Attention refers to how we actively process specific information present in our environment. Attention is what allows us to tune out information, sensations, and perceptions that are not relevant at that moment in order to focus on what is important. Combined with working memory; the short-term, “erasable” memory used while dialing a new phone number; attention allows us to learn new things, or follow along in a conversation. Described by psychologists as the cognitive process of selective concentration, attention is the allocating of mental resources to help in understanding the current environment and task.
