Cognitive function refers to the mental processes that allow individuals to perceive, think, reason, remember, and problem solve. This research area examines how these cognitive functions develop and change over time, as well as how they may be affected by various factors such as aging, neurological conditions, or environmental factors. Researchers in this field use a variety of methods such as behavioral studies, neuroimaging techniques, and cognitive assessments to better understand the underlying mechanisms of cognitive function and how to improve or preserve it. Ultimately, the goal of cognitive function research is to enhance our understanding of the brain and how it supports complex human behaviors.
