Animals use multiple strategies for spatial navigation rather than a single strategy and flexibly choose an appropriate strategy in accordance with each environmental condition. Concerning the goal searching in humans, for example, whether it is based on information from multiple landmarks or from just one landmark would depend on the salience of the landmarks. Our conclusion is that it is more important what strategies or spatial information animals choose under what conditions than whether or not they have and use the strategies.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128211288","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}

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.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125954026","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}

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.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116172685","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}

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.

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.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114761484","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}

While much of the focus of nonhuman studies has been on primates, western scrub-jays contributed extensively towards the understanding of these abilities. Western scrub-jays demonstrate episodic-like memory by remembering what, where, and when they cached food items and by using this information flexibly during recovery to change their behaviour according to the situation. In addition to episodic-like memory, recent studies suggest that these birds are also capable of self-reflection in a form of metacognition. Further investigation of their self-reflective ability may be the critical approach in deepening our understanding of episodic memory in nonhuman animals.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116519500","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}

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.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127306077","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}

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.","PeriodicalId":260786,"journal":{"name":"Japanese Journal of Animal Psychology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123425200","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}
