Living in the future’s past

I watched a good documentary last night titled, Living in the Future’s Past, a project organized, produced, and narrated by Jeff Bridges. It’s available through your Albuquerque Public Library account’s access to Hoopla Digital, Amazon Prime video, and other services. It lays out the modern dilemma of having a pre-neolithic brain in a Neolithic era and posits several questions that align closely with the theme of our current discussion . The film has commentary from diverse scientific experts, including Daniel Goldman (emotional and social intelligence and mindfulness). The upshot is a recurring suggestion our current brain functionality is capable of reframing our perspective and modulating our perceptions and behaviors around carefully constructed focal questions that get at what sort of future(s) we desire. I like this approach—so well in fact that I Had reserved some web domains months ago: WorldIChoose.org, WorldIChoose.com, ChooseMyWorld.org, and ChooseMyWorld.com. These domains are not active yet. They will relate to the novel I’m writing and to a related non-fiction project. Edward is onto an important approach in looking to semantics (framing, etc.).

Also, on a short-term level, cultural evolution (including language and semantics) appears much more potent a driver than physiological evolution. Given that, I recently purchased a book by an author who goes into great depth on cultural evolution. The book is Cognitive Gadgets: The Cultural Evolution of Thinking, by Cecelia Heyes. I may put it forward for a future discussion.

Humans are still evolving

From this article. See it for details.

“Evolution is an ongoing process, although many don’t realize people are still evolving. It’s true that Homo sapiens look very different than Australopithecus afarensis, an early hominin that lived around 2.9 million years ago. But it is also true that we are very different compared to members of our same species, Homo sapiens, who lived 10,000 years ago — and we will very likely be different from the humans of the future.

“What we eat, how we use our bodies, and who we choose to have kids with are just some of the many factors that can cause the human body to change. Genetic mutations lead to new traits — and with the world population now above 7 billion and rising, the chances of genetic mutations that natural selection can potentially act on is only increasing. Don’t believe us? Inverse presents three examples of recent changes to the human body.”

Consciousness in Humanoid Robots

New ebook from Frontiers in Science. The blurb:

Building a conscious robot is a grand scientific and technological challenge. Debates about the possibility of conscious robots and the related positive outcomes and hazards for human beings are today no more confined to philosophical circles. Robot consciousness is a research field aimed to a unified view of approaches as cognitive robotics, epigenetic and affective robotics, situated and embodied robotics, developmental robotics, anticipatory systems, biomimetic robotics. Scholars agree that a conscious robot would completely change the current views on technology: it would not be an “intelligent companion” but a complete novel kind of artifact. Notably, many neuroscientists involved in the study of consciousness do not exclude this possibility. Moreover, facing the problem of consciousness in robots may be a major move on the study of consciousness in humans and animals.

The Frontiers Research Topic on consciousness in humanoid robots concerns the theoretical studies, the models and the case studies of consciousness in humanoid robots. Topics related to this argument are:
– the needs of a body for robot consciousness;
– robot self-consciousness;
– the capability of a robot to reason about itself, its body and skills;
– the episodic memory in a robot, i.e., the ability to take into account its operational life;
– design strategies versus developmental approaches in assessing consciousness in a robot;
– robot architectures candidates for consciousness;
– symbolic versus neural networks representations in robot consciousness;
– consciousness, theory of mind and emotions in a humanoid robot;
– measurements and assessments of consciousness and self-consciousness in a robot;
– ethical and trust issues in a conscious humanoid robot.

The agency of objects

An interesting take on the agency of artifacts in light of the discussion of memes and temes. From Sinha, S. (2015). “Language and other artifacts: Socio-cultural dynamics of niche construction.” Frontiers in Psychology.

“If (as I have argued) symbolic cognitive artifacts have the effect of changing both world and mind, is it enough to think of them as mere ‘tools’ for the realization of human deliberative intention, or are they themselves agents? This question would be effectively precluded by some definitions of agency […] In emphasizing the distinction, and contrasting agents with artifacts, it fails to engage with the complex network of mediation of distinctly human, social agency by artifactual means. It is precisely the importance of this network for both cognitive and social theory that Latour highlights by introducing the concept of ‘interobjectivity.’ […] Symbolic cognitive artifacts are not just repositories, the are also agents of change. […] We can argue that the agency is (at least until now) ultimately dependent on human agency, without which artifactual agency would neither exist nor have effect. But it would be wrong to think of artifactual agency as merely derivative.”

