Abstract: While widely acknowledged in the cultural evolution literature, ecological factors—aspects of the physical environment that affect the way in which cultural productions evolve—have not been investigated experimentally. Here, we present an experimental investigation of this type of factor by using a transmission chain (iterated learning) experiment. We predicted that differences in the distance between identical tools (drums) and in the order in which they are to be used would cause the evolution of different rhythms…
Abstract: The spatial composition of human portraits obeys historically changing cultural norms. We show that it is also affected by cognitive factors that cause greater spontaneous attention to what is in front rather in the back of an agent. Scenes with more space in front of a directed object are both more often produced and judged as more aesthetically pleasant. This leads to the prediction that, in profile-oriented human portraits, compositions with more space in front of depicted agents (a “forward bias”) should be over-represented. …
Abstract: Standard dual process theories see reason (System 2) as an individual cognitive mechanism able to correct the mistake of intuition (System 1) and to perform as classical rational system, imperfect but not bounded in Simon’s sense. This chapter suggests instead that reason is another intuitive cognitive mechanism, with a specific domain—reasons—and specific functions—to produce and evaluate justifications and arguments in social settings…
Abstract: We investigated whether communicative cues help observers to make sense of human interaction. We recorded EEG from an observer monitoring two individuals who were occasionally communicating with each other via either mutual eye contact and/or pointing gestures, and then jointly attending to the same object or attending to different objects that were placed on a table in front of them. The analyses were focussed on the processing of the interaction outcome (i.e. presence or absence of joint attention) and showed that its interpretation is a two-stage process, as reflected in the N300 and the N400 potentials…
“The editors of the volume asked me to provide a broad overview of the beginnings of relevance theory back in the 1970s, how it has developed over the decades and where I see it moving in the future, reflecting in the process on the collective work that Deirdre Wilson and I initiated and that has been joined and considerably enriched by many others. Here are some personal notes to help address these questions…”
Abstract: I argue, with examples, that most human cognitive skills are neither instincts nor gadgets but mechanisms shaped both by evolved dispositions and by cultural inputs. This shaping can work either through evolved skills fulfilling their function with the help of cultural skills that they contribute to shape, or through cultural skills recruiting evolved skills and adjusting to them.

Abstract: In their reviews [of The Enigma of Reason], Chater and Oaksford, Dutilh Novaes, and Sterelny are critical of our modularist approach to reason. In this response, we clarify our claim that reason is one of many cognitive modules that produce intuitive inferences each in its domain; the reason module producing intuitions about reasons. We argue that in-principle objections to the idea of massive modularity based on Fodor’s peculiar approach are not effective against other interpretations that have led to insightful uses of the notion in psychology and biology. We explain how the reason module evaluates reasons on the basis of their metacognitive properties. We show how the module fulfils a social function, that of producing reasons to justify oneself and convince others and of evaluating the reasons others produce to convince us.
