Intelligence
Intelligence has been defined in different ways, including the abilities for abstract thought, understanding, communication, reasoning, learning, planning, emotional intelligence and problem solving.
Intelligence is most widely studied in humans, but has also been observed in animals and plants. Artificial intelligence is the intelligence of machines or the simulation of intelligence in machines.
Numerous definitions of and hypotheses about intelligence have been proposed since before the twentieth century, with no consensus reached by scholars. Within the discipline of psychology, various approaches to human intelligence have been adopted. The psychometric approach is especially familiar to the general public, as well as being the most researched and by far the most widely used in practical settings.[1]

[edit] History of the term
Intelligence derives from the Latin verb intelligere which derives from inter-legere meaning to "pick out" or discern. A form of this verb, intellectus, became the medieval technical term for understanding, and a translation for the Greek philosophical term nous. This term was however strongly linked to the metaphysical and cosmological theories of teleological scholasticism, including theories of the immortality of the soul, and the concept of the Active Intellect (also known as the Active Intelligence). This entire approach to the study of nature was strongly rejected by the early modern philosophers such as Francis Bacon, Thomas Hobbes, John Locke, and David Hume, all of whom preferred the word "understanding" in their English philosophical works.[2][3] Hobbes for example, in his Latin De Corpore, used "intellectus intelligit" (translated in the English version as "the understanding understandeth") as a typical example of a logical absurdity.[4] The term "intelligence" has therefore become less common in English language philosophy, but it has later been taken up (without the scholastic theories which it once implied) in more contemporary psychology.
[edit] Definitions
How to define intelligence is controversial. Groups of scientists have stated the following:
- from "Mainstream Science on Intelligence" (1994), an editorial statement by fifty-two researchers:
A very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly and learn from experience. It is not merely book learning, a narrow academic skill, or test-taking smarts. Rather, it reflects a broader and deeper capability for comprehending our surroundings—"catching on," "making sense" of things, or "figuring out" what to do.[5]
- from "Intelligence: Knowns and Unknowns" (1995), a report published by the Board of Scientific Affairs of the American Psychological Association:
Individuals differ from one another in their ability to understand complex ideas, to adapt effectively to the environment, to learn from experience, to engage in various forms of reasoning, to overcome obstacles by taking thought. Although these individual differences can be substantial, they are never entirely consistent: a given person's intellectual performance will vary on different occasions, in different domains, as judged by different criteria. Concepts of "intelligence" are attempts to clarify and organize this complex set of phenomena. Although considerable clarity has been achieved in some areas, no such conceptualization has yet answered all the important questions, and none commands universal assent. Indeed, when two dozen prominent theorists were recently asked to define intelligence, they gave two dozen, somewhat different, definitions.[6][7]
Besides the foregoing definitions, these psychology and learning researchers also have defined intelligence as:
| Researcher | Quotation |
|---|---|
| Alfred Binet | Judgment, otherwise called "good sense," "practical sense," "initiative," the faculty of adapting one's self to circumstances ... auto-critique.[8] |
| David Wechsler | The aggregate or global capacity of the individual to act purposefully, to think rationally, and to deal effectively with his environment.[9] |
| Lloyd Humphreys | "...the resultant of the process of acquiring, storing in memory, retrieving, combining, comparing, and using in new contexts information and conceptual skills."[10] |
| Cyril Burt | Innate general cognitive ability[11] |
| Howard Gardner | To my mind, a human intellectual competence must entail a set of skills of problem solving — enabling the individual to resolve genuine problems or difficulties that he or she encounters and, when appropriate, to create an effective product — and must also entail the potential for finding or creating problems — and thereby laying the groundwork for the acquisition of new knowledge.[12] |
| Linda Gottfredson | The ability to deal with cognitive complexity.[13] |
| Sternberg & Salter | Goal-directed adaptive behavior.[14] |
| Reuven Feuerstein | The theory of Structural Cognitive Modifiability describes intelligence as "the unique propensity of human beings to change or modify the structure of their cognitive functioning to adapt to the changing demands of a life situation."[15] |
What is considered intelligent varies with culture. For example, when asked to sort, the Kpelle people take a functional approach. A Kpelle participant stated "the knife goes with the orange because it cuts it." When asked how a fool would sort, they sorted linguistically, putting the knife with other implements and the orange with other foods, which is the style considered intelligent in other cultures.[16]
[edit] Human intelligence
[edit] Psychometrics
