The weirdest people in the world?

In a forthcoming issue of Brain and Behavioral Sciences, anthropologist Joe Henrich, and psychologists Steven Heine, and Ara Norenzayan review the available database of comparative social and behavioral science studies (here are Science's and Nature's comments). They found that people from Western, educated, industrialized, rich and democratic (WEIRD) societies — who represent as much as 80 percent of study participants, but only 12 percent of the world’s population — are not only unrepresentative of humans as a species, but on many measures, they’re outliers.

A psychological theory of human tool use

An interesting and ambitious article by François Osiurak, Christophe Jarry,and Didier Le Gall: "Grasping the affordances, understanding the reasoning: toward a dialectical theory of human tool use" in Psychological Review, (2010 -117(2):517-40) freely available here.

Abstract: One of the most exciting issues in psychology is what are the psychological mechanisms underlying human tool use? The computational approach assumes that the use of a tool (e.g., a hammer) requires the extraction of sensory information about object properties (heavy, rigid), which can then be translated into appropriate motor outputs (grasping, hammering). The ecological approach suggests that we do not perceive the properties of tools per se but what they afford (a heavy, rigid object affords pounding). This is the theory of affordances. In this article, we examine the potential of the computational view and the ecological view to account for human tool use. To anticipate our conclusions, neither of these approaches is likely to be satisfactory, notably because of their incapacity to resolve the issue of why humans spontaneously use tools. In response, we offer an original theoretical framework based on the idea that affordance perception and technical reasoning work together in a
dialectical way. The thesis we defend here is that humans have the ability to view body action as a problem to be solved. And it is precisely at this point that technical reasoning occurs. But, even if the ability to do technical reasoning gives humans the illusion of constantly doing less (e.g., TV remote control), they are still forced to use body action – and to perceive affordances – to operate the product of the reasoning (pushing buttons with the fingers). This is the principle of dialectic.

The self in 'face' and 'dignity' cultures

Two interesting articles by Young-Hoon Kim and Dov Cohen: "Information, Perspective, and Judgement about the Self in Face and Dignity Cultures"  in Personality and Social Psychology Bulletin (2010 36: 537-550) here; and, with Wing-Tung Au: "The jury and abjury of my peers: The self in face and dignity cultures" in  the Journal of Personality and Social Psychology, (Vol 98(6), Jun 2010, 904-916) here. The latter begins:

"There are two ways to know the self: from the inside and from the outside. In all cultures, people know themselves from both directions. People make judgments about themselves from what they “know” about themselves, and they absorb the judgments of other people so that the judgments become their own. The process is one of constant flow, but there is variation, from both person to person and culture to culture, in which direction takes precedence. In this article, we outline the way face cultures tend to give priority to knowing oneself from the outside, whereas dignity cultures tend to give priority to knowing the self from the inside and may resist allowing the self to be defined by others. We first distinguish between face cultures and dignity cultures, describing the cultural logics of each and how these lead to distinctive ways in which the self is defined and constructed. We discuss the differing roles of public (vs. private) information in the two cultures, noting the way that such public information becomes absorbed into the definition of face culture participants and the way that it can become something to struggle against among dignity culture participants—even when it might reflect positively on the participant. Finally, we describe three cross-cultural experiments in which the phenomena is examined and then close with a discussion of the different ways our selves are “knotted” up with the judgments of other people."

Pinker on Mind and Media

In a New York Times  op-ed entitled "Mind over Mass Media", Steven Pinker (June, 10, 2010) challenges persistent clichés. It  begins:

"New forms of media have always caused moral panics: the printing press, newspapers, paperbacks and television were all once denounced as threats to their consumers’ brainpower and moral fiber. So too with electronic technologies. PowerPoint, we’re told, is reducing discourse to bullet points. Search engines lower our intelligence, encouraging us to skim on the surface of knowledge rather than dive to its depths. Twitter is shrinking our attention spans. But such panics often fail basic reality checks. When comic books were accused of turning juveniles into delinquents in the 1950s, crime was falling to record lows, just as the denunciations of video games in the 1990s coincided with the great American crime decline. The decades of television, transistor radios and rock videos were also decades in which I.Q. scores rose continuously." To read more...

