Which characteristic of ADHD involves acting without thinking and quickly shifting activities?

The characteristic of ADHD that involves acting without thinking and quickly shifting activities is impulsivity. Impulsivity manifests as a tendency to make hasty actions that occur in the moment without considering the consequences. Individuals who exhibit impulsive behavior may interrupt others in conversations, make snap decisions, or have difficulty waiting for their turn, which can lead to challenges in social situations and academic settings. This trait often overlaps with issues in maintaining consistent attention or focus but is distinctly related to rapid responses without forethought or self-control.
