Section B Biological Rhythms

Question 1

Ethnocentrism

Answer 1

Research is ethnocentric when the sample is from one country (Preckel- German high school).

Research is not ethnocentric when the results are useful for people from all cultures (Melatonin for phase advance).

Research is not ethnocentric when the procedure is controlled so cultural values won’t affect result (Siffre lived in a cave for 2 months, light only from bulb and only contact with the outside was when he told them when he woke and went to sleep- light levels in his country won’t affect this).

Research is not ethnocentric when it tests biological factors that are the same for everyone (Czeisler- all shift workers will prefer phase delay).