A deflationary approach to economic games

Forthcoming in PNAS, an important paper by Rolf Kümmerli, Maxwell Burton-Chellew, Adin Ross-Gillespie and Stuart West: “Resistance to extreme strategies, rather thanprosocial preferences, can explain human cooperation in public goods games” (available here) that illustrates "why caution must be exercised when interpreting the evolutionary implications of economic experiments."

 Abstract: The results of numerous economic games suggest that humans behave more cooperatively than would be expected if they were maximizing selfish interests. It has been argued that this is because individuals gain satisfaction from the success of others, and that such prosocial preferences require a novel evolutionary explanation. However, in previous games, imperfect behavior would automatically lead to an increase in cooperation, making it impossible to decouple any form of mistake or error from prosocial cooperative decisions.

Overimitation in Kalahari Bushman: Children and the Origins of Human Cultural Cognition

An interesting paper by Mark Nielsen and Keyan Tomaselli “Overimitation in Kalahari Bushman Children and the Origins of Human Cultural Cognition” in Psychological Science,May 2010, 21: 729-736. You will find a freely available version here, and a short presentation of the research with a video at ScienceNow here


Abstract: Children are surrounded by objects that they must learn to use. One of the most efficient ways children do this is by imitation. Recent work has shown that, in contrast to nonhuman primates, human children focus more on reproducing the specific actions used than on achieving actual outcomes when learning by imitating. From 18 months of age, children will routinely copy even arbitrary and unnecessary actions. This puzzling behavior is called overimitation. By documenting similarities exhibited by children from a large, industrialized city and children from remote Bushman communities in southern Africa, we provide here the first indication that overimitation may be a universal human trait. We also show that overimitation is unaffected by the age of the child, differences in the testing environment, or familiarity with the demonstrating adult. Furthermore, we argue that, although seemingly maladaptive, overimitation reflects an evolutionary adaptation that is fundamental to the development and transmission of human culture.

Do not confound homophily and contagion!

At, a relevant paper by  Cosma Shalizi and Andrew C. Thomas “Homophily and Contagion Are Generically Confounded in Observational Social Network Studies”( available here).

Abstract: We consider processes on social networks that can potentially involve three phenomena: homophily, or the formation of social ties due to matching individual traits; social contagion, also known as social influence; and the causal effect of an individual's covariates on their behavior or other measurable responses. We show that, generically, all of these are confounded with each other. Distinguishing them from one another requires strong assumptions on the parametrization of the social process or on the adequacy of the covariates used (or both). In particular we demonstrate, with simple examples, that asymmetries in regression coefficients cannot identify causal effects, and that very simple models of imitation (a form of social contagion) can produce substantial correlations between an individual's enduring traits and their choices, even when there is no intrinsic affinity between them. We also suggest some possible constructive responses to these results.

The Moral Life of Babies

In Today's New York Times Magazine, Paul Bloom has a long interesting and easy-read piece (freely available here) on "The Moral Life of Babies" that concludes:

"Morality, then, is a synthesis of the biological and the cultural, of the unlearned, the discovered and the invented. Babies possess certain moral foundations - the capacity and willingness to judge the actions of others, some sense of justice, gut responses to altruism and nastiness. Regardless of how smart we are, if we didn't start with this basic apparatus, we would be nothing more than amoral agents, ruthlessly driven to pursue our self-interest. But our capacities as babies are sharply limited. It is the insights of rational individuals that make a truly universal and unselfish morality something that our species can aspire to."

