Seminar on the origins of the symbolic mind

I was invited to give a talk at UNAM’s Instituto de Investigaciones Filosoficas this Wednesday as part of the Rationality, Reasoning, and Cognition seminar series. The title of my contribution is “How did humans overcome the cognitive gap? On the origins of the symbolic mind”. Details in the flyer below:


Talk: Dynamics of Embodied Memory: Temporality, Spatiality, and Sociality

The Marsilius-Kolleg is organizing a conference series on the topic of comprehensive anthropology.

Next month the series will start with an International Conference on the Formation of Embodied Memory, which will take place at the University of Heidelberg, April 6-8. I was invited to give a talk:

Dynamics of Embodied Memory: Temporality, Spatiality, and Sociality

Tom Froese

This talk presents a dynamical systems analysis of the temporal processes that contribute to the constitution of embodied memory. Three kinds of extra-neural processes will be considered: 1) physiological dynamics, 2) movement dynamics, and 2) social interaction dynamics. Their potential to serve as forms of memory will be illustrated on the basis of three simple agent-based models. These examples help to demonstrate the problems faced by a purely brain-based account of the self and its capacities. They also support the adoption of a broader notion of forgetting, which takes into account the cognitive effects of undergoing changes in one’s relationship to the spatial and social environment, for example displacement from one’s home and separation from one’s acquaintances.

Course on the enactive approach and its contributions to psychotherapy

This Friday and Saturday I will give a two-day course entitled “La aproximación enactiva y sus aportes para la psicoterapia” at the Centro de Psicoterapia de Premisas in San Luis Potosí, Mexico.

Living systems: chaotic, stochastic, and/or indeterministic?

I was invited to lead the discussion in a session of the Seminar of Science and Society at the Centre for the Sciences of Complexity. I will focus on the relationship between autonomy and uncertainty. Details can be found in the flyer below:

International Symposium on the Sociopolitical Organization of Teotihuacan

It has been 5 years since I moved to Mexico to create a computational model of the sociopolitical organization of ancient Teotihuacan. I am happy to report that this project has matured. I am involved in the organization of the International Symposium on the Sociopolitical Organization of Teotihuacan, which will bring together the world’s leading experts working on this topic.


At the symposium I will I gave talk on the latest results of the model. The title and abstract are as follows:

A computational model of Teotihuacan’s collective government: New insights into role of the city’s division into districts

Tom Froese

Experts remain divided about the nature of the sociopolitical system of ancient Teotihuacan, which was one of the earliest and largest urban civilizations of the Americas. Excavations hoping to find compelling evidence of powerful rulers, such as a royal tomb, keep coming away empty-handed. But the alternative possibility of a corporate or collective government still remains poorly understood. There is a lack of evidence of a powerful bureaucracy, such as durable record keeping, but a decentralized network limited to the level of neighborhood representatives seems susceptible to problems of collective action.

Previously we used a computational model to show that in principle this latter worry is unfounded, as long as we assume that the network’s topology could be transformed via community rituals and was not strongly subdivided. Here we extend this model to investigate whether increased social hierarchy could mitigate the negative effects of strong divisions. We found a special synergy between hierarchy and community ritual in that only their combination improved the extent of cooperation, which is consistent with portrayals of the elite as religious specialists serving the public good and with the apparent absence of extensive secular institutions.

Current work is investigating whether a reduction in the city’s number of districts could reduce the necessity for this kind of centralized hierarchy.

Philosophy events at UOW

Today we will have a workshop on “The Origins and Nature of Contentful Minds: Continuity, Transformation, Integration?” in the University of Wollongong’s Research Hub, Building 19 – Room 2072. The program can be downloaded here.

My contribution is entitled: “Does the evolved apprentice model remain in the zone of latent solutions?”

Then from Wednesday to Friday there will be the 2016 UOW Philosophy Training Conference, where I will give an invited talk with the title “Hallucinations: Inner fictions, outer realities, or something in between?”

Understanding complexity

posterThe prestigious Colegio Nacional of Mexico is holding a two-day event on complexity and interdisciplinarity “Entendiendo la complejidad: La multidisciplina en las ciencias“, September 27-28.

