Human society is currently undergoing a socio-cultural ETI
An evolutionary transition in individuality (ETI) occurs when a previously independent organism becomes a lower level unit within a higher hierarchical level (for example, cells in an organism, ants in a colony). Based on archaeological and historical accounts from the last 12000 years, this article “Human societal development: is it an evolutionary transition in individuality?”…

EXplore-versus-EXploit problems
Trade-offs between producing costly movements for gathering information (‘explore’) and using previously acquired information to achieve a goal (‘exploit’) arise in a wide variety of problems, including foraging, reinforcement learning and sensorimotor control. Determining the optimal balance between exploration and exploitation is computationally intractable, necessitating heuristic solutions. In “Mode switching in organisms for solving explore-versus-exploit…

Conceptual Bootstrapping (human cognition)
To tackle a hard problem, it is often wise to reuse and recombine existing knowledge. Such an ability to bootstrap enables us to grow rich mental concepts despite limited cognitive resources. This article presents a computational model of conceptual bootstrapping. This model uses a dynamic conceptual repertoire that can cache and later reuse elements of…

How adults understand what young children say
When babies first begin to talk, their vocabulary is very limited. Often one of the first sounds they generate is “da,” which may refer to dad, a dog, a dot, or nothing at all. How does an adult listener make sense of this limited verbal repertoire? A new study “How adults understand what young children…

Puzzled …? – Consider the Bayesian brain hypothesis!
Dysfunctional breathing disorder(s) (DBD) is an umbrella term for a set of poorly distinguishable clinical conditions including the most emblematic and anciently known hyperventilation syndrome. DBD affects in a variable proportion (between 5 and 35%) both adults and children, with a highly negative impact on health-related quality of life. DBD is consensually considered as a…

Bayesian models of perception and action (free e-book)
Bayesian models of perception and action An introduction By Wei Ji Ma, Konrad Kording, and Daniel Goldreich An accessible introduction to constructing and interpreting Bayesian models of perceptual decision-making and action. Many forms of perception and action can be mathematically modeled as probabilistic — or Bayesian — inference, a method used to draw conclusions from…

The computational power of the human brain
Peter J. Gebicke-Haerter published a great review article with this title. I selected some snippets and the key conclusion: At the end of the 20th century, analog systems in computer science have been widely replaced by digital systems due to their higher computing power. Nevertheless, the question keeps being intriguing until now: is the brain…

A top-down, bottom-up model of circuit function for anxiety and depression.
A great review article describes the bottom-up and top-down processing from Marr’s computational-algorithmic-implementation perspective to understand depressive and anxious disease states. The review illustrate examples of bottom-up processing as basolateral amygdala signaling and projections and top-down processing as medial prefrontal cortex internal signaling and projections. Understanding these internal processing dynamics can help us better model…

“Fitness” Beats “Truth”
The “Fitness-Beats-Truth Theorem” provides a quantitative measure of the extent to which the fitness-only strategy dominates the truth strategy, and of how this dominance increases with the size of the perceptual space. The FBT Theorem supports the Interface Theory of Perception. The Interface Theory of Perception is discussed and described in detail in 2015 by…

The Physics of Survival
Please enjoy the fascinating discussion of the free energy principle with Dr. Maxwell Ramstead, a leading thinker exploring the intersection of math, physics, and philosophy and Director of Research at VERSES. The 2 hour discussion includes great details on FEP. The FEP was proposed by renowned neuroscientist Karl Friston, this principle offers a unifying theory…

Complexity, Entropy & the Physics of Information
The specter of information is haunting sciences. With these words, Wojciech H. Zurek invited fellow scientists to attend the 1989 Santa Fe Institute workshop on which this proceedings volume is based. Thermodynamics, statistical mechanics, the quantum theory of measurement, the physics of computation, dynamical systems, molecular biology, and computer science — information remains central to the…

The IDEA (Internal Dominance over External Attention )
Sam Verschooren and Tobias Egner published “ When the mind’s eye prevails: “The Internal Dominance over ExternalAttention (IDEA) hypothesis“. The IDEA hypothesis asserts, contrary to the traditional view of attention as being primarily externally oriented, that attention is inherently biased toward internal information. Mine inner sense predominates in such a way over my five senses…

The self is an illusion
The truth is that your left brain has been interpreting reality for you your whole life, and if you are like most people, you have never understood the full implications of this. This is because we mistake the story of who we think we are for who we truly are. “Why are you unhappy?Because 99.9 percent of…

Decoding reward–curiosity conflict in decision-making from irrational behaviors
Humans and animals are not always rational. “Decoding reward–curiosity conflict in decision-making from irrational behaviors” discusses the fact humans not only rationally exploit rewards but also explore an environment owing to their curiosity. However, the mechanism of such curiosity-driven irrational behavior is largely unknown. The article develops a decision-making model for a two choice task…
