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

4. Physiological Test : The psychological and physiological activities are closely related. Notes
They influence one another. As such, a person’s psychological activities can be ascertained
by his physiological activities. In the meantime, the scientists have made several tools
by which changes in the body can be measured; for example, sphygmograph,
plenthysmograph, electro-cardiograph, pheumograph, electromyogram, psycho-
galvanometer, electro-encephalogram, etc. These tools can be used to read the
physiological changes occurring in a particular situation to study his psyche and his
interactions. Thus, the hidden traits of one’s personality are found out.
32.3.5 Use of Personality Test
At present, the personality tests are used in several fields. The important fields are : education,
industry, commerce, psychology and armed forces.
Use in the Field of Education
(1) For selection of students for admission.
(2) For finding out interests, aptitudes, desires and needs of the students.
(3) For knowing the internal mental condition and social relations of students.
(4) For diagnosis and remedies of personal problems of the students.
(5) For providing individual, educational and vocational guidance to the students.
32.3.6 Limitations of Personality Test

The first thing about the personality tests is that the psychologists do not hold uniform views on the
concept or personality. Second, the personality traits can not be measured correctly. Clarification is
as follows :
(l) Most personality tests measure only limited personality traits, so no one test can be used to
measure all personality traits correctly.
(2) The so far published projective tests for personality measurement are very difficult to administer
and analyse.
(3) The data of personality testing are influenced by several factors, so correct measurement of a
person’s personality at any given time can not be done properly.
(4) All the personality tests that have been constructed so far, have a question mark on their
validity.
(5) No two personality tests give the same results, so there is question mark on their validity.
(6) The administration and analysis of all personality tests depend more on the measurer, so they
can not be called fully objective.
(7) The personality of a person is a dynamic organisation. The personality measured at any given
time can not be considered his permanent or stable personality.

32.4 Measurement of Intelligence

32.4.1 Concept of Intelligence
The psychologists do not hold uniform view on the concept of intelligence. Different psychologists
have accepted it in the form of ability of different mental activities, and some psychologists have
taken it in the form of capacity of different mental activities. It is evident that they accept intelligence
