Unit 32 : Measurement of Attitude, Aptitude, Personality and Intelligence

measurement of one’s intelligence. This is the reason that in some of the intelligence tests the deviation Notes
intelligence quotient is calculated in place of intelligence quotient. Deviation intelligence quotient is
a kind of standard score whose mean (M) = 100, and standard deviation is (S.D., σ ) = 16.
32.4.8 Types of Intelligence Test
Intelligence tests are classified on two bases : number of subjects or examinees, and forms of
presentation of the tests. Intelligence tests are divided into two categories on the basis of number of
the subjects or examinees : individual intelligence tests and group intelligence tests. They are also
classified into two types on the basis of their presentation : verbal intelligence tests and non-verbal
intelligence tests. These two classifications of intelligence tests can be understood by the following
chart collectively :

Here we present the general introduction of intelligence tests.
Individual and Group Intelligence Tests
The intelligence tests are divided into two types on the basis of number of subjects or examinees :
individual intelligence tests and group intelligence tests.
1. Individual Intelligence Test : These are those intelligence tests which can be administered on
only one subject or examinee at one time. In these tests, the examiner first establishes rapport
with the subject and brings him into normal mental condition; he frees him from all kinds of
fears and anxieties. After this, he gives directions about the test, and at last, asks him to answer
the questions included in the test. Some of the important tests of this type are : Stanford-Binet
test of Intelligence, Wechsler Intelligence Scale, Merril and Palmer Intelligence Scale, Pinter-
Peterson Performance Scale, Merril-Palmer Block Building Test and Porteus Maze Test.
The chief characteristic of these tests is that there is establishment of rapport between the
examiner and the examinee in their administration, the examinee is free from all kinds of fears
and anxieties, and he answers in normal state of mind.
2. Group Intelligence Test : These are those intelligence tests which can be administered one
large number of subjects at a time. The administration of these tests does not require the
examiner to establish rapport with the subjects. He distributes the intelligence tests himself or
gets them distributed. The directions about the test are printed on the tests themselves, or they
are printed separately for distribution. Some of such important tests are : Army Alpha Test,
Burt’s Group Intelligence Test, jalota’s Intelligence Test, Raven’s Progressive Matrix, Cattell’s
Culture Free Test and Army Beta Test.
The chief characteristic of these tests is that they can be constructed and standardised easily.
Second, their administration is easy, and does not require specialists. Third, their administration
can be done on hundreds of subjects together at one time. As a result, their administration
needs less time, energy and money; they are less expensive. Fourth and last, they are especially
suitable for selection and classification of students and persons.
