Cognitive function
Cognitive function refers to the mental processes that allow individuals to perceive, understand, and interact with the world around them through abilities such as language, memory, learning, perception, and reasoning. This capacity for cognition begins at birth and evolves throughout a person’s life, although it may decline due to aging or various diseases. The study of cognitive function spans multiple disciplines, including cognitive science, psychology, neurology, psychiatry, and philosophy, originating from significant contributions by early psychologists and philosophers like Wilhelm Wundt and Mary Whiton Calkins.
Notably, Jean Piaget's work on cognitive development outlines how thought processes change from infancy to adulthood, while Carl Jung's classification of cognitive functions into categories such as thinking and feeling has influenced personality assessments like the Myers-Briggs Type Indicator (MBTI). Cognitive abilities are often evaluated using various tests, including IQ tests and the Level of Cognitive Functioning Scale (LCFS), which assess potential educational and job performance outcomes. Research in cognitive function also explores how lifestyle choices—such as sleep, diet, and physical activity—impact mental capabilities, as well as the effects of cognitive disorders like multiple sclerosis and Alzheimer's disease. Understanding cognitive function is essential for recognizing both the potential for learning and the challenges posed by cognitive decline.

Cognitive function
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.
Overview
The term cognition is used in psychology to refer to the manner in which the brain processes information, and the concept of cognitive function first received serious attention in the nineteenth century by psychologists such as Wilhelm Wundt and Hermann Ebbinghaus and philosophers such as Mary Whiton Calkins. They and other researchers examined the limits of memory and the brain’s capacity for thought and learning. During the twentieth century, psychologist Jean Piaget examined cognitive development and mental processes of the brain at birth and throughout adulthood.
One of the most common models of cognitive function came from twentieth-century Swiss psychiatrist Carl Jung, who divided cognitive function into four groups: thinking, feeling, sensing, and intuition. Jung believed that the interplay between these functions was responsible for personality and interaction with the world. These ideas later influenced researcher Isabel Briggs Myers, who developed the Myers-Briggs Type Indicator (MBTI) personality test in the 1960s. The test is designed to discover the preferences and dominant functions among cognitive traits: extraversion and introversion, sensing and intuition, thinking and feeling, and judging and perceiving. The MBTI is one of many classifications of thinking styles.
Cognitive function is assessed in numerous disciplines and is often considered alongside cognitive ability. It can be measured through such tests as the Level of Cognitive Functioning Scale (LCFS), screenings from the Diagnostic and Statistical Manual of Mental Disorders (DSM), and intelligence quotient (IQ) tests. IQ tests are designed to predict achievement in education and job performance. Additional research on cognitive function focuses on different ways to improve ability, memory, and learning, as well as how lifestyle factors such as sleep, fitness, exposure to chemicals, medicine, and diet affect cognitive function. Research has also been conducted on the potential benefits of early intervention during childhood, in infancy, and during pregnancy. Disorders such as multiple sclerosis (MS), Parkinson’s disease, Alzheimer’s disease, diabetes, and depression are known to negatively affect cognitive function.
