Which theory states that personality is a result of biology and the environment, acknowledging situational factors?

• A. Trait theory
• B. Biological theory
• C. Interactionist theory
• D. Social learning theory

Answer: (C)

Think about how a person’s behavior can come from both what they’re wired with biologically and what’s happening around them. The idea that personality results from the ongoing interplay between biology (genetics, physiology) and the environment, with how we act shaped by the specific situation, is known as interactionist theory. It captures the sense that traits may exist, but their expression changes with context and circumstances. For example, someone might be naturally shy, yet in a familiar, supportive setting they become more outgoing, while in a stressful situation they might retreat again. That flexibility across different contexts is the hallmark of this view.

By comparison, trait theory focuses on stable, enduring characteristics that stay the same across situations; biological theory emphasizes heredity and brain processes as the main drivers with less emphasis on situational change; social learning theory highlights learning from others through observation and reinforcement rather than the direct interplay of biology and environment in situational expression.
