Maturation is a threat to internal validity stemming from either long-term or short-term physiological changes occurring within the participants that may influence the dependent variable.

What are physiological changes?</h3>
Ageing causes physiological changes in all organ systems. Arteriosclerosis develops, blood pressure rises, and cardiac output declines. Lung function is compromised, vital capacity is reduced, and expiratory flow rates are slowed.
Pregnancy causes a number of physiological changes in the mother, such as an increase in fat and total body water, a drop in plasma protein concentrations, particularly albumin, an increase in blood volume, cardiac output, and blood flow to the kidneys, and a decrease in blood pressure.

Answer:
The answer is: an ethnography.
Explanation:
Ethnography is a research method that consists of the study of the everyday life of a group of people. When social researchers first began using this method, it was common for them to live with the group they were studying over a period of years, since they focused on the study of foreign cultures. However, although ehnography still implies the submersion of the researcher into the community or culture he is studying, it doesn't necessarily have to be a foreign non occidental culture.
Within this method, researchers can use several research techniques to gather data, participant and non participant observation, interviews, etc.
