A Materialist's Credo

This post passes on a recent effort to put down some basic ideas in as few words as I can manage.

A Materialist’s Credo

In the beginning was the cosmos, fundamentally as incomprehensible to our human brains as quantum chemistry is to a dog’s brain.

What our human brains can understand is that our ultimate emergence from countless generations of less complex organisms can be largely explained by a  simple mechanism that tests the reproductive fitness of varying replicants.

Systems that try to predict the future and dictate whether to go for it or scram - from the chemotaxis of bacteria to the predictive processing of our humans brains - have proved to be more likely to survive and propagate.

Modern neuroscience has proved that our experienced perceptions of sensing and acting are these predictions.  They are fantasies, or illusions, as is our sense of having a self with agency that experiences value, purpose, and meaning. Everything we do and experience is in the service of reducing surprises by fulling these fantasies. An array of neuroendocrine mechanisms have evolved to support this process because it forms the bedrock of human culture and language.

We are as gods, who invent ourselves and our cultures through impersonal emergent processes rising from our biological substrate.

Personal and social dysfunctions can sometimes be addressed by insight into this process, as when interoceptive awareness of the settings of  our autonomic nervous system's axes of arousal, valence, and agency allows us to dial them to more life sustaining values and better regulate our well-being in each instance of the present.

We can distinguish this autonomic substrate from the linguistic cultural overlay it it generates, and allow  the latter to be viewed in a more objective light. This is a deconstruction that permits us to not only let awareness rest closer to the 'engine room' or 'original mind' underlying its transient reactive products, but also to derive from this open awareness the kind of succor or equanimity we once found in the imagined stability of an external world.

Hopefully the deconstruction that takes us into this metaphorical engine room makes us more able to discern and employ illusions that enhance continuation rather than termination of our personal and social evolutionary narratives.

Architectural experience influences the processing of others’ body expressions

An open source article by Presti et al:  

Significance

The motor system has been recognized as a fundamental neural machinery for spatial and social cognition, making the study of the interplay between architecture and social behavior worthwhile. Here, we tested how a virtual architectural experience alters the subsequent processing of body expressions, showing that the motor system participates at two distinct stages: the earliest influenced by the dynamic architectural experience and the latter modulated by the actual physical characteristics. These findings highlight the existence of an overlapping motor neural substrate devoted to spatial and social cognition, with the architectural space exerting an early and possibly adapting effect on the later social experience. Ultimately, spatial design may impact the processing of human emotions.

Abstract

The interplay between space and cognition is a crucial issue in Neuroscience leading to the development of multiple research fields. However, the relationship between architectural space and the movement of the inhabitants and their interactions has been too often neglected, failing to provide a unifying view of architecture's capacity to modulate social cognition broadly. We bridge this gap by requesting participants to judge avatars’ emotional expression (high vs. low arousal) at the end of their promenade inside high- or low-arousing architectures. Stimuli were presented in virtual reality to ensure a dynamic, naturalistic experience. High-density electroencephalography (EEG) was recorded to assess the neural responses to the avatar’s presentation. Observing highly aroused avatars increased Late Positive Potentials (LPP), in line with previous evidence. Strikingly, 250 ms before the occurrence of the LPP, P200 amplitude increased due to the experience of low-arousing architectures, reflecting an early greater attention during the processing of body expressions. In addition, participants stared longer at the avatar’s head and judged the observed posture as more arousing. Source localization highlighted a contribution of the dorsal premotor cortex to both P200 and LPP. In conclusion, the immersive and dynamic architectural experience modulates human social cognition. In addition, the motor system plays a role in processing architecture and body expressions suggesting that the space and social cognition interplay is rooted in overlapping neural substrates. This study demonstrates that the manipulation of mere architectural space is sufficient to influence human social cognition.

Does a "P-factor" underlie core attributes of mental health maladies?

I want to point to an open source "Core Concepts" article in PNAS by David Adam that presents "the views of some psychiatrists who argue that the same bit of biology—genetics gone awry or some misplaced brain circuitry—could underlie the vast majority of humanity’s mental health problems. Studies have shown, for example, that many of the same genes seem to drive increased risk for autism, attention-deficit hyperactivity disorder (ADHD), bipolar disorder, major depression, and schizophrenia. They call this as-yet-unidentified common cause the “psychopathology factor,” or “p-factor” for short."
