I am in the process of writing up my master thesis experiment but can reveal that in this specific task, participants use ecological strategy 53% of trials, computational strategy 26%, a second ecological type strategy 13% and other/non-distinguishable 8%. Also, accuracy is higher when using ecological strategy (63%) compared to computational (32%) and the other two. Inter-rater reliability ~.85. Exciting! It may support the ideas that screen-based research can indeed yield empirical results in Ecological Psychology (and add to that, in favour of Ecological Psychology). I have however yet to analyze the data statistically, to be continued!

Disappointment as a consequence of EP. Good riddance, I say.
I believe many will be disappointed to find out that there is no entity called consciousness. There is no entity called self. There is, in fact, nothing of any of this kind. All there is is a half-assed semi-reproduction of sensory input. Reproduction here almost misleads one however, it is not production, it just is perception. Conscious cognitive acts, just are perceptions. There is nothing over and above perception to be had. Creativity is just the rearrangement of perceptions. Imagination is just the semi-production of perceptions.
Our brain doesn’t store anything in that sense, it is solely repeated exposure to specific parts of the ambient energy array, allowing perception to continue past the now and lend itself to re-perception without the need for the concurrent exposure in the environment. It solely speaks to the persistence of environment, objects and agents. We are truly active explorers, and what we explore the most, we become able to more so specifically explore. It is about perceiving what is there to be perceived, what was there to be perceived before but because of repeated exposure we are more and more able to discriminate between smaller and smaller changes in that ambient energy array. Indeed it is what experience is. Perception and movement is all there is. “All”. It gets us very far.
Perceived sense of control, is just that. Perceived. Ecological Psychology or rECS leads to discussions on free will, and rightly so. Many proponents of free will argue that we need it to be able to be held accountable for offenses. I argue we still can even without. It is enough that we perceive our actions to be of free will, it doesn’t have a bearing on the metaphysical account of free will. As long as humans experience the world as if we control our actions in it, we can still be held accountable.
Unofficial lecture on representations, intro to rECS and Master Thesis
So I’m writing my thesis on abandoning representations and replacing it with ecological psychology, and this is bits and pieces of what I’m writing. To fit one lecture I obviously had to leave out a whole lot of information. Even information that would change some of the subject matter. The idea I had was to introduce, not even all of, the basic stuff I have in my thesis and was hoping to get some critique and comments on it.

Virtual affordances. Electronic Sports (and Computer Resistence).
I’ve grown up with computers since birth, in fact, one of the first generations to do so. The virtual world needs to be accounted for, but I accept the non-affordance of pictures, depictions, movies and thus screens overall (but see http://psychsciencenotes.blogspot.co.uk/2013/04/the-information-available-in-pictures.html for very recent, in-depth, information) I believe it is enough to denote this with the word virtual. This is something I go to some length with in my thesis and the beneath is the preliminary version of that section. While there is some revision still to take place, the main content is there and should provide enough clarity as to what I mean by it.
The world of electronic sports (henceforth; e-sports) is a largely unexplored area even within traditional cognitive psychology. In rECS it is discounted, essentially, because it is performed on a screen and as such does not provide affordances per say. In agreement with this, you still cannot just ignore this massive field. It is not only entertainment, it is for some a way of life and it is for others their monthly income -both as creators as well as players. In an attempt to refrain from legitimising the field further, it stands for itself in the amount of hours played, the number of games produced, the amount of profit for gaming-companies and the prize-pools for e-sports players. One aspect however, that is unstated in the relevant literature, is that unbeknownst to producers and programmers of games, their absolute central aspects, follow exactly that of ecological psychology and rECS. Gibson (1986) made the same analogy, however with greater depth, for the fields of architecture and design.
