In contrast, while heterospecific interaction largely refers to predator ― prey interaction, occasional instances of cooperative behavior can be found, for example, the interaction between domesticated animals and humans. Domestication involves breeding animals for generations to familiarize them with humans without fear. A major behavioral characteristic of domesticated animals is tameness which is divided into two categories. One is reluctant to avoid humans (passive tameness) and the other actively approaches humans (active tameness). Until now, however, little is known about the genetic, behavioral and neurological basis of these two categories of tameness. Here, we briefly review genetic and neurological research on tameness. Next, we explore the relationship between tameness and social cognitive skills of domesticated animals, such as dogs.

Although the basic knowledge has been accumulated, sociality involves complex issues. Moreover, practical methodologies for social management remain controversial. In this paper, we overview the current studies and practices of social management on four great ape species (chimpanzees, western lowland gorillas, and Bornean and Sumatran orangutans) housed in Japanese zoos to advance the sociality discussion. We first describe the fundamentals of sociality in animals. Then we explore important topics of sociality, including social relationships in captivity, all-male group formation in chimpanzees and gorillas, group living in orangutans, and welfare of disabled and geriatric individuals. Although the number of sociality studies has recently increased, to maximize the positive effects of captive social living, more detailed understanding of the effects of social factors on animals using scientific methodologies is important.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129078329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127448143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To perform the reconstruction, bats compare their original emission with returning echoes that have been changed by the surroundings. In natural environments, echolocating bats receive various sensory inputs, including insect echoes, clutter echoes, and pulses and echoes from other bats, which must create a complex acoustic situation. Here, we discuss how bats extract own faint echoes in the presence of noise, by focusing on three similar but different situations; auditory masking, clutter interference, and jamming. Sensitivity to faint echoes is maintained after intense pulse emission, by contraction of middle ear muscles during emission. Echoes from off-axis objects could be “defocused” by comparing spectral features in the pulses and echoes. In the presence of conspecifics, bats increase the intensity and duration of pulses to improve the signal-to-noise ratio of their own echoes. They also regulate spectrotemporal features of pulses to separate their own echoes from sounds of conspecifics. Some of the adaptations made by bats may have future engineering applications for radar or sonar systems.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126740649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Body ownership in humans is sometimes extended to certain external objects apart from our own bodies, and such plastic changes in body ownership are thought to be the basis of tool use. Specifically, in a rubber hand illusion task, visuotactile stimuli from synchronous brush strokes to both participants’ and rubber hands lead to illusory body ownership of the rubber hand and a shift of perception of the tactile stimuli to the rubber hand as a result of multisensory integration. Recent studies suggest that this kind of body ownership illusion occurs not only in humans but also in animals, including monkeys and mice. In addition, other studies have shown that body ownership is linked to empathy. Studying the body ownership illusion in humans and other animals, including models of human psychiatric disorders, will elucidate neural mechanisms underlying the sense of body ownership, which will consequently contribute to addressing the philosophical issue of self-awareness.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117226840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122012325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
