Cognitive Science Quotes

The purpose of education should ultimately be the advancement of the species. And for this to actually happen, the world needs the kind of education by means of which character is formed, strength of the mind is increased and the human intellect is expanded beyond its own limits.

~ Abhijit Naskar

Certain things need to be done again and again in life, but those things can be learned only in context, not as an abstraction. Different contexts must be provided in order to motivate students and to provide real world skills that will be remembered, not because they were studied and tested but because they were practicied again and again.

~ Roger Schank

There are endless books about what every third grader must know that use the idea that factual knowledge is the basis of the ability to read as their justification. Unfortunately, the writers of these tracts have misunderstood the cognitive science behind those statements. It is difficult to read things when you don't understand what they are about, but it does not follow from that thatthe solution is to ram that knowledge down kids' throats and then have them read. It is much more clever to have them read about what they know and to gradually increase their knowledge through stories that cause them to have to learn more in order to make the stories understandable to them.

~ Roger Schank

I'm not suggesting that teachers never tell the truth, only that it isn't necessary to do it all the time. Since coming to one's own conclusions is mostly how we learn, the real job of a teacher is to force students to come to sensible conclusions by confronting what they already believe with stuff that is antithetical to those beliefs. A confused person has only 2 choices. Admit he is confused and doesn't care, or resolve the confusion. Resolving the confusion invloves thinking. Teachers can encourage thinking by making sure students have something confusing to think about.

~ Roger Schank

In summary, a good teacher does the following:- never tells a student anything that the teacher thinks is true- never allows himself to be the ultimate judge of his own students' success- teacher practice first, theory second (if he must teach theory at all)- does not come up with lists of knowledge that every student must know- doesn't teach anything unless he can easily explain the use of learning it- assigns no homework, unless that homework is to produce something- groups students according to their interests and abilities, not their ages- ensures that any reward to a student is intrinsic- teaches students things they may actually need to know after they leave school- helps students come up with their own explanations when they have made a mistake- never assumes that a student is listening to what he is saying- never assumes that students will do what he asks them to do if what he asked does not relate to a goal they truly hold- never allows pleasing the teacher to be the goal of the student- understands that students won't do what he tells them if they don't understand what is being asked of them- earns the respect of students by demonstrating abilities- motivate students to do better, and does not help them to do better- understands that his job is to get students to do something- understands that experience, not teachers, changes belief systems- confuses students- does not expect credit for good teaching

~ Roger Schank

Indoctrination is not just demeaning to the human conscience, it is lethal for the flourishing psychology of the hungry, young mind.

~ Abhijit Naskar

All men either consciously or subconsciously crave for authority over their environment, especially over their peers in the society, male and female alike. Women on the other hand, crave for intimacy especially from their female peers in the society. Colloquially this is what you call “gossiping”.

~ Abhijit Naskar

The female brain is engineered to avoid conflicts at all cost, whereas the male brain pleasures conflicts in the purpose of being the boss.

~ Abhijit Naskar

Physiology and Psychology are not at all separate from each other. Rather they are deeply intertwined.

~ Abhijit Naskar

[O]ur percept is an elaborate computer model in the brain, constructed on the basis of information coming from [the environment], but transformed in the head into a form in which that information can be used. Wavelength differences in the light out there become coded as 'colour' differences in the computer model in the head. Shape and other attributes are encoded in the same kind of way, encoded into a form that is convenient to handle. The sensation of seeing is, for us, very different from the sensation of hearing, but this cannot be directly due to the physical differences between light and sound. Both light and sound are, after all, translated by the respective sense organs into the same kind of nerve impulses. It is impossible to tell, from the physical attributes of a nerve impulse, whether it is conveying information about light, about sound or about smell. The reason the sensation of seeing is so different from the sensation of hearing and the sensation of smelling is that the brain finds it convenient to use different kinds of internal model of the visual world, the world of sound and the world of smell. It is because we internally use our visual information and our sound information in different ways and for different purposes that the sensations of seeing and hearing are so different. It is not directly because of the physical differences between light and sound.

~ Richard Dawkins

[T]he form that an animal's subjective experience takes will be a property of the internal computer model. That model will be designed, in evolution, for its suitability for useful internal representation, irrespective of the physical stimuli that come to it from outside. Bats and we need the same kind of internal model for representing the position of objects in three-dimensional space. The fact that bats construct their internal model with the aid of echoes, while we construct ours with the aid of light, is irrelevant.