The approach to understanding intelligence with the most supporters and published research over the longest period of time is based on psychometric testing. It is also by far the most widely used in practical settings. Intelligence quotient (IQ) tests include the Stanford-Binet, Raven's Progressive Matrices, the Wechsler Adult Intelligence Scale and the Kaufman Assessment Battery for Children. There are also psychometric tests that are not intended to measure intelligence itself but some closely related construct such as scholastic aptitude. In the United States examples include the SSAT, the SAT, the ACT, the GRE, the MCAT, the LSAT, and the GMAT.[1]
Intelligence tests are widely used in educational, business, and military settings due to their efficacy in predicting behavior. IQ and g (discussed in the next section) are correlated with many important social outcomes—individuals with low IQs are more likely to be divorced, have a child out of marriage, be incarcerated, and need long-term welfare support, while individuals with high IQs are associated with more years of education, higher status jobs and higher income.[18] Intelligence is significantly correlated with successful training and performance outcomes, and IQ/g is the single best predictor of successful job performance.[1][19]
[edit] General intelligence factor or g
There are many different kinds of IQ tests using a wide variety of test tasks. Some tests consist of a single type of task, others rely on a broad collection of tasks with different contents (visual-spatial, verbal, numerical) and asking for different cognitive processes (e.g., reasoning, memory, rapid decisions, visual comparisons, spatial imagery, reading, and retrieval of general knowledge). The psychologist Charles Spearman early in the 20th century carried out the first formal factor analysis of correlations between various test tasks. He found a trend for all such tests to correlate positively with each other, which is called a positive manifold. Spearman found that a single common factor explained the positive correlations among test. Spearman named it g for "general intelligence factor". He interpreted it as the core of human intelligence that, to a larger or smaller degree, influences success in all cognitive tasks and thereby creates the positive manifold. This interpretation of g as a common cause of test performance is still dominant in psychometrics. An alternative interpretation was recently advanced by van der Maas and colleagues.[20] Their mutualism model assumes that intelligence depends on several independent mechanisms, none of which influences performance on all cognitive tests. These mechanisms support each other so that efficient operation of one of them makes efficient operation of the others more likely, thereby creating the positive manifold.
IQ tasks and tests can be ranked by how highly they load on the g factor. Tests with high g-loadings are those that correlate highly with most other tests. One comprehensive study investigating the correlations between a large collection of tests and tasks[21] has found that the Raven's Progressive Matrices have a particularly high correlation with most other tests and tasks. The Raven's is a test of inductive reasoning with abstract visual material. It consists of a series of problems, sorted approximately by increasing difficulty. Each problem presents a 3 x 3 matrix of abstract designs with one empty cell; the matrix is constructed according to a rule, and the person must find out the rule to determine which of 8 alternatives fits into the empty cell. Because of its high correlation with other tests, the Raven's Progressive Matrices are generally acknowledged as a good indicator of general intelligence. This is problematic, however, because there are substantial gender differences on the Raven's,[22] which are not found when g is measured directly by computing the general factor from a broad collection of tests.[23]
[edit] Historical psychometric theories
Several different theories of intelligence have historically been important. Often they emphasized more factors than a single one like in g
[edit] Cattell-Horn-Carroll theory
Many of the broad, recent IQ tests have been greatly influenced by the Cattell-Horn-Carroll theory. It is argued to reflect much of what is known about intelligence from research. A hierarchy of factors is used. g is at the top. Under it there are 10 broad abilities that in turn are subdivided into 70 narrow abilities. The broad abilities are:[24]
- Fluid Intelligence (Gf): includes the broad ability to reason, form concepts, and solve problems using unfamiliar information or novel procedures.
- Crystallized Intelligence (Gc): includes the breadth and depth of a person's acquired knowledge, the ability to communicate one's knowledge, and the ability to reason using previously learned experiences or procedures.
- Quantitative Reasoning (Gq): the ability to comprehend quantitative concepts and relationships and to manipulate numerical symbols.
- Reading & Writing Ability (Grw): includes basic reading and writing skills.
- Short-Term Memory (Gsm): is the ability to apprehend and hold information in immediate awareness and then use it within a few seconds.
- Long-Term Storage and Retrieval (Glr): is the ability to store information and fluently retrieve it later in the process of thinking.
- Visual Processing (Gv): is the ability to perceive, analyze, synthesize, and think with visual patterns, including the ability to store and recall visual representations.
- Auditory Processing (Ga): is the ability to analyze, synthesize, and discriminate auditory stimuli, including the ability to process and discriminate speech sounds that may be presented under distorted conditions.
- Processing Speed (Gs): is the ability to perform automatic cognitive tasks, particularly when measured under pressure to maintain focused attention.
