Attention is the cognitive process described as limited, selective, and fundamental for focusing on tasks. It acts like a spotlight in the mind, deciding which information gets processed and which distractions are kept out. Because our cognitive resources are finite, attention can’t handle everything at once, so it filters and prioritizes stimuli relevant to the task at hand. This makes staying focused, maintaining performance, and resisting distractions possible.

Memory, perception, and reasoning each play different roles. Memory stores and retrieves information, perception interprets sensory input, and reasoning uses information to draw conclusions. All of these rely on attention to even occur reliably, but attention is the gatekeeper that determines what enters processing in the first place.
