A Cognição Aumentada do Flash

Como minha pesquisa no TIDD é sobre Histórias em Quadrinhos isso faz com que eu acompanhe de bastante perto o que se diz/produz sobre essa arte (além, óbvio, de eu ser um grande fã, como este blog é testemunha).

Nessas navegações pela web, me deparei com um post interessante sobre o termo "Cognição Ampliada" (Augmented Cognition) relacionado ao personagem Flash. Vocês devem conhecer: é aquele cara de roupa vermelha que corre muito rápido. Vamos aos fatos:

Na revista "The Flash #2", de outubro deste ano, sugerem ao personagem que use sua supervelocidade em seu próprio cérebro, para que alterasse sua percepção em relação ao ambiente ao seu redor e à forma de processar informações.

Isso foi representado visualmente da seguinte forma:

Como fãs são pessoas obstinadas e a ficção quase sempre gera uma busca por mais conhecimento, o pessoal do site Speed foi buscar respaldo na ciência para explicar a história apresentada no gibi e para isso entrevistaram o  Dr. Peter A. Hancock, Professor e pesquisador da University of Central Florida e membro da Augmented Cognition International Society (que eu nem imaginava que existia). Reproduzo abaixo a conversa com o Professor Hancock. Achei muito interessante e resolvi compartilhar aqui. 

Hancock tem alguns artigos que parecem bem interessantes (pelos menos os títulos, ainda não li). Os links estão ao final do texto.

We reached out to Dr. Peter A. Hancock, Provost’s Distinguished Research Professor at The University of Central Florida and member of theAugmented Cognition International Society, to get his take on the AugCog concepts as presented in Flash.  His responses provided a detailed look into an exciting area of neuroscience.  Read on, after the jump…
Q:  Flash #2 describes Augmented Cognition as “a neuroscience focused on expanding the limits of human brain cognition.”  A character in the book suggests that Flash can access the source of his super-speed powers, the “Speed Force,” in order to “…eliminate the natural bottlenecking of information that occurs due to the limits of human physiology.”  How accurate do you feel this description is?
DR. P. A. HANCOCK:  This is actually quite a reasonable suggestion.  The question is: why are there bottlenecks in the first place and what evolutionary cause do they serve.  There is some highly intriguing work which passes visual images very quickly (just a few milliseconds) past a human observer and then their brainwave recordings are used to help a computer to sort which images have likely targets.  Thus, the brain here filters at a tremendously high rate (better than many computerized search algorithms), and the output can then be surveyed more slowly as the actual targets are determined consciously on-screen.  How is it the brain is able to work this quickly and yet consciousness struggles to keep up?  I think this is one of the conundra that augmented cognition is looking to investigate and potentially ‘solve.’  Although whether we will like the solution is also the matter of much discussion.

Q:  As a board member on the Augmented Cognition International Society, can you tell us about your role, and some of the implications and possibilities of Augmented Cognition?
PH:  In the past, my main function has been associated with Conferences and serving as a referee on submitted papers, and of course attending a number of these Conferences alongside my students and colleagues.  One of the issues that has always intrigued me is why people are so slow at learning [note: see 'Can Technology Cure Stupidity?'].  It has been suggested that the natural ‘design lifetime’ of a human being is about 23 years of age (about the time we get out of College!).  While I like the idea of lifetime learning, why are the methods we have of information transmission to humans (learning), so slow?  It echoes the element in the ‘Matrix’ where individuals are able to assimilate expert skills in seconds.  Radical changes in our timescale of learning would have profound implications for all of human life – it is one issue AC can address and help with.

Q:  Flash uses his new-found abilities to sort through possible outcomes at super-speed and make split-second decisions with complete certainty.  Some of the areas addressed on the Society’s website include “…limitations in attention, memory, learning, comprehension, visualization abilities, and decision making.”  In your option, how could someone operating at super-speed use access to Augmented Cognition to achieve a nearly “precognitive” state?
PH:  Humans have already evolved to use such abilities.  You don’t need to react at ‘super-speed’ if you can anticipate.  This is, in part, what the prefrontal cortex is for – ‘getting out ahead of time.’ [see ‘Battle for Time in the Brain’].  Most of our memory is now being ported to the external technology (e.g., web sources etc).  Soon, we will have a growth of equivalent ‘apps’ for certain forms of decision-making (they will come in as advisories, e.g., ‘what should I eat and where today?), the big issue will be attention.  We still don’t know enough about attention and the current theories need to be revised.  Part of the answer may be biochemical as much as neurocognitive solutions.  Neuroscience promises much but progress is actually slow because this is a such a difficult problem.  ‘Super-speed’ is also relative.  Once everyone works at that rate it will just be the new ‘normal.’  ‘Pre-cognitive’ will simply mean knowing much more concerning the world about you.  You can argue people show vast individual differences in this form of ‘awareness’ now.
Q:  Does a concept such as “AugCog” redefine  “decision,” and if so, how?
PH:  I don’t know what AC ‘defines’ decisions as but in my mind they are inflexion points in space-time and for humans they are irregularities in their personal (Minkowski) space-time line.  One can define a decision to be at a trivial level (e.g., to breath in is potentially a ‘decision’) but I think AC focuses on the ‘cognitive’ level.  Even here we talk of ‘skills’ ‘rules’ and ‘knowledge’ to parse decision levels.  Also, there are merging ‘camps’ of decision making combining the ‘heuristics and biases’ approaches with the ‘recognition-primed decision making’ (RPD) approaches.  It’s an exciting time in this particular field.

Are you a fan of comic books, or science fiction?  Augmented Cognition seems right at home in a Flash comic book, but is also grounded in 21st Century reality.  In the 1950s, when this version of the Flash first appeared, much of the science on display was more “psuedo” than science.  How does it feel to be operating on the very edge of current technology and science, and literally keeping pace with science fiction?
PH:  I’m a great fan of Comic Books (I collect early ‘Lois Lane’ and love the old cover art) [see ‘Can you trust your Robot?’].  Science fiction (at least the good stuff) has always been explorations of potential hypotheses (what if scenarios) often projected far out, but always having to link with the present in some way.  Good science fiction also poses moral questions that we can face in ‘fantasy worlds’ knowing that eventually we might have to face their analog in the real world (e.g., can a computer think and what happens when it does?).  Like the frontal cortex of an individual, science fiction may be part of the ‘frontal cortex’ of society (asking an probing about possible futures).  I would like to believe I do interesting things but keeping up with even some parts of certain areas of neuroscience is taxing today.  Hopefully, we can encourage a bunch of youngsters to get interested in such areas by their reading of them in ‘Flash.’

Now that AugCog will be playing a prominent role, will you be picking upFlash next month?
PH:  If you can find a place in the next story for a short, fat, ugly, ex-English (now American) scientist who can help Flash with some crucial Aug Cog problem – I’m there.