Implied motion in Hokusai Manga

In NeuroReport, 21(4), pp 264-267, an interesting article by N. Osaka, D. Matsuyoshi, T. Ikeda, and M. Osaka of Kyoto and Osaka Universities, entitled "Implied motion because of instability in Hokusai Manga activates the human motion-sensitive extrastriate visual cortex: an fMRI study of the impact of visual art"

The authors write: "Visual artists developed various visual cues for representing implied motion in two-dimensional art. Photographic blur, action lines, affine shear, instability, superimposition, and stroboscopic images are possible technical solutions for representing implied movement. In a realistic painting, artists have tried to represent motion using superimposed or blurred images, while in abstract painting, like Marcel Duchamp artists have tried to portray a moving object on a static canvas by superimposing successive portrayals of the object in action...As one of a leading artist of the ‘Ukiyo-e' school in the 18th century, Hokusai made great progress in representing implied movement using unstable bodily action without introducing action lines or even blur." They go on to investigate how our visual brain creates the impression of motion using such implied movement clues.

The article is available (with subscription) here, and there is a good presentation here at the excellent blog Neurophilosophy.

Workshop: Language as an Evolutionary System

Poster-Conf-LECThese two days of talks and discussion will bring together scholars from a range of disciplines to discuss the value of applying evolutionary thinking to the cultural evolution of language as well as the commonalities and differences between various existing applications.

Linguistics has traditionally been cautious of analogies between evolution in language an in biology. Common ancestry and descent were proposed earlier for languages than for biological species, but while biological evolution has flourished into a science with solid theories that generate testable hypothesis, the study of the cultural evolution of language -- evolution that is independent of changes in the human genome -- is only beginning to test its innumerable, often speculative and unrigorous, theories. McMahon (1994) concluded that the way forward is Darwinian thinking. Since then, a number of independent proposals have convergently applied explicit analogies with the elements and processes of the evolutionary synthesis (Mayr & Provine, 1998) to cultural language dynamics. They all assume that language evolution and change are caused by cultural mechanisms such as social transmission and language usage in context.

Postdoctoral Research Position in Behavioral Economics

Central European University announces an opening for a postdoctoral fellow for two years, starting from September 2010 or later, to work on a project in behavioral economics regarding how people take into account their reputation --what others might think of them-- when making decisions. Specific research questions about the role of reputation in decision-making and the cognitive bases of reputation management include: do people use routines or heuristics whose function is to manage their reputation? Is there cross-cultural variations in the ways people manage their reputation and, if there is, why? What, of altruistic behavior, can be accounted for in terms of reputation management? To what extent, and in which sense, are people rational when they manage their reputation?

From cognitive science to an empirically-informed philosophy of logic

A workshop in Amsterdam (December 7-8 2010) entitled "From cognitive science and psychology to an empirically-informed philosophy of logic" will bring together logicians, philosophers, psychologists and cognitive scientists to discuss the interface between cognitive science and psychology, on the one hand, and the philosophy of logic on the other hand. More specifically, we wish to investigate the extent to which (if at all), and in what ways, experimental results from these fields may contribute to the formulation of an empirically-informed philosophy of logic, taking into account how human agents, logicians and non-logicians alike, in fact reason.

Up to five grants, each of the value of £1000, will be awarded to encourage anthropologists with good ethnographic knowledge of their field sites to perform an experimental study that will help provide comparative cross-cultural data on children's and adults' reasoning about human social kinds (deadline April 30, 2010).

Learn about Social Neuroscience

In the last issue of Neuron (65, 6), a "Special Feature: Reviews on Social Neuroscience," of unique interest to cognitive and social scientists, "a series of reviews [most of them freely available online] highlighting exciting research in the field of Social Neuroscience, which seeks to understand how the brain mediates social behaviors, and conversely, how social behaviors influence brain function. The reviews in this issue reflect the diverse and interdisciplinary nature of the field, ranging from the analysis of social interactions in "simple" model systems to the study of complex human behaviors."