A programmer creates the environment in which a player is to exist and, hopefully, immerse herself. The virtual environment is created in respect to contain virtual affordances for the player, or for the player to explore and act within. The evolution of computers, as well as the games played on these computers, have increasingly dealt with the fact that players expect more and more virtual affordances to be available to them. There is an expectation to be able to do more things, to increase the complexity of the virtual environment, virtual objects and other virtual agents. When expansions are released for already popular games, they account for this fact by not only adding new items, for example in MMORPGS (massively multiplayer online role-playing games), but also by creating new virtual affordances to players through new game modes (changing virtual affordances of the already known game), allowing completely new virtual behaviours and thus making the virtual environment increasingly complex. For games that insist on reflecting reality, the expectation is that virtual affordances should more and more closely resemble the environment. This is thus an essential area to account for when it comes to rECS and psychology in general. It is necessary however to introduce the term virtual affordances, because as stated, pictures, depictions and even movies do not present affordances (Gibson, 1986 and Wilson & Golonka, 2013). Nevertheless, computer gaming industry works with manipulation of virtual affordances, and thus, virtual affordances are defined as invariants programmed in environment, objects and agents, allowing, limiting or disallowing virtual behaviours, interactions and coupled systems between those environments, objects and agents.
The game of choice for exemplification, is League of Legends (launched 2009, by Riot Games, formed in 2006). It is played by 32 million unique players every month, 12 million of which play daily, racking up 1+ billion hours of play each month making it the most played computer game in the world (Riot Games, 2012). They have created a virtual environment in which there is an economic system; killing AI-agents and opponents grants money, from which you may buy items to further enhance your characters basic, level-dependent, properties. The virtual environment affords movement in two dimensions but also limits movement by walls and shrubbery. Each character, 110+ to choose from, is afforded five specific abilities (one passive, meaning it is not “usable” by pressing a button and four active abilities assigned to one key each) plus the choice of two out of thirteen that are common to all players. Some abilities modify movement capability of oneself, of other agents, amount of damage given, amount of damage taken and/or regeneration of vitals (health, mana or for a few characters, a specific other vital coupled to its offensive and/or defensive abilities). Two teams with five players on each team thus comprises (10*5*2) 100 agent-specific virtual affordances, coupled with the dynamic variety in which the virtual environment lends itself to each specific character. Needless to say, perceiving one’s own and other characters’ virtual affordances, in which sequence they are used, and in which situation, the dynamic relationship all these variables have in conjunction with where one is situated in the environment and your, and their, vitals, is what counts as skill in this game. It is a visual perception heavy game but auditory perception enables you to gain information on parts of the environment not currently in your virtual visual field but that may have an impact on your virtual behaviour. The mentioned variables are far from an exhaustive list; there are quite many more virtual affordances to be described, but these should be enough for even the most computer-illiterate to understand that it is far from a simple virtual environment to navigate through successfully. Thus, this complexity gives rise to a vast range of behaviours and emotions, one of the most extreme of which is called “rage-quitting”. It is when you are sufficiently angry, regardless of why, that you exit the game before completion and leave your team severely underpowered against the opponents. Similarly, it is what can be seen in real life interviews when interviewees physically leave the interview prematurely.
Computer-gaming, although not adhering to the strict definitions of rECS, needs to be accounted for and it is suggested that it is sufficient to discriminate between real life and gaming by the verbal notation virtual. When experimentally reporting on computer games or screen-dependent research, it is of great importance to include an exhaustive list of variables and virtual affordances in the previously mentioned task analysis. This leads on to the study at hand, where an attempt is made to follow this task analysis for rECS experimentation, in order to show its practical application; to try and create headway for computer-screen experimentation by refuting the unwillingness within the embodied perspective towards it; discriminate between predictive and prospective strategies in problem-solving to discriminate between computational and ecological strategies; and illuminate how lucrative future research can be on the basis of both the process under observation and, more generally, to produce knowledge about it through rECS.
Non-(?)necessary discrimination between actualisation and realisation
In Gibson’s perspective, are they not really the same thing? Perception in Gibson’s terms seem to imply that “acting on” is implied by perception. I am confused with how this unfolds in practice. Take the definition I outlined in a previous post, that realisation is the perception of a possible interaction as opposed to actualisation which is the instantiation of an interaction. Perception is interaction?!
