Rhythmic entrainment, or synchronization, to musical rhythm is universally observed in almost all human culture; however, in non-human animals, this kind of behavior has been demonstrated only by some specific species. Thus, exploring the evolutional origin and the psychological substrate for this capability is an attractive research topic. This article reviews recent studies tackling this question and relevant researches, then, introduces a hypothesis explaining the origin of the prominent capability for rhythmic synchronization in humans.

Recent technological advances made it possible to record postural changes of moving animals in behavior/cognition research. Although several technologies are available for this purpose, one underexplored possibility is the use of an infrared motion-capture system, which excels at tracking subtle and rapid 3D movements of animals. We explored this possibility by developing a system optimized to track saccadic head movements of large-billed crows (Corvus macrorhynchos). We custom-built a motion-capture room, "Corvid Tracking Studio", in which birds can freely interact with conspecifics/objects while infrared cameras track the reflective markers attached to the birds' heads. We also developed a head-calibration method that reconstructs the 3D positions of each bird's eyes and beak tip with respect to those of the head markers. We then tested accuracies of the head-orientation coordinate system reconstructed from the eye-beak coordinates of a bird and confirmed that estimated errors were all within a degree (in Euler angles). We thus show that a motion capture system has a good potential to examine subtle and rapid movements of moving animals with several customizations.

Prosocial behaviors have been considered a hallmark of humans in the past. However, accumulating experimental data in comparative cognitive science have revealed that nonhuman animals also show prosocial behaviors. Nevertheless, its evolutionary path has remained unclear despite a great deal of recent research effort. In this paper, I first review experimental studies on prosocial behaviors in nonhuman primates, by focusing on the influences of request behavior and social closeness. Then, I evaluate some factors that have been thought to play an important role in facilitating the convergent evolution of prosocial behaviors (inequity aversion, interdependence, tolerance) based on experimental data. I finally propose some possible future studies to explore the evolutionary path of prosocial behaviors, by referring to the previously discussed psychological mechanism that seems to support nonhuman primates’ prosocial behaviors (Yamamoto & Takimoto, 2012).

Recent research on animal behavior has identified a set of common cognitive and behavioral principles that underlie animal collective decision-making. Although endeavor toward synthesizing knowledge about collective decision-making by different species has already begun, human collective phenomena, which have mainly been investigated by social scientists, are still largely left behind from this scope. However, delineating uniqueness and commonality of human collective decision-making in biological contexts is critically important to understand nature of human collectivity. Toward this end, this paper first defines the concept of collective decision-making from a biological perspective. We then review several recent key findings on collective behavior by several animal species (eusocial insects in particular), and argue that a set of fundamental processes such as positive feedback, nonlinear conformity bias and quorum-sensing, commonly underlie human and non-human collective decision-making. We sketch some future research directions to promote cross-fertilizations between the biological and social sciences for a better understanding of collective phenomena by humans and non-human animals.

The domestic cat is a very popular companion animal. However, there is very little work focusing on cat-specific physiology and behavior. In this review, we introduce our studies uncovering scent signals for species- and sex-recognition and the behavioral significance of the silver vine response in cats. Cat urine emits a specific catty smell. Our chemical analysis identified a sulfur-containing volatile organic compound, 3-mercapto-3-methyl-1-butanol, that is detectable in the urine of cats but not of dogs and humans. In addition, its level varies between sexes; its level is markedly higher in intact males than in castrated males or females. These indicate that the sulfur-containing compound is a urinary scent signal involved in species- and sex-recognition in cats. The other characteristic in cats is the behavioral response to silver vine, which comprises licking and chewing the plants, rubbing against the plants, and rolling over on the plants. Previous studies identified some bioactive compounds designated as matatabilactones from the plants, but little is known about why cats do the response to the plants. Our analyses found that nepetalactol which was missed in the plants is a potent bioactive compound for the response and stimulates the μ-opioid system which is responsible for the euphoria in humans. Nepetalactol has the repellent activity of pest insects such as mosquitoes. The rubbing and rolling responses to the plants transfer nepetalactol onto the feline fur that repels mosquitoes. The licking and chewing of the plants changes not only emission levels of nepetalactol and matatabilactones but also their contents which increase bioactivities toward cats and mosquitoes. These findings improve our understanding of the species-specific physiology and behavior in cats.