- Decision/Reaction Time/Speed (Gt): reflect the immediacy with which an individual can react to stimuli or a task (typically measured in seconds or fractions of seconds; not to be confused with Gs, which typically is measured in intervals of 2–3 minutes). See Mental chronometry.
Modern tests do not necessarily measure of all of these broad abilities. For example, Gq and Grw may be seen as measures of school achievement and not IQ.[24] Gt may be difficult to measure without special equipment.
g was earlier often subdivided into only Gf and Gc which were though to correspond to the Nonverbal or Performance subtests and Verbal subtests in earlier versions of the popular Wechsler IQ test. More recent research has shown the situation to be more complex.[24]
[edit] Controversies
While not necessarily a dispute about the psychometric approach itself, there are several controversies regarding the results from psychometric research. Examples are the role of genetics vs. environment, the causes of average group differences, or the Flynn effect.
One criticism has been against the early research such as craniometry.[25] A reply has been that drawing conclusions from early intelligence research is like condemning the auto industry by criticizing the performance of the Model T.[26]
Several critics, such as Stephen Jay Gould, have been critical of g, seeing it as a statistical artifact, and that IQ tests instead measure a number of unrelated abilities.[25][27] The American Psychological Association's report "Intelligence: Knowns and Unknowns" stated that IQ tests do correlate and that the view that g is a statistical artifact is a minority one.
[edit] Other theories
There are critics of IQ, who do not dispute the stability of IQ test scores or the fact that they predict certain forms of achievement rather effectively. They do argue, however, that to base a concept of intelligence on IQ test scores alone is to ignore many important aspects of mental ability.[1]
On the other hand, Linda S. Gottfredson (2006) has argued that the results of thousands of studies support the importance of IQ for school and job performance (see also the work of Schmidt & Hunter, 2004). IQ also predicts or correlates with numerous other life outcomes. In contrast, empirical support for non-g intelligences is lacking or very poor. She argued that despite this the ideas of multiple non-g intelligences are very attractive to many due to the suggestion that everyone can be smart in some way.[28]
[edit] Multiple intelligences
Howard Gardner's theory of multiple intelligences is based on studies not only of normal children and adults but also by studies of gifted individuals (including so-called "savants"), of persons who have suffered brain damage, of experts and virtuosos, and of individuals from diverse cultures. This led Gardner to break intelligence down into at least eight different components: logical, linguistic, spatial, musical, kinesthetic, interpersonal, intrapersonal, naturalist and existential intelligences. He argues that psychometric tests address only linguistic and logical plus some aspects of spatial intelligence.[1] A major criticism of Gardner's theory is that it has never been tested, or subjected to peer review, by Gardner or anyone else, and indeed that it is unfalsifiable.[29] Others (e.g. Locke, 2005) have suggested that recognizing many specific forms of intelligence (specific aptitude theory) implies a political—rather than scientific—agenda, intended to appreciate the uniqueness in all individuals, rather than recognizing potentially true and meaningful differences in individual capacities. Schmidt and Hunter (2004) suggest that the predictive validity of specific aptitudes over and above that of general mental ability, or "g", has not received empirical support.
Howard Gardner mentions in his Multiple Intelligences The Theory in Practice[30] book, briefly about his main seven intelligences he introduced. In his book, he starts off telling describing Linguistic and Logical Intelligence because he believed in society, we have put the two subjects on a pedestal. However, Gardner believes every of the intelligences he found has equality. Note: At the time of the publication of Gardner's book Multiple Intelligences The Theory in Practice, naturalist and existential were not mentioned.
Linguistic Intelligence: The kind of ability exhibited in its fullest form, perhaps, by poets.
Logical-Mathematics Intelligence: Is logical and mathematical ability, as well as scientific ability. Howard Gardner believed Jean Piaget may have thought he was studying all intelligence, but in truth, Piaget was really only focusing on the logical mathematical intelligence.
Spatial Intelligence: The ability to form a mental model of a spatial world and to be able to maneuver and operate using that model.
Musical Intelligence: Leonard Bernstein had lots of it; Mozart, presumably, had even more.
Bodily-kinesthetic intelligence: The ability to solve problems or to fashion products using one's whole body, or parts of the body. For example, dancers, athletes, surgeons, craftspeople, etc.
Interpersonal Intelligence: The ability to understand people. People who are well in interpersonal are most likely teachers, politicians, clinicians, religious leaders, etc.
Intrapersonal Intelligence: A correlative ability, turned inward. It is a capacity to form an accurate, veridical model of oneself and to be able to use that model to operate effectively in life.
