Wild systems theory (WST) – context and relationships make reality meaningful

Edward has posted some great thoughts and resources on embodied cognition (EC). I stumbled on some interesting information on a line of thinking within the EC literature. I find contextualist, connectivist approaches compelling in their ability to address complex-systems such as life and (possibly) consciousness. Wild systems theory (WST) “conceptualizes organisms as multi-scale self-sustaining embodiments of the phylogenetic, cultural, social, and developmental contexts in which they emerged and in which they sustain themselves. Such self-sustaining embodiments of context are naturally and necessarily about the multi-scale contexts they embody. As a result, meaning (i.e., content) is constitutive of what they are. This approach to content overcomes the computationalist need for representation while simultaneously satisfying the ecological penchant for multi-scale contingent interactions.”While I find WST fascinating, I’m unclear on whether it has been or can be assessed empirically. What do you think? Is WST shackled to philosophy?

Can one person know another’s mental state? Physicalists focus on how each of us develops a theory of mind (TOM) about each of the other people we observe. TOM is a theory because it is based on assumptions we make about others’ mental states by observing their behaviors. It is not based on any direct reading or measurement of internal processes. In its extreme, the physicalist view asserts that subjective experience and consciousness itself are merely emergent epiphenomena and not fundamentally real.

EC theorists often describe emergent or epiphenomenal subjective properties such as emotions and conscious experiences as “in terms of complex, multi-scale, causal dynamics among objective phenomena such as neurons, brains, bodies, and worlds.” Emotions, experiences, and meanings are seen to emerge from, be caused by or identical with, or be informational aspects of objective phenomena. Further, many EC proponents regards subjective properties as “logically unnecessary to the scientific description.” Some EC theorists conceive of the non-epiphenomenal reality of experience in a complex systems framework and define experience in terms of relational properties. In Gibson’s (1966) concept of affordances, organisms perceive behavioral possibilities in other organisms and in their environment. An affordance is a perceived relationship (often in terms of utility), such a how an organism might use something–say a potential mate, prey/food, or a tool. Meaning arises from “bi-directional aboutness” between an organism and what it perceives or interacts with. Meaning is about relationship.

(A very good, easy read on meaning arising from relationships is the book Learning How to Learn, by Novak and Gowin. In short, it’s the connecting/relating words such as is, contains, produces, consumes, etc., that enable meaningful concepts to be created in minds via language that clarifies context.)

Affordances and relationality at one level of organization and analysis carve out a non-epiphenomenal beachhead but do not banish epiphenomena from that or other levels. There’s a consideration of intrinsic, non-relational properties (perhaps mass) versus relational properties (such as weight). But again, level/scale of analysis matters (“mass emerges from a particle’s interaction with the Higgs field” and is thus relational after all) and some take this line of thinking to a logical end where there is no fundamental reality.

In WST, “all properties are constituted of and by their relations with context. As a result, all properties are inherently meaningful because they are naturally and necessarily about the contexts within which they persist. From this perspective, meaning is ubiquitous. In short, reality is inherently meaningful.”

Neuroscience of Empathy

(This is copied from the Meetup site. Thanks again to Brent for hosting.)

Details

Empathy is the ability to put yourself in another person’s shoes and understand how they feel- to be them, even for a second. It’s the link between self and others: how we connect, heal, and relate. Considering its importance in every aspect of our lives, we are taking a deeper look at the neuroscience behind empathy.

    From the link: “Patterns associated with empathic care, for instance, overlapped with systems in the brain associated with value and reward, such as the ventromedial prefrontal cortex and the medial orbitofrontal cortex. In contrast, patterns of empathic distress overlapped with systems in the brain known for mirroring, such as the premotor cortex and the primary and secondary somatosensory cortices, which help an individual simulate or imagine what another person is feeling or thinking.”

    From the conclusion: “Shared representations of affective states are activated from the top down in more  cognitive forms of empathy, which recruit additional executive and visuospatial processes. However, the literature overestimates distinctions between emotional and cognitive empathy, following traditional practices to dichotomize in science and philosophy. Despite each
    having unique features, affective and cognitive empathy both require access to the shared representations of emotion that provide simulations with content and an
    embodied meaning.”