I think of studies on mirror neurons (if they exist, if it is assumed they do not do what trad. cog. sci. say they do and instead are simple sensory modality + movement overlap/association -happenstancily, not predeterminally- neurons/cluster of neurons/areas) in that, ‘visual perception of’ and ‘engaging in’ is the same thing physiologically -since, as I suppose Gibson would have it, perception (regardless of which kind) includes oneself always. If one is not separated from the environment, then one perceives what others and oneself do as the same thing (obviously, humans distinguish between self and others, but, even then, not innately -which in itself doesn’t have to decide in the matter, but may inform). Maybe this could be seen as the process behind empathy or sympathy for example. I feel disgust if I perceive rotting meat, because perception is that of systems and parallel modalities and not separate “input pathways”.
They may however have a practical, communicationally, significant aspect to them since it makes it easier to explain perspective or experience of a situation in those terms. Though I also get the feeling that they refer to the false dichotomy of conscious/unconscious perception. Something superfluous to the ecological model. Indeed, it perpetuates the false assumption of consciousness per se. Note here however that “how we consciously experience” situations, is central to psychiatry, for example, and can be useful to navigate within in therapy. Experimental psychology however, should refrain from allowing this massive source of frame-of-reference error to guide theory too heavily.
Temporary conclusion on subjective/objective perspective and affordances (3/3)
I should stop writing “Temporary” in front of my titles. It should be presupposed that all theory is always temporary.
I may have gained an understanding leading on from the previous posts on subjective and objective perspectives, on the definition of affordances and perception, relating Gibsons ecological view with traditional philosophy and cognitive psychology.
As Gibson defines perception of the environment and oneself as the same thing at the same point in time, neither a subjective nor objective perspective discriminates between what is perceived and not. Both are perceived, always, for any point of location of observation. This is true for both an objective perspective and a subjective perspective. Since both are perceived, any concept related to perception will necessarily imply this conclusion. If one assumes a non-static observation point (as we almost never have a static one, we move), then the experience of perceiving affordances are of both environment and self always coupled, non-separable, always pointing in both directions. This conclusion is then perpetuated by direct perception.
The only issue I am facing with this is that when one wants to begin defining from a philosophical perspective, one immediately wants to ground theory in realism, inviting subjective and objective perspectives, mind-dependence and independence, since, it is a way in which we can discriminate between dualism and monism for one. Coming from a strictly ecological perspective, or perhaps, Gibsonian ecological perspective, and grounding theory from ecology, one does not need these perspectives since they do not discriminate between anything, they do not show any difference when either perspective is subsumed. It should then be for this reason that Gibson confuses me when he speaks of nothing being subjective nor objective or both, because the meaning of those perspectives do not have a bearing on experience or theory, i.e. change the perspective per se. They are presumably brought in because of tradition and norm, because they are words used widely in the classic literature -and are most fitting in philosophically (Hegelian argumentally) founded perspectives like traditional cognitive psychology.
Are affordances retained? 42.
You see, it doesn’t really matter. We are not in the area of discussing the physical world. We are not concerned with matter in the ontological sense at this point (although we, as written about in several previous posts, obviously take a realist stance if forced to define things in traditional linguistics and perspectives). The reason the answer is 42, then, is because we perceive and act in the “coupled” perspective (self & environment) always. We assume affordances are retained, that the ground affords walking if we should want to walk tomorrow on that surface. But the question is misleading, because it forces upon the answerer to provide an explanation from a physical perspective. It forces one to deal with terms in a traditional cognitive language. It forces discussion on words like realism, objective, subjective, memory (for past) and imagination (for future). When I am lead to believe Gibson would rather speak of perception, movement, senses and affordances.