[edit] Triarchic theory of intelligence
Robert Sternberg proposed the triarchic theory of intelligence to provide a more comprehensive description of intellectual competence than traditional differential or cognitive theories of human ability.[31] The triarchic theory describes three fundamental aspects of intelligence. Analytic intelligence comprises the mental processes through which intelligence is expressed. Creative intelligence is necessary when an individual is confronted with a challenge that is nearly, but not entirely, novel or when an individual is engaged in automatizing the performance of a task. Practical intelligence is bound in a sociocultural milieu and involves adaptation to, selection of, and shaping of the environment to maximize fit in the context. The triarchic theory does not argue against the validity of a general intelligence factor; instead, the theory posits that general intelligence is part of analytic intelligence, and only by considering all three aspects of intelligence can the full range of intellectual functioning be fully understood.
More recently, the triarchic theory has been updated and renamed the Theory of Successful Intelligence by Sternberg.[32][33] Intelligence is defined as an individual's assessment of success in life by the individual's own (idiographic) standards and within the individual's sociocultural context. Success is achieved by using combinations of analytical, creative, and practical intelligence. The three aspects of intelligence are referred to as processing skills. The processing skills are applied to the pursuit of success through what were the three elements of practical intelligence: adapting to, shaping of, and selecting of one's environments. The mechanisms that employ the processing skills to achieve success include utilizing one's strengths and compensating or correcting for one's weaknesses.
Sternberg's theories and research on intelligence remain contentious within the scientific community.[34][35][36][37]
[edit] Piaget's theory and Neo-Piagetian theories
In Piaget's theory of cognitive development the focus is not on mental abilities but rather on a child's mental models of the world. As a child develops, increasingly more accurate models of the world are developed which enable the child to interact with the world better. One example being object permanence where the child develops a model where objects continue to exist even when they cannot be seen, heard, or touched.
Piaget's theory described four main stages and many sub-stages in the development. Degree of progress through these is correlated with but is not identical with psychometric IQ.[38][39]
Neo-Piagetian theories of cognitive development expand Piaget's theory in various ways such as also considering psychometric-like factors such as processing speed and working memory, "hypercognitive" factors like self-monitoring, more stages, and more consideration on how progress may vary in different domains such as spatial or social.[40][41]
Piaget's theory has been criticized for the age of appearance of a new model of the world, such as object permanence, being dependent on how the testing is done (see the article on object permanence). More generally, the theory may be very difficult to test empirically due to the difficulty of proving or not proving that a mental model is the explanation for the results of the testing.[42]
[edit] Emotional intelligence
Emotional intelligence is an argued ability, capacity, skill or, a self-perceived ability to identify, assess, and control the emotions of oneself, of others, and of groups. Different models have been proposed for the definition of emotional intelligence and there is disagreement about how the term should be used. The concept is controversial (Locke, 2005), with some seeing it as a skill or form of personality rather than intelligence, and its predicative ability, especially after controlling for the effects of IQ and the Big Five personality traits, is disputed.
[edit] Latent inhibition
Latent inhibition has been related to elements of intelligence, namely creativity and genius.
[edit] Evolution of intelligence
Our hominid and human ancestors evolved large and complex brains exhibiting an ever-increasing intelligence through a long evolutionary process. Many different explanations have been proposed.
[edit] Improving intelligence
Eugenics is a social philosophy which advocates the improvement of human hereditary traits through various forms of intervention.[43] Conscious efforts to influence intelligence raise ethical issues. Eugenics has variously been regarded as meritorious or deplorable in different periods of history, falling greatly into disrepute after the defeat of Nazi Germany in World War II.[citation needed]
Neuroethics considers the ethical, legal and social implications of neuroscience, and deals with issues such as the difference between treating a human neurological disease and enhancing the human brain, and how wealth impacts access to neurotechnology. Neuroethical issues interact with the ethics of human genetic engineering.
Because intelligence appears to be at least partly dependent on brain structure and the genes shaping brain development, it has been proposed that genetic engineering could be used to enhance the intelligence, a process sometimes called biological uplift in science fiction. Experiments on mice have demonstrated superior ability in learning and memory in various behavioral tasks.[44]
Transhumanist theorists study the possibilities and consequences of developing and using techniques to enhance human abilities and aptitudes, and individuals ameliorating what they regard as undesirable and unnecessary aspects of the human condition.
[edit] Animal and plant intelligence
Although humans have been the primary focus of intelligence researchers, scientists have also attempted to investigate animal intelligence, or more broadly, animal cognition. These researchers are interested in studying both mental ability in a particular species, and comparing abilities between species. They study various measures of problem solving, as well as mathematical and language abilities. Some challenges in this area are defining intelligence so that it means the same thing across species (e.g. comparing intelligence between literate humans and illiterate animals), and then operationalizing a measure that accurately compares mental ability across different species and contexts.