The ability to recognize and evaluate others is considered to be an important ability in selecting cooperative partners. There have been some studies on this ability in both humans and nonhuman animals, however, little empirical research has been conducted to examine how horses perceive humans. Here, we investigated whether horses can evaluate the problem-solving ability of humans in an unsolvable task. We showed horses a pair of two experimenters, one who can open the lid of a container (problem solver) and the other who cannot open the lid of the container (problem nonsolver), trying to open the lid of the container either with or without food in it. Gaze duration toward each experimenter was recorded and used as a proxy measurement of the attention of the horses. Horses watched the problem solver longer than the problem nonsolver in the food condition. They also watched the problem solver for longer in the food condition compared to the no food condition. These results suggest that horses can recognize the problem-solving ability of humans.

During domestication/evolution process of dogs, dogs have acquired human-like nonverbal communication skills, such as gaze and pointing following by humans, and gaze alternative behavior toward the owners. These skills, especially using eye gaze, are believed to promote the co-habituation of dogs in human society. Not only the communicative function of dog's eye-gaze with humans, it works as to form bonding between them. Eye-gaze from dogs to their owners increased urinary oxytocin, and the owner showed affiliative interactions with their dogs, which in turn, stimulate oxytocin release in dogs. Oxytocin is a hypothalamic neuropeptide stimulate maternal behavior as well as social interactions. Therefore, human and dogs can form a biological bonding via oxytocin positive loop in both sides. This type of positive loop was not observed in wolves, suggesting that dogs have acquired this function in their domestication process. Future behavioral genetic research will reveal the critical genes responsible for human-dog interaction, which would shed a light on the critical questions; "why", "how" and "when" dogs become a Man's best friend.

Birds and primates typically attend to an object of interest using sensitive spots in the retina (i.e. the fovea). Therefore, the direction of their gaze indicates their focus of attention. Recent technological advances in miniature wearable devices allow us to examine birds' gaze behaviors in detail when they are freely moving, and even when they are flying. In this review, I aim to outline current knowledge about how birds use their gaze to attend to an object of interest, and what they are attending to when they are engaging in various natural activities, such as navigation, vigilance, and social interaction. I also aim to outline both strengths and limitations of techniques available for bird gaze-tracking. As a relevant example, I introduce a recent study that utilized Inertial Measurement Unit to examine how pigeons move their gaze while attending to landscapes and flockmates during their homing flights. Overall, I believe that recent sensor technologies offer a promising avenue for examining birds' visual attention and the associated mental processes in natural contexts.

Recent studies have revealed similarities and differences among hominids: humans, chimpanzees and bonobos. Cooperation is one of the human hallmarks, but its evolutionary basis can be found both in chimpanzees and bonobos. Comparison among the three evolutionary closest relatives would tell us about how cooperative society evolved. For this purpose, food sharing is an ideal target behavior to examine, since it is a typical cooperative behavior and prevails in the three hominids. The author has observed food sharing events among wild bonobos in Wamba, Democratic Republic of Congo. This data depicts several features of bonobos' food sharing that cannot be seen in chimpanzees. Bonobos often share plant food, which can often be obtained without any cooperation or specialized skills, sometimes even when the same food items are abundant and easily available at the sites. Bonobo recipients may beg to strengthen social bonding. Frequent plant-food sharing among bonobos may shed light on the evolution of courtesy food sharing which may be seen only in humans and bonobos.

