First conference talk and proceedings publication!

Going to CogSci17 in London this summer for my first research presentation, the paper is to be published in the proceedings (and can be found here). Here’s the abstract:

The actualization of affordances can often be accomplished in numerous, equifinal ways. For instance, an individual could discard an item in a rubbish bin by walking over and dropping it, or by throwing it from a distance. The aim of the current study was to investigate the behavioral dynamics associated with such metastability using a ball-to-bin transportation task. Using time-interval between sequential ball-presentation as a control parameter, participants transported balls from a pickup location to a drop-off bin 9m away. A high degree of variability in task-actualization was expected and found, and the Cusp Catatrophe model was used to understand how this behavioral variability emerged as a function of hard (time interval) and soft (e.g. motivation) task dynamic constraints. Simulations demonstrated that this two parameter state manifold could capture the wide range of participant behaviors, and explain how these behaviors naturally emerge in an under-constrained task context.

Keywords: affordances, dynamic systems, cusp catastrophe, dynamic modeling, simulations, constraints

En dag till.

Sanningen är ibland, och på vissa nivåer, ganska simpel. Vi alla har känslor, får känslor, känner känslor. Det är också sant att vi ibland inte agerar på våra känslor, men vi bär de med oss. Vi släpper ut de på ett eller annat sätt, för i slutändan är vi inte så annorlunda från resten av den fysiska världen. Om där finns en koncentration av energi någonstans i jämförelse med miljön den befinner sig i, så finns där en spontan process som alltid strävar efter att jämna ut den skillnaden. Jag tror alltså att våra känslor är och fungerar i generell bemärkelse som vilken annan fysisk process som helst. Ett varmt glas i ett kallt rum, över tid jämnar temperaturen ut sig. Ilska, som vi kan släppa ut destruktivt genom aggressivitet, i ett slag, i ett ord, eller många små. Naturligtvis har denna analog en gräns, men det är en början till att bygga en bro mellan det oerhört svårt tekniska Dynamisk System Teori/Komplex System Teori till alldagligt tal och alldagliga händelser.
 
Ett är säkert dock. Vi måste börja lyssna på varandra, förstå varandra, låta varandras känslor ta plats, men även föra dialog och komma till kompromisser -ibland hårda och ibland mjuka. Vi måste förstå att vi inte kan använda våra känslor som vapen, utan istället som verktyg, för att förstå oss själva lite bättre, för att kunna navigera världen lite bättre. Om du blev förnärmad eller kände dig kränkt, hur kan den känslan påverka vad och hur du kommunicerar det tillbaka? På ett konstruktivt sätt? Att göra det på ett destruktivt sätt kan ge dig en skön vendetta, men i slutändan brukar det bara leda till mer av det som du reagerade på från första början. Du kanske inte hör det, men nästa person gör.
 
Vi måste också börja förstå att världen omkring oss inte går att dela upp i två alltid. Vi har kompetens till så mycket mer än så, till bara en lite, lite mindre simpel världsbild. Kan vi det, så kan vi förändra måendet hos en stor mängd individer som just i denna stund övertygar sig själva att, till exempel, inte ta sitt liv. För att, för vissa, så omvandlas känslor automatiskt till en självreflektion. Du är dålig. Varför fortsätter du? Förstår du inte att det inte finns hopp för dig?
 
Just därför är det så otroligt viktigt att visa andra att det finns en plats för de också. Att de inte är utanför samhället, att de inte är så annorlunda ändå, att de inte behöver passa in i samhällsnormer för att känna acceptans från sin omvärld. Att känna tillhörighet, på sina egna villkor, är en stark förbindelse till omvärlden. Du kan ge det till någon. Kanske inte fullt ut. Men lite. Bara så lite som kanske just behövdes den dagen, för att få just det där lilla ljuset djupt inom sig att flämta till. En dag till. En dag i taget.

…an old Radiolab episode about AI and assumptions about humans.

One of Radiolab’s older episodes “Talking to Machines” talks about programs that try to simulate conversations. The classic Turing test is that if you are speaking to a robot and a human, and you cannot determine which is human or which is a robot (or getting the classification wrong) then the robot/computer can be said to be intelligent.

Now, I would love to argue a different definition of intelligence, but that isn’t really what this post is about. One of the conclusions from the owner of Clever Bot (a fascinating program that saves whatever you write to it and then is coded to spit back a correlated response -from the pool of existing phrases) is that thinking intensely about AI and conversations is how complex it is to sit in front of one another and have a conversation. The reasoning goes, because it is so difficult to code a program to converse ‘like a human’, then our “coding” must be complex also. It falls in line with metaphors about the brain, giving it ostensible plausibility.

