Multiple Resource Theory

Multiple Resource Theory suggests that our brain has several separate pools of resources for processing different types of information—such as visual, auditory, and spatial tasks. When tasks use different resources, they can often be done simultaneously with less interference. However, if tasks rely on the same resource, they may compete for attention, making multitasking harder. This theory helps explain why some multitasking is manageable while others are overwhelmed, guiding designers to create systems that align with how our cognitive resources are naturally organized.