From Chris and Uta Frith introductory "Overview":

"We have two suggestions as to what the special feature of human social cognition might be. One idea is that humans have an automatic (unconscious) drive to constantly update the difference between their own knowledge and the knowledge of specific others. Such a tendency is critical to the human drive to share novel information with others (Fitch et al., 2010). Such sharing, and indeed any useful communication, depends on knowing what other people don't know.

The other idea is that much human knowledge is represented in the explicit (conscious) form that is needed for sharing experiences. In other words, there is a special form of human communication where we are aware that we are sending and receiving signals (Sperber and Wilson, 1995). This means that, when we receive a signal we make a distinction (among other distinctions) between unintentional and deliberate signaling. We know that unintentional signals may have more veracity than deliberate signals because deliberate signals can be manipulated by the sender for the purposes of deception. On the other hand, we can use deliberate signals of communication to teach others. Both informal and formal teaching are the building materials of culture and serve to multiply learning from others (Gergely et al., 2007). This multiplication of experience over many generations may be the secret to the success of Homo sapiens."

LSE symposium on Personhood in a Neurobiological Age

An open and free Symposium on Personhood in a Neurobiological Age - Brain, Self and Society, at the LSE, 13 September 2010.

"It seems that we have learned more about the brain in the last decade than over the previous millennia of human history. But to what extent are developments in the 'new brain sciences' leading to a mutation in our understanding of selfhood? Are we in the midst of a move from ‘soul to brain', a radical restructuring of our understanding of human ‘psychology' and the rise of a ‘neuronal self'? If so, in what ways, and with what consequences, for individuals and for society, and for our ways of governing ourselves and others?"

Babies got rhythm!


A participant  listening to Mozart while her mother listens to speech. Watch the video here

Forthcoming in PNAS and freely available here, an article by Marcel Zentner and Tuomas Eerola: "Rhythmic engagement with music in infancy"

Abstract: Humans have a unique ability to coordinate their motor movements to an external auditory stimulus, as in music-induced foot tapping or dancing. This behavior currently engages the attention of scholars across a number of disciplines. However, very little is known about its earliest manifestations. The aim of the current research was to examine whether preverbal infants engage in rhythmic behavior to music. To this end, we carried out two experiments in which we tested 120 infants (aged 5-24 months). Infants were exposed to various excerpts of musical and rhythmic stimuli.... Infants' rhythmic movements were assessed by multiple methods involving manual coding from video excerpts and innovative 3D motion-capture technology. The results show that (i) infants engage in significantly more rhythmic movement to music and other rhythmically regular sounds than to speech; (ii) infants exhibit tempo flexibility to some extent ...; and (iii) the degree of rhythmic coordination with music is positively related to displays of positive affect. The findings are suggestive of a predisposition for rhythmic movement in response to music and other metrically regular sounds.

Do only humans share with non-kin?

"Comparisons between chimpanzees and humans have led to the hypothesis that only humans voluntarily share their own food with others. However, it is hard to draw conclusions because the food-sharing preferences of our more tolerant relative, the bonobo (Pan paniscus), have never been studied experimentally." write Brian Hare and Suzy Kwetuenda in their article "Bonobos voluntarily share their own food with others" (Current Biology, Vol. 20, Issue 5, R230-R231, 9 March 2010 - available here). They explain: "We gave unrelated bonobos the choice of either monopolizing food or actively sharing: we found that bonobos preferred to release a recipient from an adjacent room and feed together instead of eating all the food alone. Thus, food sharing in bonobos does not depend on kinship or harassment and suggests our own species' propensity for voluntary food sharing is not unique among the apes." And best of all, here is the video:

Is hearing God like being a skilled athlete?

Not often do we find in the American Anthropologist material of clear Cognition and Culture relevance. Here is a noteworthy exception: "The Absorption Hypothesis: Learning to Hear God in Evangelical Christianity" (vol. 112,March 2010 issue, available here) by Tanya. M. Luhrmann (whose LSE-ICCI lecture on the same topic is now online), Howard Nusbaum, and Ronald Thisted. They say that their approach "builds on but differs from the approach to religion within the culture-and-cognition school."

