Theory
A theory is a broad explanatory framework that accounts for larger bodies of data and interprets phenomena. In psychological research, working with theories is a basic, essential ingredient, serving as the foundation from which specific hypotheses are derived and tested. Crucially, theories can be supported by evidence but can never be definitively proved, and disconfirming a single hypothesis does not necessarily mean that the broader theory has been disproved.

A researcher observes that employees who take short, 15-minute breaks every 90 minutes report higher job satisfaction and are more productive than employees who work for four hours straight. After several controlled experiments confirm this pattern, the researcher proposes a comprehensive explanation. Which of the following statements best represents a scientific theory based on these findings?
A psychologist repeatedly observes that individuals in a group are less likely to help someone in an emergency compared to when they are alone. After reviewing dozens of studies and conducting controlled experiments that replicate this finding, the psychologist seeks to explain this phenomenon. Which of the following statements best represents a theory derived from these observations?
