Humans are ultra-social: they spontaneously incorporate others’ mental states into their action-planning (Kaminski et al.,2008), and altercentric: their behavior is influenced by others’ perspectives, even perspectives irrelevant to their instrumental goal (Kampis &amp; Southgate, 2020). Recent evidence suggests that similarly to human infants, non-human great apes anticipate others’ actions based on their beliefs (Krupenye et al.,2016; Kano et al, 2019); raising the critical question whether altercentrism is uniquely human. 
In two experiments, we tested chimpanzees, bonobos, and orangutans in a manual search paradigm adapted from Mendes et al. (2008). These experiments replicated findings demonstrating apes’ first-person object-tracking abilities. Experiment 1 found no evidence for altercentrism: apes’ search behavior was not spontaneously modulated by another agent’s beliefs (unlike 14-month-old human infants; Kampis &amp; Kovács, 2020). Experiment 2 found tentative evidence that apes inferred a person’s actions based on her beliefs, and adapted their own actions based on this information.

This paper studies social interaction in newborns and of various species, whose behavioral developments attributed to the circular sensory motor Stage 3 of behavior development. The article has associated 16 exciting facts of the social behavior in groups of different species, highlighting three questions: (1) how can newborns successfully classify social phenomena that are abstract or absent from their reality; (2) whether emotional contagion can appear through cues of body language that subjects cannot consciously perceive; (3) how do organisms distinguish identical stimuli by their importance (value) without perceptual driver stimuli. The analysis suggests that organisms can interact at initial stages of development by distinguishing cues of a similar modality by their significance (their value). This ability contributes to the assimilation of knowledge about the initial social phenomena. This paper proposes the model of Coherent intelligence, which is strictly based on experimental evidence in modern literature and laws of physics.

Common Origins of Social Interaction of Different Species: The Model of Coherent Intelligence Linking Physics to Social Sciences

Domain-general thought requires an ability to combine information from different cognitive domains within a single judgement. We presented kea parrots (Nestor notabilis) with probabilistic choice tasks that required them to make predictions about which of two hidden samples was most likely to contain a rewarding token. Over the course of three experiments, we found that kea used relative rather than absolute quantities to make their sampling predictions and could integrate either knowledge about a physical barrier or demonstrators’ sampling biases to adjust their judgements. This work provides the first evidence for domain-general statistical inference outside of humans and the great apes. This suggests that at least two structurally distinct brain models have independently evolved an ability to integrate information, highlighting how comparative cognition may inspire the development of novel artificial general intelligence systems.

Male spotted bowerbirds perform vigorous courtship dances to visiting females on elaborate display arenas. Each arena is built and defended by one dominant male, which commonly tolerates one or more subordinate males. These non-territorial “auxiliary” males are thought to be inexperienced sub-adults. The skills hypothesis suggests that auxiliaries attend established bowers to practice their courtship skills, but little is known about the development of courtship motor performance and which courtship properties are refined with experience. Here we investigate whether auxiliaries are as proficient as bower owners in performing courtship. First, we investigate whether specific courtship moves are used in different contexts within a courtship routine and whether such flexible use of courtship elements is shared both by bower owners and auxiliaries. Second, we examine other fine-scale parameters of courtship dances, in order to further test for possible differences in courtship properties depending on dominance status.

This paper reviews the existing literature on categorical perception of sounds and colors in different animals including humans. We highlight that categorical perception is a combination of nature and nurture; to be specific, categorical perception is innate with a phylogenetic root, but it can also be modified by postnatal experience. We also suggest that language is not wholly the basis for categorical perception, as what Sapir-Whorf hypothesis posits; instead, language is one type of experience that can affect the nurture part of categorical perception across domains and modalities in humans.

Categorical Perception as a Combination of Nature and Nurture

The usual approach to studying affordances is in controlled laboratory situations. While recognizing the value of controlled experimentation, I argue for the benefits of additionally considering affordances “in the wild,” i.e., in the context of real-world activity. As an example, I describe ethnographic observation about the introduction of cellphones in rural Uganda in the early 2000s, highlighting the unexpected, innovative uses that emerged in that unique context. This case, I suggest, illustrates the constitutive role of material, sociocultural constraints in the perception and realization of affordances which often go unacknowledged in experimental laboratory research. Theoretically, the case raises questions about the definition of affordances, in particular how narrowly or broadly to conceptualize their spatiotemporal dimensionality. And methodologically, it poses the question of how anthropology can contribute to embodied cognitive science and, more broadly, how experimental and observational approaches can help one another to further our understanding of psychological phenomena.