~ Richard Dawkins

Computation has finally demystified mentalistic terms. Beliefs are inscriptions in memory, desires are goal inscriptions, thinking is computation, perceptions are inscriptions triggered by sensors, trying is executing operations triggered by a goal.

~ Steven Pinker

Each of your brains creates its own myth about the universe.

~ Abhijit Naskar

The causal, abstract, binary, holistic, and reductionist functions of the human brain all help you to process the enormous amount of information coming into our brain from the external world every day.

~ Abhijit Naskar

In every walk of life, you do have the freedom to choose, but that freedom is based on the perception of the world and yourself which you have gained until that moment of life.

~ Abhijit Naskar

Truly to realize the ambitions of a science of mind does not solely involve learning about such issues as how we know, perceive and solve problems; it involves finding out tow hat extent the world outside us is knowable by us, and indeed prescribing the limits of inquiry for disciplines like Physics which claim to afford knowledge of the external physical world.

~ Sean O Nuallain

Even though the world hails Joan of Arc as some sort of hero, which she undoubtedly was, what pains me the most is that her pathological condition ultimately led to her demise at the age of only nineteen.

~ Abhijit Naskar

Pathology can indeed cause experiences of the Kingdom of God, but not all God experiences are caused by pathology.

~ Abhijit Naskar

Mindless action without a real understanding of the ramifications is only likely to result in serious miscalculations or a colossal waste of time. Avoid both by using your judgment, filtered through both knowledge and experience. Use common sense and logic as a counterbalance to emotion.

~ David Amerland

A synthesis—an abstraction, chunk, or gist idea—is a neural pattern. Good chunks form neural patterns that resonate, not only within the subject we’re working in, but with other subjects and areas of our lives. The abstraction helps you transfer ideas from one area to another. That’s why great art, poetry, music, and literature can be so compelling. When we grasp the chunk, it takes on a new life in our own minds—we form ideas that enhance and enlighten the neural patterns we already possess, allowing us to more readily see and develop other related patterns. Once we have created a chunk as a neural pattern, we can more easily pass that chunked pattern to others, as Cajal and other great artists, poets, scientists, and writers have done for millennia, Once other people grasp that chunk, not only can they use it, but also they can more easily create similar chunks that apply to other areas in their lives—an important part of the creative process.

~ Barbara Oakley

If you are one of those people who can’t hold a lot in mind at once—you lose focus and start daydreaming in lectures, and have to get to someplace quiet to focus so you can use your working memory to its maximum—well, welcome to the clan of the creative. Having a somewhat smaller working memory means you can more easily generalize your learning into new, more creative combinations. Because your learning new, more creative combinations. Having a somewhat smaller working memory, which grows from the focusing abilities of the prefrontal cortex, doesn’t lock everything up so tightly, you can more easily get input from other parts of your brain. These other areas, which include the sensory cortex, not only are more in tune with what’s going on in the environment, but also are the source of dreams, not to mention creative ideas. You may have to work harder sometimes (or even much of the time) to understand what’s going on, but once you’ve got something chunked, you can take that chunk and turn it outside in and inside round—putting it through creative paces even you didn’t think you were capable of! Here’s another point to put into your mental chunker: Chess, that bastion of intellectuals, has some elite players with roughly average IQs. These seemingly middling intellects are able to do better than some more intelligent players because they practice more. That’s the key idea. Every chess player, whether average or elite, grows talent by practicing. It is the practice—particularly deliberate practice on the toughest aspects of the material—that can help lift average brains into the realm of those with more “natural” gifts. Just as you can practice lifting weights and get bigger muscles over time, you can also practice certain mental patterns that deepen and enlarge in your mind.

~ Barbara Oakley

Memory results from a process of continual re-categorization which, by its nature, must be procedural and involve continual motor activity and repeated rehearsal.

~ Gerald Edelman

Humanity has pondered over the meaning of God since its beginning. It is one of those cognitive features that came along with the advent of modern Human Consciousness.

