Korku, or fear, is an emotional response to perceived threats or danger. It can be triggered by various stimuli, such as loud noises, dark environments, or dangerous animals. Fear serves an important survival function, helping individuals react quickly to potential harm. In psychology, korku is studied to understand its effects on behavior and decision-making. It can manifest in different forms, such as phobias or anxiety disorders. While fear can be a protective mechanism, excessive korku may lead to avoidance behaviors and impact daily life.
