I am interested in comparing the cognitive abilities of primates to those of species in other taxa. More specifically, I aim to understand the ecological pressures that may have driven the evolution of specific cognitive mechanisms in different mammalian species. Further, I intend to study whether these cognitive abilities are domain-specific or if they can be generalized across different contexts. For example, meerkats (Suricata suricatta) have been show to teach their offspring how to handle highly mobile prey items. However, it is unclear whether teaching in this species is constrained to the foraging domain or if meerkats also transmit other kinds of information through teaching. To address these questions I will study cotton-top tamarins (Saguinus oedipus), a cooperatively breeding primate and meerkats, a cooperatively breeding social carnivore. I hope that this work will place our understanding of animal cognitive evolution in a broader mammalian context.

I am interested in the developmental and evolutionary origins of the human music capacity. My research is driven by the general questions of domain-specificity, innateness, and uniqueness of music-- Why is music a fundamental and universal part of human nature, and yet absent in other primate species? I aim to address these questions via research on early human development and via comparative research with non-human primates. Current questions of interest include: Why does music evoke emotional/physiological response, and to what extent do other animals experience similar responses to music? What is the role of infant-directed song and infant-directed speech in early development, and how does IDS mediate attention and learning? What computational mechanisms underlie music processing, and to what extent are these mechanisms also used for processing input from other domains, such as language?

My main interest is the evolution of computational abilities in different species and the connection of these abilities to language. At the Cognitive Evolution Laboratory at Harvard I'm involved in experiments designed to assess these issues using spontaneous methods and conditioned learned procedures in both cotton-top tamarins and European starlings. At the Animal Cognition Laboratory, University of Trieste I am investigating similar capabilities in newly-hatched chicks through imprinting procedures. I am also involved in research concerning welfare, memory and laterality in sheep.

Spatial Cognition and Geometry

(email): lee@wjh.harvard.edu

How are spatial concepts organized in the mind? Are some concepts more
fundamentally rooted than others? For example, if presented with various types of
geometric cues in the same task, will human babies and non-human animals
spontaneously encode and use some more adeptly than others? The first goal of my
research is to explore whether we have evolved mechanisms designed to compute
specific geometric properties of specific types of environmental stimuli, and to
compare these sensitivities across various species in various tasks.

Although we do see striking similarities between human infants and nonhuman animals, over the course of
development humans come to look at the world in a geometric sense that transcends the limitations of our fundamental
capacities. What enables humans to build abstract geometric concepts from the core cognitive building blocks that we
share with other animals? What is the developmental timeline of this change, and what, if any, learning is required for
it to occur? The second goal of my research is to look for the crucial cognitive differences across species and age-groups (e.g., in symbolic or linguistic capacities) that might explain the uniquely-human concepts of Euclidean geometry.

I study whether the foundational mechanisms of two human abilities, numerical cognition and morality, represent forms of uniquely human knowledge, or whether some of the core systems that subserve these domains are evolutionarily ancient, and thus shared with other animals. In order to address these questions, I study three different populations: human infants, semi-free ranging rhesus macaques, and captive cotton-top tamarins and marmosets. Regarding number, I am interested in the question of what constitutes an individual to human infants and primates (object, sounds, actions, etc.), and whether the same computations can be performed over all three of these entities. Regarding morality, I am interested in whether the basic mechanisms that support a full-fledged moral system, such as representing animate vs. inanimate entities and attributing goals and beliefs to others, are present in our evolutionary history. In all of these studies, I attempt to minimize the methodological differences in testing primates and human infants; in this way, it becomes possible to investigate which domains of knowledge are uniquely human, and which core systems are shared with other animals.

Having studied moral philosophy as an undergraduate, I now aim to investigate the psychology of moral decision-making. I am interested in the cognitive mechanism underlying our moral judgments or moral intuitions. I hope to uncover the parameters of moral scenarios relevant to our judgments by comparing a large sample of normal subjects tested via the Internet at http://moral.wjh.Harvard.edu to patient populations, including autistics, who lack an understanding of intentionality, and patients with frontal lobe damage, who exhibit deficits in emotional
processing

Humans possess concepts of property and ownership that are unique among animals. My research investigates both the ontongeny and evolutionary origins of these concepts. Using developmental models I assess what cues children use to recognize and respect claims on objects. I am currently developing comparative paradigms to determine the mechanisms underlying similar behaviors in non-human primates. My work draws on insights from both child development and evolutionary theory to generate new hypotheses and create a more integrated understanding of proprietary behavior.
