Capturing creativity
By: Robert Epstein
Summary: Focuses on how to enhance the creativity of a person. Mysteries of the creative process;
Myths about creativity; Generativity and creativity.
Creativity requires a challenge to start a flow of new ideas, then a way to capture them.
When it comes to creativity, there's good news and very good news. The good news is that the
mysteries of the creative process are finally giving way to a rigorous scientific analysis. The very
good news is that, with the right skills, you can boost your own creative output by a factor of 10
or more. Significant creativity is within everyone's reach--no exceptions. What's more, greater
creativity breeds greater happiness. The creative process is itself a source of joy for most people.
And with new creative powers we're also better able to solve the little problems that beset us
daily.
I make these claims based on nearly 20 years of laboratory research on the creative process,
conducted with animals, with impaired and normal children, and with normal adults (well,
college students). In recent years I've also successfully applied some of the lessons of the
laboratory in real-life settings with children, teachers, and parents, as well as with executives at
some of the nation's largest corporations.
An explosion of creative forces is at hand, and it could make the accomplishments of the
Renaissance look like a ride on a stationary bicycle.
MYTHS AND MYSTICISM
If creativity is so accessible, what's holding back the flood? When I say to a group of a hundred
people, "Please raise your hand if you consider yourself to be creative," why do only 10 hands go
up? Why are corporate leaders, government officials, politicians, crime fighters, teachers, and
parents all starving for new ideas? Why are art, music, and literature in the hands of a tiny
fraction of the population--while the rest of us are mere spectators?
Two answers suggest themselves, and each is disturbing. First, our creative potential is virtually
shut down by early schooling. Teachers are the first to admit this. A kindergarten teacher told me
recently, "I can't believe I get paid to have so much fun every day--before the kids get mined."
Ruined? "Well," he said, "in the first grade the kids have to work all the time. There's no more
time for fun, because there's so much they've got to learn. They're not even allowed to daydream
any more. It's a wonder that any of them ever grow up to be artists or inventors. In kindergarten,
on the other hand, all the kids are artists and inventors."
There's another reason why creativity seems to be in short supply: Myths about creativity are
deeply entrenched in our culture. Myths have enormous power to shape everyday behavior, often
to people's detriment. When people believe the world is flat, for example, they're unlikely to
venture out to sea very far, and "lands away" remain undiscovered.

When it comes to creativity, myths keep most people firmly shorebound. Only artists have
creativity and creativity is rare, we're told. Creativity is mysterious and magical and divine,
people say It's in your right brain, the headlines swear.
None of these beliefs is true, not even slightly The brain hemisphere distinction is based largely
on clinical studies of about 40 "split-brain" patients--people whose brains were severed
surgically in order to treat seizures or other neurological problems. The initial studies of such
patients, conducted in the 1960s, seemed to show significant functional differences between the
left and right cerebral hemispheres. In the 1980s, however, scientists began to reinterpret the
data. The problem is split-brain patients all have abnormal brains to begin with.
As a practical matter, the right-hemisphere myth is nonsense because virtually no one has a split
brain. The two halves of our brain are connected by an immense structure called the corpus
callosum, and the hemispheres also communicate through the sense organs. Creativity has no
precise location in the human brain, and people who promise to reactivate your "neural creativity
zones" are just yanking your chain.
Enough about myths. What about science? In the 1970s, in animal studies I began at Harvard
with behaviorist B. F. Skinner, I became intrigued,--obsessed is more ac-curate--with the fact
that much of the interesting behavior we observed in our subjects had never been trained. We
would provide certain training, and then new, often very complex, behavior would emerge.
Perhaps more important, I eventually realized that the new behavior wasn't random but that it
was related in orderly ways to the behavior that had been trained.
Over the years, my students, colleagues, and I became increasingly adept at providing certain
minimal training that would inexorably lead to the generation of a specific, complex, new
performance--one that could be called "creative." What we ultimately concluded was that
previously established behavior manifests itself in new situations in new yet orderly ways. Novel
behavior is truly new, but the particular novel behavior that emerges in a new situation depends
on the particular behaviors that were established previously--that is, on prior knowledge.
Creativity, in short, is not something mystical; it's an extension of what you already know. To be
more specific, new behaviors (or "ideas") emerge as old behaviors interact, and the process by
which behaviors interact is orderly.
GENERATIVITY & CREATIVITY
Behavior is generative; like the surface of a fast-flowing river, it's inherently and continuously
novel. We never repeat the same action or have the same thought twice, at least not if you look
closely enough. We brush our teeth a slightly different way each morning; we dream new dreams
each night. If you say "dog" twice, a spectrograph will easily distinguish two patterns. Behavior
flows, and it never stops changing.
The language of creativity is imprecise. "Creative" is an everyday term, not a scientific one.
Novel behavior is generated continuously, but it is labeled creative only when it has some special
value to the community. Alas, communities are extremely inconsistent in their use of the

