Behaviour: Aggregate of all the responses made by individuals

Methods to study human behaviour :

Introspection Method Observation Method Experimental Method Case Study Method Survey Method Genetic Method

Introspection Method

• A self-observation method to express inner feelings• The word introspection means ‘to look within’

Demerits• Can’t verify the reports given by the observer• Not applicable for children and mentally disordered

persons

Observation Method

• Observation is made in their natural environment by trained persons

• Studies children, mentally ill and unconscious patients

Demerits• Chances of subjective report• It is an time expensive method

Experimental Method• A multi-step and most objective method to study

behaviour• Effect of independent variable on the dependent

variables are studied under the control of extraneous variable

Demerits

• Can’t be conducted outside laboratory

• Confounding Variables and Placebo Effect• Very expensive and time consuming

Case Study Method

• Detailed information collected & interpreted• Widely used in clinical and educational settings for

investigation and exploratory research

Demerits• Can’t generalize the results to the wider population• Researchers' own subjective feeling may influence

Survey Method

• Gathers information from large number of people• Ease of analysis & graphical representation

Demerits• Difficult to handle specialised cases• Requires too much time and manpower

Genetic Method

• Makes use of the results from earlier stages of life and various heredity related issues

• Involves cross-sectional study and longitudinal study

Demerits• No experimental verification• Doesn’t work well in mutation
