    • Abstract:
      Cognitive function is the ability to perceive the world through processes such as language, memory, learning, perception, and reason. The performance of cognition is related to the comprehension of ideas through these processes and learning new skills to improve those areas. Cognitive function begins at birth, and cognitive abilities continue to develop throughout one’s life. The capacity to learn, however, declines over time due to aging or disease. Cognitive function is studied in such fields as cognitive science, psychology, neurology, psychiatry, and philosophy.
