even in the presence of large obstacles. Success in trials with a first-person (FP) viewpoint was much higher than in trials presented from overhead, suggesting that the immersive nature of FP trials helped subjects to understand their location in the environment better than when they took a top-down view. Data were analyzed using generative computational agent models, identifying that subjects occasionally employed anticipatory hunting strategies, but more often used a direct chasing strategy. This study validates the use of VEs as an experimental paradigm, demonstrating that apes can understand the behavior of moving agents in situations of varying complexity and that computational modeling can be utilized to delve into behavioral data at a fine-grained level and identify which of several cognitive strategies they fit best.

Pavlovian conditioning enables individuals to anticipate a biologically significant event or unconditioned stimulus, such as resource availability, when paired with another event, such as a blue light, also known as a conditioned stimulus (CS). Considering that individuals' prior experiences with habitat features may influence their preference for producer or scrounger responses, this study aims to assess the impact of resource-associated signals on the group produce index. Specifically, the study seeks to (a) outline a setup for goldfish (Carassius auratus) incorporating renewable patch zones, (b) evaluate the CS's effect on the proportion of producers, and (c) develop an agent-based model capturing the CS's effect on the proportion of producers. Eight goldfish were used, with half undergoing a delayed Pavlovian acquisition protocol. Pavlovian-trained and control fish were assessed under signal and nonsignal conditions. The findings reveal that the producer index in the signal condition was higher for the Pavlovian group than the control group. To simulate conditions to those observed in fish, we developed an agent-based model where Pavlovian agents oriented themselves toward the nearest patch zone when the CS was present. The results mirrored those observed in fish, indicating an advantage derived from preexposure to the CS. This study contributes to the investigation of individual disparities and the impact of learning within the framework of the producer-scrounger game.

We investigated the interaction of these types of learning in a series of five experiments with six adult male rhesus monkeys. We presented monkeys with three types of image sets. Scene sets were random images of natural scenes or cityscapes with no perceptually evident pattern by which to rank them. Relations among these images had to be learned through trial and error. Patterned sets were shapes that varied systematically along a physical dimension such as size such that a single rule for ranking them could be applied across images. Disordered sets were the same as Patterned sets, but monkeys were trained to rank them in an arbitrary order that was not consistent with differences along a physical dimension. Monkeys learned Scene sets more quickly than Patterned sets and Disordered sets, suggesting that monkeys memorize the relations between images relatively easily. In follow-up experiments, we found that monkeys also learned rules for the Patterned sets, indicated by the fact that they generalized performance to novel images and reversed ranks across the whole set after training with a single reversed pair. In Experiments 4 and 5, we investigated the interaction of memorization and relational rule learning with compound image sets that included both systematic physical variation and arbitrary visual content. We found further evidence that monkeys ordered images by both memorization and rules.

The universality of photophobia in laboratory nocturnal rodents rises questions on its corresponding behavior in nature and on what adaptive value may have led to the selection of this behavior during biological evolution. Nocturnality alone is insufficient to explain photophobic behavior, as nocturnal rodents show reduced roaming in the day just because they are sleeping and not because they are choosing to avoid a possibly aversive daylight. On the other hand, a natural behavior more directly related to the photophobia observed in the laboratory is selenophobia (moonlight avoidance), which in free-ranging rodents can be operatively defined as the reduction of exploratory and foraging activities in moonlit nights compared with dark nights. In the case of selenophobia, factors related to nocturnality are ruled out, and light-related factors can be easily isolated. Selenophobia has been found in a wide variety of nocturnal rodents, for which it may represent an antipredatory adaptation. A technology-aided study of selenophobia may strongly contribute to a better understanding of its nature, of the relative contributions of instinct and learning to this behavior, and of its neural underpinnings. In particular, new behavioral and neurophysiological technologies, for example, miniaturized radiocollars, freely accessible testing chambers equipped with infrared video cameras, animal-borne miniaturized video cameras, and noninvasive electrophysiological recordings, may be of particular usefulness to shed light on selenophobia.

Analyses of intra-individual variations within continuous song sessions revealed that songs consistently cycled through stages of acoustic complexity. At time scales spanning tens of minutes, cyclical variations likely reflected the diving behavior of singers. Changes over shorter time frames suggest that singing humpback whales may also systematically modulate the acoustic complexity of individual sounds during song production, both by gradually morphing units and by varying the number of times they repeat sound patterns. Comparable cycles were evident across years and populations. Cyclical variations within song sessions can reveal how much time and energy singers spend producing tonal versus frequency-modulated/broadband elements. Tonal components are generally more difficult to localize spatially but easier to detect over long distances, suggesting that singing humpback whales may dynamically vary sound production in ways that affect both sound transmission and auditory spatial processing.

Subsequent relationship dynamics provide a foundation for the evolution of societal norms and associated encephalization in social taxa, like primates and dolphins. Some cultures within these families benefit from interactions with other mammal species but accounts of any wild animals attempting to provision humans are extremely rare. In this article, we present 34 cases of both sexes and all age classes of killer whales (Orcinus orca) offering prey and other items to people who were on boats (n = 21), in the water (n = 11), and on shore (n = 2) in four oceans. A total of 18 species were offered-six fishes, five mammals, three invertebrates, two birds, one reptile, and one seaweed. In almost every case the whales awaited a human response before subsequently reacting. The occurrence of these events suggests a limited cost to exploratory behaviors in some populations of this species. We suggest these apparently nonrandom cases may be representative of interspecific generalized altruism. This behavior may represent some of the first accounts of any wild predator intentionally using prey and other items to directly explore human behavior and thus may highlight the evolutionary convergence of intellect between highest order primates and dolphins.

It is still unknown, however, whether the auditory environment can influence canine affect. This study therefore explored the influence of auditory stimulation on the short-term mood of dogs. Forty-five pet dogs were randomly assigned to one of the three conditions of auditory stimulation (a control of silence, classical music, or audiobook). While being exposed to the auditory stimulus relevant to their condition, each subject animal participated in a commonly employed cognitive bias test, during which their latency to approach a bowl placed in one of the three ambiguous positions was recorded. All dogs were successfully trained, with intact animals taking fewer sessions to reach criterion than neutered subjects. As expected, dogs became increasingly slower to reach the bowl the further it was positioned from the positive location. The animals' latency to reach the bowl placed in the ambiguous positions did not differ significantly between auditory conditions. The study suggests that canine affect is not influenced by the auditory environment, at least in the short term.
