Episodic memory is defined as a memory system that consciously carries out recollecting one's subjective past experience and re-experiencing it. Through these mental activities, episodic memory is thought to make mental time travel retrospectively and prospectively possible, which is sometimes considered to be unique to humans. However, after a seminal study in scrub-jays by Clayton & Dickinson (1998), animal models of episodic memory have been developing and are starting to affect the concept of human episodic memory itself. This paper will concentrate on reviewing the studies that could encourage nonhuman animals to utilize memory — the properties are consistent with current definition of human episodic memory. Additionally, a discussion on the possibility to divide the system of episodic memory into two sub-processes and to study in animals the sub-processes of episodic memory will be undertaken.

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.

Recent researches have shown that dogs (Canis familiaris) possess a number of social cognitive abilities and communicate with humans in unique ways. Several researches suggest that dogs do not only use the overt features of humans (e.g., pointing, gaze) to find a hidden food in an object choice task, but also recognize the covert aspects of humans (e.g., knowledge) to predict the actions of them. This paper reviews evidence showing such excellent social cognition in dogs. Several comparisons between wolves and dogs suggest that human-like social skills by dogs have evolved as a by-product of domestication. Besides, some researchers argue the possibility of acquisition of similar social skills between dogs and humans through convergent cognitive evolution, which enabled them to communicate. The study of social cognitive skills in dogs will broaden our understanding of comparative social cognition.

Animal study in modern psychology has started as animal model study for general theory of human behavior. I examined pigeons and songbirds as models of human visual cognition and human auditory cognition respectively. Due to difference in anatomical structures and evolutionary history between the birds and humans, research to understand human cognition by avian models has limitation. On the other hand, researches with birds, far distant animals from human beings, are crucially important to understand visual and auditory cognitive faculty in general, because these faculties are not human-specific but widely spread in animal kingdom.

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.

Dogs have been domesticated by humans for more than 15,000 years. Now, dogs are the most closely related animals to humans in the world. Behind this evolutional process, the rare ability of dog's social cognition and to read human emotions and situations have been pointed out. The superior cognitive ability of dogs have achieved a unique niche in the human society, also nowadays its cognitive and learning ability has become a valuable research topic in the research field of animal psychology. Recent studies of human and dog suggest that these two species have been developed in the convergent evolution, on the process of domestication. So our best friend “dog” is not just domesticated animals, a “companion” who live together within human society as a unique species. This paper introduces some specific social skills of dogs and its biological properties, which have been revealed by molecular biological and cognitive science approaches in recent years.

Dogs have shared a common environment and similar selective pressures with humans through the time of domestication. About 60 years ago, Lorenz (1949) proposed that in many ways dogs are possibly more human-like than any other animals, including nonhuman primates. Only recently, however, scientific studies have evinced the specialized social skills of dogs. The relationships between humans and domestic dogs have deepened and changed, which highlighted or rather increased practical and ethical problems on the relationship between these two species. Some dogs are considered as members of the family, while some others are ill-treated and abandoned due to their behavior problems. In an attempt to examine how animal psychology can contribute to the dog-human relationship in modern society, this article reviews the application of behavior technology to behavior problems of dogs, the problems arising from the massive disparities in the treatment of dogs, and the view and traditional attitude towards animals in the theories of animal ethics.

Species comparison, whether explicit or implicit, is an essence in animal psychology but the role of species comparison differs among research paradigms. For example, associative learning and neuroscientific research examines proximal causes of behavior, and different species are compared in order to test the generality of mechanisms. Comparative cognition, on the other hand, examines what natural history influences cognition, and different species are compared in order to hypothesize ultimate causes that explain species difference found under experimental circumstances. Finding a synthesized interpretation of species difference across multiple paradigms does not facilitate better understanding what species similarities (and differences) mean. Instead, I discuss that more translation should be done between the paradigms. Translation brings critiques and novel ideas from one paradigm to the other, yet preserving ideas in each approach. It, therefore, allows us to interpret psychological phenomena from multiple perspectives, and thus provide novel insights to each other. Translations among the diverse paradigms within the discipline of animal psychology will also provide unique perspectives to research in human psychology.

The basis of affectively motivated helping of another in distress has long been debated by scholars in diverse disciplines. Work in rodents that took place more than 50 years ago suggested that rodents participate in affective communication. Now the author's laboratory has established an ethical and feasible test for rodent helping behavior that involves one rat freeing another from a plastic tube. The helping exhibited is consistent, reinforced, socially selective, and independent of immediate social contact. A recent modified version of the helping behavior test confirms that rats help a conspecific in need. In sum, the complex social behavior, expressed by rodents and primates including humans, validates the notion that mammals share a phylogenetic inheritance that promotes other-oriented affective behavior.

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.

Many researchers have investigated why and how animals benefit from each other in a group. Grooming is considered as prosocial behavior in animal societies; the groomer expends time and energy costs, while the groomee receives hygienic and physiological benefits. Based on the reciprocal altruism hypothesis (Trivers, 1971), many researchers have investigated grooming behaviors in primate species. In primates, individuals exchange grooming for grooming or other social benefits (e.g., tolerance for food, agonistic support, or infant handling). Researchers have also established and modified models of grooming reciprocity. In future researches, it would be valuable to investigate the effects of affiliative elationships, soliciting behaviors, self-rewarding, inequity aversion, and partner choice and partner switching on prosocial behaviors.
