Question

To compare moral reasoning skills of younger and older children, Professor Hauten tested and retested a group of children from the time they were 4 until they reached the age of 12. The professor conducted a ________ study.

Answer 1

The answer is a longitudinal study.

Step-by-step explanation:

Longitudinal studies are carried out over a prolonged period of time, using the same subjects and analysing the same factors. These are mostly done to examine changes in behaviour, as well as medical studies determining health effects.

The greatest advantage is that it reflects accurate results, as they involve close, rigorous observation. However, longitudinal studies are naturally very time-consuming and could be expensive.
