Developmental shifts in social Cognition: socio-emotional biases across the lifespan in rhesus monkeys
Behavioral Ecology and Sociobiology, 2018Co-Authors: Alexandra G. Rosati, Michael L. Platt, Alyssa M. Arre, Laurie R. SantosAbstract:Humans exhibit a suite of developmental changes in social Cognition across the lifespan. To what extent are these developmental patterns unique? We first review several social domains in which humans undergo critical ontogenetic changes in socio-cognitive processing, including social attention and theory of mind. We then examine whether one human developmental transition—a shift in socio-emotional preferences—also occurs in non-human Primates. Specifically, we experimentally measured socio-emotional processing in a large population of rhesus macaques ( Macaca mulatta ) ranging from infancy to old age. We tested whether macaques, like humans, also exhibited developmental shifts from a negativity bias at younger ages, indicating preferential attention to negative socio-emotional stimuli, to a positivity bias at older ages. We first assessed monkeys’ ( n = 337) responses to negative socio-emotional stimuli by comparing their duration of looking towards photos of negative conspecific signals (threat displays) versus matched neutral expressions. In contrast to the pattern observed in humans, we found that older monkeys were more attentive to negative emotional stimuli than were younger monkeys. In a second study, we used the same method to examine monkeys’ ( n = 132) attention to positive (affiliative displays) versus matched neutral expressions. Monkeys did not exhibit an overall preference for positive stimuli, nor major age-related changes in their attention. These results indicate that while monkeys show robust ontogenetic shifts in social preferences, they differ from humans by exhibiting an increasing negativity bias with age. Studies of comparative cognitive development can therefore provide insight into the evolutionary origins of human socio-cognitive development. Significance statement Humans are characterized by complex and flexible social behavior. Understanding the proximate psychological mechanisms and developmental processes that underpin these social behaviors can shed light on the evolutionary history of our species. We used a comparative developmental approach to identify whether a key component of human social Cognition, responses to emotionally-charged social stimuli, are shared with other Primates. Humans exhibit important shifts in this aspect of our social Cognition: younger individuals attend more to negative stimuli, whereas older adults tend to focus on positive information. These shifts are thought to appropriately tailor our age-dependent social goals. We found that, unlike humans, rhesus monkeys show an increasing negativity bias with age. By examining Primate Cognition across the lifespan, this work can help disentangle how complex forms of social behavior emerge across species.

Comparative developmental psychology: how is human cognitive development unique?
Evolutionary psychology : an international journal of evolutionary approaches to psychology and behavior, 2014Co-Authors: Alexandra G. Rosati, Victoria Wobber, Kelly D. Hughes, Laurie R. SantosAbstract:The fields of developmental and comparative psychology both seek to illuminate the roots of adult cognitive systems. Developmental studies target the emergence of adult cognitive systems over ontogenetic time, whereas comparative studies investigate the origins of human Cognition in our evolutionary history. Despite the long tradition of research in both of these areas, little work has examined the intersection of the two: the study of cognitive development in a comparative perspective. In the current article, we review recent work using this comparative developmental approach to study non-human Primate Cognition. We argue that comparative data on the pace and pattern of cognitive development across species can address major theoretical questions in both psychology and biology. In particular, such integrative research will allow stronger biological inferences about the function of developmental change, and will be critical in addressing how humans come to acquire species-unique cognitive abilities.

Evolutionary Anthropological Insights into Neuroeconomics: What Non-Human Primates can Tell us About Human Decision-Making Strategies
Neuroeconomics, 2014Co-Authors: Laurie R. Santos, Michael L. PlattAbstract:In this chapter we discuss why behavioral studies of irrational biases in non-human Primates are important for the field of neuroeconomics. We begin with a review of how behavioral work on choice biases in monkeys is important for understanding the nature of human choice errors. We then provide an introduction to the Primate Cognition approach, including a short overview of the organization of the Primate order. We then briefly review the ecology and Cognition of two Primate species standardly used as models of human irrational decision making — brown capuchins and rhesus macaques. We next discuss empirical studies demonstrating that monkeys show human-like irrational errors in three of the classic situations in which human participants fall prey to biases: monkeys exhibit framing effects in risky decisions, they show endowment effects, and they are averse to ambiguous outcomes. We conclude our chapter with a discussion of how future work in neuroeconomics can capitalize on these new behavioral findings in monkeys.

The thinking ape: The enigma of human consciousness
Annals of the New York Academy of Sciences, 2013Co-Authors: Steve Paulson, Laurie R. Santos, David J. Chalmers, Daniel Kahneman, Nicholas D. SchiffAbstract:What is the origin and nature of consciousness? If consciousness is common to humans and animals alike, what are the defining traits of human consciousness? Moderated by Steve Paulson, executive producer and host of To the Best of Our Knowledge, Nobel laureate psychologist Daniel Kahneman, philosopher David Chalmers, expert in Primate Cognition Laurie Santos, and physician-scientist Nicholas Schiff discuss what it means to be conscious and examine the human capacities displayed in cognitive, aesthetic, and ethical behaviors, with a focus on the place and function of the mind within nature. The following is an edited transcript of the discussion that occurred October 10, 2012, 7:00-8:15 PM, at the New York Academy of Sciences in New York City.

Logical inferences from visual and auditory information in ruffed lemurs and sifakas
Animal Behaviour, 2020Co-Authors: Francesca De Petrillo, Alexandra G. RosatiAbstract:Inference by exclusion, or the ability to select a correct course of action by systematically excluding other potential alternatives, is a form of logical inference that allows individuals to solve problems without complete information. Current comparative research shows that several bird, mammal and Primate species can find hidden food through inference by exclusion. Yet there is also wide variation in how successful different species are as well as the kinds of sensory information they can use to do so. An important question is therefore why some species are better at engaging in logical inference than others. Here, we investigate the evolution of logical reasoning abilities by comparing strepsirrhine Primate species that vary in dietary ecology: frugivorous ruffed lemurs (Varecia spp.) and folivorous Coquerel's sifakas, Propithecus coquereli. Across two studies, we examined their abilities to locate food using direct information versus inference from exclusion and using both visual and auditory information. In study 1, we assessed whether these lemurs could make inferences when full visual and auditory information about the two potential locations of food were provided. In study 2, we then compared their ability to make direct inferences versus inferences by exclusion in both the visual and auditory domains. We found that these lemur species can use visual information to find food, but that only ruffed lemurs were also able to use auditory cues, mirroring differences in the complexity of their wild ecology. We further found that, unlike many anthropoid species tested to date, these strepsirrhine species failed to make inferences by exclusion. These results highlight the importance of natural history in understanding the evolution of logical inference and help reconstruct the deeper phylogeny of Primate Cognition.

Foraging Cognition: Reviving the Ecological Intelligence Hypothesis
Trends in cognitive sciences, 2017Co-Authors: Alexandra G. RosatiAbstract:What are the origins of intelligent behavior? The demands associated with living in complex social groups have been the favored explanation for the evolution of Primate Cognition in general and human Cognition in particular. However, recent comparative research indicates that ecological variation can also shape cognitive abilities. I synthesize the emerging evidence that ‘foraging Cognition' – skills used to exploit food resources, including spatial memory, decision-making, and inhibitory control – varies adaptively across Primates. These findings provide a new framework for the evolution of human Cognition, given our species' dependence on costly, high-value food resources. Understanding the origins of the human mind will require an integrative theory accounting for how humans are unique in both our sociality and our ecology.