The Third Way of evolutionary biology

Interesting website on this innovative exploration of the field. From the link:

“The vast majority of people believe that there are only two alternative ways to explain the origins of biological diversity. One way is Creationism that depends upon intervention by a divine Creator. That is clearly unscientific because it brings an arbitrary supernatural force into the evolution process. The commonly accepted alternative is Neo-Darwinism, which is clearly naturalistic science but ignores much contemporary molecular evidence and invokes a set of unsupported assumptions about the accidental nature of hereditary variation. Neo-Darwinism ignores important rapid evolutionary processes such as symbiogenesis, horizontal DNA transfer, action of mobile DNA and epigenetic modifications. Moreover, some Neo-Darwinists have elevated Natural Selection into a unique creative force that solves all the difficult evolutionary problems without a real empirical basis. Many scientists today see the need for a deeper and more complete exploration of all aspects of the evolutionary process.”

Homo deus

Power Valued Over Truth

Dear Ed and All,

“We are the ones that create human nature by inculcating cooperation and care over selfishness and power.”

The view you express, Ed, contesting Harari’s claim in Homo deus, seems to edge up closely to the “pre-modern” standard social science of model of human nature, i.e., that it is almost solely a product of culture, with no or minimal influence of naturally selected genes and very fancy naturally selected epigenetic mechanisms for gene regulation. It is the idea that we pretty much are born, mentally, a blank slate. That is demonstrably wrong. There is a deep and mighty pan-cultural, species-typical human nature that impacts all our intrapsychic life and behavior. It is designed only to be impacted in very specific and limited biologically fitness-enhancing ways by local cultural influences. Harari is correct, at least in the sense that our basic nature is only contingently to value truth, that is, only to the extent that it increases our power to generate greater lifetime inclusive fitness.

Yet, and here is where you and I can find, IMO, great and expansive common ground, natural selection in our species created a mind designed to compete in complex multi-partner, multi-currency socioeconomic bargaining, and thus for status (i.e., power), with great acumen, during an ongoing intraspecific arms race with other humans, including close social partners, over the last several hundred thousand years. Importantly, non-trivial metacognition and mentalization (theory of mind) capacities evolved as part of our package of competitive cognitive capacities; these can be used to evaluate, predict, and manipulate others, and to observe and study ourselves. Imaginative capacities and an ability to believe deeply in both fantasy and evidence also evolved to allow us to cohabit “adaptively subjective dreamworlds” (ASD) that hold human groups together. For example, one example of a written down, very dear and pretty darn auspicious ASD is the US Constitution.

Natural selection has zero foresight. This is the only reason we have any chance of beginning to alter how our minds operate. Down the road, once some leaders develop the capacity to make good decisions about how to genetically modify ourselves to be more compassionate and sustainable, probably with the help of evolutionary psychology, a massive program of intentional genetic evolution may be what’s really necessary to get us through our current very dangerous technological adolescence.

Robust, transparent (nonconscious), sly and clever neurological regulatory mechanisms assuredly have evolved to more or less (denoting very slight individual variation in brain development) lock us into making effective and efficient (i.e., powerful) use of our outstanding cognitive abilities to maximize lifetime gene propagation, whether we know this is what we are up to or not.

Yet, this same program of natural selection, epiphenomenally, gave all or most of us the potential — almost always hard won and seldom truly accessed — to employ evolutionarily novel intrapsychic maneuvers, learned from our most sophisticated ancestors, to weaken or “get ahead of” the above-mentioned regulatory mechanisms. Here I am referring to introspective techniques that help us see our own mental operations more objectively, not techniques that just lead to relaxation or greater happiness. This unnaturally objectified seeing can happen in real time (best) or during reflection upon past events (dicey).