Temporary conclusion on affordance definitions (my head will explode if I don’t give this a rest for a while). (4/5)
I’ve been entirely engulfed by ontology, epistemology and affordances the past days. My head is about to explode. But I’ve reached a temporary conclusion. A conclusion that is generally applicable, follow most of the “traditional” ideas from ecological cog, embodied cog and rECS. They depart in some aspects, but I believe them to be necessary to live up to the philosophical demands.
Affordances, need to be, or to be grounded in, [perceived]* physical properties. The reason I have is that there is no other possible way to define it without departing from realism. Please prove me wrong, I am staring myself blind at this.
Epistemologically, affordances are perceptible through information.
Information, [any] structure of [any] energy array (brilliantly defined by Sabrina Golonka)
Epistemologically, sensory modalities discriminate between and within structures.
Perception, “the apprehension of [information] where 1) the structure is specific to an event or property in the world, 2) where the meaning of the structure (for that organism in that task) is about that event or property (i.e., a dog’s bark is about the event of a barking dog), and 3) where the meaning of the structure must be learned (or, more correctly, where an organism must learn how to coordinate action with respect to this structure).” (stolen again from Sabrina Golonka).
Realisation, perception of affordances.
Epistemologically, perceiving information and coming to an understanding (need not be conscious, obviously… as if there is a black and white divide of conscious and non-conscious…) of some/all/the situationally relevant agent/objects’ affordances.
Actualisation, agent/object(s) affordance(s) interaction with agent/object(s) affordance(s).
Epistemologically, bodily movement between and/or within agents/objects affordances and can be either compatible (by the agent(s) affordances or by extension, like using a stick or something) or not (like lifting the earth, the earth does not lend itself to be lift-able).
Constraints, boundaries of realisation and actualisation.
Epistemologically, restrict compatibility of affordances between and/or within agent(s)/object(s). The knee does not afford the leg to bend backwards. A local constraint that has consequences for bodily movement in the global environment. Being dynamically coupled to environment/objects/other agents, constraints vary depending on the current situationally available affordances.
*Edit 25/3
Ontological and epistemological definitions of affordances (as per previous post). (2/5)
The ontology of affordances (based on my previous post), then, defines affordances as physical properties inherent to the object/agent that may be acted upon only by other compatible objects/agents.
The specific affordance to-be-explained is derived from the specific physical properties with the object/agent and they are necessarily constrained/restricted by both the body of the object/agent and the physical properties of the environment. For example, our legs are able to move in some ways but not others, we are restricted in the movement of our legs by a) the physical properties of the make-up of our leg (the knee puts the most obvious restriction) and b) the physical properties of the make-up of the environment in which it is currently in (living in a gas allows relatively free movement of the leg -compared to living in water, for example, but gravity will “restrict” -probably more accurate to say control here- us in one sense, whereas, say direct physical constraint -someone holding your feet down- restricts us in another sense). Here, thus, it should be obvious to see that Physics, Chemistry and Biology are necessarily implicated as the basis upon which determines what is a restriction and what is a constraint.
The most important part; defining affordances minimalistically ontologically, avoids many of the ontological consequences faced when defining affordances as relationships (by leading to some form of idealism), although, as I will argue, affordances within objects/agents depend on each other epistemologically. I believe this is also the consequence by using the definitions of realisation and actualisation for the epistemological reliance of affordances.
Realisation and actualisation is the, how we come in contact with, how we gain knowledge of, what affordances do. What we do. How we do them. Since (if I’ve got this right) (radical) embodied cognitive science posits that, consciousness, cognition, memory (and many other representationalist terms) are not properties of the brain -but things we do– then I think it appropriate to the central ideas of rECS. I use “radical Embodied Cognitive Science” instead of embodied cognition due to the well argued taxonomy that Chemero presents in his book. Radical does not get a capitol letter however, to make the point that the theory is not radical in and of itself (like Chemero argues) but is merely a distinction from Embodied Cognition. This distinction seems to me necessary because of Chemero’s arguments.
Affordances rely on the mechanisms of realisation and actualisation.
