The Hourglass

The Hourglass model describes how the brain processes sensory information and guides decision-making. It starts with broad, general data intake, then narrows through more focused analysis, and finally broadens again to plan and execute responses. Think of it like an hourglass shape: wide at the top (seeing many details), narrowing down (focused understanding), and wide at the bottom (acting or communicating). This process allows the brain to efficiently interpret complex information, prioritize important details, and generate appropriate reactions—all while adapting to new inputs dynamically.