language of creativity. Jackson Pollock would not have been dubbed "creative" in fourteenth-
century Europe; he would have been burned at the stake.
From a scientific perspective, it's not the label "creativity" itself that's of interest--it's the flow of
novel behavior that sometimes inspires the label. How can we account for and understand that
flow? Where does novel behavior come from? How does the "creative process" work?
My research suggests that many forces act simultaneously on the neural determinants of many
different behaviors and that novel behavior is the result of this complex and dynamic process.
Generativity is the basic process that drives all of the behavior we come to label "creative."
In recent years, I've had subjects solving problems directly on a computer touch screen, which
allows us to simulate the performances in real time. Using this technology, we're getting better at
predicting unique, novel performances in individual subjects moment to moment in time, further
suggesting that the creative process is orderly--not mysterious at all.
FOUR TECHNIQUES TO BOOST CREATIVITY
Generativity research suggests four distinct strategies for increasing creative output. Each can be
implemented in different situations in different ways, sometimes in multiple ways.
CAPTURING
New ideas are like rabbits streaking through consciousness; they're fleeting. If you don't grab
them quickly, they're usually gone forever. Just a few minutes ago, while taking care of nature's
business (more about that later), a catchy title for an article about our need for mild stressors--
something like "What Would My Dog Do Without Her Fleas?"--popped into my head. Alas, by
the time I got back to my desk, the tide was gone, and I'm unable to get it back.
The main thing that distinguishes "creative" people from the rest of us is that the creative ones
have learned ways to pay attention to and then to preserve some of the new ideas that occur to
them. They have capturing skills.
The scientist Otto Loewi had struggled for years with a problem in cell biology. One night, a
new approach to the problem occurred to him in his sleep. In the dark, he grabbed a pen and pad,
recorded his new ideas, and went back to sleep. Come morning, he couldn't read his writing! Had
he imagined this great solution, or was it real? The next night he was blessed by the same flash
of insight. This time, he took no chances; he pulled on his clothes and went straight to his lab. He
won the Nobel Prize for the work he began that night.
People who are serious about exploring their creative side develop and practice various methods
of capturing new ideas. Artists carry sketchpads. Writers and advertisers carry notepads or
pocket computers. Inventors make notes on napkins and candy-bar wrappers--especially
inventors of new foods!

Salvador Dali, the great surrealist,used to grab ideas for paintings from the very fertile semi-
sleep state we call the hypnagogic state. He'd lie on a sofa and hold a spoon in one hand,
balancing it on the edge of a glass placed on the floor. Just as he'd drift off to sleep, he'd release
the spoon, and the sound of the spoon hitting the glass would awaken him. Immediately, he'd
sketch the bizarre hypnagogic images he was seeing.
Anyone can do this. We all have bizarre perceptual experiences in those moments before we fall
fully asleep. Dali simply developed a way to seize some of them.
Capturing skills can be taught to young children, to high school kids, to adults, to top executives.
Teachers, parents, and managers can boost the creative output of a group manyfold simply by
providing some simple training and the right materials.
Capturing is easier in certain settings and at certain times, so we improve our catch by
identifying the settings and times that work best for us. For some people, the Three Bs of
Creativity--the Bed, the Bath, and the Bus--are particularly fertile, especially if you keep writing
materials handy in those locations (obviously, today I failed to do so). Others need to sit by a
pool or on a cruise ship or in a lonely cabin in the woods. Years ago I gave a talk on creativity at
the Rowland Institute, a private research center built by Edwin Land, the millionaire inventor of
the Polaroid "Land" camera. Land designed the entire institute to be a giant idea-capturing
machine. Inside, a serene Japanese garden runs the length of the building, with skylights
overhead. He wanted himself and fellow researchers to be able to "hear themselves think" as they
walked, slowly and peacefully, through the magnificent indoor garden--literally, a garden of new
ideas.
CHALLENGING
One way to accelerate the flow of new ideas is by challenging yourself--that is, by putting
yourself in difficult situations in which you're likely to fail to some extent. A challenging
situation is like an "extinction" procedure in the behavioral laboratory. We extinguish behavior
when we withdraw the reinforcers that usually maintain that behavior. In challenging situations,
a great deal of behavior goes unreinforced; it just doesn't work.
When a behavior is unsuccessful, typically it gets weaker. We feel frustrated and upset, and,
most important for creativity, there is a "resurgence" of behaviors that used to be effective. We
begin trying out every other behavior that ever worked for us in the past under similar
conditions. That gets many behaviors competing vigorously, which greatly enhances the
generative process. (Our feelings of frustration and confusion are largely byproducts of this stiff
competition.)
Say you start to turn a door knob that has always turned easily It won't budge. At first, you start
to turn the knob harder; then perhaps you pull up on the knob or push it down. Then maybe you
wiggle it. Eventually, you shove the door with your shoulder or kick it with your foot. What you
do will depend on your history with doors. Eventually, you'll shout for help--maybe even call out
for "mommy," even if your mother is no longer among the living.