~ Abhijit Naskar

Once we have isolated the computational and neurological correlates of access-consciousness, there is nothing left to explain. It's just irrational to insist that sentience remains unexplained after all the manifestations of sentience have been accounted for, just because the computations don't have anything sentient in them. It's like insisting that wetness remains unexplained even after all the manifestations of wetness have been accounted for, because moving molecules aren't wet.

~ Steven Pinker

Consciousness may be seen as the haughty and restless second cousin of morphology. Memory is its mistress, perception its somewhat abused wife, logic its housekeeper, and language its poorly paid secretary

~ Gerald Edelman

When finally substantiated by scientific means, such a view will allow an individual to see his place in the world with greater clarity-- how he came from the world and how he may contribute to his fellows while he enjoys for a brief time the privilege of consciousness and communication.

~ Gerald Edelman

Sound waves, regardless of their frequency or intensity, can only be detected by the Mole Fly’s acute sense of smell—it is a little known fact that the Mole Fly’s auditory receptors do not, in fact, have a corresponding center in the brain designated for the purposes of processing sensory stimuli and so, these stimuli, instead of being siphoned out as noise, bypass the filters to be translated, oddly enough, by the part of the brain that processes smell. Consequently, the Mole Fly’s brain, in its inevitable confusion, understands sound as an aroma, rendering the boundary line between the auditory and olfactory sense indistinguishable.Sounds, thus, come in a variety of scents with an intensity proportional to its frequency. Sounds of shorter wavelength, for example, are particularly pungent. What results is a species of creature that cannot conceptualize the possibility that sound and smell are separate entities, despite its ability to discriminate between the exactitudes of pitch, timbre, tone, scent, and flavor to an alarming degree of precision. Yet, despite this ability to hyper-analyze, they lack the cognitive skill to laterally link successions of either sound or smell into a meaningful context, resulting in the equivalent of a data overflow.And this may be the most defining element of the Mole Fly’s behavior: a blatant disregard for the context of perception, in favor of analyzing those remote and diminutive properties that distinguish one element from another. While sensory continuity seems logical to their visual perception, as things are subject to change from moment-to-moment, such is not the case with their olfactory sense, as delays in sensing new smells are granted a degree of normality by the brain. Thus, the Mole Fly’s olfactory-auditory complex seems to be deprived of the sensory continuity otherwise afforded in the auditory senses of other species. And so, instead of sensing aromas and sounds continuously over a period of time—for example, instead of sensing them 24-30 times per second, as would be the case with their visual perception—they tend to process changes in sound and smell much more slowly, thereby preventing them from effectively plotting the variations thereof into an array or any kind of meaningful framework that would allow the information provided by their olfactory and auditory stimuli to be lasting in their usefulness.The Mole flies, themselves, being the structurally-obsessed and compulsive creatures that they are, in all their habitual collecting, organizing, and re-organizing of found objects into mammoth installations of optimal functional value, are remarkably easy to control, especially as they are given to a rather false and arbitrary sense of hierarchy, ascribing positions—that are otherwise trivial, yet necessarily mundane if only to obscure their true purpose—with an unfathomable amount of honor, to the logical extreme that the few chosen to serve in their most esteemed ranks are imbued with a kind of obligatory arrogance that begins in the pupal stages and extends indefinitely, as they are further nurtured well into adulthood by a society that infuses its heroes of middle management with an immeasurable sense of importance—a kind of celebrity status recognized by the masses as a living embodiment of their ideals. And yet, despite this culture of celebrity worship and vicarious living, all whims and impulses fall subservient, dropping humbly to the knees—yes, Mole Flies do, in fact, have knees!—before the grace of the merciful Queen, who is, in actuality, just a puppet dictator installed by the Melic papacy, using an old recycled Damsel fly-fishing lure. The dummy is crude, but convincing, as the Mole flies treat it as they would their true-born queen.

~ Ashim Shanker

It is not about whether you have free will, rather it is about whether you have enough experience to make the best possible wilful decision in the current moment of life.

~ Abhijit Naskar

To deny the truth of our own experience in the scientific study of ourselves is not only unsatisfactory; it is to render the scientific study of ourselves without a subject matter. But to suppose that science cannot contribute to an understanding of our experience may be to abandon, within the modern context, the task of self-understanding. Experience and scientific understanding are like two legs without which we cannot walk. We can phrase this very same idea in positive terms: it is only by having a sense of common ground between cognitive science and human experience that our understanding of cognition can be more complete and reach a satisfying level. We thus propose a constructive task: to enlarge the horizon of cognitive science to include the broader panorama of human, lived experience in a disciplined, transformative analysis.