Realisation is to do with what Wilson & Golonka discusses on their blog, that which is perceptible necessarily contains information, if I understood it correctly (energy array etc., their definition is brilliant and me rewriting it would not do it justice, it also serves my purposes well).
Actualisation is to do with the coupling, when we act on the perceived affordances.
Objects exist when we are not there to perceive them; realisation, but not actualisation. It should be obvious that once we have perceived an object and some of its affordances, the realisation is retained by virtue of the compatible affordances of both the affordances of the object and the affordances of the agent. As of yet however, I believe the affordances of the agent are necessary (we can realise the affordance we need in an object in order to actualise the affordance perceived of our body).
Failing when doing; I don’t see this as an issue, why would it be? This type of reasoning belongs to Evil Philosopher type arguments, in that, because we “get it wrong” then it somehow reflects on the actual mechanism of perception and/or action. I do not believe this is so. Direct perception gives us the information that we are able to perceive and act upon, but in my mind there has to be a perturbance or something not yet perceived to disrupt our ability to actually carry out, actualise, affordances. And, objections like that seem to assume that we are perfect beings. As I see it, our sensory modalities are limited, we are not the pinnacle of “creation”, we will get things “wrong” -but like all other philosophy of mind objections it doesn’t have a bearing on ontology, solely epistemology. We evolved to perceive to survive and reproduce, not to gain a perfect perception of the environment. And that’s ok. Doesn’t have a bearing on affordances since they are defined ontologically without the requirement of being accurate.
Ontology; Affordances, thus, are not defined as realisation and actualisation, but as (simplified here) physical properties reflected by Wilson & Golonka’s definition of information.
Epistemology; Affordances rely on the mechanisms of realisation and actualisation. All three are necessarily constrained by physical properties of themselves individually as well as each other. Objects and agents can be realisable but not actualisable, both in presence and in absence of each other; actualisable only in presence of each other.
On the definition of affordances. (1/5)
This is most definitely a work under progress. These thoughts came from criticising Anthony Chemero’s “Radical Embodied Cognitive Science, ch. 7 “Affordances etc.” and concludes with the (in)famously ambiguous quote from Gibson on what affordances are defined as.
If affordances are defined as the relation between (or, the relation between is a part of the definition). Then an object need not exist if an agent is not perceiving it. It can, but it needn’t. This will incorporate idealism in full or in part and this is unsatisfactory.
If affordances are defined as the individual ability of an agent and the property of an object, then neither are necessarily coupled. Also unsatisfactory.
However, if abilities and properties are given a compatibility value (a, metaphorical, mathematical/numerical range), which, if in perception of each other are [also] within each others’ range and can thus be combined/actualised/realised. Then, if this is what we wish to call an affordance, is inherent individually in the object and the agent (and thus exist without the presence of each other) but can only be actualised in presence of each other (or by other agents/objects within the same range). Thus, an affordance is neither solely subjective, nor objective, at the same point in time. Or both, if you will. (I hope I got at least a chuckle from this rephrasing of Gibson.)
This view is compatible with evolutionary aspects, ecological aspects but is not selectionist [things Chemero makes a good point of what we should want]. In short and simple, there are many, albeit finite, number of affordances and those that have been directly linked to survival and reproduction (which are temporally and situationally dependent, although this specific aspect falls under biology to explore/have explored) have thus determined our phylogenetic development.
I suggest following terminology (although I have to admit that I am slightly confused by all the existing definitions and so reserve myself for the mistake of reifying someone else’s definition. Should this be the case, I apologize and will credit you accordingly)
Actualised: object/agent in a physically coupled, mutual, dynamic relationship that is temporally bound. (Temporally bound refers to that actualizations of affordances do not last forever, in the most extreme case, we die, but, the temporal aspect is necessary, for development, evolution and dynamicism more generally. Although it can be argued that someone else can keep actualizing what I did before death, this is still another instance, another coupling, that can be simultaneous to my coupling. This thus also holds for collective behaviour.)
