Human cognition is the study of mental processes such as attention, memory, perception, reasoning, and decision-making that enable individuals to interact with their environment. Researchers in this field investigate how information is processed and stored in the brain, how cognitive processes develop over time, and how they are impacted by factors such as aging, neurological disorders, and psychological conditions. Understanding human cognition is essential for developing interventions to improve cognition, decision-making, and problem-solving abilities in individuals across the lifespan.
