Broadbent's Filter Model

Broadbent's Filter Model suggests that our brain initially filters or screens incoming sensory information, allowing only selected data to reach conscious awareness. Think of it like a security checkpoint: it quickly screens out less relevant stimuli, such as background noise, so we can focus on what's important, like a conversation or a task. This filter occurs early in processing, before we interpret or analyze what we're experiencing. The model explains how we manage to concentrate on specific stimuli in busy environments by prioritizing certain information and blocking out distractions.
