Final answer:
Short-term memory serves as an immediate holding tank for information that helps with attention span.
Step-by-step explanation:
Short-term memory (STM) is a temporary storage system that processes incoming sensory memory. Short-term memory serves as an immediate holding tank for information that helps with your attention span. It takes information from sensory memory and connects it to something already in long-term memory. Short-term memory storage lasts 15 to 30 seconds and has a capacity to hold about seven bits of information before it is forgotten or stored. Information in short-term memory can be saved to long-term memory or discarded. Overall, short-term memory plays a crucial role in our ability to pay attention and process information.
