>> LQ 2.4 How is research on child development conducted?

As we mentioned at the beginning of this chapter, theories must be subjected to rigorous testing before we are willing to accept them as reliable and valid. In this section we look at how researchers study children and adolescents. Because each research method has its own advantages and disadvantages, there isn’t one best way to study development. Rather we look for the most appropriate method to investigate the particular topic we want to examine. After describing a number of research methods used to study children and adolescents, we consider the ethical issues that come along with conducting research with this population.
