The view that episodic memory and metacognition are human-unique abilities has been challenged over the recent decades. 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.

Planning, or an internal process of making decisions about one's future behavior, appears advantageous not only for humans but also for non-human species. In fact, recent studies have shown that many non-human primates as well as some avian species may be endowed with planning capacities. Those animals are suggested to plan in order to meet not only present but also future needs, as opposed to the Bischof-Köhler hypothesis. Testing planning in a wider variety of species using various setups would be required to uncover phylogenetic and ecological factors that may have facilitated evolution of planning. In particular, it is important to examine planning abilities by using general learning tasks instead of species-specific situations such as tool-use and food-caching. After reviewing evidence on planning by non-human animals, we introduce recent findings about planning by pigeons in operant tasks including computerized navigation and maze tasks. Planning capacities may be shared across species from wider-ranging taxa than have been assumed. Metacognition of planning would serve as one of the most important topics for the future quest.

Eyeblink conditioning is an associative learning paradigm in which an association is formed by the paired presentation of a neutral conditioned stimulus (CS), such as a tone, and an unconditioned stimulus (US), such as a corneal air puff or a periorbital shock. In the rabbit, cerebellum-brainstem circuitry plays an essential role in delay eyeblink conditioning, in which the US is delayed and terminates simultaneously with the CS. However, the neural mechanisms underlying delay eyeblink conditioning in mice and rats are unclear. In addition to cerebellum-brainstem circuitry, the amygdala is reportedly important for delay eyeblink conditioning in the mouse and rat. Here, we review the neural mechanisms underlying delay eyeblink conditioning in the rabbit, mouse, and rat, discussing relevant neural circuitry specific to mice and rats versus rabbits. We also review the neural circuitry underlying trace eyeblink conditioning, in which the CS and US are separated by a stimulus-free trace interval. The forebrain and cerebellar-brainstem circuitries are important for trace eyeblink conditioning in the rabbit, mouse, and rat. This review provides useful information for future research on eyeblink conditioning and for understanding neural substrates subserving learning and memory.

<p>Non-human animals commonly perform mutual communication in which two individuals simultaneously exchange information in an interaction that can comprise multiple components and multimodal signals. The forms of mutual communication vary widely, ranging from simple greeting ceremonies to complex paired dances including ultiple behavioural elements. Our understanding of mutual communication lags markedly because few systematic studies have examined this topic. In this review, we used the example of paired dances in red-crowned cranes (<i>Grus japonensis</i>) to examine two important aspects of mutual communication: structure and function. We reviewed the difficulty analysing the key characteristics of structure quantitatively (e.g. sequential pattern and complexity), and examined suitable analytic methods such as etermining the four levels of its characteristics. We proposed that a combination of current methods and new methods, such as the Shannon entropy index and temporal associations among behavioural elements, is necessary to quantify the complexity of mutual communication. Regarding the function of paired dances, we critically discuss the pair bond hypothesis, which suggests that a paired dance strengthens pair bonds in monogamous, long-living birds. Testing this classical hypothesis remains a challenge due to the difficulty of performing quantitative analyses of paired dances and the ambiguous concept of pair bonds. We hope that the questions and predictions raised in this paper will encourage future research on mutual communication in non-human animals.</p>

This paper aims to reflect the 30 years of Ai project that started in 1978. Ai project started as a sort of ape-language project. However, it was uniquely different from the previous studies in terms of the computer-interfaced system and the introduction of psychophysical measurement. The original version of Ai project may be summarized as an attempt to know the perceptual world of a nonhuman animal. It combined the psychological studies on learning and perception and utilized the language-like skill as a window through which we can access to the chimpanzee mind. This paper put the Ai project in a historical context, summed up the research results, showed the fieldwork on the wild chimpanzees, and illuminated the establishment and the perspective of a new discipline named Comparative Cognitive Science.

As you prepare an English presentation, your main focus should be on getting your message across to the audience effectively. Even if you do not have native-like proficiency in English, there are many other ways to make your presentation appealing. These include learning and practicing pronunciation of keywords, adopting spoken language rather than written language for your speech, increasing the readability of your slides by reducing the amount of words on them, developing a relationship with the audience, and providing variation to keep the audience attentive. It should also be noted that language and presentation style have changed over the years and will continue to change.