However, haven’t we reversed the reasoning here? Aren’t we assuming in the first place that brains/humans are computational machines, and so it should be possible to code a program for something humans do? It started out the opposite… That we were trying to have the computer behave like a human, not the other way around! Could it not be so that coding a program to converse ‘like a human’ is so difficult, because humans actually aren’t like computers?

If humans aren’t computational machines, then trying to code a program for something that isn’t written as “software in our brain hardware”, is going to be very difficult indeed. But going from the latter to the former is a potentially fallacious way of thinking about it. You could even make the case that conversations aren’t that complex… After all, they are wholly ubiquitous in our everyday lives! We might argue that there are successful and failed conversations, but I’d say they are conversations nonetheless, and very human.

Reproducibility in dynamic systems

What does it mean that something is easily reproducible?

It speaks to the stability of the processes and constraints on which the dynamic system in question relies on for its existence.

Reproducibility or recreation (or whichever other term you may want to use for the creation of something already existent, by itself or its scaffolded/nested position) could possibly be used as a measure of something’s existential stability. For example, the survival of a language depends on many individuals speaking the language, a shared geographical space wherein the language is spoken as well as a social context/culture (or perhaps rather, all together a system of mutual support and constraint).

Uttering the words of a language you have grown up in requires little energy (whereas the history of that word involves massive amounts of energy, the word is essentially a concentrated unit of historical energy expenditure -and it is from this history that it has gained its efficiency [or meaning, or …]). That you are able to say some specific word with ease and it is understood clearly, speaks to the underlying processes’ incredible stability (from which that word has sprung from and is maintained by). Or imagine DNA.

The links between ease of reproducibility, the large amount of work produced to enable its creation as well as the amount of stability over time in its underlying processes -explains the history and maintenance of any given phenomenon.

The ontological status of affordances…

…only exist when they are being actualised and/or are being realised. It is not that they do not exist when not, there always exists the information of -but until this information is picked up, they practically do not exist.

Information, independently exists. It exists for so long as there is a source to “illuminate” it: The sun shines, and other stars shine, and only if the source of photons cease to exist, shall the visual information that the visual systems of life forms do not have even the possibility of detecting it.

While information is not “what we see”, affordances are (often based on the middle-hand of medium-sized objects if our visual system is unaided). I guess you could say that objects are made up of information, but I’d be hard pressed to agree to this articulation in a strict scientific sense, it’ll do to make the point clear however. Affordances, being relationships between (for this example’s sake) properties and objects of the environment and the capabilities and effectivities of a human, seem to be able to not exist.

If we are in a room with chairs in it, and we leave the room, the chairs in the room still offer the affordance of sitting if we were to observe the room through a camera (the realisation part). If no life form is in the room to detect the information of said chairs affording sitting, then the affordance is what I’d like to call passive (or let’s say, doesn’t practically exist). It’s ontological status is pending a life form able to perceive the information of and act in accordance with, the affordance.

[Start Edit]Think of it as an establishment of any kind of relationship. Before one has been perceived/realised by anyone, there is a flux of information to be discovered and there is a non-relationship. Once discovered however, that relationship most probably cannot be undone. It reminds me of the very dramatic difference between not being able to not perceive the relationship when it has been established once, compared to when it is either just perceived or when we have yet to discover what type of relation we have/can have to it.

Is this problematic? I don’t think so. On the level of information, it must still exist. On the level of affordances however, it cannot. This is not problematic since nothing is going in and out of existence, but, the relationship between environment and actor necessarily incorporates both and is temporarily suspended -it is inactive, or passive. Innovation and creativity is sometimes defined as the discovery of new ways to relate to existent (or new) objects, properties, life forms, ourselves, etc…[End Edit]

Is this important? Perhaps not. However, ontology is important in a general sense. I think it necessitates at least a mention in a blog post, in a galaxy, far, far away.

An ecological note on the Müller-Lyer illusion

The Müller-Lyer illusion

Are one of the lines longer, shorter or the same length as the other one?

Traditional psychology holds that perception is flawed, we see illusions because the underlying perceptual aspects of our experience need to be embellished, corrected, interpreted, etc, by our brain. While doing this we make mistakes. It is often posited as one of the major issues for ecological psychology to explain because it seems to invite cognition. After all, if all the information is detectable out in the environment, then why would we perceive the top line as shorter and the bottom one as longer?

