The guppy (Poecilia reticulata), a polyandrous livebearing fish, is a model organism in the study of sexual selection. This species exhibits sexual dimorphism, such as male body coloration (orange, black, or iridescence color spots). Although there is evidence of a preference for colorful males in female mate choice, a wide variation in male color patterns is found even in a population. Recently, there has been an increase in studies examining the postcopulatory processes involved in sperm competition and cryptic female choice in this species. If male traits that favor sperm competition and/or cryptic female choice correspond with traits preferred in female mate choice, then postcopulatory processes will reinforce the selection to colorful males. In contrast, if males with traits preferred by females are not favored by sperm competition and/or cryptic female choice, then postcopulatory processes will weaken the selection to colorful males. In this paper, I review studies of the relationships between male guppy coloration and female mate choice, sperm competition, and cryptic female choice, and discuss the possible factors that maintain the variation in male coloration.

Animal foraging behaviour has evolved in tight association with diverse forms of body structures species-specifically, because morphology shapes and affects perception, information processing, and subsequent motor control. Primates including humans possess skillful sensorimotor control such as tool-using, utilizing their arm-hand morphology. Birds also are capable of dexterous visually-guided behaviors despite the largely different body structures. This rises a question: what and how the body morphology constraints/facilitates behaviors in birds? The present article reviews research advance of sensorimotor control in birds. Specifically, it would be discussed about pecking, the analogous behavior to reaching and grasping in primates and tool-using. The author would suggest a research direction with the morpho-functional and embodiment views for comparative research on sensorimotor mechanisms underlying the dexterous foraging skills.

The saying "A dog (Canis familiaris) is man's best friend" and the term Jinba ittai (describing the connection between a horse [Equus caballus] and a human) express the affinitive interactions between humans and these animals. In this paper regarding psychology of learning, these interspecies interactions were considered to indicate that human behaviors change behaviors of these animals and vice versa. Such mutual influence is possible because humans and these animals have innate cognitive systems that allow them to process each other's behaviors, and because humans and these animals learn each other's behaviors. Thus, studies that investigated these cognitive systems and such learning were reviewed. Next, we looked at studies that examined these interspecies interactions during rearing or training. Finally, the reason why humans not only feel that dogs and horses can interact with them but also experience affinitive relationships with these animals was discussed. The innate and learned factors involved in the construction of these relationships were considered.

Individual animals show consistent differences in their behavioral tendencies. Some individuals are generally bolder, shyer, or more aggressive than others. This phenomenon is termed as animal personality or behavioral syndrome, and it has been observed in a wide range of animal species. In this article, we review the personality concepts and methodologies that has been used in two major study fields on this topic, i.e. the animal personality psychology and the behavioral syndrome research. Then, we shed light on how we can understand consistency in individual behavioral tendencies and how we can describe individual differences in animal behavior, by focusing on the differences and similarities between two study fields. Finally, we emphasize the importance of evolutionary framework for an integrated understanding of personality in non-human animals.

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.

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.

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.

Compared with dogs (<I>Canis familiaris</I>), the social cognitive abilities of cats (<I>Felis catus</I>) have not received much research attention, probably because cats are not considered to be as social as dogs. However, cats have in fact developed sociality in conspecifics and, needless to say, cat-human relationships after their domestication. This paper initially considers the reasons behind the underestimation of cats' social abilities, and then reviews social behavior among conspecifics and in the cat-human relationship. Several studies have provided evidence that cats possess social intelligence. Since their intelligence is considered to be expressed in different context from that of dogs, methods different from those used to study dogs are therefore needed for investigating their social abilities. Appropriate experiments or devices will undoubtedly unravel the high social intelligence of cats.

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.

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.

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.

Many studies have reported that wild and captive nonhuman primates have an advanced ability to understand causal relationships and use tools. However, the only studies investigating physical causal understanding in rodents under controlled experimental settings has been conducted in degus. The present studies conducted tool-use tasks in rats in an experimental setting, similar to tasks conducted in nonhuman primates and birds, and we used newly developed tasks to investigate their ability for physical causal understanding. In these tasks, rats were required to use tools to obtain food beyond their reach. Research 1 showed that rats chose appropriate tools to obtain food even when two novel tools were presented. In addition, Research 2 showed that rats were able to manipulate a tool according to the position of food. Our studies first suggest that rats have a primitive ability to understand physical causal relationships between pulling tools and approaching food. We propose the rat as an animal model to shed light on the evolution of physical causal understanding from rodents to humans.

Emotion is understudied in nonhuman animals despite broad interests in the topic. This is partly due to the difficulty in measuring subtle emotional reactions, such as physiological changes, under ecologically-valid situations. It is particularly challenging because the majority of traditional physiological measurements require animal participants to wear electrodes and head/body restraints in a laboratory. Recent advances in infrared thermography (IRT), and its use in measuring changes in animals' skin-temperature, offer suitable solutions for these challenges. This article reviews a growing body of research employing IRT in the study of animal emotions and identify both merits and shortcomings of IRT which need to be considered when designing experiments and observations. Also, we introduce our recent efforts to facilitate the use of IRT for the study of large-body animals, such as chimpanzees. Finally, we illustrate some of the critical future directions of IRT for the study of nonhuman animals. In conclusion, the study of animal emotion is more possible than ever before with this novel technology.

Bio-logging, i.e., the use of animal-borne sensors such as acceleration, GPS, electroencephalogram, and video camera, allows researchers to measure the behavioral and physiological data of animals as well as the variables of the environments in which the animals move. The derived animal-borne data, coupled with statistical modeling, can be used to understand ecologically significant phenomena, such as the navigation strategies of animals, across multiple spatiotemporal scales. For example, streaked shearwaters (Calonectris leucomelas) have evolved the ability to locate their home far away from the colony and adjust the onset time of their homeward journeys according to the distance to the home. We discuss the current trends and limitations in bio-logging science and propose future directions for integrating bio-logging with engineering, robot technology, and data science.

Nobody would dispute that cats and dogs are the two most popular species of companion animals for humans. It is no wonder that dogs are often considered to be the best friends and adopted family members of human beings: They developed the high social ability to communicate with humans during the two species' long history of co-habitation. However, it seems strange that cats are in the same position as dogs in human society, because they are more individual and less social than dogs. This review first presents the history of cat domestication. Next, it discusses the reasons why cats are now human companion animals despite such a history. This paper will discuss the cognitive and behavioral characteristics in cats that promote human-cat interaction and the similarities between cats and humans. Finally, it will discuss the significance of the study of cats' sociality.

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.