    And this article. Abstract: “Recent research on empathy in humans and other mammals seeks to dissociate emotional and cognitive empathy. These forms, however, remain interconnected in evolution, across species and at the level of neural mechanisms. New data have facilitated the development of empathy models such as the perception–action model (PAM) and mirror-neuron theories. According to the PAM, the emotional states of others are understood through personal, embodied representations that allow empathy and accuracy to increase based on the observer’s past experiences. In this Review, we discuss the latest evidence from studies carried out across a wide range of species, including studies on yawn contagion, consolation, aid-giving and contagious physiological affect, and we summarize neuroscientific data on representations related to another’s state.” https://www.nature.com/nrn/journal/v18/n8/full/nrn.2017.72.html

    Jimmy Kimmel in this video highlights a lot of what we talked about tonight. Yes, we need to feel empathy for those killed an injured in the Las Vegas shooting, but we also need to DO something about it. Meaning gun legislation. He highlights those in Congress who are making it easier instead of harder to obtain the kind of automatic weapons used in this mass murder. The reality is we must make such guns illegal, for it acts on our empathy and morality in a way that protects and serves us. https://www.youtube.com/watch?v=ruYeBXudsds

Downward mental causation and free will

I know, to free will or not to free will, that is the hackneyed question debated in philosophical circles since we learned how to talk. But here’s a cognitive neuroscientist’s research on “how neuronal code underlies top-down mental causation.” It’s a long video, over 2 hours, and I have yet to complete it. Here is Peter Tse’s CV.  Here is his book on the topic is. Here is a good summary of Tse’s work on the topic.

Future discussion topic recommendations

Several of us met on Labor Day with the goal of identifying topics for at least five future monthly meetings. (Thanks, Dave N, for hosting!) Being the overachievers we are, we pushed beyond the goal. Following are the resulting topics, which will each have its own article on this site where we can begin organizing references for the discussion:

  • sex-related influences on emotional memory
    • gross and subtle brain differences (e.g., “walls of the third ventricle – sexual nuclei”)
    • “Are there gender-based brain differences that influence differences in perceptions and experience?”
    • epigenetic factors (may need an overview of epigenetics)
  • embodied cognition
    • computational grounded cognition (possibly the overview and lead-in topic)
    • neuro-reductionist theory vs. enacted theory of mind
    • “Could embodied cognition influence brain differences?” (Whoever suggested this, please clarify.)
  • brain-gut connection (relates to embodied cognition, but can stand on its own as a topic)
  • behavioral priming and subliminal stimuli (effects on later behavior)
  • incremental theory – “The Dark Side of Malleability”
  • creative flow as a unique cognitive process
  • Eastern philosophies and psychology – a psychology of self-cultivation
  • neuroscience of empathy – effects on the brain, including on neuroplasticity (discussed October 2017)
  • comparative effects of various meditative practices on the brain
  • comparative effects of various psychedelics on the brain
  • effects of childhood poverty on the brain
  • neurocognitive bases of racism

If I missed anything, please edit the list (I used HTML in the ‘Text’ view to get sub-bullets). If you’re worried about the formatting, you can email your edits to cogniphile@albuquirky.net and Mark will post your changes.

Brain’s facial-recognition mechanism revealed

Caltech researchers have identified the brain mechanisms that enable primates to quickly identify specific faces. In a feat of efficiency, surprisingly few feature-recognition neurons are involved in a process that may be able to distinguish among billions of faces. Each neuron in the facial-recognition system specializes in noticing one feature, such as the width of the part in the observed person’s hair. If the person is bald or has no part, the part-width-recognizing neuron remains silent. A small number of such specialized-recognizer neurons feed their inputs to other layers (patches) that integrate a higher-level pattern (e.g., hair pattern), and these integrate at yet higher levels until there is a total face pattern. This process occurs nearly instantaneously and works regardless of the view angle (as long as some facial features are visible). Also, by cataloging which neurons perform which functions and then mapping these to a relatively small set of composite faces, researchers were able to tell which face a macaque (monkey) was looking at.

These findings seem to correlate closely with Ray Kurzweil’s (Google’s Chief Technology Officer) pattern-recognition theory of mind.

Mathematical field of topology reveals importance of ‘holes in brain’

New Scientist article: Applying the mathematical field of topology to brain science suggests gaps in densely connected brain regions serve essential cognitive functions. Newly discovered densely connected neural groups are characterized by a gap in the center, with one edge of the ring (cycle) being very thin. It’s speculated that this architecture evolved to enable the brain to better time and sequence the integration of information from different functional areas into a coherent pattern.

Aspects of the findings appear to support Edelman’s and Tononi’s (2000, p. 83) theory of neuronal group selection (TNGS, aka neural Darwinism).

Neuroplasticity at the neuron and synapse level – Neurons sort into functional networks

“Until recently, scientists had thought that most synapses of a similar type and in a similar location in the brain behaved in a similar fashion with respect to how experience induces plasticity,” Friedlander said. “In our work, however, we found dramatic differences in the plasticity response, even between neighboring synapses in response to identical activity experiences.”

“Individual neurons whose synapses are most likely to strengthen in response to a certain experience are more likely to connect to certain partner neurons, while those whose synapses weaken in response to a similar experience are more likely to connect to other partner neurons,” Friedlander said. “The neurons whose synapses do not change at all in response to that same experience are more likely to connect to yet other partner neurons, forming a more stable but non-plastic network.”