The event is open to the public and will be broadcast live.

I was invited to give a talk about my research as a member of the Centro de Ciencias de la Complejidad.

The title of my talk is “La organización política de Teotihuacan como sistema complejo”, and is scheduled to start tomorrow at 18:15.

The full program can be found here.

Talk on History and Philosophy of Origins Research

I have been invited to give a talk at the EON Workshop on History and Philosophy of Origins Research, which will be held August 24-26 at the Earth-Life Science Institute in Tokyo.

The title and abstract of my contribution are as follows:

The concept of the individual in cognitive science and origins of life

Tom Froese

The field of cognitive science was inaugurated on the basis of the computational theory of mind. The metaphor of the digital computer had several implications: it restricted the field to understanding all of cognition in terms of the manipulation of symbols; it focused research on passive information processing; and it limited the scope of inquiry to processes taking place within the physical boundaries of the system. This concept of an individual, as a system engaged in passive internal symbol manipulation, seems to be implicitly shared by theories of the origins of life that are focused on encapsulated processing of informational molecules. Yet in cognitive science this concept of the individual has been undergoing a series of deep revisions, such that it is now replaced by its exact opposite: an individual is seen as primarily a system that is embodied, extended, and as actively engaged in direct relations with the physical and social environment. I analyze what origins of life research could learn from this shift in the history of cognitive science.

Game theoretic model of Maya warfare and the royal court

In collaboration with Roberto Ulloa we modeled the effects of Maya warfare on elite social network topology. The paper will be presented at this year’s ALIFE 2016 conference and will be published in its proceedings by MIT Press.

Nobility-targeting raids among the Classic Maya: Cooperation in scale-free networks persists under tournament attack when population size fluctuates

Roberto Ulloa and Tom Froese

Cooperation in scale-free networks has proven to be very robust against removal of randomly selected nodes (error) but highly sensitive to removal of the most connected nodes (attack). In this paper we analyze two comparable types of node removal in which the removal selection is based on tournaments where the fittest (raids) or the least fit (battles) nodes are chosen. We associate the two removals to two types of Maya warfare offences during the Classic period. During this period of at least 500 years, political leaders were able to sustain social order in spite of attack-like offences to their social networks. We present a computational model with a population fluctuation mechanism that operates under an evolutionary game theoretic approach using the Prisoner’s Dilemma as a metaphor of cooperation. We find that paradoxically battles are able to uphold cooperation under moderate levels of raids, although raids do have a strong impact on the network structure. We infer that cooperation does not depend as much on the structure as it does on the underlying mechanism that allows the network to readjust. We relate the results to the Maya Classic period, concluding that Mayan warfare by itself cannot entirely explain the Maya political collapse without appealing to other factors that increased the pressures against cooperation.


First International Conference on Language and Enaction

I have been invited as a keynote speaker to the First International Conference on Language and Enaction, which will take place June 1-3 in Clermont-Ferrand, France.

The title and abstract of my talk are as follows:

From lower to higher, from self to other: Approaching the phenomenon of language from the bottom up

Tom Froese

The enactive approach to cognitive science is currently faced by the challenge of overcoming the cognitive gap between its theories of the basic organismic mind and specifically human capacities centered on symbolic cognition. At the same time there appears to be a tension between its self-related concepts, such as autopoiesis and adaptivity, and its other-related concepts, such as participatory sense-making and languaging. I argue that these tensions can be resolved in a complementary fashion by clarifying that enactive theory does not adhere to an internalist epistemology, which can be most clearly seen in terms of its rejection of methodological individualism. Once our thinking is freed from that isolating framework it becomes evident that the enactive approach has the potential to become a fruitful paradigm for linguistics. I finish by considering its implications for language evolution, in particular regarding claims of innateness based on the assumption of the poverty of the stimulus as well as gesture-first theories.

To kick off this trip to Europe I will also give two seminars:

On May 30 I will talk about “Ritualized mind alteration and the origins of the symbolic mind: Recent insights from cognitive science” at the Collegium Helveticum in Zurich.

And on May 31 I will give a talk with the title “Can we extend the sensorimotor approach to social perception?” at Kevin O’Regan’s FEEL project lab in Paris.
