Final answer:
Attention is our ability to focus on specific stimuli, ideas, or events for further processing. Heuristics are automated shortcuts our brains use to process information efficiently.
Step-by-step explanation:
Our ability to focus on specific stimuli, ideas, or events for further processing is called attention. When our attention is focused on a task, we become less aware of other stimuli outside that focus. Our brains prefer automated shortcuts called heuristics to help us process information efficiently.
