1. The role of observational research in describing behavior and generating hypotheses – the case of Kitty Genovese (1964) 

2. Classification of observational methods:
 

a. Observation without intervention – the naturalistic observation
 

b. Observation with intervention:

• Participant observation – Festinger and the cult (Festinger, Riecken, & Schachter, 1956)

• Structured observation – attachment theory; Piaget’s studies; Lorenz and his geese

• The field experiment – love on the high bridge (Dutton & Aron, 1974)
