 DEFINITIONS OF INTELLIGENCE

Lewis Terman: ‘An ability to think

on an abstract level is called
Intelligence.’

David Wechsler: ‘Intelligence is the

aggregate or global capacity of an
individual to act purposefully, to think
rationally, and to deal effectively with his
environment.’
 PERSPECTIVES ON INTELLIGENCE

 Intelligence as a single, general ability : Psychologists who believe

in the unitary notion of intelligence explain that only the functions of
intelligence take different forms but basically it is the same ability.
Alfred Binet, Lewis Terman, David Wechsler believed that
intelligence is a single entity.

 Intelligence as a set of multiple abilities : Psychologists like E. L.

Thorndike, Louis Thurstone, Charles Spearman, etc. came up with the
notion that multiple abilities are involved in intelligence.
E. L. Thorndike : E. L. Thorndike
put forth three independent abilities
that can be called intelligence.
These abilities are (1) Abstract
intelligence (2) Social intelligence
and (3) Concrete intelligence.

Louis Thurstone:
He proposed seven primary abilities,
each independent of the other that can
be called intelligence. These seven
primary abilities are (1) Verbal
comprehension (2) Word
fluency (3) Number facility (4) Spatial HOWARD GARDNER
visualization (5) Associative memory
(6) Perceptual speed and (7) Reasoning. Raymond Cattell and John Horn
Louis Thurstone also devised the test to : Raymond Cattell with his student
measure these abilities. John Horn proposed a theory of
intelligence explaining two types of
intelligence viz.
Charles Spearman : In 1927, (Fluid intelligence and (2)

daily work. Whereas specific factor
includes abilities which are required
to solve problems in specific areas.
HISTORY OF MEASUREMENT OF INTELLIGENCE

Paul Broca and Sir Francis Galton

 First scientists to think about measuring intelligence.

 1880s administered a battery of tests measuring variables
such as head size, reaction time, visual accuracy, auditory
threshold, breathing capacity, etc.
 Determine intelligence by measuring the size of the human
skull.
 He assumed that the larger the skull, the smarter the person.
 But Sir Francis Galton’s test did not prove very useful for the
measurement of intelligence.
RAYMOND CATTELL

 Raymond Cattell used the term ‘mental test’

 intelligence is best measured through sensory tasks, but
expanded his mentor’s ideas by emphasizing that test
administration must be standardized so that results are
comparable from person to person and from time to
time.
Alfred Binet
 Binet published the first scale of intelligence in
1905.
 ‘Father of Intelligence Test’
 Binet- Simon Intelligence Scale consists of
several components such as logical reasoning,
finding rhyming words and naming objects.
 This scale was revised in 1908 and again in
1911.
Lewis Terman

 From Stanford University revised the Binet-Simon Intelligence Scale in

1916.
 Established new age norms and extended the upper age limit of the
scale
 This revised test was known as Stanford Binet Test.
 This test was revised in 1937, 1960, 1972, 1986 and 2004.

Robert Yerks

 Prepared Army Alpha and Army Beta intelligence tests.

 These intelligence tests were used while recruiting soldiers in the army.
David Wechsler
 1939, published the Wechsler- Bellevue
Intelligence Scale.
 Revised in 1955 and was renamed as Wechsler
Adult Intelligence Scale (WAIS).
 WAIS is a test designed to measure intelligence
of adults and older adolescents.
 The fourth edition of this test (WAIS-IV) was
released in
2008 by Karl Pearson.
 David Wechsler also developed an intelligence
test to measure the intelligence of children.
 This test is known as Wechsler Intelligence
Scale for Children (WISC).
 Measurement Of Intelligence

Mental Age:
The age at which

years) prepared for that
 He devised a test comprising of items specified age
for different age group levels and measured
mental age of various people. Esha 10 12 12

 Mental age can be defined as the age at which

INTELLIGENCE QUOTIENT
 The concept of Intelligence Quotient (I.Q.) was introduced by
German psychologist William Stern in 1912 as a ratio of
Mental Age (M.A.) to Chronological Age (C.A.).
 Stern computed I.Q. by the formula.
 Later, Terman refined the formula of I.Q. by multiplying the
ratio of M.A. and C.A. by 100. This formula is as follows :
Intelligence Quotient (I.Q.) = (Mental Age (M.A.) X 100
(Chronological Age (C.A.)
THE CONCEPT OF I.Q. IS EXPLAINED WITH
THE HELP OF THE FOLLOWING EXAMPLES :

INDIVIDUAL TESTS OF INTELLIGENCE

 Intelligence tests that can be administered to a

single individual at a time are called individual
tests of intelligence.
 Binet’s Scale of Intelligence
 Wechsler Scale of Intelligence
 Dr. Bhatia’s Performance Test of Intelligence
 Arthur Point Scale
 Koh’s Block Design, etc. are some of the
examples of individual tests of intelligence.
ADVANTAGES OF INDIVIDUAL TESTS :
 A rapport with a client .
 additional information about the client’s feelings, moods
and expressions during testing.
 Capable of measuring creative thinking, compared to
group test.

