Which technique did Alfred Hitchcock popularize in thrillers?

Alfred Hitchcock is renowned for his mastery of suspense and psychological tension, which became defining characteristics of his thrillers. This approach often involves creating an atmosphere of anxiety and unease, manipulating the audience's emotions through technique and narrative. Hitchcock employed various strategies to build suspense—such as specific camera angles, innovative shot compositions, and carefully timed plot reveals. By focusing on the psychological state of his characters and building tension over time, he effectively engaged viewers, making them feel the thrill and urgency of the situation.

For example, films like "Psycho" and "Rear Window" showcase how Hitchcock engages audiences by delving into the fears and anxieties of his characters, thereby heightening the overall suspense. This use of psychological tension is often more impactful than simply relying on physical action or sensationalism, creating a deep, lingering sense of dread that resonates with viewers long after the film ends.
