Explanation:

In an experiment, the independent variable is what the researcher manipulates. Here, Dr. Yondu manipulates whether children receive a social - skills intervention or not. The emotional stability questionnaire results are measured to see the impact of the social - skills intervention. So, the independent variable measures the impact of the social - skills intervention (nurture factor as it's an environmental influence).