Wolfgang Köhler's pioneering research on the intelligence of apes is a classic example of research in this area. Stanley Coren's book, The Intelligence of Dogs[unreliable source?] is a notable popular book on the topic.[45] Nonhuman animals particularly noted and studied for their intelligence include chimpanzees, bonobos (notably the language-using Kanzi) and other great apes, dolphins, elephants and to some extent parrots and ravens. Controversy exists over the extent to which these judgments of intelligence are accurate.[citation needed]
Cephalopod intelligence also provides important comparative study. Cephalopods appear to exhibit characteristics of significant intelligence, yet their nervous systems differ radically from those of most other notably intelligent life-forms (mammals and birds).
It has been argued that plants should also be classified as being intelligent based on their ability to sense the environment and adjust their morphology, physiology and phenotype accordingly.[46][47]
[edit] Artificial intelligence
Artificial intelligence (or AI) is both the intelligence of machines and the branch of computer science which aims to create it, through "the study and design of intelligent agents"[48] or "rational agents", where an intelligent agent is a system that perceives its environment and takes actions which maximize its chances of success.[49] Achievements in artificial intelligence include constrained and well-defined problems such as games, crossword-solving and optical character recognition. General intelligence or strong AI has not yet been achieved and is a long-term goal of AI research.
Among the traits that researchers hope machines will exhibit are reasoning, knowledge, planning, learning, communication, perception, and the ability to move and manipulate objects.[48][49] In the field of artificial intelligence there is no consensus on how closely the brain should be simulated.

지능
[ intelligence , 知能 ]
- 문제해결 및 인지적 반응을 나타내는 개체의 총체적 능력.
지능은 학자에 따라 다르게 정의되고 있다. L.M.터먼은 지능을 ‘추상적 사상을 다루는 능력’이라고 정의하였고, D.웩슬러는 ‘유목적적으로 행동하고, 합리적으로 사고하고, 환경을 효과적으로 다루는 개인의 종합적 능력’이라고 정의하고 있다.
지능과 관련된 이론들로는 지능을 한 개의 일반적 요인과 여러 개의 특수요인으로 구성되어 있다고 보는 C.E.스피어만의 2인자설과 여러 개의 특수요인이 기초 정신능력이라고 보는 L.L.서스톤의 중다요인론이 있다. 근래에 J.P.길포드는 지능이 120개의 요소로 구성되어 있다는 복합설을 제안하였다. 스턴버그에 의하면 지능은 아동의 지능검사에서 드러나는 ‘구성적 요소’뿐만 아니라, ‘경험적 요소’와 ‘상황적 요소’가 추가된다고 한다. ‘구성적 요소’는 정보를 얼마나 효율적으로 처리하고 분석하는가 하는 것이다. 이것은 지능의 ‘비판적’ 측면인데 어떻게 문제에 접근하며, 그것을 어떻게 해결하며, 결과를 어떻게 평가하는가를 말해준다. 이 분야에서 강한 사람들은 지능검사 점수가 높으며, 논쟁을 잘 한다. ‘경험적 요소’는 새로운 정보를 이미 알고 있는 정보와 비교하거나 사실들을 새로운 방법으로 경합시키는 통찰력을 말한다. 경험적 요소가 발달되면 새로운 단어의 해독과 같은 익숙하지 않은 과업에 몰두하도록 정신이 자유롭다.‘상황적 요소’는 환경에 어떻게 대처하는가 하는 실제적이고 현실세계적인 측면이다. 성인이 될수록 상황을 판단하고 무엇을 할 것인지 결정하는 상황적 요소가 중요하다.
근래는 지능발달과 환경적 경험의 상대적 중요성에 대한 여러 주장이 대두되고 있다. 헌트는 일란성 쌍둥이 연구를 통해 아동의 초기 환경이 IQ점수상의 차이를 결정한다고 주장하였다. B.S.블룸도 지능의 상당한 부분은 환경의 힘에 의해 변화될 수 있으며, 이러한 변화 가능성은 어릴 때일수록 크다고 주장하였다. 지능검사의 문항이 문화적으로 중립적인 내용을 담고 있지 않으면, 지능검사에 자신의 문화적 경험이 반영된 집단의 지능이 상대적으로 높게 나온다는 우려가 제기되고 있다. 지능과 학습은 밀접한 관계를 맺고 있으나, 학업성취도는 지능 외에도 다른 다양한 요인들에 의해 설명되기 때문에 학교에서의 다양한 학습조건은 학교학습에서의 지능의 역할을 증가 또는 감소시킬 수 있다.
