Impulse, often referred to as drive, is a psychological term that describes the internal force or motivation that compels an individual to act. It can arise from various sources, including biological needs, emotional states, or external stimuli. Impulses can lead to immediate actions without much forethought, often driven by desires or instincts. In the context of behavior, impulses can be both positive and negative. For example, a hunger impulse may drive someone to seek food, while an impulse to react angrily can lead to conflict. Understanding impulses is crucial for managing behavior and making thoughtful decisions.