Perceptual illusions in real life (not on paper or a screen) can quite easily be dealt with. We could argue that the we have not sampled enough of the available information in the ambient optic array, so we do that by locomotion and change of viewing angle. When we do, very many illusions are simply dispelled (Kennedy & Portal, 1990, or Michaels & Corello, 1981). In fact Michaels and Corello explains this very well; if we are in a desert, looking for water and see a mirage (which may or may not be water), it is right of us to investigate if it is or not, not doing so would be the wrong action to take. In the same way, they exemplify, could we be fooled by a hologram until we reach out to try and touch it.
Besides this point, the illusions that aren’t able to be dispelled by simply exploring, are always images or videos on a screen or paper. Making them in part unexplorable. As for the Müller-Lyer illusion, it is at the same time simple but abstract forms. All the information given is what is there, but even looking at it now, knowing they are the same length, I still perceive them as different lengths. A solution that has been suggested elsewhere (lost the reference sorry) is that the top figure shows an enclosing space, if we were to reach our hand in, we would be more constrained than the bottom figure. The information is specifying a smaller versus a larger space.
Another assumption of traditional psychology is that (visual) perception works with the simplest aspects, lines, points, and that then there is a constructive process cognitively that puts things together into more and more complex constructions of what we perceive (into the full 3d-experience of the world). For a traditionalist then, there is no doubt it is an illusion, the lines are the same length, we perceive them to be different -our brain is playing tricks with us. From an ecological standpoint, it is impossible not to see the four end lines, you can’t not perceive them when perceiving the end of the lines. Therefore, they matter.
It is fully possible that we actually don’t perceive the “simplest” form and construct it, in fact, this is what ecological psychology says we don’t do. The example comes from the Planimeter (Runeson). A mechanical, simple, device that can measure the area of irregular patches without knowing length, width or doing any computations. (For its full explanation, see here.) It thus measures a “higher order” thing, sqaure cm (or inch) without the “simpler” concepts. It is fully possible to conceive of the idea that we then simply cannot ignore the four end lines -they are not individual lines, they are a form that is important, in it’s whole, to our perception of it. For this reason, it may just be so that the question “Are one of the lines shorter, longer or the same length as the other?” a silly question to ask. Because our perceptual system does not work on simple structure and construction, it is forcing us to do something that we simply don’t do, and therefore do it poorly.
(Which unfortunately is not too uncommon in the traditional psychological literature.)

Is it an impossibility to “see” the Big Bang?

Even if we theorise there to be a universe contracting and expanding, or a Big Bang, it might be impossible to actually “see” it. The reason would be found in Ecological Psychology.

Only when Ambient Light has structure does it specify the environment. There has to be differences in different directions, for it to contain any information. Perfect symmetry, maximum entropy, is theorised to be a whole bunch of homogeniety in layout, distance between particles, etc. If we have a medium that is perfectly evenly distributed, we do not have difference. So how could we ever “see” it?

Emotions are Internal Potentials, Self-Organising Behaviour after Reaching (organism specific) Thresholds

As a system, there has to be a continuously reproducable heterogeneity of processes, for there to be an emergent level (a system) from it. The only difference between animate and non-animate things, is that animate things continue to produce stably reproducible homogenous levels (by heterogenous sub-processes). Non-animate objects can only create homogenous processes, more of the same, unless they increase into vast sizes (which means they are not unimportant because they have consequences for possible interactions in lower levels, like gravity being a prerequisite of biochemical organisms). When the interaction is reproduced over time however, the emergent level becomes less temporary. The emergent level needs to be reproduced homogenously over time, i.e. the consequences of a heterogenous system needs to be homogenous. Constraints, and laws, ensure this to be the case (stochasticity under laws). For example, gravity is stable enough through both space and time on earth to sustain life to develop further. Thus, a system like a human being needs to be able to reproduce work to survive, but perceiving a human (the system) as a unit, its constituent parts need to be heterogenous. This entails that otherwise no “internal” (to the system) difference can be created, nothing to drive the system.
When it comes to humans, I believe “emotions” drive our system. They are field potentials contained through (not in) our body. The experience of emotions, their phenomenology, is different to what I mean by “emotions” in this article (make no mistake that these thoughts are founded on direct perception, although this doesn’t necessarily has a bearing on “emotions”, we are still far away to hypothesise differently though). Let’s assume that our experience of the world simply is the continuous flow of collective (all senses) perception of the world, we perceive the world directly (in the philosophical sense) but propagation through our body (whatever, after we understand the specificity of direct perception, may end up being “in” us) takes time. Thus, and also traditionally, our experience of “emotions”, can be a part of the perceptual online flow and experienced as emotions.
“Emotions” are the driving forces of any biochemical thing (or organisms). “Emotions” are the consequence of Direct Perception and Acting in the world (as well as the history of previous DP and A). They are the internal force acting on the system to create difference –and in the continued propagation, creates an autocatakinetic system around the initial force. This means that forces can have graded impact on us, and if weak and not reproduced over time, simply abates. If reproduced, resulting in build-up of impact, or if the force is strong to begin with, it then forces an “internal” difference, creating an autocatakinetic system around it and becoming the internal force acting continuingly back onto the system. These “internal” potentials can be abated by producing work (herein is defined as body movement [muscle movement by limbs, body and/or face {including the vocal tract}] and biochemical compounds [saliva, sweat, excrement, etc]). One point is that this means I believe emotions act as the threshold for human systems to self-organise into different behaviours. Another point is that our body is a less temporary process (a structure) and as such biochemical energy can hold some energy through it’s physical matter. While some of the entropy produced by work, leaves the body as heat, some of it is kept within the system. It acts on the system (metaphorically) as a weight, which we can withstand for a certain amount of time. Build-up of entropy, stored entropy, is the entropy debt in the body. However, when entropy debt (the entropy stored through, not in, organismic structure) reaches a threshold, organisms need to rid themselves of it.
Bertalanffy and Schröedinger emphasized that as long as an autocatakinetic system produces entropy fast enough to compensate for its development and maintenance away from equilibrium (its own internal entropy reduction) it is permitted to exist.” -Swenson