It's possible to take advantage of this robust process to spur creativity For example, from time to
time we can give students and employees open-ended problems to solve--problems that have an
infinite number of solutions. Rather than saying, "Please give me three names for our company's
new widget," try saying, "Please give me as many names as possible for the widget." You'll get
two or three times as many proposals from which to make a final selection.
"Ultimate problems"--challenging problems that have no solution--can also be used to accelerate
creative output. With children or friends or colleagues, try spending 15 minutes a week solving
one of these:
o You have 24 hours in which to bring about world peace. How do you do it?
o You have one year in which to clean up all of the pollution on earth and make sure that people
never pollute the planet again. What's your plan?
o Aging is a real drag. Eliminate it.
You shouldn't expect to find a real solution, but you'll certainly stimulate a lot of interesting new
ideas. This is an example of using a "controlled failure system"--a structured challenge that
makes people feel reasonably safe to stimulate new ideas without causing those annoying
myocardial infarctions.
Do we really want to place ourselves in situations in which we know we're going to feel
frustrated and confused? Emphatically, yes! If you're feeling frustrated, you're in the company of
the greatest poets, composers, and inventors of all time, and, more likely than not, you're on the
verge of a new idea. Failure is not something to fear; properly managed, it's a great wellspring of
creativity
BROADENING
Here's a deceptively simple fact: for repertoires of behavior to contribute to the generative
process, they must first exist. In other words, the more training you have and the more diverse
that training is, the greater the potential for creative output. Letting kids float around a classroom
from one "activity center" to another is not the way to go; when we're on our own, we gravitate
toward a very narrow range of learning opportunities. The creative process is spurred on by
multiple well-established repertoires of behavior. Traditional, structured, aggressive methods of
teaching and training have special value in laying a foundation for creativity
A contradiction? Didn't I say that first-grade teachers were monsters who stifled creativity by
doing too much teaching? The problem with traditional education is not that it teaches diverse
subjects or subjects that lack apparent utility; the problem is that it doesn't allocate any time and
training for creativity as such. Kids need to learn things that they don't want to learn--not just to
become good citizens, but also to become more creative people.
If you want to enhance your own creativity, take courses in subjects you know nothing about.
Once a year, at least, take a course at a local college in the last thing you'd ever want to know

about. Land's own breakthrough invention came about because of training he had in
crystallography, chemistry, and other fields. The invention of Velcro, the modern theory of
electron spin, and countless other advances were made possible because their creators had
training in diverse fields.
SURROUNDING
Finally, you can enhance your creativity by surrounding yourself with diverse stimuli--and, even
more important, by changing those stimuli regularly Diverse and changing stimuli promote
creativity because, like resurgence, they get multiple behaviors competing with each other. If you
put a Mickey Mouse hat and pliers on your desk in the morning, your thinking will move in odd
directions during the day Call these items distractions, if you like; they are great reservoirs of
creativity.
Here's the great news: Generativity research shows that everyone has creative abilities. The
generative mechanisms that underlie the creative process operate all the time in each of us. Every
one of us has the creative potential of Mozart or Picasso or Edison or Einstein. To boost your
creative output, capture your new ideas as they occur, challenge yourself in order to get ideas
competing, broaden your training so that many new repertoires of behavior will be available to
compete, and surround yourself as much as possible with diverse and ever-changing stimuli.
Anyone can master these creative strategies. They're all that stand between you and the most
creative people in history.
FUN AND GAMES
Over the years, for various audiences and university classes, I've developed many exercises and
games that both spur creativity and Illustrate how generative processes work. Here are a few of
my favorites:
CAPTURING A DAYDREAM.
You can perform this exercise in a group or on your own--right now, if yon like. Just close your
eyes and let your mind wander freely for a few minutes. You might drift off to the stars; you
might see things you've never seen before. Just let your thoughts wander without deliberately
guiding them. Okay, relax and get started. . . .
Did you leave the room? Did you leave the earth? Did you see or hear or experience anything
that's impossible to experience in reality? Given enough time and an absence of distraction,
everyone answers yes to each of these questions. Behavior is generative--even the covert
perceptual behavior that we call "thought." This simple exercise is especially powerful because it
can quickly convince anyone that everyone has enormous creative potential and that capturing
skills are essential to unlocking that potential.
I've conducted this exercise all over the world, but I've been most deeply moved by its effect on
audiences in Japan. Even bright, professional Japanese people believe that the Japanese are not a

