Document Summary
Lecture 4: observation- where we watch participants develop in action. The kind you want to collect as a developmental. Research methods researcher: naturalistic observation- going into the natural environment under normal circumstances. We have to be careful not to affect environment. Example: watching children on a playground: structured observation- researcher plays much more of an active role; tells participant what to do. Sometimes in natural contexts, mostly in the lab. Example: still face experiment- measures the quality of mother infant relationship and interactions: problems: Observer influence- when you know you"re being watched, you are on good behavior that is socially desirable. Observer bias- as a researcher, you have to recognize that you come in with preexisting ideas that you want to see in the data. Example: you believe boys are more aggressive than girls, when you see a boy be aggressive you write it down but don"t write it down when a girl is.