Disadvantages Of Individual Tests :

•Time consuming and costly to administer.
•A trained and skillful examiner to administer, score and
interpret them.
GROUP TESTS OF INTELLIGENCE
 Intelligence tests that can be administered to
more than one person at a time are called
group tests of intelligence.
 Group tests of intelligence were devised to
recruit large number of soldiers in the army
during the First World War.
 Group tests are useful mainly for mass
testing.
 Army Alpha Test
 Army General Classification Test
 Raven’s Standard Progressive Matrices, etc.
are some of the examples of group tests of
intelligence.
ADVANTAGES OF GROUP TESTS :
 Less time consuming and economical.
 The role of the examiner is minimal.
 Need not any specialized training.

DISADVANTAGES OF GROUP TESTS :

 less opportunity to establish rapport, obtain co- operation and

maintain interest of the clients.
 Compared to individual tests, group tests are less capable of
measuring creative aspect of intelligence.
VERBAL TESTS OF INTELLIGENCE :
 Intelligence tests that use language (words or numbers) for
measuring intelligence are called verbal tests of intelligence. In
these tests subjects are required to respond verbally to test
items.
 Army Alpha Test
 Wechsler’s Adult Intelligence Scale (WAIS), etc. are some of
the examples of verbal tests of intelligence.
ADVANTAGES OF VERBAL TESTS :
 To measure higher mental abilities.
 To differentiate between people having average intelligence and people
having above average intelligence.

DISADVANTAGES OF VERBAL TESTS :

 These tests cannot be given to people having different linguistic background,
illiterate people and small children.
 These tests are culture bound and therefore cannot be used in other cultures.
NON-VERBAL TEST :
 Intelligence tests that use pictures, designs,
material objects, etc. to measure intelligence
are called non-verbal tests of intelligence.
 language is not used to measure intelligence.
 subjects are not required to respond verbally
to test items.
 Koh’s Block Design Test, Alexander’s Pass-
along test, Merril Palmer
 Block Building test, Dr. Bhatia’s Non-Verbal
Test of Intelligence, etc. are some of the
examples of performance tests of non-verbal
tests of intelligence.
 Raven’s Standard Progressive Matrices,
Raven’s Coloured Progressive Matrices, etc.
are some of the examples of paper pencil
tests of non-verbal tests of intelligence.

Advantages of non-verbal tests :

 Non-verbal tests can be given to people having

different linguistic background, illiterate people
and small children. Performance tests are
especially useful to measure intelligence of
differently abled people.
 Culture free and therefore can be used in other Specimen of paper-pencil test

Disadvantages of non-verbal tests :

 Non-verbal tests of intelligence are less suitable to

measure higher and subtle mental abilities.
 Non-verbal tests of intelligence are less suitable to
differentiate between people having average

NEW TRENDS IN INTELLIGENCE

1. SOCIAL INTELLIGENCE
 Chetan, a very intelligent adult, fails to cope up with the simple
challenges in life. He feels very lonely. His relations with parents,
wife and colleagues are extremely problematic.
 Sagar, a bank manager has good relations with others. But,
sometimes he becomes angry without reason and talks rudely to his
subordinates.
 Anil, a young entrepreneur, got very less marks in his degree
examination. However, by his hard work, excellent communication
skills and ability to maintain friendly relations with all, he has
become successful in his business and is living his life very happily.
 E.L. Thorndike
 A psychologist from Columbia University
proposed the term social intelligence for the first
time in 1920.
 Howard Gardner included ‘inter personal
intelligence’ in his multiple intelligence theory.
 According to Karl Albrecht, “Social intelligence is
the ability to get along well with others, and to
get them to cooperate with oneself.”
EMOTIONAL INTELLIGENCE
 Megha is always afraid of getting less marks in
examinations. Therefore, she always becomes restless
and avoids going to college.
 Shailesh, an ordinary worker in a textile mill earns
10,000 salary per month. Though having some financial
problems, he never feels anxious, he understands the
problems of others, helps needy people and lives his life
happily.
DEFINITION OF EMOTIONAL INTELLIGENCE
 John Mayer and Peter Salovey: Emotional Intelligence as the ‘ability
to perceive and monitor one’s own and others emotions, to
discriminate among them and to use this information to guide one’s
thinking and action.’
 They presented an ability based model of emotional intelligence and
defined emotional intelligence as a set of following cognitive
abilities :
 Perceiving emotions
 Using emotions
 Understanding emotions
 Managing emotions
 ARTIFICIAL INTELLIGENCE

 Artificial Intelligence is enabling machines or the software programmes

running those machines to think and learn through experience just like
human’s intelligence.
 Artificial Intelligence is used on a large scale to perform various daily
routine tasks as well as to solve various critical problems.
EXAMPLE
 Speech recognition
 Natural language processing

 Spam filtering from emails

 Medical diagnosing

 Detecting frauds in economic

transactions
 Weather forecasting, etc.
 CONCLUSION

 Intelligence means a capacity to

understand the world, think
rationally, and use available
resources effectively when faced
with challenges.
 Today, the intelligence tests are
used in diverse fields.