creative lot--this, in spite of the fact that Japanese patents now dominate many categories of
Invention worldwide. But after a few minutes of capturing daydreams, Japanese audiences report
daydreams every bit as bizzare and rich as Salvador Dali's: "I saw you, the teacher, small, in my
hand, and you turned gray and you shrank and disappeared." (What would Freud say about that?
Who cares?) "I flew to the top of the building next door, and I saw this building crumble to the
ground while I ate a sandwich." (IBM was located next door. Was this fellow hoping for a better
Job?)
BUILDING A BETTER CAPTURING MACHINE. Ask a group of people to invent machines
that will help them become better inventors. Specifically, give them five minutes in which to
invent a device that will allow them to capture good ideas on the fly. They can use any materials
at hand, including odd items you may supply, except traditional writing implements (pens,
crayons, paper, computers, etc.).
At a club one evening, I was faced with one of those challenges that every single person dreads.
An appealing woman offered me her telephone number, but I couldn't locate anything with
which to write! I grabbed a napkin, tore off one corner to indicate my starting point, and then
made a pattern of small tears around the edge to capture the number. First seven tears and a
space, then two tears and a space, and then--the rest is none of your business.
THE SHIFTING GAME. Generativity Theory suggests that some of the common methods now
used to promote creativity have limited value, at best. Brainstorming, for example, works to
some extent because it exposes team participants to multiple social stimuli (a "surrounding"
technique). But It also Inhibits creativity by exposing Individuals to disapproval. Participants
may try to withhold signs of disapproval, but eyebrows are still raised, and most people hold
back a wealth of good ideas.
The Shifting Game uses a team optimally to increase creative output. Two teams are selected
from the larger audience. One is instructed to stay together for a 20-minute brainstorming
session. The second team is instructed to "shift" twice from five- minute private work sessions to
five-minute team meetings. Each team must generate names for a new soft drink, and each has a
total of 20 minutes In which to accomplish the task.
The "shifting" group typically generates twice as many Ideas as the brainstorming group. Why?
Because creativity is always an individual process, and social disapproval is the major deterrent
to creativity our entire lives. Groups are far better at selecting good ideas than at generating
them.

... The appearance of creativity at or after FTD onset in individuals with no or little formal artistic training is also well documented (for review see : Chatterjee 2004;Mendez 2004;Miller and Hou 2004;Flaherty 2005Flaherty , 2011Forman et al. 2006;Palmiero et al. 2012;Fletcher et al. 2013;Miller and Miller 2013;de Souza et al. 2014;Miller 2014;Gretton and Ffytche 2014;Acosta 2014;Olney et al. 2017;Cipriani et al. 2019;Geser et al. 2021). However, data on the overall frequency of shift in artistic style or the emergence of creative activities at or after FTD onset are hardly available because capturing creativity fully with usual neuropsychological methods or specifically developed cognitive neuroscience frameworks remains challenging (Griffiths 2008).

The emergence of new artistic activities or shifts in artistic style in patients with frontotemporal dementia (FTD) syndromes is well documented at or after disease onset. However, a closer look in the literature reveals emerging artistic creativity also before FTD onset, although the significance and underlying pathology of such creative endeavors remain elusive. Here, we systematically review relevant studies and report an additional FTD case to elaborate on artistic activities that developed years before disease manifestation by paying particular attention to the sequence of events in individual patients' biography and clinical history. We further discuss the FTD patient's creative activities in the context of their life events, other initial or "premorbid" dementia symptoms or risk factors described in the literature such as mental illness and mild behavioral impairment (MBI), as well as changes in neuronal systems (i.e., neuroimaging and neuropathology). In addition to our FTD patient, we identified five published cases with an FTD syndrome, including three with FTD, one with primary progressive aphasia (PPA), and one with the behavioral variant of PPA (bvPPA). Premorbid novel creativity emerged across different domains (visual, musical, writing), with the FTD diagnosis ensuing artistic productivity by a median of 8 years. Data on late-life and pre-dementia life events were available in four cases. The late creative phase in our case was accompanied by personality changes, accentuation of personality traits, and cessation of painting activities occurred with the onset of memory complaints. Thus, premorbid personality changes in FTD patients can be associated with de novo creative activity. Stressful life events may also contribute to the burgeoning of creativity. Moreover, primary neocortical areas that are largely spared by pathology at early FTD stages may facilitate the engagement in artistic activities, offering a window of opportunity for art therapy and other therapeutic interventions during the MBI stage or even earlier.
... Core engineering science courses that comprise the majority of the undergraduate engineering curriculum include closed-ended problems with one right answer and algorithmic solution paths that do not emphasize or value creative thinking (Felder, 1987). At the same time, it is not yet clear how creativity can be taught or assessed in engineering (Baillie, 2002;Griffiths, 2008). ...