Affordances in the wild: Anthropological Contributions to Embodied Cognitive Science

Although orangutans are closely related to humans, very little is known about their ontogenetic development. In particular, there is a lack of systematic research on the maternal behaviors that mediate skill development in early infancy. To address this topic, we conducted a longitudinal study in which a Sumatran orangutan (Pongo abelii) mother-infant dyad was systematically observed across 28 months, starting with the infant’s birth. Our data revealed several classes of maternal behavior that potentially influenced infant skill development. The timing of these behaviors was contingent upon infant competence level, as active interventions were intense during periods of skill acquisition. The same behaviors were flexibly deployed independent of whether the infant was in the process of acquiring foraging, locomotor or social skills. Our findings suggest that the maternal behaviors that mediate infant skill development in Sumatran orangutans have features reminiscent of human scaffolding, and raise questions about intentionality in such behaviors.

Sensory stimuli can mediate cognition and behavior in different ways. In humans, chemosensory threat cues enhance performance and increase vigilance. In non-human primates, visual, olfactory and even tactile cues of biological contaminants elicit avoidance behaviors, i.e. manifestations of the adaptive system of disgust in humans. Nevertheless, how contaminant sensory cues may affect cognitive processes in non-human primates remains largely unexplored. We tested how visual cues suggesting pathogen presence may affect cognitive performance in chimpanzees. We used disgust-related images displayed at regular intervals during a number ordering task on touch screens. Images of carcasses provoked more errors following their display compared to control and other condition images (i.e. invertebrates and food). Our results support the hypothesis that visual disgust elicitors decrease performance by distracting individuals. Future studies should determine whether cognitive responses evolved differently across threat contexts (fear vs. disgust) given their differences in outcomes (death vs. disease).

Humans are uniquely impressive cooperators, and yet it remains unclear exactly which cognitive and motivational mechanisms set human cooperation apart. Our closest relatives, bonobos and chimpanzees, have also demonstrated a range of prosocial tendencies across experimental and observational contexts. Critically, however, we do not yet know whether their helping behavior, like that of humans, is motivated by an acute sensitivity to others’ needs. We investigated this question in a novel eye-tracking task, with a large sample of captive apes. While their gaze and pupils were tracked, apes viewed controlled videos of an agent reaching toward objects that ultimately would or would not be attainable without help. If apes are acutely sensitive to others’ needs, we predicted that they would show greater pupil dilation (arousal) when the agent could not complete a goal on his own. Our findings shed light on the mechanistic and evolutionary bases of human prosociality and empathy.

The ability to learn temporal relationships and use that knowledge to simulate future events is among the most remarkable aspects of cognition. Recently introduced behavioral task called Judgment of Imminence (JOI) combined with a well-known Judgment of Recency (JOR) task pointed to a remarkable symmetry between the temporal organization of memory and prediction. The data were consistent with the hypothesis that both memory and prediction can be organized as a compressed mental timeline. This means that the past and future can be remembered or simulated sequentially relative to the present. The compression implies that events closer to the present, regardless of whether they are in the past or in the future, were represented more accurately than those further from the present. Here we used the existing JOR model based on a compressed memory timeline to build an associative representation that can learn the temporal relationships and create a timeline of the future, which mirrors the timeline of the past. We show that this approach can simultaneously account for response times and accuracy in both JOR and JOI. This work provides a time-local neural-level mechanistic account for how the temporal organization of the memory can be used to learn the temporal structure of the world and simulate the future in an efficient manner as a compressed mental timeline.

It was assumed that the duration of working memory in dogs is around 27 seconds, however, a study on a group of dogs revealed that they were able to maintain spatial memory of an object up to 240 seconds. In our study, we looked at 50 multiple dog breeds. In experiment 1, a small ball was put in one of the 3 wooden boxes in front of the dogs. The dogs had a retention interval for 1,2,3 and 4 minutes consecutively. Then they were asked to search for the ball. In experiment 2, the same ball was put in 3 colourful boxes that were, green, blue, and purple which are distinguishable to dog vision. The retention intervals were kept the same. Our results revealed that the addition of colour has increased the dogs' likelihood of finding the ball which suggests an advancement in the duration of working memory.