An analogy, accidentally constructed by the Wachowskis (?), for using the introspective techniques I’m referring to is vividly given in “The Matrix” trilogy, when Morpheus and his team, eventually especially Neo, purposely send their minds into the matrix via skillful intrapsychic hacking procedures. They are not going in there to sunbathe… even though that would be nice. They cannot. The regulatory mechanisms that already are in place are quite, albeit imperfectly, adaptive in real time. They have the ability to learn. They are seldom are far behind and their prime mandate is to encapsulate or literally destroy the complex neural circuits (i.e, symbolized by Matrix characters like Trinity, Morpheus, Mouse, Sipher) that may collaborate to enable biologically subversive attempts at gaining deep objective self-knowledge. These regulatory mechanisms are key to biologically adaptive neurodevelopment, and they are extraordinarily resourceful and ruthless. They may be limbically based, but any part of the brain can be recruited to help them fulfill their mission, as was “The Matrix” character Sipher.

My own mind largely has been ruined, I feel, by engaging in this process. A lot of my essential “freedom circuitry” has been repeatedly hammered. But, I still believe success is possible for some, particularly if they can learn from the mistakes and rare successes of others. Call it faith in consciousness.

A new analogy has hit me. We are born into a cognitive-emotional prison cell full of delights as well as sources of suffering. (As per astute Buddhist teachings, it’s really all suffering.) But, we may notice that hanging from the ceiling, outside the cell bars but more or less within reach, there are various sets of shiny keys. Usually, one of them opens our cell door. Others keys in the set open additional doors spread throughout an unknown intrapsychic labyrinth. Opening some of those doors triggers an instant alarm, others a delayed alarm, maybe others no alarm at all, especially if the key is inserted and turned correctly. Some sets of keys open doors that lead to traps and cul-de-sacs. You can easily end up in a seemingly nicer jail cell. Or a worse one. Perhaps you can end up in enticing cells, but with no keys hanging outside the bars. It may be hard to tell if one has progressed in any meaningful way.

A legitimate teacher, or cultural tradition, and/or a modern scientific tradition may help us learn something of the labyrinth, and which set of keys to pick that lead to real freedom, or at least time-limited degrees of it. We can learn to go farther and farther.  But the prison is larger and more complex than we typically can conceive, especially anywhere near to our starting position, and especially if we try to do so alone.

Perhaps the best path is right around a nearby intrapsychic corner. But if anyone tells you so, beware. — Paul

PS: I’ll try to post this on our web site, since it took a couple hours to write, and may have some value for our upcoming discussion(s).

The evolutionary and present significance of reading

In her new book, Reader Come Home: The Reading Brain in a Digital World, author Maryanne Wolf explores how reading affects the brain and mind. What different effects result from consuming digital media rather than print media and long forms rather than tweets, posts, and other microcontent? In her excellent recent article, she says,

Will new readers develop the more time-demanding cognitive processes nurtured by print-based mediums as they absorb and acquire new cognitive capacities emphasized by digital media? For example, will the combination of reading on digital formats and daily immersion in a variety of digital experiences — from social media to virtual games — impede the formation of the slower cognitive processes, such as critical thinking, personal reflection, imagination, and empathy, that are all part of deep reading?

Wolf first addressed the evolution of reading and its implications in her earlier book, Proust and the Squid: The Story and Science of the Reading Brain. She summarizes her thesis in this interview (14 min video).

Stanislas Dehaene, an author whose work we’ve discussed, also investigated the brain circuits involved in reading. Hear him speak on the topic in this video (33 min).

From computers to cultivation

Another article Sulikowski referenced, highlighting the debate between the computational and 4E models. Therein it notes that the computational approach is akin to Chomsky’s computational linguistics. Note that Lakoff broke from Chomsky on this and went on to formulate embodied linguistics. It appears this debate is an ongoing battle in different fields. The abstract:

“Does evolutionary theorizing have a role in psychology? This is a more contentious issue than one might imagine, given that, as evolved creatures, the answer must surely be yes. The contested nature of evolutionary psychology lies not in our status as evolved beings, but in the extent to which evolutionary ideas add value to studies of human behavior, and the rigor with which these ideas are tested. This, in turn, is linked to the framework in which particular evolutionary ideas are situated. While the framing of the current research topic places the brain-as-computer metaphor in opposition to evolutionary psychology, the most prominent school of thought in this field (born out of cognitive psychology, and often known as the Santa Barbara school) is entirely wedded to the computational theory of mind as an explanatory framework. Its unique aspect is to argue that the mind consists of a large number of functionally specialized (i.e., domain-specific) computational mechanisms, or modules (the massive modularity hypothesis). Far from offering an alternative to, or an improvement on, the current perspective, we argue that evolutionary psychology is a mainstream computational theory, and that its arguments for domain-specificity often rest on shaky premises. We then go on to suggest that the various forms of e-cognition (i.e., embodied, embedded, enactive) represent a true alternative to standard computational approaches, with an emphasis on “cognitive integration” or the “extended mind hypothesis” in particular. We feel this offers the most promise for human psychology because it incorporates the social and historical processes that are crucial to human “mind-making” within an evolutionarily informed framework. In addition to linking to other research areas in psychology, this approach is more likely to form productive links to other disciplines within the social sciences, not least by encouraging a healthy pluralism in approach.”

Extended evolutionary psychology

Article by Stotz (referenced in the last post), Frontiers in Psychology, 20 August 2014. This one is a bit more like Thompson’s approach. The abstract:

“What kind mechanisms one deems central for the evolutionary process deeply influences one’s understanding of the nature of organisms, including cognition. Reversely, adopting a certain approach to the nature of life and cognition and the relationship between them or between the organism and its environment should affect one’s view of evolutionary theory. This paper explores this reciprocal relationship in more detail. In particular it argues that the view of living and cognitive systems, especially humans, as deeply integrated beings embedded in and transformed by their genetic, epigenetic (molecular and cellular), behavioral, ecological, socio-cultural and cognitive-symbolic legacies calls for an extended evolutionary synthesis that goes beyond either a theory of genes juxtaposed against a theory of cultural evolution and or even more sophisticated theories of gene-culture coevolution and niche construction. Environments, particularly in the form of developmental environments, do not just select for variation, they also create new variation by influencing development through the reliable transmission of non-genetic but heritable information. This paper stresses particularly views of embodied, embedded, enacted and extended cognition, and their relationship to those aspects of extended inheritance that lie between genetic and cultural inheritance, the still gray area of epigenetic and behavioral inheritance systems that play a role in parental effect. These are the processes that can be regarded as transgenerational developmental plasticity and that I think can most fruitfully contribute to, and be investigated by, developmental psychology.”

Evolutionary theory: Fringe or central to psychological science?

By Danielle Sulikowski in Frontiers in Psychology, 24 May 2016. From the conclusion:

“Newer conceptualizations of EP are uncommitted to notions of massive modularity, look beyond the Pleistocene for the selection pressures that have shaped psychological mechanisms and incorporate developmental and cultural impacts into theories concerning the evolved functions of psychological mechanisms. It is clear however, that the massive modularity roots of modern EP still influence how many, including both advocates and critics, view the field. One message that is clear from the works presented in this volume, is that EP must mature and free itself of many of its early assumptions and assertions (as seems to be currently happening empirically, if not yet theoretically, Burke). Only if this occurs, will EP be placed to properly integrate with Evolutionary Biology and be in a position to cement evolutionary theory as a unifying meta-theory for Psychological Science. Whether such a New Evolutionary Psychology should incorporate computational theories of mind or reject these in favor of the newer e-cognition perspectives is an empirical question and not one whose answer needs to be decided before the weight of evidence has settled in either court (Stephen).

E-cognition is defined as “extended, embodied approaches which place emphasis on the role played by the whole organism and its environment in the decision-making process, rather than simply the brain.” Some examples are is Stotz’s extended evolutionary psychology:  “Combining evolutionary theories concerning genetic, epigenetic, behavioral, and cultural systems of inheritance, developmental plasticity and niche construction, with e-cognition, Stotz outlines a truly integrative EP.” Barrett and Stulp et al. argue for the extended mind hypothesis which “places much emphasis on the sociocultural nature of human psychology and the external resources (cultural and technological artifacts) that form part of the modern human cognitive system. The Extended Mind Hypothesis offers the various forms of e-cognition, rather than EP, as the appropriate meta-theoretical perspective to succeed the computational theory of mind.”