Octopuses, a member of molluscan class, posse well-developed nervous system such as lens eyes that is anatomically similar to our own, and the relative proportion of brain to body is equivalent to vertebrates. Octopuses are also characterized with their muscular highly sensitive sensory receptors, namely, suckers on their arms. Due to these biological uniqueness, octopuses have been a target for psychological studies and were reported their advanced abilities for learning and memory, which are achieved via visual and tactile perceptions. All of these findings have come from experiments that tested single sensory perception (i.e., visual or tactile). On the other hand, it is known in vertebrates that they can integrate multiple sensory information, by which they can vividly image their environments. In this review, we will briefly introduce our knowledge for biology of octopuses with special reference to their cognition, and we will shed light on an idea for cross-modal perception in octopuses, which is based on our on-going projects for visual and tactile learning, and manipulation of arms in tropical octopuses inhabiting the coastal waters of the Ryukyu Archipelago.

Animals, including humans, communicate by transmitting various kinds of information to each other. Although individuals of the same animal species share a channel of communication, it is sometimes difficult to explore the nature of communication between different animal species. In this study, the transmission of information between humans and horses was examined regarding the three-term contingency in behavior analysis. We introduced studies in which signals from humans are discriminative stimuli for horses, and in which signals from humans are reinforcing stimuli for horses. Possibility and difficulty of information transmission between humans and horses were discussed.

The field of comparative cognitive science has focused especially on mammals and some birds because of their phylogenetic closeness with humans and their larger brain compared to "lower vertebrates" such as fish. However, recent comparative analyses and conceptual models in the field of animal psychology and/or animal behavior propose that cognitive abilities have evolved in response to ecological and/or social factors. In addition, it has been shown that brain organization are largely conserved throughout the vertebrates, suggesting that lower vertebrates may have more sophisticated cognitive abilities than previously thought. Therefore, to reveal the phylogenetic distribution of cognitive abilities we should also examine lower vertebrates. In fact, ethologists have demonstrated diversity of social and ecological complexities in fish, which are good candidate for helping to reveal how cognitive abilities evolved. Therefore, I focus on fish cognition in this review. Recent studies have shown that some fish behave depending on the types of information they receive. As examples, I introduce studies about flexible decision-making and social cognitive abilities in cichlid fish in Lake Tanganyika, and cleaner wrasse. Finally, I discuss the evolution of cognitive abilities in different ecological contexts.

Behavioral synchronization is shown not only between intra-species but also between inter-species. Previous studies reported that behavioral synchronization occurs between dogs and their owners by affiliative bonds and dogs' social skills for communicating with humans acquired by domestication. Horses also have such bonds and skills like dogs, however, there have been few empirical studies of behavioral synchronization between horses and humans. Therefore, we investigated whether the gait synchronization occurs between the horse and his/her familiar human participant while they were walking together by using angular statistics and how horses and umans interacted by analyzing entrainment. Only when human gait rhythm was controlled to be constant, gait synchronization between horse and human participants was found, though entrainment occurred only in humans. When horses and humans were walking in a more natural and uncontrolled situation, entrainment occurred in both horses and humans, though their walk adjustment did not reach synchronization. These results suggest that gait synchronization occurs between horses and humans and walk adjustment from humans is involved in such synchronization.

Recently, there have been more and more chances to talk about our study in English even in domestic conferences, symposiums or workshops in Japan. However, unfortunately, almost all of us have not received enough training for making English presentation yet. Therefore, I would like to introduce the very basics of pronunciation, making slides, way of talking and answering questions from the audience to help beginners through their first English oral presentation.

Group living mammals have a distinct characteristic: when conspecific animals are together, they show a better recovery from experiences of distress. This phenomenon, termed 'social buffering', has been found in rodents, birds, non-human primates, and also in humans. This phenomenon is well-observed in bonded dyad; the mother-infant or pair-bonded dyads. Social contact, including allogrooming, appears to have a very positive influence on the psychological and physiological aspects of social animals, including human beings. These relationships depend on the neuroendocrine system, especially oxytocin. Oxytocin is released by affiliative social contact in dyads and can ameliorate stress and anxiety in both sides. This review overviews the classic finding of social buffering in animals and describe the recent findings of neuroendocrinological mechanisms for social buffering.
