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.
<h3>
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:
- Long working hours.
- Small pay
Explanation:
From the source shown above, the young girls had to work really long hours from 5 am to around 7 pm. Even though they were granted breakfast and lunch hours, this is still a long time to work. Long work hours have been shown to drain a person and lead to fatigue, lack of attentiveness and lower productivity.
The young girls also received little pay for the amount of hours of work they put in. The doffers for instance, were paid $2 a week for being on duty for nearly fourteen hours a day. Assuming this is a 6 day work week, that would translate to less than 3 cents per hour.
These working conditions took such a toll on the young ladies that they were able to argue the case for a reduction in work hours by their presence.
