On this weblog collection, we’ve been discussing consciousness and the way it pertains to varied cognitive capabilities, corresponding to consideration, feelings, and self-regulation. Whereas “consciousness” could be outlined in varied methods theoretically, we’re primarily involved with the subjective expertise of “phenomenal consciousness” in people and different organisms. As an instance this concept, the thinker Thomas Nagel (1974) challenged us to think about “what it’s prefer to be a bat.” However earlier than we will even take into consideration what it’s prefer to be a bat, can we correctly clarify what it’s prefer to be “ourselves”?
Phenomenal consciousness could be described as that fuzzy feeling of the self.

What’s phenomenal consciousness?
This query could be comparatively simple to reply: It’s the wealthy expertise you’re having proper now, comprised of the issues that you simply see, hear, contact, and suppose. It’s, basically, what it seems like to be you. This consists of your private expertise of how the world round you seems, alongside together with your reminiscences and varied inside organic processes (ideas, aches, pains). If we contemplate the Freudian perspective, phenomenology would come with the give attention to how one feels subjectively, or “introspection.”
Whereas your subjective expertise usually is kind of wealthy and full of knowledge, phenomenal consciousness doesn’t “current” all the data that’s processed by your nervous system. As we’ve got argued, the varied information-processing mechanisms, corresponding to consideration, course of a lot info to help a human’s profitable interplay with the setting that solely a subset of this info can enter phenomenal consciousness.
Phenomenal consciousness as a restricted expertise of the world
People are spectacular information-processing methods. The quantity of knowledge that’s detected and processed by our completely different methods is exceptional. Contemplate all of the sensory channels: visible, auditory, contact, scent, style. These methods “subconsciously” course of info continually and usually reliably.
Often, we turn into conscious of solely related or essential info, which suggests we will solely report on a fraction of the data processed that helps our choices and actions. For instance, have you ever ever puzzled when you turned off the oven or locked the door in your method out of your home? These actions have turn into so computerized that they require little or no aware consideration, and thus they’re simply forgotten or ignored. Certainly, if we remembered every part we see or do, we’d in all probability not be as environment friendly as we’re.
Not solely do we’ve got entry to sensory info, however we even have inside info from proprioception (e.g., stability, physique aches) and from self-reflection (e.g., ideas). Planning any motion requires processing and organizing this info, and this happens with completely different ranges of consciousness. Evaluate your expertise of cooking a brand new recipe in a pal’s kitchen to your expertise of constructing tea in your personal home. You’ll in all probability discover that one activity takes rather more effort and aware consciousness than the opposite.
Aware consideration and easy consideration
From all the data processed by our complicated methods, the subset that we phenomenally expertise could be known as aware consideration (i.e., the stuff we will report seeing, listening to, or feeling). What enters aware consideration varies in keeping with context or subjective wants. instance right here is to recall how a lot effort it took if you first realized a brand new ability, like enjoying the piano or enjoying tennis. When first interacting with a piano or tennis racket, the expertise was extra “effortful” as you needed to attend to many various points of the stimuli: the situation of the piano keys and pedals or your grip on the racket and posture. Over time, these processes turn into extra easy, related to a sure experience in utilizing the instruments.
In these examples, the exceptional expertise of the exercise modifications with experience. It started by devoting extra sources to give attention to the instruments and how one can carry out acceptable actions. This developed into requiring much less centered consideration on the duty’s mechanical points however extra on planning, like anticipating a particular sort of backhand that may lead to a profitable shot or specializing in the auditory suggestions that permits you to higher talk emotion by way of your piano-playing reasonably than merely executing an accurate sequence of notes. Phenomenal experiences differ in some ways and are affected by context, previous experiences, and speedy wants.
Hopefully, these examples assist make clear what theorists imply once they say “phenomenal consciousness.” To summarize, it’s the attentive, first-person, vividly wealthy, but extremely restricted, subjective expertise of all of the completely different sorts of knowledge out there to you.
What’s the function of phenomenal consciousness?
Consideration Important Reads
This query is a broadly debated and investigated matter in varied fields of cognitive science, together with psychology, neuroscience, philosophy, and synthetic intelligence. Due to the overlap between consideration and consciousness (theoretically, neurologically, behaviourally), it’s been philosophically troublesome to argue clearly for a singular practical function that consciousness offers. Since consideration processes the data that’s in consciousness, why can we even want phenomenal expertise?
As talked about above (and in earlier posts), we all know the mind processes info and makes choices and coordinates actions outdoors of our consciousness. We don’t must have a wealthy aware expertise of taking steps as we stroll alongside a busy sidewalk whereas adjusting our actions to keep away from different pedestrians or tripping on the curb. Whereas generally we might have richer experiences of strolling, we usually may also navigate by way of our day with out a lot deliberation or effortful consideration due to our experience in doing such issues in typically predictable environments. Some argue that the extra predictable a scenario is, the much less it must be on the forefront of aware expertise (e.g., see Solms & Friston, 2018). Maybe then, consciousness is especially essential for novel and unpredictable conditions.
Phenomenal consciousness additionally tends to contain affective info associated to the visceral nature of being alive. In different phrases, our emotions. That is related to valence judgments assessing if the informational enter is an efficient factor or a nasty factor after which highlighting the acute instances we have to actually attend to (e.g., harmful conditions).
So we will consider phenomenal consciousness as one thing that helps us in additional complicated or unpredictable conditions (e.g., studying new technical expertise, navigating by way of unpredictable environments). It additionally helps us be extra conscious of essential stimuli that can inherently profit survival or different life-maintaining expertise (e.g., see our homeostasis publish).
Whereas these aren’t the definitive or unarguable roles of phenomenal consciousness, they definitely may very well be a part of its perform. The thrilling problem lies within the scientific rationalization of those attainable practical roles and figuring out what info that phenomenal consciousness offers that’s not already being processed successfully and silently by our complicated cognitive and neurological methods.