The effects of male parents on later parental behavior of their pups were investigated in ICR mice. Male parents were vasectomized to prevent female parents from giving birth to the second litter before weaning of the first one. The subjects were reared by a female parent alone or by both parents until 30 days old. When they were exposed to stimulus pups at 10-11 weeks of age (Exp. 1), their parental behaviors didn't differ from each other for their rearing conditions. However, when they were tested after experiencing copulation (Exp. 2), nest-building significantly decreased in the females reared by both parents. These results suggest that in mice the effects of cohabitation with a male parent in the early rearing environment on parental behavior were modifiable by the experience of copulation, but such effects were largely limited.

This article describes background information for the symposium held at the 70th Annual meeting of the Japanese Society for Animal Psychology. The main theme of this symposium was to provide updated information on neurodevelopmental toxicity caused by environmental chemicals, through lectures by three distinguished researchers, and to discuss possible contributions and expected roles of animal psychology in toxicological studies designed to protect children's health. The Ministry of the Environment has commenced a large-scale, long-term epidemiological study entitled the “Environment and Children's Study (Eco-Chil)”, to elucidate health effects caused by chemical exposures of children including pervasive developmental disorders. Neurobehavioral assessments have been included in globally accepted guidelines for neurotoxicity and reproductive toxicity studies in rodents as effective tools for collecting experimental evidence. Findings from these experiments provide a scientific basis for the epidemiological studies, like Eco-Chil. However, currently available behavioral testing methods are insufficient for detecting neurodevelopmental effects of environmental chemicals, especially for emotionality and social aspects of behavior. Appropriate animal behavioral models are needed to advance toxicological studies further. Animal psychologists could greatly contribute to the development of these animal models and the interpretation of behavioral test results.

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.

Understanding maternal behavior and infant development of wild animals living in modern zoos is essential for zoos to achieve conservation which is one of their primary roles, including successful reproduction in captivity. Moreover, zoos could provide us with the opportunities to understand the diversity of mother-infant relationships among mammals. For example, like those in the wild, giraffe and black rhinoceros mothers in captivity show hider and follower types, respectively. Moreover, our detailed observations at zoos have shown that giraffe mothers tend to be very responsible for nursing interactions with their calves, whereas rhinoceros mothers have tolerant attitudes toward their calves. Unlike ungulates, infants of primates such as Japanese monkeys and gorillas spend most of their time in contact with their mothers during the early stages of development owing to their clinging abilities, which decrease with increasing infant age. Seeing zoo animals directly as well as learning of their behavior, based on behavioral studies on them would help zoo visitors develop an interest in zoo animals and their counterparts in the wild.

Great apes have prolonged dependent period and learn a variety of skills and knowledge through intensive interaction with the mother based on affectionate bond between them. Among four species of great apes, both chimpanzees and orangutans use tools in the wild based on their skills of object manipulation and cognitive development which is gradually formed through mother-infant interactions. Researchers found the effectiveness of human intervention and support to promote mother-rearing in captive great apes despite of initial maternal problems. Compared to African great apes, orangutans have solitary lifestyle and the longest dependent period of about 7-8 years indicating the higher reliance on the other. Orang Utan Island (OUI) is a facility open to public and located in Bukit Merah, Perak, Peninsula Malaysia. OUI holds 26 orangutans and has been promoting rehabilitation program as an effort of ex-situ conservation. Orangutan mothers are now practicing infant rearing in OUI and in semi-natural environment in adjacent BJ Island. The importance of mother-infant interaction as a base for cognitive development should be widely recognized among animal researchers and keepers for promoting mother-rearing in captive settings.

Both positivity and negativity are important components for the development of mother-offspring relationship. The "inter-body antagonism" is an important biological framework to promote offspring's independence from mothers. Weaning, an achievement of nutritional independence in offspring, is a typical situation in which mother-child negativity plays an important role. Human mother-child separation is also actualized by complex sociocultural allomothering systems consisting of objects, persons and institutes. Human triadic relationship in joint attention by mother and infant to object is a basic element of the systems. The relationship is preceded by "Proto-triadic relationship" in which particular body parts are used as targets in human inter-body interactions as in a case of tickling play.Not only object but also person could be a target of attention in triadic relation, and exchange of perspectives with the person is essential in the human infant's cultural learning and establishment of social network. A special allomothering by a girl called Moriane in an island of Okinawa is an example of such allomothering.
