mean `to look within` this is also know as self –observation
method . It is not possible to understand the inner feelings and
experiences of the person . Here the subject is asked to
systematically observe his own behavior and report the same
:this is later analyed to understand behavior .

how he feels.the patient will try to look within and recall what
happended and how he is presently feeling . This information
will help for better treatment .

or laboratory
• Demarits :

retarded people , because they cannot introspect .
• it is purely private affair and cannot be verified by other observers.
• It many cases ,the patient may not have the insight to know about
their conditions or language to describe them accurately .

which is procedure by an external object .

31. • Observational method :-
observation is the objective method of studying the behavior of
individuals . It consists of , preception of an individual`s behavior
under natural conditions by the other individual and the
interpretation and analyzes of this method the observer observes
and collects the data.

`s temperature ,pulse ,blood pressure, facial expresasions,
restlessness, etc .

time, energy and money.

33. • Experimental Method
Experimental method is considered as the most scientific and objective method of
studying behavior. The word experiment comes from a Latin word meaning 'to try',
'put to test'. Therefore, in experimentation we try or put to test the material or
phenomenon, the characteristics of consequences of which we wish to ascertain. The
use of this method has raised psychology to the status of an experimental science
like physics, chemistry and physiology. In psychology, experimental study is used to
study the cause-and-effect relationship regarding the nature of human
behavior , i.e. the effect of anxiety on the human behavior . To study the cause-
and- effect relationship the psychologists use objective observations under
controlled conditions to observe actions or behaviors of individuals . from these
observation certain conclusions are drawn and theories or principles established.

• Requires two persons ,the experimenter and the subject or the person ,whose
behavior is observed .
• experimentation should be done on living organisms.
• all experiments are conducted under controlled conditionds.

34. Merits :-

method .moreover handling of this method demands
specialized knowledge and skill.
