Language is culturally transmitted. Iterated learning, the process by which the output of one individual's learning becomes the input to other individuals' learning, provides a framework for investigating the cultural evolution of linguistic structure. We present two models, based upon the iterated learning framework, which show that the poverty of the stimulus available to language learners le...

The emerging emphasis on disaster risk reduction has broadened the range of experts whose knowledge must be garnered to resolve complex socio-technical challenges. This paper examines the role and position of the construction sector for addressing these concerns. Specifically, it examines the recursive nature of practices within the built environment, which can be seen as deeply ingraining frag...

Three studies investigated whether apologies and/or thanks in a favor asking email message increase normality of the message, positive attitude about the message, sender credibility and willingness to give the favor in the U.S. and Korea. Participants as the Sender in study 1 (N = 521) and as the Receiver in study 2 (N = 386) completed one of four versions of a questionnaire regarding a prototy...

We review the current state of agricultural systems science, focusing in particular on the capabilities and limitations of agricultural systems models. We discuss the state of models relative to five different Use Cases spanning field, farm, landscape, regional, and global spatial scales and engaging questions in past, current, and future time periods. Contributions from multiple disciplines ha...

Reconstructing the rise and fall of social complexity in human societies through time is fundamental for understanding some of the most important transformations in human history. Phylogenetic methods based on language diversity provide a means to reconstruct pre-historic events and model the transition rates of cultural change through time. We model and compare the evolution of social complexi...

Cross-cultural comparison is a critical method by which we can examine the interaction between culture and psychological processes. However, comparative methods tend to overlook cultural dynamics - the formation, maintenance, and transformation of cultures over time. The present article gives a brief overview of four different types of research designs that have been used to examine cultural dy...

Even though there is no agreed definition of what constitutes an ethnic group, there are a number of features that most academic treatments of the subject attribute to such groups: a proper collective name, shared myths of origin, and cultural characteristics, such as language, religion, traditions and customs that distinguish a given group from others. Different combinations of these features ...

In this paper, I argue that the adaptive fit between human cultures and their environment is persuasive evidence that some form of evolutionary mechanism has been important in driving human cultural change. I distinguish three mechanisms of cultural evolution: niche construction leading to cultural group selection; the vertical flow of cultural information from parents to their children, and th...

Culture pervades human life and is at the origin of the success of our species. A wide range of other animals have culture too, but often in a limited form that does not complexify through the gradual accumulation of innovations. We developed a new paradigm to study cultural evolution in primates in order to better evaluate our closest relatives' cultural capacities. Previous studies using tran...
