JJ Gibson’s theory of affordances has been a mainstay influence in my thinking for many many years (Gibson, 1979). This theory refers to a dynamic, coupled systems approach to behaviour in context with the environment in which the organism is embedded. This is also referred to as an ‘ecological psychology’ approach. Gibson developed ideas based on understanding properties of optic flow in relation to an animal’s movement and the visual information informing motion and perspective from the surrounding scene. This flow of visual information, as he propounded, lends itself to providing stimulus to motivate possibilities for action within the environment. The animal can decide which way to go, what behaviour to select (run, slow, turn, jump) based on this dynamic visual stimulus impinging on the optic nerves.
A later development in the cognitive psychology of vision and action professed dual visual pathways in the brain (Goodale and Milner, 1992, building on Ungerleider and Mishkin, 1982) that accommodate different streams of visual information processing. One (‘ventral’ or occipito-temporal) for discerning ‘what’ an object or stimulus is – qualities that describe object features – and one (‘dorsal’ or occipito-parietal) that discerns relative positioning of the object in space (describing object location and spatial coordinates). Simply speaking, it could be said that the ‘dorsal’ stream subserves the capacity to coordinate motor actions of the organism with respect to the scene and its constituent objects (though of course both pathways have their key functions in visual perception leading to motor behaviour). Loosely tying these strands of theoretical background together, ‘affordance’, as Gibson put it, describes a capacity to act upon the world by virtue of the object and environmental scene features that allow action to be made upon them. So to reiterate, this is a dynamically coupled systematic approach. Or if you like, behavioural action is an emergent property of this coupled system. That is, I, myself as the agent in this environment (my office), have the capacity to act relative to my environment, as a function of this interrelationship with the objects within that environment and the spatial elements of this scene. So it is well within my action potential to rise from my chair (affording sitting currently), navigate across the room from behind my desk, and stroll out (or dash, hop, twirl) into the corridor and seek out the nearest toilet facility. But none of that is intrinsically derived either from myself operating in isolation as an independent and isolated individual being, nor the environment in and of itself (the toilet does not beckon me against my volition – my homeostasis has a key part to play in that). And so to the point with relevance to environments, motivated action, and potential to seek adventure. I wish to use this forum to elaborate upon certain scientific principles and theoretical (and applied) frameworks that inform my perspective on adventure psychology. This includes brain functions, and cognitive psychological models concerning the mechanisms by which we process information from the environment and translate that into actions. This ultimately drives our capacity to perform efficiently and optimally. The concept of affordances, couched in an understanding of how the brain organises the sensory information flooding it at every turn, helps to define which elements of the environment preferentially determine what ‘I’ want to do next. Be that to sit still, close my eyes and try to avoid engaging with the outside world. Or else to use the environment and sensory stimulation to arouse my interests, ignite my enthusiasm, and disrupt my homeostasis to the point I career out into the world (to climb the mountain, dive in the sea, slide down the white slope) in an attempt to restore equilibrium to that system. Dynamic equilibrium in fact. Hereafter, the ‘natural’ state of being may well be to remain active and engaged, and making full use of my vestibular and proprioceptive capacities, balancing on a figurative tight rope straddling two pinnacles. This mode of action could well grant access to an epic vista and an emotional thrill that I would not be able to see from any other vantage in a more sedentary (homeostatic) state. In due course I will elaborate further on different aspects of the scientific influences I incorporate into a grander perspective of ‘CognitvExploration’. References: Gibson, J. J. (1979).