Realised: object/agent in a perceptually coupled, mutual, dynamic relationship. (Perceptually bound, spatially bound, geographically bound. Referring to the necessary perception of the object and its affordances and (but not necessarily) the agents affordances and the compatibility range of both. Basically, we need direct perception, and perception at all to be able to realise that there are objects at all etc..)
Both these terms are necessarily physically bound, both by their individual physical properties (body of the agent and shape, density etc. of the object) and the physical constraints of the environment (gravity, exemplifying a more so global constraint, and situationally specific things for example social norms, etc.).
This, allows us realisations in absence of the relevant object but actualizations only in presence. It also allows us to avoid Evil Philosopher arguments, examples of cases when we don’t actualise although we can and failing an attempted actualization.
Arriving at the terribly mundane conclusion that we can interact with things when they are there and they are retained when we are not. To be continued… …probably in my master thesis…
Exploding boxes and affordances
If I have understood this correctly, there is an issue with two boxes being identical but only one having a specific affordance -in this case being “pick-up-able” or “touch-able”. Both boxes, to us, are perceived to have the affordance but this is not the case. Therefore, we can’t rely on perception to decide which affordances are available to us.
I am not sure this makes sense. The central point of the masses of words beneath is, does it not assume us to be constant naive explorers of the world? And is this a fair assumption? (Now you don’t have to read all the details, you’re welcome.)
It strikes me however that, the consequence of trying to explore a possible affordance, gives information on which affordances are available to us. Because we are explorers/seekers, we navigate our environment and find out what is, and isn’t. We rely on perception to do so. Is ice walk-on-able? Sometimes. How do we go about finding out? We poke the ice infront of us with a stick, indirectly finding out if the ice is walk-on-able. So we use secondary mechanisms to find out if something has an affordance, if it is not directly perceptible to us, but this relies on that we have seen evidence of it not being able to be relied on by direct perception of our environment. The assumption in the issue may be that we are constant naive explorers, which we aren’t.
Is it not true that both boxes still persist in holding the affordance, only that, in one case we end up exploded and the other we don’t? A big enough box provides the affordance of sitting, regardless of what the consequence of sitting on it is?
It seems to me that this is a classic case of philosophy of mind issues -where we can’t rely on direct perception to perceive what is “actually out there”. For all its worth, if we are to be assumed to be naive explorers, I posit that we will always sit on the exploding chair, touch the exploding box, walk on what is perceived as a solid and rigid surface and so on -because the visual properties, surface and rigidity and so on, lend us to perceive the existence of such an affordance.
So it depends on reliance then. If we rely solely on direct perception (making us constant naive explorers) then objects retain their perceived affordances, regardless of which affordances actually are available to us. If two objects are identical in all perceptible ways, then we can not rely on direct perception to know which affordances are available to us. However. We are not constant naive explorers. We see others interact with objects, get burned on stoves that look like they are turned off. So what do we do? We quickly touch the stove, or look at the knob or hold our hand above the stove.
As for objects, without the involvement of interaction with other things, it is my view that they retain, many, finite number of affordances. These affordances will be available to other objects, but not all affordances to all other objects. Which ones are, will only be realised when another thing, with its own affordances, interact with it, perceive it. With this said, affordances are not the actual relationship between things, it is the fit between one objects affordance and another objects affordance. If they are compatible, then to the specific object, the other object has the specific affordance. They form a relationship, but importantly, both have their affordances retained in the non-presence of each other, if, the affordances are available when interacting with each other.
Example, the structure of DNA contains four characters, only A can bind to B but not C and D and vice versa, in A and Bs absence of each other they both retain the affordance of being able to bind to one other and they both do not have the affordance of binding to C and D. In A and Bs presence of each other they can bind to each other, and thereby realise both of their affordances. In essence, they retain their separate affordances in absence because they can be realised in presence.
No wonder social relationships are so damn important evolutionarily, seeing others being blown up by boxes would surely rule out to me going near any box even similar in visual makeup to the one that exploded!