The article begins: "How does God become real to people when God is understood to be invisible and immaterial, as God is within the Christian tradition? This is not the question of whether God is real but, rather, how people learn to make the judgment that God is present. ... it may be the case that hearing God speak and having other vivid, unusual spiritual experiences that seem like unambiguous evidence of divine presence might be, in some respects, like becoming a skilled athlete. In this article, we argue that something like talent and training are involved in the emergence of certain kinds of religious experiences."

The conclusion: "Religion and spirituality are enormously complex human phenomena. Here we suggest that we may be able to identify one kind of skill that can be cultivated, for which some may have more of a proclivity or talent than others. Absorption does not explain religion and far less does it explain it away. But to understand that some people may have developed their talent more than others may help us to understand why some people become gifted practitioners of their faith and others with the intention and desire to do so struggle and do not. And it reminds us, as Maurice Bloch (2008) remarks, that at the heart of the religious impulse lies the capacity to imagine a world beyond the one we have before us."

Workshop: Culture and Cognition in Asia

March 11th – 12th, 2010, National University of Singapore, Asia Research Institute.

Research in both the social and cognitive sciences has increasingly focused on the complex dynamic between cultural meaning and practices with cognitive processes. From the sociology of science to the anthropology of religion, cultural studies have taken a cognitive turn to explore a wide range of topics including distributed cognition in technological systems, memory and religious rituals, and the neuroeconomics of decisions about risk. Cognitive neuroscientists have likewise begun to more closely examine how culture influences cognition in areas such as perception and attention, healing and placebo effects, language processing and speech disorders, and even the psychosomatics of meditation. Emerging out of this multidisciplinary interest in culture and cognition is a new understanding of the plasticity of embodiment that emphasizes change in how cultural practices, human cognition and behavior, and even the natural environment influence each other. Cultural change and neurocognitive plasticity are the result of active human agency rather than purely passive inscription by social, technological, or biological systems.

New: Our Cognition and Culture Reader and our Bookstore

We are today putting online the beta version of a Cognition and Culture Reader with links to relevant papers, books and blog posts. All the papers are freely available on the Internet. All the books listed (and other books mentioned in our blog or news) can be purchased at our new online Bookstore (and we get a modest percentage on the sale of these and any other Amazon book purchased through our bookstore, which we hope will help us cover our costs).

The reader has been prepared by Nicolas Baumard. Of course, it should be more comprehensive and it will need regular updating. We would be grateful to members of the Institute for comments and suggestions (keeping in mind that we are aiming at a useful short selection, not at exhaustivity). Still, as it is, we hope you will find it of use.

How many minutes does it take for social norms to inhibit survival instinct?

Forthcoming in PNAS, an innovative study entitled "Interaction of natural survival instincts and internalized social norms exploring the Titanic and Lusitania disasters" by Bruno S. Frey, David A. Savage and Benno Torgler (and already available here alas with subscription; earlier version freely available here)

Abstract: "...This study explores the interaction of natural survival instincts and internalized social norms using data on the sinking of the Titanic and the Lusitania. We show that time pressure appears to be crucial when explaining behavior under extreme conditions of life and death. Even though the two vessels and the composition of their passengers were quite similar, the behavior of the individuals on board was dramatically different. On the Lusitania, selfish behavior dominated (which corresponds to the classical homo economicus); on the Titanic, social norms and social status (class) dominated, which contradicts standard economics. This difference could be attributed to the fact that the Lusitania sank in 18 min, creating a situation in which the short-run flight impulse dominated behavior. On the slowly sinking Titanic (2 h, 40 min), there was time for socially determined behavioral patterns to reemerge. Maritime disasters are traditionally not analyzed in a comparative manner with advanced statistical (econometric) techniques using individual data of the passengers and crew. Knowing human behavior under extreme conditions provides insight into how widely human behavior can vary, depending on differing external conditions."
