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

• Not applicable for children and mentally disordered persons

4. • Observation is made in their natural environment by

5. • 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

6. • 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

7. • Gathers information from large number of people
• Ease of analysis & graphical representation
Demerits
• Difficult to handle specialised cases
• Requires too much time and manpower

8. • 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