Lay Description What is currently known about the subject matter Creative thinking is an essential skill for engineers to develop innovative products and processes. Creative thinking involves toggling between divergent thinking (coming up with many different original ideas) and convergent thinking (executing an appropriate idea based on engineering analyses). Despite its importance, creative thinking is not often encouraged nor taught in undergraduate engineering curricula, and, similarly, is not well‐researched in that context. The development of creative thinking is supported by students working in Problem‐Based Learning (PBL), in which students work in teams on an open‐ended, “real world” problem. What our paper adds to this We developed an innovative methodology to analyze aspects of divergent thinking in an open‐ended, computer‐based virtual laboratory project. Students engaged in divergent thinking significantly more in the virtual laboratory project as compared to two physical laboratory projects in the same course. The degree of divergent thinking did not correlate to the quality of solution in the virtual laboratory project. The degree of divergent thinking of student teams was about the same as that of experts. The implications of study findings for practitioners Findings support the use of open‐ended, computer‐based virtual laboratory projects to provide students opportunities to practice divergent thinking. The aspects of student teams' divergent thinking in this context is similar to experts. The relationship between divergent thinking and quality of solution is complex. More work needs to be done to understand how to encourage broader creative thinking where student teams toggle between divergent and convergent thinking.

Yaratıcı kişiliğe yönelik yaklaşımlar zamanla farklılaşmıştır. Önceleri yaratıcı kişilik özelliklerinin, herkesin sahip olamayacağı olağanüstü bir yetenek olduğu düşünülmüş ve bu yeteneğe mistik bir anlam yüklenmiştir. Ancak bu düşünce zamanla yerini doğuştan zihinsel becerilere sahip, bir grup insana ait özel bir yetenek olduğu düşüncesine bırakmıştır. Psikoloji çalışmaları sayesinde günümüzde yaratıcı kişilik özellikleri her bireyin doğuştan sahip olduğu, geliştirilebilir bir özellik olarak düşünülmekte ve farklı disiplinlerin üzerinde araştırma yaptığı disiplinler arası bir kavram olarak ele alınmaktadır. Din psikolojisi alanında yaratıcı kişilik üzerine yapılan araştırma sayısı oldukça sınırlı olsa da yapılan araştırmalar dinin yaratıcı düşünmeyi engellediğine ve kolaylaştırdığına yönelik iki farklı sonuç sunmaktadır. Bu araştırmada katılımcıların yaratıcı kişilik özellikleri ve motivasyonel dindarlık düzeylerini ölçmek ve yaratıcı kişilik özellikleri ile motivasyonel dindarlığın birbiri ile olan ilişkisinin çeşitli demografik değişkenler açısından incelemek amaçlanmıştır. Yaratıcı kişilik ile motivasyonel dindarlık olgularını konu edinen bu araştırmada yöntem olarak ilişkisel tarama modeli kullanılmıştır. Araştırmada verilere ulaşmak için anket tekniğinden faydalanılmıştır. Araştırma örneklemini İnönü Üniversitesinde öğrenim görmekte olan birinci, ikinci, üçüncü ve dördüncü sınıf öğrencileri arasından seçkisiz örnekleme yöntemiyle seçilmiş 317 öğrenci oluşturmaktadır. Araştırma sonucuna göre motivasyonel dindarlık ile yaratıcı kişilik özellikleri arasında zayıf düzeyde, pozitif yönlü istatistiksel olarak anlamlı bir ilişki olduğu tespit edilmiştir. Yaratıcı kişilik özellikleri ile yaş arasında zayıf düzeyde, pozitif yönlü istatistiksel olarak anlamlı bir ilişki bulunmaktadır. Yaratıcı kişilik özellikleri düzeyinin cinsiyete göre anlamlı bir farklılık göstermediği tespit edilmiştir. Ancak cinsiyet değişkeni açısından yaratıcı kişilik özellikleri anlamlı farklılık oluşturmasa da erkeklerin yaratıcı kişilik özellikleri düzeyi kadınlardan yüksek çıkmıştır. Yaratıcı kişilik özellikleri anne eğitim durumu bakımından anlamlı bir farklılık göstermemektedir. Ancak yaratıcı kişilik özelliklerine göre en yüksek ortalamalar annesi üniversite mezunu olanlara aittir. Yaratıcı kişilik özellikleri baba eğitim durumu bakımından anlamlı bir farklılık göstermemektedir. Üniversite öğrencilerinin yaratıcı kişilik özelliklerinin aile gelir durumu bakımından anlamlı bir farklılık göstermediği tespit edilmiştir. Yapılan analiz sonucunda yaratıcı kişilik özelliklerinin okul öncesi eğitim alma durumuna göre anlamlı bir farklılık göstermediği tespit edilmiştir. Ancak okul öncesi eğitim almayan bireylerin yaratıcı kişilik özellikleri ortalaması okul öncesi eğitim alanların ortalamasından daha yüksektir.

