What are internal and external factors that affect humans called?

• A. Pressures.
• B. Stimuli.
• C. Catalysts.
• D. Influences.

Answer: (A)

Internal and external factors that influence behavior are described as pressures. The idea is that a pressure is a force or constraint that pushes someone toward thinking or acting in a certain way. Internal pressures come from within, like personal goals, expectations, anxiety, or motivation. External pressures come from outside, such as deadlines, social norms, family or peer expectations, or environmental demands. Together, these pressures shape decisions, performance, and how someone reacts to situations. Stimuli are triggers that prompt a response, but they don’t always convey the sense of ongoing demands or constraints. Catalysts speed up change but aren’t about the affecting forces in everyday life; influences are broad and less specific about the push or pull these factors exert.