~ Evan Thompson

If we are to know ourselves, philosophy needs to maintain an ongoing dialogue with the sciences of mind.

~ George Lakoff

The hormonal interplay inside a woman’s head creates her reality. Her hormones tell her day to day what’s important. They mold her desires and values.

~ Abhijit Naskar

Tis from the resemblance of the external actions of animals to those we ourselves perform, that we judge their internal likewise to resemble ours; and the same principle of reasoning, carry'd one step further, will make us conclude that since our internal actions resemble each other, the causes, from which they are deriv'd, must also be resembling. When any hypothesis, therefore, is advanc'd to explain a mental operation, which is common to men and beasts, we must apply the same hypothesis to both.

~ David Hume

Cognitive science has something of enormous importance to contribute to human freedom: the ability to learn what our unconscious conceptual systems are like and how our cognitive unconscious functions. If we do not realize that most of our thought is unconscious and that we think metaphorically, we will indeed be slaves to the cognitive unconscious. Paradoxically, the assumption that we have a radically autonomous rationality as traditionally conceived actually limits our rational autonomy. It condemns us to cognitive slavery - to an unaware and uncritical dependence on our unconscious metaphors. To maximize what conceptual freedom we can have, we must be able to see through and move beyond philosophies that deny the existence of an embodied cognitive unconscious that governs most of our mental lives.

~ George Lakoff

Perceptions of the world and of other actors diverge from reality in patterns that we can detect and for reasons that we can understand.

~ Robert Jervis

Sexual thoughts float through a man’s brain many times a day, while on the contrary a woman has them only one to four times a day.

~ Abhijit Naskar

A choice architect has the responsibility for organizing the context in which people make decisions. [T]here are many parallels between choice architecture and more traditional forms of architecture. A crucial parallel is that there is no such thing as a “neutral” design. [A]s good architects know, seemingly arbitrary decisions, such as where to locate the bathrooms, will have subtle influences on how the people who use the building interact. [S]mall and apparently insignificant details can have major impacts on people’s behavior. [I]n many cases, the power of these small details comes from focusing the attention of users in a particular direction. Good architects realize that although they can’t build the perfect building, they can make some design choices that will have beneficial effects. And just as a building architect must eventually build some particular building, a choice architect must [for example] choose a particular arrangement of food options at lunch, and by so doing she can influence what people eat. She can nudge.

~ Richard H. Thaler

The brain works in a holistic, cooperative way that makes our basest desire or most abject fear as expressive of who we are as abstract thinking of the highest order. That means that we are all equal part snakes, monkeys, and spacemen.

~ David Amerland

The mechanism by which spirituality becomes passionate is metaphor. An ineffable God requires metaphor not only to be imagined but to be approached, exhorted, evaded, confronted, struggled with, and loved. Through metaphor, the vividness, intensity, and meaningfulness of ordinary experiences becomes the basis of a passionate spirituality. An ineffable God becomes vital through metaphor: The Supreme Being. The Prime Mover. The Creator. The Almighty. The Father. The King of Kings. Shepherd. Potter. Lawgiver. Judge. Mother. Lover. Breath. The vehicle by which we are moved in passionate spirituality is metaphor. The mechanism of such metaphor is bodily. It is a neural mechanism that recruits our abilities to perceive, to move, to feel, and to envision in the service not only of theoretical and philosophical thought, but of spiritual experience.

~ George Lakoff

Children discover and verify their theories in quite the same way that scientists do: through experimentation. They manipulate the world and discover regularities of causation from those manipulations. Why do they do it? The discovery of regularities comes with a pleasurable burst of insight, which all of us, but especially children and scientists, continuously long for like bonbons or opium.

~ Matthew M. Hurley

...[T]he whole undertaking of philosophical inquiry requires a prior understanding of the conceptual system in which the undertaking is set. That is an empirical job for cognitive science and cognitive semantics. ... Unless this job is done, we will not know whether the answers philosophers give to their questions are a function of the conceptualization built into the questions themselves.

~ George Lakoff