Creations can be fundamentally intended or unintended from their outset. Past work has focused on intentional creations, finding that people place a premium on effort. We examine the role of unintentionality in the inception of creations in six studies using a variety of stimuli ( N = 1,965), finding that people offer a premium to unintentional creations versus otherwise identical intentional creations. We demonstrate that the unintentionality involved in the inception of a creation results in greater downward counterfactual thought about how the unintentional creation may have never been created at all, and this in turn heightens perceptions that the creation was a product of fate, causing people to place a premium on such creations. We provide evidence for this causal pathway using a combination of mediation and moderation approaches. Further, we illuminate that this premium is not offered when a negative outcome is ascribed to an unintentional creation.

Creativity is one of the most valued human traits: it is the capacity to produce new concepts, ideas, inventions, art. Creativity is perhaps a continuum of everyday creativity to an eminent one. Creativity may be tested by Torrance tests of creative thinking. According to the investment theory, creativity requires i- ntellectual abilities, - knowledge, - ways of thinking, - personality, - motivation, and - environments. There are pedigrees of eminently creative people across various fields. Correlation of psychometric intelligence and creativity is not strong. Creativity is improved by bilingualism. A so-called "creative personality" exists: among its traits belongs - openness, - consciousness, - impulsivity, - autonomy, and - a higher score of Eysencks's psychoticism Many studies of creativity by neuroimaging now exist, but results of surveys and metanalyses are tentative. Some individual studies are more optimistic. There is now some early research aimed at a genetic basis of creativity. The first candidate genes have been identified. Creativity has long been associated with mental disorder. A familial cosegregation of both schizophrenia and bipolar disorder with creativity is suggested. Some psychosocial limits of scientific creativity exist.

Kreativität ist so etwas wie ein Leitwort unserer Zeit geworden, in ihrem Namen werden jetzt Ressourcen aufgewandt, um in der Zukunft Erträge zu realisieren. Dabei ist der Begriff alles andere als klar definiert. Ein Minimalkonsens lässt sich entlang der Wendung, kreativ sei etwas, was Originalität und Wert, Neuheit und Anschlussfähigkeit in sich vereine, finden. Diese Definition lässt jedoch genug Raum dafür, dass sich Entstehungs- und Anwendungskontexte in den Begriff einschreiben können. Das Ergebnis ist ein erhebliches Bedeutungsschillern. Der Text untersucht dieses Schillern, indem er Herkunftskonstellationen nachgeht, den Entwicklungspfad des Begriffes beginnend bei seinen theologischen Anfängen über die Philosophie, die Psychologie, die Soziologie sowie die Hirnforschung und die Pädagogik ausleuchtet. Anschließend werden die begriffsprägenden Handlungsfelder Kunst, Wissenschaft, Wirtschaft und Politik in den Blick genommen. Ziel ist es, Anhaltspunkte dafür zu gewinnen, wie Kreativität in organisationalen wissenschaftlichen Kontexten realisiert werden kann.

Recent research by V. S. Ramachandran and Semir Zeki has used neuroscientific methods to investigate the nature of aesthetic response. By situating their work in the context of post-Kantian aesthetic discourse, this essay demonstrates that such research provides an opportunity to bridge cognitive and artistic approaches to aesthetic experience and offers a provisional theory of art that incorporates both empirical and philosophical traditions. These theories will be considered in relation to Bret Easton Ellis's recent novel Lunar Park (2005), which focuses explicitly on questions of representation and reality. Through a juxtaposition of Ramachandran's emphasis on caricature as a central principle of art and Ellis's focus on distorted and questionable realities, this essay suggests new possibilities for the integration of cognitive science with literary and philosophical criticism.

Iris Murdoch (I.M.) was among the most celebrated British writers of the postwar era. Her final novel, however, received a less than enthusiastic critical response on its publication in 1995. Not long afterwards, I.M. began to show signs of insidious cognitive decline, and received a diagnosis of Alzheimer's disease, which was confirmed histologically after her death in 1999. Anecdotal evidence , as well as the natural history of the condition, would suggest that the changes of Alzheimer's disease were already established in I.M. while she was writing her final work. The end product was unlikely, however, to have been influenced by the compensatory use of dictionaries or thesauri, let alone by later editorial interference. These facts present a unique opportunity to examine the effects of the early stages of Alzheimer's disease on spontaneous written output from an individual with exceptional expertise in this area. Techniques of automated textual analysis were used to obtain detailed comparisons among three of her novels: her first published work, a work written during the prime of her creative life and the final novel. Whilst there were few disparities at the levels of overall structure and syntax, measures of lexical diversity and the lexical characteristics of these three texts varied markedly and in a consistent fashion. This unique set of findings is discussed in the context of the debate as to whether syntax and semantics decline separately or in parallel in patients with Alzheimer's disease.

