Question

Quizplus · Accepted Answer

Living in impoverished environments is the most common cause of a decline in IQ during school years. Children living in poverty may experience chronic stress, lack of access to quality healthcare and nutrition, and limited educational opportunities, all of which can negatively impact cognitive development. Accidental injury to the brain and chronic illness can also cause a decline in IQ but are not as commonly seen as living in poverty. Ineffective schools may also contribute to lower IQ scores, but they usually affect a larger group of students rather than individual cases.
