Talk on the social brain hypothesis in fish

Tomorrow there will be a workshop at the Merida site of the Institute for Applied Mathematics and Systems Research. The topic is “La Computación y las Matemáticas Aplicadas para Resolver Problemas en la Ciencia”.

I was invited to give a talk and will present “The social brain hypothesis in fish: A big data approach”.

Here is the program of the event:

Is there room for normativity in a dynamical world?

Tomorrow at 2pm I will be giving an online talk for the ENactive Seminars Online (ENSO) Series. Here are the title and abstract:

Is there room for normativity in a dynamical world?

Enactivism rejects the standard working hypothesis of cognitive science, according to which all cognition involves the unconscious manipulation of mental representations, and replaces it with a dynamical systems account. And yet enactivism resists other, purely dynamical approaches that see no role for any kind of subjectivity, because it appeals to the role of our lived phenomenology and claims that living beings behave with respect to norms directed at maintaining their viability.

So far, this middle way seems to be philosophically unsatisfactory: at best it allows us to claim that acting in accordance with experience or norms just is a certain kind of dynamic pattern. But this turns subjectivity into a mysterious difference that makes no difference as such with respect to the unfolding of those patterns, which is completely determined by the dynamics alone.

This calls for deeper philosophical reflection about how it is possible for subjectivity to play a role in an objective world while avoiding a regression to the untenable positions of either representationalism or eliminativism.

Collective origins of the genetic code

Later today I am giving the weekly colloquium at the Center for Complexity Sciences (C3) at our main campus of UNAM. The topic will be our ongoing work on a simulation model of the collective origins of the genetic code. Details of the colloquium below:

4th International Colloquium of the Cognitive Sciences

Tomorrow starts the 4th International Colloquium of the Cognitive Sciences, which will be held Oct. 4-6 at the Centro Lombardo Toledano in Mexico City.

Several members of the 4E Cognition Group will participate in the colloquium and present their research. I was invited to give a talk and the title is “On the role of normativity in cognitive science”.

International Colloquium of Philosophy and Psychiatry

I have been invited as a plenary speaker to the International Colloquium of Philosophy and Psychiatry, which will take place August 31 – September 2 in Bogota, Colombia. The title and abstract of my talk are as follows:

Integrating phenomenology and systems theory: The case of embodied memory

I will give an introduction to dynamical systems analysis and use it to formalize and ground the phenomenology 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 computational thought experiments 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 psychopathology that takes into account the cognitive effects of undergoing changes in one’s body and in one’s relationship to the spatial and social environment.

Seminar on the origins of the genetic code

Next week Jorge and I will give a seminar to report on the work we did during our 2-month stay at the Earth-Life Science Institute:

An iterated learning model of the origin of the genetic code

Tom Froese (National Autonomous University of Mexico, UNAM)
Jorge Campos (National Autonomous University of Mexico, UNAM)

Date: July 25, 2017
Time: 14:00
Room: ELSI-2 Building – ELSI Lounge
Host: Nathaniel Virgo

Theories of the origin of the genetic code take translation for granted and assign an essential role to natural selection and/or mutation of hereditable traits to explain its non-randomness and error robustness. And yet the translation system depends on high fidelity replication. Woese proposed a solution to this fundamental bootstrapping problem by arguing that optimization of the code could have preceded and facilitated evolution of the translation system, and that its evolution was accelerated by communal innovation. He conjectured that early evolution was dominated by horizontal exchange of cellular components among loosely organized protocells rather than by vertical transmission of genetic material, and that lineages of individuals did not exist until after the emergence of the last universal common ancestor. Crucial outstanding problems are clarifying the agency of selection in communal evolution, and verifying whether it provides a rational basis for codon assignments. Here we demonstrate that horizontal transfer of code fragments can in principle give rise to key properties of the genetic code. In accordance with Woese’s claim that the dynamic of communal evolution is primarily determined by the organization of the recipient cell, and taking inspiration from comparisons between the advent of the genetic code and the emergence of human language, we created an iterated learning model of a group of protocells. Previous models of the origin of the genetic code have reproduced its regularity and optimality as well as its universality, but this is the first model to reproduce these features without vertical descent. This proof of concept suggests another modality of evolution: not only was Darwinian evolution (dominated by vertical transmission of genes) arguably preceded by Lamarckian evolution (vertical transmission with heredity of acquired traits), the latter was possibly preceded by Woesian evolution (dominated by horizontal acquisition).

Workshop on distributed cognition

Today and on Wednesday there will be a Workshop on Distributed Cognition taking place at the Earth-Life Science Institute (ELSI) in Tokyo. The workshop is organized by the ELSI Origins Network.

I was invited to give a talk and my contribution will be on “distributed memory”, based on the talk I recently gave at the conference on Formation of Embodied Memory in Heidelberg.

Symposium on Hallucinations and Perceptual Experience

I’ve been invited to give a talk at a Symposium on Hallucinations and Perceptual Experience, which Prof. Juan Gonzalez has organized in the context of the Second International Conference of Transdisciplinary Research in the Social Sciences and Humanities.

The event will start tomorrow at 10:00 in Cuernavaca, Mexico.

The line-up is as follows:

Prof. Juan Gonzalez (speaker)
Prof. Jose Luis Diaz (speaker)
Dr. Tom Froese (speaker)
Dr. Glenda Satne (discussant)

The title of my contribution is: “Hallucinations: internal fictions, external realities, or something in-between?” (Alucinaciones: ¿ficciones internas, realidades externas o algo intermedio?).