Behavior is determined by the brain, and the brain varies from person to person. Despite this variability, common neurobiological processes occur. These processes are discussed by Zeki in this essay on one form of variability--artistic expression. By revealing the neural basis of artistic expression, we can discover what processes lie behind other forms of variability, like moral behavior and religious belief.

The problem of finding correspondence between a particular neuronal organization and a specific function of the human brain remains a central question of neuroscience. It is sometimes thought that language and music are two sides of the same intellectual coin, but research on brain-damaged patients has shown that the loss of verbal functions (aphasia) is not necessarily accompanied by a loss of musical abilities (amusia). Amusia without aphasia has also been described. This double dissociation indicates functional autonomy in these mental processes. Yet verbal and musical impairments often occur together. The global picture that emerges from studies of music and its neural substrate is by no means clear and much depends on which subjects and which aspect of musical abilities are investigated. An illustration of these concepts is provided by the case of the French composer Maurice Ravel, who suffered from a progressive cerebral disease of uncertain aetiology, with prominent involvement of the left hemisphere. As a result, Ravel experienced aphasia and apraxia and became unable to compose. The available facts favour a clinical diagnosis of primary progressive aphasia (PPA), with the possibility of an overlap with corticobasal degeneration (CBD). In view of Ravel’s clinical history, we propose that two of his final compositions, the Bolero and the Concerto for the Left Hand, include certain patterns characteristic of right-hemisphere musical abilities and may show the influence of disease on the creative process.

The neural networks associated with processing related pairs of words forming literal, novel, and conventional metaphorical expressions and unrelated pairs of words were studied in a group of 15 normal adults using fMRI. Subjects read the four types of linguistic expressions and decided which relation exists between the two words (metaphoric, literal, or unrelated). According to the Graded Salience Hypothesis (GSH, ), which predicts a selective RH involvement in the processing of novel, nonsalient meanings, it is primarily the degree of meaning salience of a linguistic expression rather than literality or nonliterality, which modulates the degree of left hemisphere (LH) and right hemisphere (RH) processing of metaphors. In the present study, novel metaphorical expressions represented the nonsalient interpretations, whereas conventional metaphors and literal expressions represented the salient interpretations. A direct comparison of the novel metaphors vs. the conventional metaphors revealed significantly stronger activity in right posterior superior temporal sulcus, right inferior frontal gyrus, and left middle frontal gyrus. These results support the GSH and suggest a special role for the RH in processing novel metaphors. Furthermore, the right PSTS may be selectively involved in verbal creativity.

Stress causes impaired performance on tests of creativity. Drugs that block beta-adrenergic receptors improve test performance in patients with test anxiety. Furthermore, catecholamine precursors (L-DOPA) reduce the flexibility of semantic networks. Our study investigated the effect of noradrenergic system modulation on cognitive flexibility in problem solving. Eighteen normal subjects undertook three problem solving tasks (number series, shape manipulation and anagrams) 45 min after propranolol, placebo and ephedrine. On the task that appeared to rely most heavily on cognitive flexibility (anagrams), subjects who were most able to solve these problems demonstrated significantly shorter solution times (logarithmic scores) after propranolol than after ephedrine. This suggested that the noradrenergic system exerts a modulatory effect on cognitive flexibility in problem solving.

Creativity refers to the potential to produce novel ideas that are task-appropriate and high in quality. Creativity in a societal context is best understood in terms of a dialectical relation to intelligence and wisdom. In particular, intelligence forms the thesis of such a dialectic. Intelligence largely is used to advance existing societal agendas. Creativity forms the antithesis of the dialectic, questioning and often opposing societal agendas, as well as proposing new ones. Wisdom forms the synthesis of the dialectic, balancing the old with the new. Wise people recognize the need to balance intelligence with creativity to achieve both stability and change within a societal context.

Parkinson's disease is typically characterised by loss of function and previous abilities, often accompanied by complications of treatment in later stages of the disease. We report on a patient who newly developed an artistic skill after starting treatment for Parkinson's disease. This case offers insight into the neurology of the artistic process as well as into the pathophysiology of psychiatric adverse reactions to the treatment of PD.

