Posner's model of attention

Posner's model of attention describes how our brain focuses on certain information while ignoring other stimuli. It involves three main components: alerting (becoming ready to pay attention), orienting (directing attention to specific locations or objects), and executive control (managing and shifting attention as needed). This model highlights the importance of both location and intention in how we attend to information, suggesting that attention is not just about seeing or hearing but involves active processes that help us prioritize what is most relevant in our environment.
