broadbent's filter theory

Broadbent's filter theory suggests that our brain processes incoming sensory information through a selective filter. This filter quickly identifies and blocks out most of the irrelevant stimuli, allowing only the most important or relevant signals to reach our awareness for further processing. Essentially, it acts like a gatekeeper, helping us focus on specific sounds or sights while ignoring others, preventing overload and ensuring we can concentrate on what matters most at any given moment.