This article reviews and develops some theories about the neurobiological basis of creative innovation (CI). CI is defined as the ability to understand and express novel orderly relationships. A high level of general intelligence, domain-specific knowledge and special skills are necessary components of creativity. Specialized knowledge is stored in specific portions of the temporal and parietal lobes. Some anatomic studies suggest that talented people might have alterations of specific regions of the posterior neocortical architecture, but further systematic studies are needed. Intelligence, knowledge and special skills, however, are not sufficient for CI. Developing alternative solutions or divergent thinking has been posited to be a critical element of CI, and clinical as well as functional imaging studies suggest that the frontal lobes are important for these activities. The frontal lobes have strong connections with the polymodal and supramodal regions of the temporal and parietal lobes where concepts and knowledge are stored. These connections might selectively inhibit and activate portions of posterior neocortex and thus be important for developing alternative solutions. Although extensive knowledge and divergent thinking together are critical for creativity they alone are insufficient for allowing a person to find the thread that unites. Finding this thread might require the binding of different forms of knowledge, stored in separate cortical modules that have not been previously associated. Thus, CI might require the co-activation and communication between regions of the brain that ordinarily are not strongly connected. The observations that CI often occurs during levels of low arousal and that many people with depression are creative suggests that alterations of neurotransmitters such as norepinephrine might be important in CI. High levels of norepinephrine, produced by high rates of locus coeruleus firing, restrict the breadth of concept representations and increase the signal to noise ratio, but low levels of norepinephrine shift the brain toward intrinsic neuronal activation with an increase in the size of distributed concept representations and co-activation across modular networks. In addition to being important in divergent thinking, the frontal lobes are also the primary cortical region that controls the locus coeruleus-norepinephrine system. Thus creative people may be endowed with brains that are capable of storing extensive specialized knowledge in their temporoparietal cortex, be capable of frontal mediated divergent thinking and have a special ability to modulate the frontal lobe-locus coeruleus (norepinephrine) system, such that during creative innovation cerebral levels of norepinephrine diminish, leading to the discovery of novel orderly relationships.

It has been conjectured that the cognitive basis of intelligence is the ability to make fluid or creative analogical relationships between distantly related concepts or pieces of information (Hofstadter, D.R. 1995. Fluid Concepts and Creative Analogies. Basic Books, New York., Hofstadter, D.R. 2001. Analogy as the Core of Cognition. In The Analogical Mind: Perspectives from Cognitive Science (D. Gentner, K. J. Holyoak and B. N. Kokinov, Ed.). pp. 504-537. MIT Press, Cambridge, Mass.). We hypothesised that fluid analogy-making tasks would activate specific regions of frontal cortex that were common to those of previous inferential reasoning tasks. We report here a novel self-paced event-related fMRI study employed to investigate the neural correlates of intelligence associated with undertaking fluid letter string analogy tasks. Stimuli were adapted from items of the AI program Copycat (Mitchell, M. 1993. Analogy-making as Perception: A computer model. The MIT Press, Cambridge MA.). Twelve right-handed adults chose their own "best" completions from four plausible response choices to 55 fluid letter string analogies across a range of analogical depths. An analysis using covariates determined per subject by analogical depth revealed significant bilateral neural activations in the superior, inferior, and middle frontal gyri and in the anterior cingulate/paracingulate cortex. These frontal areas have been previously associated with reasoning tasks involving inductive syllogisms, syntactic hierarchies, and linguistic creativity. A higher-order analysis covarying participants' verbal intelligence measures found correlations with individual BOLD activation strengths in two ROIs within BA 9 and BA 45/46. This is a provocative result given that verbal intelligence is conceptualised as being a measure of crystallised intelligence, while analogy making is conceptualised as requiring fluid intelligence. The results therefore support the conjecture that fluid analogising could underpin general intellectual performance.

Creativity is important for social survival and individual wellbeing; science, art, philosophy and technology have been enriched and expanded by this trait. To our knowledge this is the first study probing differences in brain cerebral blood flow (CBF) between highly creative individuals (scientists and/or artists socially recognized for their contributions to their fields with creativity indexes corresponding to the 99% percentile) and average control subjects while performing a verbal task from the Torrance Tests of Creative Thinking. Additionally, we correlated CBF with creativity dimensions such as fluency, originality and flexibility. Subjects with a high creative performance showed greater CBF activity in right precentral gyrus, right culmen, left and right middle frontal gyrus, right frontal rectal gyrus, left frontal orbital gyrus, and left inferior gyrus (BA 6, 10, 11, 47, 20), and cerebellum; confirming bilateral cerebral contribution. These structures have been involved in cognition, emotion, working memory, and novelty response. The score on the three creativity dimensions--fluency, originality, and flexibility--correlated with CBF activation in right middle frontal gyrus and right rectal gyrus (Brodmann Area 6, 11). Moreover, fluency and flexibility strongly correlated with CBF in left inferior frontal gyrus and originality correlated with CBF in left superior temporal gyrus and cerebellar tonsil. These findings suggest an integration of perceptual, volitional, cognitive and emotional processes in creativity. The higher CBF found in particular brain regions of highly creative individuals during the performance of a creative task provides evidence of a specific neural network related to the creative process.
