If you are a social psychologist studying how groups affect a person's behavior, which of the following would be the most effective way of gathering information? observe a person in the presence of others

ask a person to describe her social relations

survey people's attitudes about social influence

talk to parents of elementary school students

Observe a person in the presence of others.

Explanation:

Due to the question asking what would be the most effective way of getting information on how groups affect a person's behavior, it would be best to study that itself, which will yield more accurate results than a retelling of experiences (memories are often faulty to a point) or a talk to parents, who can be very biased, for example.

Hope this helped!