When entropy debt is massive, we have to produce work or ingest chemical compounds to keep energy propagating in our systems. However, when entropy debt increases past our capability of producing work to maintain it, we undergo a period of involuntary torpor (physical and mental lethargy). When entropy debt is simply at the amount of work we produce during a relatively normal day, it is enough that we lower our energy propagation (become calm) enough to lower our produced work (and energy propagation) underneath the level of entropy debt, to fall asleep. Lower amounts of entropy debt can be ridded by resting. Entropy debt has to be repaid. It does so by forcing us to rest (no matter our attempt to avoid it). In fact, without REM sleep, we risk our life.
Why do we sleep? Because we need to repay entropy debt. Perhaps it could be argued that even the small amount of control (free will) that we (might) have, needs to be surrendered temporarily for us to repay the debt automatically created solely by our existence (maintenance away from equilibrium). Not repaying entropy debt results in the degrading of our physical matter –as a course of life, this will happen at any rate since all physical matter simply are temporary processes, affected by the energy that runs through them (biological, chemical or physical). But we can affect it. As a simple example, for a human; food, sleep, exercise and social interaction are vital. Specific foods can increase specific compounds in our body, for example fat intake, that make previous energy propagation require more work. Or sleep deprivation does not allow us to rid ourselves of entropy debt. In many different ways we can affect propagation of energy, intake and ridding ourselves of entropy debt. If not (except obvious health side-effects) our structure (less temporary process) gets ‘damaged’ -moves toward disorder. And it does it in specific ways, for example, by telomere shortening (but there are a couple more specific biological consequences). (This is also a reason why there isn’t a one-fix-all for aging.) However, we can never stop aging completely, this is due to our physical make-up and the necessary energy propagation through it which, given time, will always lead to higher rates of disorder. We can however affect the rate of disorder.
In short, my hypotheses are that a) emotions are internal potentials, b) they create an autocatakinetic system around their initial internal force, c) reaching an emotional threshold self-organises behaviour, d) entropy debt in human systems is ridded by rest, e) non-ridded entropy debt damages the human system, f) we can never completely hinder damage, g) we can affect how much work energy propagation requires, and h) we can affect how much entropy build-up we can withstand (without damage).
I suspect this list of hypotheses will be added to and detracted from, those who overcome entropy debt shall see.

Why humans prefer symmetry

A highly symmetrical face leaves little work needed to be produced by the perceiver. The perceiver essentially does not find “obstacles” in what hie perceives, which has the inherent property of requiring less work. Not inciting work keeps the perceiver’s synchronisation with hier’s environment stable -there is no perturbation and consequently no change. This non-change then is experienced as trygghet (safety, security, trust). Trygghet being a basic human need means it will be preferred.

A definition of endeavors in personality.

I want to apologise outright. I couldn’t help myself when reading Linda Smith’s chapter on “More than concepts: How multiple integrations make human intelligence”. There is a section describing an experiment where an infant’s feet are tied to a mobile above its crib and it reminded me of my beliefs about the construct of personality. Again, I do apologise, please take in jest. Original text first, Personality afterwards.
