What kind of activities do developmental psychologists do to research about human development?
Answer 1:

I can speak to this with respect to my subfield of cognitive science, which is spatial cognition. Some researchers proposed that people have a native geometric module in their mind that allows them to process their own location within a space by making accurate geometric calculations. In order to show that this is native to human beings, these spatial cognition researchers used babies in their studies. The idea is that babies have not been exposed to too much and are still exhibiting more nature than nurture. Researchers that believed in the geometric module thought that young infants could not use landmarks to locate things in space. However, some researchers showed that babies combine geometric information with landmark information. The experimenters used cue cards as landmarks. All the cards were blue on one side and one was green on the other. The children were spun around and told to find the green card. The children were able to do this in a large room.
