Henrike Moll: USCHumans are an extraordinarily social species. Their unique way of relating to one another becomes evident very early in ontogeny. In this talk, I will present two lines of experiments, both of which exemplify toddlers’ attunement to other persons and their awareness of others’ perceptual and epistemic states. In one line of experiments, […]

David Funder: UC RiversideBehavior is a function of the person and the situation, and understanding the "personality triad" of persons, situations and behaviors requires assessment instruments for all three. However, until recently tools for assessing situations were not available. The Riverside Situational Q-sort (RSQ) was developed to fill this gap, and has been applied in […]

Federico Rossano: Max Plank InstituteSocial theorists as diverse as Locke, Hume, Rousseau, and Marx have suggested that without the institution of property modern civil society would not exist. All human societies care about ownership of at least some kinds of things (Brown, 1991; Hann, 1998), yet young children struggle to understand property and come only […]

Corina Logan: UCSBNew Caledonian crows are one of the few species that make and use tools in the wild. Tool types differ across their range in an overlapping pattern, suggesting that tool designs are copied with a high fidelity and may be transmitted across generations, thus allowing for cumulative changes to occur to the lineage […]

Ben Trumble: UCSBIn February 2014, catastrophic flooding impacted the Tsimane forager-horticulturalists of lowland Bolivia. Flooding decimated the subsistence lifestyle and more than two-thirds of villages were flooded (completely destroying crops and washing away most possessions); thousands fled to the nearby market town of San Borja. Widespread food insecurity and disease followed. This project examines the […]

Eduardo Fernandez-Duque: Yale UniversityI will discuss published and new data from a population of monogamous owl monkeys in the Argentinean Chaco that we have been studying for almost 20 years to examine the hypothesis that social monogamy is a default social system imposed upon males because the spatial and/or temporal distribution of resources and females […]

John Tooby: UCSBDon’t shoot! Rodney King. Remember the Maine. The Reichstag Fire. Guernica. The War of Jenkins Ear. The murder of Emmet Till. Events in which one or more members of one group injure the welfare of one or more members of another group (“outrages”) typically provoke extraordinarily strong and frequently violent responses directed more […]

Robert Provine: University of MarylandAfter an introduction to the nature and use of laughter in daily life, discussion turns to the evolution of laughter and its implications for the emergence of speech. Contrasts between human and chimpanzee laughter reveal that laughter is the ritualized signal of labored breathing of rough-and-tumble, with the vocalization representing the […]

No BEC This Week:

Meg Crofoot: UC DavisAnimals living in stable social groups may often disagree about where to go, but must reconcile their differences to maintain cohesion and thus the benefits of group living. Although theory predicts that shared (democratic) decision-making should be widespread in nature, in species that form long-term social bonds, considerable asymmetries in dominance and […]
