Cognitive assessment is a field of research and practice that focuses on evaluating an individual's cognitive abilities, such as memory, attention, language, and executive functioning. These assessments are typically used to identify cognitive strengths and weaknesses, diagnose cognitive disorders and learning disabilities, track cognitive development over time, and inform treatment planning. Cognitive assessments can be conducted through standardized tests, interviews, observations, and neuroimaging techniques. This research area plays a crucial role in understanding and improving cognitive functioning in individuals of all ages.
